Answer:
2. 0
Explanation:
Solve f[g(6)] by finding f(x) when x = g(6).
Find g(6).
g(x) = x - 8
Set x = 6.
g(6) = 6 - 8
g(6) = -2
Find f[g(6)].
f(x) = 6x + 12
Set x = g(6).
f[g(6)] = 6[g(6)] + 12
Substitute g(6) = -2.
f(-2) = 6(-2) + 12
f(-2) = -12 + 12
f(-2) = 0
Therefore, f[g(6)] is 0.
Answer:
C y=1/2cos(x)-2
I'm not sure if it is right
My head hurts so its hard for me to concentrate
Volume of the shape
= 4ft * 4ft * 15ft
= 240ft³
First find the equation of the line:
y - b = m (X - a)
y - 5 = 2/3 (X + 2)
3y - 15 = 2 (X + 2)
3y - 15 = 2x + 4
3y = 2x + 19
Then sub the y-value of A into the equation to find X.
y = 3
3(3) = 2x + 19
9 = 2x + 19
2x = 10
X = 5
And sub the X-value of B into the equation to find y.
X = -2
3y = 2(-2) + 19
3y = -4 + 19
3y = 15
y = 5
