Answer:
C
Step-by-step explanation:
The exponential function has standard form
y = a ![b^{x}](https://tex.z-dn.net/?f=b%5E%7Bx%7D)
Use the 2 given points to find a and b
Using (3, 182.25) , then
182.25 = a b³ → (1)
Using (2, 202.5) , then
202.5 = ab² → (2)
Divide (1) by (2)
= ![\frac{182.25}{202.5}](https://tex.z-dn.net/?f=%5Cfrac%7B182.25%7D%7B202.5%7D)
b = 0.9
Substitute b = 0.9 into (1) and solve for a
182.25 = a (0.9)³ ( divide both sides by (0.9)³
a =
= 250
Thus
f(x) = 250 ×

Answer:
b= v/7 + y/70
Step-by-step explanation:
Answer:
y= -3/4x-1
Step-by-step explanation:
The points are (8,-7) and (0,-1)
The slope is the change in Y over the change in X, so you have -3/4 as your slope.
Then, you have y=-3/4x+b
You substitute either (8,-7) or (0,-1) for X and Y in the equation, and solve it, giving you -1 for B
Answer:
A= 49.8
B= 18.5
C= 36
D= 32
Step-by-step explanation:
A= 180-130.2= 49.8
B= 90-71.5=18.5
C= 90-54=36
D= 113+35=148
180-148=32
