Answer:
A = ((a+b)/2)h
Step-by-step explanation:
a and b are base (the top and bottom)
h is height
Answer:
1 1/2
Step-by-step explanation:
one and a half because you have a half leftover and 1 whole
Answer:

Step-by-step explanation:
We have the exponential function of the form:

And it goes through the points (0, 13) and (3, 832).
Hence, when we substitute in 0 for x, we should get 13 for y. Therefore:

Since anything to the zeroth power is 1, this yields:

So, we determined that the value of a is 13.
So, our function is now:

We will need to determine b. We know that y equals 832 when x is 3. Hence:

Divide both sides by 13:

Take the cube root of both sides:

Hence, our b value is 4.
Therefore, our entire equation is:

-3 =-2x - 7
Add 7 to both sides
4=-2x
Divide by -2
-2 = x
7/8x²-3/4x - 5/8x²-1/4x+2
x²/4-x+2
