Answer:
Step-by-step explanation:
The integral from a to 4 is ...
We want the value of this to be 12, so we can write ...
-3/2a^2 +a +20 = 12
3a^2 -2a -16 = 0 . . . . . subtract the left side and multiply by 2
(3a -8)(a +2) = 0 . . . . . factor
a = 8/3 or -2 . . . . . . . .values of a that make the factors zero
The only possible values of a are 8/3 and -2.
29.6
20% = 0.20
0.20 * 148 = 29.6
-13/1
y2 - y1 / x2 - x1 to find slope
Let's go:
Big triangle:
12 + 3x - 6 = 3x + 6
10 + 8 = 18
