What value of x makes this equation true? 0.17x 0.03 0.03x - 0.002​

The value of r which is the decay rate is calculated as: -0.0203

The equation for "continual" growth (or decay) is given by the expression:

[tex]A = Pe^{rt}[/tex]

where:

A is the ending amount,

P is the beginning amount (principal, in the case of money)

r  is the growth or decay rate (expressed as a decimal),

t is the time (in whatever unit was used on the growth/decay rate).

We are given that:

A = 70000

P = 93000

t = 14

Thus:

70000 = 93000 * [tex]e^{14r}[/tex]

70/93 = * [tex]e^{14r}[/tex]

14 r = In (70/93)

14r = -0.2841

The number of terms n of the geometric progression is n = 12

Given data ,

Let the geometric progression be represented as A

Now , the value of A is

10 + 30 + 90 + .... = 2657200

And , let the number of terms be n

common ratio r = 30 / 10 = 3

where sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )

On simplifying , we get

2657200 = 10 ( 3ⁿ - 1 ) / ( 2 )

Divide by 5 on both sides , we get

3ⁿ - 1 = 5,31,440

Adding 1 on both sides , we get

3ⁿ = 5,31,441

Taking log on both sides , we get

n = 12

Hence , the number of terms of GP is n = 12

To solve for x in the equation −1.5x−2.7=20.1+4.5x, we need to isolate x on one side of the equation. We can do this by adding 1.5x to both sides of the equation and adding 2.7 to both sides of the equation, which gives us:

-1.5x - 2.7 + 1.5x = 20.1 + 4.5x + 1.5x

Simplifying the left side of the equation and combining like terms on the right side of the equation gives us:

-2.7 = 6x + 20.1

Subtracting 20.1 from both sides of the equation gives us:

-22.8 = 6x

Dividing both sides of the equation by 6 gives us:

x = -3.8

Therefore, the value of x that satisfies the equation is -3.8.

The solution of the function is as follows:

f(3) = 16

h(0) = -4

h(g(x)) = 3x + 5

g(y) = y + 3

f(x) - h(x) =  x² - x + 5

A function relates input and output. In other words, a function is an expression that defines a relationship between one variable (the independent variable) and another variable(dependent variable).

Therefore, let's solve the function as follows:

f(x) = x² + 2x + 1

g(x) = x + 3

h(x) = 3x - 4

Therefore,

f(3) =  (3)² + 2(3) + 1 = 9 + 6 + 1 = 16

h(0) = 3(0) - 4 = -4

h(g(x)) = 3(x + 3) - 4 = 3x + 9 - 4 = 3x + 5

g(y) = y + 3

f(x) - h(x) =  x² + 2x + 1  - (3x - 4) =  x² + 2x + 1  - 3x + 4 = x² - x + 5

Answer: $0.0195

Step-by-step explanation: To find the price per ounce of apple juice, we need to divide the total cost by the number of ounces.

Price per ounce = Total cost / Number of ounces

Here, the total cost is $2.50 and the number of ounces is 128.

Price per ounce = $2.50 / 128 ounces

Price per ounce = $0.0195

Therefore, the price per ounce of apple juice is $0.0195, which is approximately 2 cents per ounce.

Answer: $0.0195 per ounce

Step-by-step explanation:

We will create a proportion to help us solve this question.

➜ To do this, we will set two fractions equal to each other with the dollar amount in the numerator and the ounce amount in the denominator.

[tex]\displaystyle \frac{\$2.50}{128\;ounces} =\frac{\$x}{1\;ounce}[/tex]

Cross-multiply:

      128x = $2.50

Divide both sides of the equation by x:

Time is usually represented by the x axis

Step-by-step explanation:

To determine the constant of proportionality (k) in a proportional relationship, we need to compare corresponding values of x and y and calculate the ratio between them.

Let's examine the given values:

2. UX: x 6 15 9 y 42 200

To find the constant of proportionality (k), we can take any pair of corresponding values and calculate their ratio. Let's choose the first pair: (6, 42).

k = y / x

k = 42 / 6

k = 7

So, the constant of proportionality (k) is 7.

Now, let's find the missing values for the second set of values:

d. X: 14 y: 21 6 15 3 7 8

Since we know the constant of proportionality is 7, we can calculate the missing values of y by multiplying each corresponding x value by 7.

Missing values for y:

- For x = 21, y = 21 * 7 = 147

- For x = 6, y = 6 * 7 = 42

- For x = 15, y = 15 * 7 = 105

- For x = 3, y = 3 * 7 = 21

- For x = 7, y = 7 * 7 = 49

- For x = 8, y = 8 * 7 = 56

Therefore, the missing values of y are: 147, 42, 105, 21, 49, and 56.

The symmetric equations for the line are:

(36x + 40y - 28z - 100) / 0 = (x-5) / -6 = (y-8) / -5 = (z+2) / 7

To find the parametric equations for the line passing through A(5, 8, -2) and B(-1, 3, 5), we can use the vector equation:

r = A + t(B-A)

where r is the position vector of any point on the line, t is a scalar parameter, and A and B are the given points. Substituting the values, we get:

r = (5, 8, -2) + t((-1)-5, 3-8, 5-(-2))

r = (5, 8, -2) + t(-6, -5, 7)

The parametric equations for the line are:

x = 5 - 6t
y = 8 - 5t
z = -2 + 7t

To find the symmetric equations, we can use the fact that any point on the line is equidistant from points A and B. Thus, the distance from a point (x, y, z) to A must be the same as the distance from the same point to B. Using the distance formula, we get:

√[(x-5)² + (y-8)² + (z+2)²] = √[(x+1)² + (y-3)² + (z-5)²]

Calculus a broad subject that covers many topics such as derivatives, integrals, limits, and functions.

Calculus is a branch of mathematics that focuses on the study of change and motion. It provides a framework for understanding and analyzing quantities that vary continuously. The two main branches of calculus are differential calculus and integral calculus.

Differential calculus deals with the concept of derivatives. A derivative measures how a function changes as its input (usually denoted as x) changes. Geometrically, the derivative represents the slope of a function at a particular point. It can also be interpreted as the instantaneous rate of change of a function at a given point. Derivatives have various applications, such as determining the maximum or minimum values of functions, analyzing the behavior of functions, and solving optimization problems.

Integral calculus, on the other hand, focuses on the concept of integrals. An integral is a mathematical operation that measures the accumulation of quantities or the area under a curve. It essentially reverses the process of differentiation. Integrals can be used to compute the total change or accumulation of a quantity over a given interval, find the area of irregular shapes, and solve problems involving rates of change.

Calculus plays a fundamental role in many scientific and engineering disciplines. It is used extensively in physics, engineering, economics, computer science, and many other fields to model and solve real-world problems involving continuous change. The study of calculus also forms the basis for higher-level mathematics such as differential equations, vector calculus, and multivariable calculus.
