The fromula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have A(4, 3) and m = 3.

(0, 3)

\dfrac{3-3}{0-4}=0\neq3

(5, 0)

\dfrac{0-3}{5-4}=\dfrac{-3}{1}=-3\neq3

(3, 0)

\dfrac{0-3}{3-4}=\dfrac{-3}{-1}=3\qquad CORRECT

(0, 0)

\dfrac{0-3}{0-4}=\dfrac{-3}{-4}=\dfrac{3}{4}\neq3

<h3>Answer: (3, 0).</h3>

Answer:

Notice that the written functions are mostly incorrectly written, after a short online search i've found the correct ones, which are the ones i will write in this answer.

A general exponential equation can be written as:

f(x) = A*(r)^x

Where A is the initial value, r is the rate of growth, and x is our variable.

If r > 1,  the function represents a growth.

if 0 < r < 1, the function represents a decay.

1) f(x) = 3^x

Here we have r = 3

This is clearly larger than 1, then this function represents a growth.

2) f(x) = (0.25)^x

Here we have r = 0.25, which is smaller than 1 and larger than zero, then this function represents a decay.

3) f(x) = (2/3)^x

here we have r = 2/3 = 0.66

This is larger than zero and smaller than 1, then this function represents a decay.

4) f(x) = (3/2)^x

Here we have r = 3/2 = 1.5

This is larger than 1, then this function represents a growth,

Answer:

C\approx 5.14

Step-by-step explanation:

The circumference is the distance around a complete circle: in essence, the perimeter of a circle. The formula to find the circumference of a circle is the following:

C=(d)(\pi)

Where (d) represents the diameter, the largest cord that can be drawn in a circle, it goes from one end to another, passing through the center of the circle. The parameter (\pi) represents the number (3.1415...). However, one is given a semicircle, thus one must divide the result in two, and then add the value of the diameter to find the perimeter of the given object. Therefore the equation for the circumference of this circle is as follows:

C=\frac{(d)(\pi)}{2}+(d)

Substitute in the given value,

C=\frac{(2)(3.1415)}{2}+(2)

Simplify,

C=3.1415...+2

C=5.1415

C\approx 5.14
