Answer:
Option B is correct.
Initial amount (a) = 30 and growth factor(b) = 8.3
Step-by-step explanation:
An exponential function is of the form:
....[1]
where
a represents the initial amount
b represents the growth factor and x is the variable
Given the function: ![A(x) = 30 \cdot (8.3)^x](https://tex.z-dn.net/?f=A%28x%29%20%3D%2030%20%5Ccdot%20%288.3%29%5Ex)
On comparing given equation with [1] we get;
a = 30 and b = 8.3
Therefore, the initial amount(a) = 30 and growth factor(b) = 8.3

Multiply. Distribute 3x to all terms in the parenthesis: x and -8
3x(x) = 3x²
3x(-8) = -24x
3x² - 24x is your answer
hope this helps

Answer:
3
Step-by-step explanation:
To find the slope of a line going through two points, (x₁, y₁) and (x₂, y₂), we can use the following formula:
. Note that it doesn't really matter which points we call (x₁, y₁) or (x₂, y₂).
Let's call (x₂, y₂) = (0, 5) and (x₁, y₁) = (-2, -1). Now, we can plug in the values for x, y₁, x₂, and y₂ into the formula.
We have:
![\frac{y_{2} -y_{1} }{x_{2} -x_{1} }=\frac{5-(-1)}{0-(-2)} =\frac{5+1}{0+2} =\frac{6}{2} =3](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D%20-y_%7B1%7D%20%7D%7Bx_%7B2%7D%20-x_%7B1%7D%20%7D%3D%5Cfrac%7B5-%28-1%29%7D%7B0-%28-2%29%7D%20%3D%5Cfrac%7B5%2B1%7D%7B0%2B2%7D%20%3D%5Cfrac%7B6%7D%7B2%7D%20%3D3)
Therefore, the slope of the line is 3. Hope this helps!
