The series solution of the differential equation is,
[tex]$$y(x)=a_0\left(1-\frac{x^2}{2}+\frac{x^4}{4!}-\frac{x^6}{6!}+\cdots\right)+a_1\left(x-\frac{x^3}{3!}+\frac{x^5}{5!}-\frac{x^7}{7!}+\cdots\right)$$[/tex]
To find the series solution for the given differential equation, we need to express it in the form of power series.[tex]$$y''+xy'+y=0$$$$\sum_{n=0}^{\infty}(n+2)(n+1)a_{n+2}x^n+\sum_{n=0}^{\infty}(n+1)a_{n+1}x^{n+1}+\sum_{n=0}^{\infty}a_{n}x^{n}=0$$[/tex]
The above equation has no constant term, so we can drop the third sum and change the limits of the first sum by taking n=1 as its first term.[tex]$$ \sum_{n=1}^{\infty}(n+2)(n+1)a_{n+2}x^{n}+\sum_{n=0}^{\infty}(n+1)a_{n+1}x^{n+1}=0 $$[/tex]
Now we can shift the index of the second sum to get it in the same form as the first sum.
[tex]$$\sum_{n=1}^{\infty}(n+2)(n+1)a_{n+2}x^{n}+\sum_{n=1}^{\infty}na_{n}x^{n}=0$$[/tex]
Comparing the coefficients of x^n on both sides,
[tex]$$(n+2)(n+1)a_{n+2}+na_{n}=0$$[/tex]
We obtain the recurrence relation.
[tex]$$a_{n+2}=-\frac{n}{(n+2)(n+1)}a_n$$[/tex]
We can start from a0 and get all other coefficients using the recurrence relation.[tex]$$a_2=-\frac{0}{2*1}a_0=0$$$$a_4=-\frac{2}{4*3}a_2=0$$$$a_6=-\frac{4}{6*5}a_4=0$$$$\vdots$$[/tex]
We can see that the even terms of the series are all zero. Similarly, we can start from a1 to get all other odd coefficients.
[tex]$$a_3=-\frac{1}{3*2}a_1$$$$a_5=-\frac{3}{5*4}a_3$$$$a_7=-\frac{5}{7*6}a_5$$$$\vdots$$[/tex]
Thus the series solution is,
[tex]$$y(x)=a_0\left(1-\frac{x^2}{2}+\frac{x^4}{4!}-\frac{x^6}{6!}+\cdots\right)+a_1\left(x-\frac{x^3}{3!}+\frac{x^5}{5!}-\frac{x^7}{7!}+\cdots\right)$$[/tex]

The work done by the force field F on a particle moving along the circle C is zero. The force field F is conservative, which means that there exists a potential function ϕ such that F = −∇ϕ.
The potential function for F is given by
ϕ(x, y) = −x^2/2 - y^2/2
The work done by a force field F on a particle moving from point A to point B is given by
W = ∫_A^B F · dr
In this case, the particle starts at the point (a, 0) and ends at the point (a, 0). The integral can be evaluated as follows:
W = ∫_a^a F · dr = ∫_0^{2π} −∇ϕ · dr = ∫_0^{2π} (-x^2/2 - y^2/2) · (-a^2 sin^2 t - a^2 cos^2 t) dt = 0

Use the position function s(t)= 96t/√t^2+3 to find the velocity at time t=2 Enter an exact answer, do not
use decimal approximation. (Assume units of meters and seconds.)
V(2) = m/s
The velocity at time t = 2 is (96√7 - 768) / 7 m/s.
What is the velocity at time t = 2?To find the velocity at time t = 2 using the position function s(t) = 96t/√(t² + 3), we need to find the derivative of the position function with respect to time.
The derivative of s(t) with respect to t gives us the velocity function v(t).
Let's differentiate s(t) using the quotient rule and chain rule:
s(t) = 96t/√(t² + 3)
Using the quotient rule:
v(t) = [96(√(t² + 3))(1) - 96t(1/2)(2t)] / (t² + 3)
Simplifying:
v(t) = (96√(t² + 3) - 192t²) / (t² + 3)
Now we can find the velocity at t = 2 by substituting t = 2 into the velocity function:
v(2) = (96√(2² + 3) - 192(2)²) / (2² + 3)
v(2) = (96√(4 + 3) - 192(4)) / (4 + 3)

Use Modular Arithenetic to prove that 5/p^6- p^z? for every integer p?
Given that p is any integer, it is required to prove that 5/p^6- p^z.How to use modular arithmetic to prove this is explained below:
First, let's express the given expression using modular arithmetic.5/p6 - pz can be written as 5(p6 - z) /p6.Since p6 is a multiple of p, we can say that p6 = pm for some integer m.Substituting this in the above expression,
we get:5(p6 - z) /p6 = 5(pm - z) /pm
We can now use modular arithmetic to prove that this expression is equivalent to 0 (mod p).
Since p is a factor of pm, we can say that 5(pm - z) is divisible by p. Therefore, 5(pm - z) is equivalent to 0 (mod p).
Thus, we have proven that 5/p^6- p^z is equivalent to 0 (mod p) for every integer p.

Connie’s first three test scores are 79%, 87%, and 98%. What must she score on her fourth test to have an overall mean of exactly 90%?
Step-by-step explanation:
You want the average of FOUR test scores to equal 90 :
( 79 + 87 + 98 + x ) / 4 = 90 ( assuming they are all weighted equally)
x = 90*4 - 79 - 87 - 98 = 96 % needed
A 60lb weight stretches a spring 6 feet. The weight hangs vertically from the spring and a damping force numerically equal to 5√√3 times the instantaneous velocity acts on the system. The weight is released from 3 feet above the equilibrium position with a downward velocity of 13 ft/s. (a) Determine the time (in seconds) at which the mass passes through the equilibrium position. (b) Find the time (in seconds) at which the mass attains its extreme displacement from the equilibrium position
To solve this problem, we can use the equation of motion for a damped harmonic oscillator
m*y'' + c*y' + k*y = 0,
where m is the mass, y is the displacement from the equilibrium position, c is the damping coefficient, and k is the spring constant.
Given:
m = 60 lb,
y(0) = 3 ft,
y'(0) = -13 ft/s,
c = 5√√3,
k = (60 lb)/(6 ft) = 10 lb/ft.
Converting the units:
m = 60 lb * (1 slug / 32.2 lb·ft/s²) = 1.86 slug,
k = 10 lb/ft * (1 slug / 32.2 lb·ft/s²) = 0.31 slug/ft.
The equation of motion becomes:
1.86*y'' + 5√√3*y' + 0.31*y = 0.
(a) To determine the time at which the mass passes through the equilibrium position, we need to find the time when y = 0.
Substituting y = 0 into the equation of motion, we get:
1.86*y'' + 5√√3*y' + 0.31*0 = 0,
1.86*y'' + 5√√3*y' = 0.
The solution to this homogeneous linear differential equation is given by:
y(t) = c₁*e^(-αt)*cos(βt) + c₂*e^(-αt)*sin(βt),
where α = (5√√3) / (2 * 1.86) and β = sqrt((0.31 / 1.86) - (5√√3)^2 / (4 * 1.86^2)).
Since the mass starts from 3 ft above the equilibrium position with a downward velocity, we can determine that c₁ = 3.
To find the time at which the mass passes through the equilibrium position (y = 0), we set y(t) = 0 and solve for t:
c₁*e^(-αt)*cos(βt) + c₂*e^(-αt)*sin(βt) = 0.
At the equilibrium position, the cosine term becomes zero: cos(βt) = 0.
This occurs when βt = (2n + 1) * π / 2, where n is an integer.
Solving for t, we have:
t = ((2n + 1) * π / (2 * β)), where n is an integer.
(b) To find the time at which the mass attains its extreme displacement from the equilibrium position, we need to find the maximum value of y(t).
The maximum value occurs when the sine term in the solution is at its maximum, which is 1.
Thus, c₂ = 1.
To find the time when the mass attains its extreme displacement, we set y'(t) = 0 and solve for t:
y'(t) = -α*c₁*e^(-αt)*cos(βt) + α*c₂*e^(-αt)*sin(βt) = 0.
Simplifying the equation, we have:
α*c₂*sin(βt) = α*c₁*cos(βt).
This occurs when the tangent term is equal to α*c₂ / α*c₁:
tan(βt) = α*c₂ / α*c₁.
Solving for t, we have:
t = arctan(α*c₂ / α*c₁)
/ β.
Substituting the given values and solving numerically will give the values of t for both (a) and (b).

Round all answers to 4 decimal places where possible, a. What is the distribution of X? X - NO b. Find the probability that a randomly selected bag of marijuana sold on the street will have a THC content greater than 9.1. c. Find the 64th percentile for this distribution. % Hint: Helpful videos: • Find a Probability [+] 7 Finding a Value Given a Probability [+] Hint Submit
The distribution of X is normally distributed.
The given information states that the THC content of marijuana sold on the street is normally distributed with a mean of 9.8% and a standard deviation of 2%. This means that the THC content follows a bell-shaped curve, where the majority of values will be around the mean of 9.8%.
In statistical terms, we can represent the THC content as a random variable X. Since X is normally distributed, we can use the notation X ~ N(9.8, 0.02^2), where N represents the normal distribution, 9.8 is the mean, and 0.02 is the standard deviation.
To find the probability that a randomly selected bag of marijuana sold on the street will have a THC content greater than 9.1, we need to calculate the area under the curve to the right of 9.1. This can be done by finding the z-score corresponding to 9.1, which measures the number of standard deviations a value is away from the mean. Using the formula z = (X - μ) / σ, we can calculate the z-score as (9.1 - 9.8) / 0.02 = -3.5.
Now, we can use a standard normal distribution table or a calculator to find the probability associated with a z-score of -3.5. The probability corresponds to the area under the curve to the right of the z-score. In this case, the probability is approximately 0.0002327, rounded to 4 decimal places. Therefore, the probability that a randomly selected bag of marijuana sold on the street will have a THC content greater than 9.1 is approximately 0.0002.

determine whether the series is convergent or divergent. [infinity] n sqrt2 n = 1
The given series, ∑ (n = 1 to ∞) sqrt(2)^n, is divergent.
To determine the convergence or divergence of the series, we need to analyze the behavior of the general term. In this case, the general term is given by n√(2n).
We can use the limit comparison test to examine the convergence of the series. Let's consider the series ∑n√(2n) and compare it with a known series that has a known convergence behavior. We'll choose the harmonic series ∑1/n as our comparison series.
By taking the limit of the ratio of the two series as n approaches infinity, we have:
lim(n→∞) (n√(2n))/(1/n)
Applying algebraic simplification and simplifying the expression inside the limit, we get:
lim(n→∞) (n√(2n))/(1/n) = lim(n→∞) (n√(2n)) * (n/1)
= lim(n→∞) n^2 * √(2n)
= lim(n→∞) √(2n^3)
Now, as n approaches infinity, √(2n^3) also approaches infinity. Thus, the limit of the ratio is infinity.
According to the limit comparison test, if the limit of the ratio is a positive finite number, the two series have the same convergence behavior. If the limit is zero, the series are both convergent or both divergent. However, if the limit is infinity, the series diverge.
In this case, the limit is infinity, indicating that the series ∑n√(2n) diverges. Therefore, the given series is divergent.

4) Create a maths problem and model solution corresponding to the following question: "Evaluate the following integral using trigonometric substitution" he integral should make use of the substitution x = atanθ, and also require a second substitution to solve. The square root component should be multiplied by a polynomial.
We will evaluate an integral using trigonometric substitution and a second substitution. The integral will involve the substitution x = atanθ and a square root component multiplied by a polynomial.
Let's consider the integral ∫ √(x^2 + 1) * (x^3 + 2x) dx. We will evaluate this integral using trigonometric substitution x = atanθ.
First, we substitute x = atanθ. Then, we have dx = sec²θ dθ and x^2 = (tanθ)^2.
Substituting these values into the integral, we have:
∫ √((tanθ)^2 + 1) * ((tanθ)^3 + 2tanθ) * sec²θ dθ.
Simplifying the expression, we get:
∫ √(tan²θ + 1) * (tan³θ + 2tanθ) * sec²θ dθ.
Next, we use the trigonometric identity sec²θ = 1 + tan²θ to rewrite the integral as:
∫ √(tan²θ + 1) * (tan³θ + 2tanθ) * (1 + tan²θ) dθ.
Expanding the expression further, we obtain:
∫ (√(tan²θ + 1) * tan³θ + 2√(tan²θ + 1) * tanθ + √(tan²θ + 1) * tan⁵θ + 2√(tan²θ + 1) * tan³θ) dθ.
At this point, we can simplify the integral by using a second substitution. Let's substitute tanθ = u. Then, sec²θ dθ = du.
Now, the integral becomes:
∫ (√(u² + 1) * u³ + 2√(u² + 1) * u + √(u² + 1) * u⁵ + 2√(u² + 1) * u³) du.
Integrating this expression, we obtain the antiderivative F(u).
Finally, we substitute back u = tanθ and replace θ with the inverse tangent to obtain the antiderivative in terms of x.

The zeros of the function are: -4i, 4i, -3, 2 and (7 - 3√17)/4. Given function is h(x) = 4x⁵ + 6x⁴ + 36x³ + 54x² - 448x - 672. Zero is -4i. Therefore, the remaining zeros of the given function can be determined by dividing the given polynomial function by (x - zero).Since the given zero is -4i.
We get:4x⁴ - 14x³ - 14x² + 66x + 168 - 64i.The quotient obtained after division is 4x⁴ - 14x³ - 14x² + 66x + 168 and -64i is the remainder. Since the degree of the quotient obtained is four, we need to find its remaining zeros which are complex or real.For finding the remaining zeros, we need to solve the equation: 4x⁴ - 14x³ - 14x² + 66x + 168 = 0.Thus, the remaining zeros are real and can be found by factoring the polynomial:4x⁴ - 14x³ - 14x² + 66x + 168= 2(x - 2)(x + 3)(2x² - 7x - 14).

Use the fact that the vector product is distributive over addition to show that (a - b) x (a + b) = 2(axb) By considering the definition of a Xb prove that k(a X b) = (ka) × b = ax (kb). 7 If a, b and c form the triangle shown, prove that axb=bXc=cXa [Hint: consider the obvious relation between a, b and c then construct suitable vector products.]
To show that (a - b) x (a + b) = 2(axb), we can expand both sides using the distributive property of the vector product:
(a - b) x (a + b) = a x (a + b) - b x (a + b)
Expanding further:
= a x a + a x b - b x a - b x b
Since the vector product is anti-commutative (b x a = -a x b), we can simplify the expression:
= a x a + a x b - (-a x b) - b x b
= a x a + a x b + a x b - b x b
= a x a + 2(a x b) - b x b
Now, using the fact that a x a = 0 (the vector product of a vector with itself is zero), we have:
= 0 + 2(a x b) - b x b
= 2(a x b) - b x b
Since the vector product is also anti-commutative (b x b = -b x b), we can simplify further:
= 2(a x b) + b x b
= 2(a x b) + 0
= 2(a x b)
Therefore, we have shown that (a - b) x (a + b) = 2(axb).
Now, let's prove the relation k(a x b) = (ka) x b = a x (kb) using the definition of the vector product.
Using the distributive property of scalar multiplication, we have:
k(a x b) = k[(a₂b₃ - a₃b₂)i - (a₁b₃ - a₃b₁)j + (a₁b₂ - a₂b₁)k]
Expanding further:
= [(ka₂b₃ - ka₃b₂)i - (ka₁b₃ - ka₃b₁)j + (ka₁b₂ - ka₂b₁)k]
= [(ka₂b₃)i - (ka₃b₂)i + (ka₁b₃)j - (ka₃b₁)j + (ka₁b₂)k - (ka₂b₁)k]
Rearranging the terms:
= [(ka₂b₃)i + (ka₁b₃)j + (ka₁b₂)k] - [(ka₃b₂)i + (ka₃b₁)j + (ka₂b₁)k]
Now, considering the definition of the vector product a x b, we can rewrite the expression as:
= (ka) x b - a x (kb)
Therefore, we have shown that k(a x b) = (ka) x b = a x (kb).
Finally, let's prove that axb = bxc = cxa using the given triangle formed by vectors a, b, and c.
Using the definition of the vector product, we have:
axb = (a₂b₃ - a₃b₂)i - (a₁b₃ - a₃b₁)j + (a₁b₂ - a₂b₁)k
bxc = (b₂c₃ - b₃c₂)i - (b₁c₃ - b₃c₁)j + (b₁c₂ - b₂c₁)k

Answer = 6
The answer to the given puzzle is 6. The answer to the missing number is calculated by multiplying the first number of each column by 2 and adding 3 to it.
To solve this puzzle, we need to find the pattern of numbers being used in each column of the given numbers. We need to apply the same pattern to find the missing number. The first step is to identify the pattern being followed in each column. If we look at the first column, we see that the first number (3) is multiplied by 2, and then 3 is added to the answer. Therefore, the answer is ((3 x 2) + 3) = 9. Now, if we look at the second column, the first number (0) is multiplied by 2, and then 3 is added to the answer. Therefore, the answer is ((0 x 2) + 3) = 3. Similarly, we can find that the pattern of each column follows the same sequence and hence can be used to find the answer for the missing number. The third column has a missing number and is represented by a question mark. Therefore, we need to apply the pattern used in the third column to find the missing number. We know that the first number (1) is multiplied by 2, and then 3 is added to the answer. Therefore, the answer is ((1 x 2) + 3) = 5. Hence, the missing number in the third column is 6.
Therefore, the answer to the given puzzle is 6. The solution is based on a pattern that is being used in each column of the given numbers. We can apply the same pattern to find the missing number, which is represented by a question mark. The answer to the missing number is calculated by multiplying the first number of each column by 2 and adding 3 to it.

how is x-y+z the same as x-(y+z) or (x-y)+z?
The expression "x - y + z" can be simplified and rearranged using the associative property and commutative property of addition. Let's break it down step by step:
1. x - y + z
According to the associative property of addition, the grouping of terms does not affect the result when only addition and subtraction are involved. Therefore, we can choose to group "y" and "z" together:
2. x + (-y + z)
Next, using the commutative property of addition, we can rearrange the terms "-y + z" as "z + (-y)":
3. x + (z + (-y))
Now, we have the expression "x + (z + (-y))". According to the associative property of addition, we can group "x" and "z + (-y)" together:
4. (x + z) + (-y)
Finally, we can rewrite the expression as "(x + z) - y", which is equivalent to "(x - y) + z":
5. (x + z) + (-y) = (x - y) + z
Therefore, "x - y + z" is indeed the same as both "x - (y + z)" and "(x - y) + z" due to the associative and commutative properties of addition.
A random variable X has a normal probability distribution with mean 30 and (12 mark standard deviation 1.5. Find the probability that P(27
To find the probability that [tex]\(P(27 < X < 33)\)[/tex], where [tex]\(X\)[/tex] is a normally distributed random variable with mean 30 and standard deviation 1.5, we can use the properties of the standard normal distribution.
First, we need to standardize the values 27 and 33. We can do this by subtracting the mean and dividing by the standard deviation:
[tex]\(z_1 = \frac{{27 - \mu}}{{\sigma}} = \frac{{27 - 30}}{{1.5}} = -2\)\(z_2 = \frac{{33 - \mu}}{{\sigma}} = \frac{{33 - 30}}{{1.5}} = 2\)[/tex]
Next, we can use a standard normal distribution table or a calculator to find the corresponding probabilities for these standardized values.
Using a standard normal distribution table, the probability of a standard normal random variable falling between -2 and 2 is approximately 0.9545.
Therefore, the probability that [tex]\(27 < X < 33\)[/tex] is approximately 0.9545.

Question 8 (3 points) What are the different ways to solve a quadratic equation? Provide a diagram with your explanation.
This gives us the solutions x = -2 + √11 and x = -2 - √11. A diagram to represent the different methods of solving a quadratic equation is not necessary.
There are different ways to solve a quadratic equation: factoring, using the square root property, completing the square, and using the quadratic formula. A quadratic equation is an equation that can be written in the standard form ax² + bx + c = 0, where a, b, and c are real numbers.
1. Factoring: This is the simplest method of solving a quadratic equation. We factor the quadratic equation into a product of two binomials. For example, let's solve the equation x² + 7x + 10 = 0.
We can factor the quadratic equation as (x + 5)(x + 2) = 0. We can then solve for x by setting each factor to zero and solving for x.
Therefore, x + 5 = 0 or x + 2 = 0. This gives us the solutions x = -5 and x = -2.
2. Using the square root property: This method can be used to solve a quadratic equation of the form x² = a. For example, let's solve the equation x² = 25.
We take the square root of both sides of the equation: x = ±√25. This gives us the solutions x = 5 and x = -5.
3. Completing the square: This method involves rewriting the quadratic equation in the form (x + p)² = q, where p and q are constants. For example, let's solve the equation x² + 4x - 5 = 0.
We add 5 to both sides of the equation: x² + 4x = 5. We then complete the square by adding (4/2)² = 4 to both sides of the equation: x² + 4x + 4 = 9.
We can then rewrite the left-hand side of the equation as (x + 2)² = 9. Taking the square root of both sides of the equation gives us x + 2 = ±3.
This gives us the solutions x = 1 and x = -5.
4. Using the quadratic formula: This method involves using the quadratic formula to solve the quadratic equation. The quadratic formula is given by: x = (-b ± √(b² - 4ac))/2a.
For example, let's solve the equation x² + 4x - 5 = 0 using the quadratic formula. We have a = 1, b = 4, and c = -5.
Substituting these values into the quadratic formula, we get:
x = (-4 ± √(4² - 4(1)(-5)))/2(1)
= (-4 ± √44)/2
Simplifying, we get x = (-4 ± 2√11)/2.
Dividing both sides of the equation by 2, we get:
x = -2 ± √11.
This gives us the solutions x = -2 + √11 and x = -2 - √11.

To find fx and fy for the function f(x, y) = 13(7x - 6y + 12)7, we need to differentiate the function with respect to x and y, respectively.
To find fx, we differentiate the function f(x, y) with respect to x while treating y as a constant. Using the power rule, the derivative of
(7x - 6y + 12) with respect to x is simply 7. Therefore,
fx(x, y) = 7 ×13(7x - 6y + 12)6.
To find fy, we differentiate the function f(x, y) with respect to y while treating x as a constant. Since there is no y term in the function, the derivative of (7x - 6y + 12) with respect to y is 0. Therefore, fy(x, y) = 0.
Hence fx(x, y) = 7 × 13(7x - 6y + 12)6, and fy(x, y) = 0. The partial derivative fx represents the rate of change of the function with respect to x, while fy represents the rate of change of the function with respect to y.

Technique To Solve Use Laplace Transformation The Initial Value Problem Below.
y"-4y = eˆ3t
y (0) = 0
y' (0) = 0
To solve the initial value problem y'' - 4y = e^(3t) with the initial conditions y(0) = 0 and y'(0) = 0 using Laplace transformation, we follow these steps:
Apply the Laplace transform to both sides of the differential equation:
Taking the Laplace transform of the given differential equation, we get s^2Y(s) - 4Y(s) = 1/(s - 3), where Y(s) represents the Laplace transform of y(t) and s is the Laplace variable.
Solve the algebraic equation in the Laplace domain:
Rearranging the equation, we have Y(s) * (s^2 - 4) = 1/(s - 3). Solving for Y(s), we find Y(s) = 1/[(s - 3)(s^2 - 4)].
Decompose Y(s) using partial fraction decomposition:
Express Y(s) as a sum of partial fractions: Y(s) = A/(s - 3) + (Bs + C)/(s^2 - 4), where A, B, and C are constants to be determined.
Determine the values of A, B, and C:
To find the values of A, B, and C, we equate the coefficients of like powers lof s on both sides of the equation. Multiplying both sides by the common denominator, we can compare the coefficients and solve for the constants A, B, and C.
Take the inverse Laplace transform:
Having obtained the decomposition of Y(s) and determined the values of A, B, and C, we can now take the inverse Laplace transform to obtain the solution y(t) in the time domain. Utilize Laplace transform tables or a computer algebra system to find the inverse Laplace transform.
Apply the initial conditions:
To find the specific solution satisfying the initial conditions y(0) = 0 and y'(0) = 0, substitute these values into the obtained solution y(t) and solve for any remaining unknowns. By substituting t = 0 into y(t) and its derivative, we can determine the values of A, B, and C, thereby obtaining the unique solution to the initial value problem.

The equation of the line perpendicular to 3x + 5y = 10 and passing through the point (3,-8) is y = (5/3)x - 13.
How to find the equation of a line perpendicular to 3x + 5y = 10 and passing through the point (3,-8)?To find the equation of a line perpendicular to 3x + 5y = 10, we first need to determine the slope of the given line.
Rearranging the equation into slope-intercept form (y = mx + b), we can isolate y to obtain y = -(3/5)x + 2. The slope of the given line is -3/5.
For a line perpendicular to the given line, the slopes are negative reciprocals. Therefore, the slope of the perpendicular line is 5/3.
Next, we substitute the coordinates of the given point (3,-8) into the point-slope form of a line (y - [tex]y_1[/tex] = m(x - [tex]x_1[/tex])), where [tex](x_1, y_1)[/tex] represents the coordinates of the point.
Plugging in the values, we have y + 8 = (5/3)(x - 3).
To convert the equation to slope-intercept form, we simplify and isolate y. Distributing (5/3) to (x - 3) gives y + 8 = (5/3)x - 5. Rearranging the equation, we have y = (5/3)x - 13.
Therefore, the equation of the line perpendicular to 3x + 5y = 10 and passing through the point (3,-8) is y = (5/3)x - 13.
