Answer:

6x² + 19x + 15

Step-by-step explanation:

2x(3x+5)+3(3x+5)

= (3x + 5) (2x + 3)

= 6x² + 9x + 10x + 15

= 6x² + 19x + 15

So, the answer is 6x² + 19x + 15

We can start by simplifying the left side of the equation using the distributive property:

2x(3x+5)+3(3x+5) = (2x)(3x) + (2x)(5) + (3)(3x) + (3)(5)

= 6x^2 + 10x + 9x + 15

= 6x^2 + 19x + 15

Now we can compare this expression with the right side of the equation, which is a polynomial in x with unknown coefficients a, b, and c:

ax^2 + bx + c

Since the two sides are equal, their corresponding coefficients must be equal as well. This gives us a system of three equations in three unknowns:

a = 6 (the coefficient of x^2)

b = 19 (the coefficient of x)

c = 15 (the constant term)

Therefore, the solution to the equation 2x(3x+5)+3(3x+5)=ax^2+bx+c is:

2x(3x+5)+3(3x+5) = 6x^2 + 19x + 15

Step-by-step explanation:

Given the position function of a particle with respect to time, find the minimum and maximum velocity the particle travels over the interval [1,7].

[tex]s(t)=t^4-16t^3+72t^2+5[/tex]

(1) - Find the velocity function of the particle

The velocity function is a derivative of the position function.

[tex]s'(t)=v(t)\\\\s(t)=t^4-16t^3+72t^2+5\\\\\Longrightarrow s'(t)=\frac{d}{dx}[t^4-16t^3+72t^2+5] \\\\\text{Use the derivative rules.}\\\\\boxed{\left\begin{array}{ccc}\text{\underline{Power Rule:}}\\\\\frac{d}{dx}[x^n]=nx^{n-1} \end{array}\right} \ \ \boxed{\left\begin{array}{ccc}\text{\underline{Constant Rule:}}\\\\\frac{d}{dx}[k]=0 \end{array}\right} \\\\\\\Longrightarrow s'(t)=(4)t^{4-1}-16(3)t^{3-1}+72(2)t^{2-1}+0\\\\\Longrightarrow s'(t)=4t^{3}-48t^{2}+144t\\\\[/tex]

[tex]\therefore \boxed{v(t)=4t^{3}-48t^{2}+144t}[/tex]

(3) - Take the derivative of v(t)

[tex]v(t)=4t^{3}-48t^{2}+144t\\\\\Longrightarrow v'(t)=12t^2-96t+144[/tex]

(4) - Let v'(t)=0 and solve for "t," these are the critical points

[tex]v'(t)=12t^2-96t+144\\\\\Longrightarrow 0=12t^2-96t+144\\\\\Longrightarrow 0=12[t^2-8t+12]\\\\\Longrightarrow 0=t^2-8t+12\\\\\Longrightarrow (t-6)(t-2)=0\\\\\therefore \text{The critical points are} \ \boxed{t=6 \ \text{and} \ t=2}[/tex]

(5) - Find the max/min values (in this case these values represent the particle's velocity) by plugging the critical points into v(t)

[tex]\text{Recall that} \ v(t)=4t^{3}-48t^{2}+144t \ \text{and} \ t=6, \ t=2\\\\\text{\underline{When t=6:}}\\\\\Longrightarrow v(6)=4(6)^{3}-48(6)^{2}+144(6)\\\\\Longrightarrow \boxed{v(6)=0 \ m/s}\\\\\text{\underline{When t=2:}}\\\\\Longrightarrow v(2)=4(2)^{3}-48(2)^{2}+144(2)\\\\\Longrightarrow \boxed{v(6)=128 \ m/s}[/tex]

Thus, at time, t=6, the particle's velocity is smallest, 0 m/s. And at time, t=2, the particle's velocity is greatest, 128 m/s.

The slope of the original line of the graph sis found to be 1 and the slope of perpendicular line is -1.

Answer: A C(t) = -(x-5)^2

Step-by-step explanation:

Answer:

C(t) = -x^2 + 5

Step-by-step explanation:

Notice how C(t) = 5 when t = 0. This means that (0, 5) is a point on C(t) and is the y-intercept, thus making the constant term (term without variable in standard form) 5. Next, notice how C(t) decreases as t increases and decreases. This means that C(t) is reflected over the x-axis such that it looks like an upside-down U shape. Thus, a negative must be applied to the term of the highest degree.

The shot put is in the air for approximately 3 seconds.

The height h (in feet) of the shot put as a function of the time t (in seconds) after it is thrown can be modeled by the equation:

h(t) = h + vt - (1/2)gt²

where v is the initial vertical velocity in feet per second, and s is the initial height in feet.

Here, the initial vertical velocity is 40 feet per second, and the initial height is 5.69 feet. Therefore, we can plug in these values to get:

h = -16t² + 40t + 5.69

To find the time that the shot put is in the air, we need to find the value of t when h = 0, since the shot put will hit the ground when its height is 0.

Therefore, we can set the equation equal to 0 and solve for t:

0 = -16t² + 40t + 5.69

Using the quadratic formula, we get:

t = (-b ± √(b² - 4ac)) / 2a

where a = -16, b = 40, and c = 5.69.

Plugging in these values, we get:

t = (-40 ± √(40² - 4(-16)(5.69))) / 2(-16)

Simplifying, we get:

t ≈ 3 or t ≈ 0.2

Since the shot put cannot be in the air for negative time, the only possible answer is t ≈ 3.

Therefore, the shot put is in the air for approximately 3 seconds.

By solving the quadratic equations,

It will take the ball 1 second to reach 18 feet

It will take the ball 1.71 seconds to be at 10 feet

It will take the ball 2.06 seconds to hit the ground

From the question, we are to determine how long it would take the ball to reach 18 feet

To determine how long it would take the ball to reach 18 feet, we will set h = 18 in the equation

The given equation is

h = -16t² + 32t + 2

Put h = 18

18 = -16t² + 32t + 2

Rearrange

16t² - 32t - 2 + 18 = 0

16t² - 32t + 16 = 0

16t² - 16t - 16t + 16 = 0

16t(t - 1) -16(t - 1) = 0

(16t - 16)(t - 1) = 0

16t - 16 = 0 OR t - 1 = 0

16t = 16 OR t = 1

t = 16/16 OR t = 1

t = 1 OR t = 1

Hence,

t = 1 second

Hence, it will take the ball 1 second to reach 18 feet

To determine how long it will take the ball to reach 10 feet, we will set h = 10

h = -16t² + 32t + 2

Put h = 10

10 = -16t² + 32t + 2

Rearrange

16t² - 32t - 2 + 10 = 0

16t² - 32t + 8 = 0

Using the quadratic formula,

t = 0.29 second OR t = 1.71 seconds

The ball will hit the ground when h = 0

Set h = 0 in the equation

h = -16t² + 32t + 2

0 = -16t² + 32t + 2

16t² - 32t - 2 = 0

Using the quadratic formula,

t = -0.06 OR t = 2.06

Since t cannot be negative,

t = 2.06 seconds

Hence, it will take 2.06 seconds for the ball to hit the ground

Point to note

We can use the Pythagorean theorem to find the length of the diagonal which is same as diameter

diameter² = side² + side²

diameter² = 2 * x²

diameter = √(2 * x²)

Since the diameter is equal to twice the radius, we have:

diameter = 2 * radius

radius = diagonal / 2

radius = √(2 * x²) / 2

Recall that  area of the circle is given by:

area = πr²

where r is the radius

Substituting the expression for the radius, we get:

64 cm² = π * (√(2 * x²) / 2)²

64 cm² = π * (2 * x² / 4)

64 cm² = π * (x² / 2)

128 = π * x²

Solving for x, we get:

So the cosine of the angle between the two planes is 8sqrt(78) / 78.

To find the cosine of the angle between two planes, we need to find the normal vectors of each plane and then use the dot product formula.

The normal vector of the first plane is <1, 1, 1>, and the normal vector of the second plane is <1, 3, 4>.

The dot product of these two vectors is:

<1, 1, 1> · <1, 3, 4> = 1(1) + 1(3) + 1(4) = 8

The magnitude of the normal vector of the first plane is:

|<1, 1, 1>| = sqrt(1^2 + 1^2 + 1^2) = sqrt(3)

The magnitude of the normal vector of the second plane is:

|<1, 3, 4>| = sqrt(1^2 + 3^2 + 4^2) = sqrt(26)

Therefore, the cosine of the angle between the two planes is:

cosθ = (normal vector of plane 1) · (normal vector of plane 2) / (magnitude of normal vector of plane 1) * (magnitude of normal vector of plane 2)

The 99% confidence interval for the population mean time spent on the internet, in minutes, is given as follows:

(48.9, 59.5).

The t-distribution is used when the standard deviation for the population is not known, and the bounds of the confidence interval are given according to the equation presented as follows:

[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]

The variables of the equation are listed as follows:

The critical value, using a t-distribution calculator, for a two-tailed 99% confidence interval, with 50 - 1 = 49 df, is t = 2.68.

The parameter values are given as follows:

[tex]\overline{x} = 54.2, s = 14, n = 50[/tex]

Then the lower bound of the interval is given as follows:

[tex]54.2 - 2.68\frac{14}{\sqrt{50}} = 48.9[/tex]

The upper bound of the interval is given as follows:

[tex]54.2 + 2.68\frac{14}{\sqrt{50}} = 59.5[/tex]
