Answer:
d= 8.6 ft
Step-by-step explanation:
In similar triangles, the corresponding sides are in proportion.

To find the value of x,

d = 8.6 ft
I would probably just do 91 times 60 since 60 min is 1 hour
Answer:
c. 25
Step-by-step explanation:
(f ∘ g)(-2) = f(g(-2)) = f(-2-3) = (-5)² = 25
For this problem, it seems to work best to evaluate g(-2), then evaluate function f on that. (In other cases, it might be useful to simplify the composite function first.)
Divide 4w to every term separately.


48/4 = 12
w^3/w = w^2
So our first term is 12w^2.
128/4 = 32
w^2/w = w
So our second term is 32w.
4w/4w = 1
Anything divided by itself is 1.
-1/4w, this can't be simplified further, so this is our last term.
So we have:
Answer:
y=x² +6
Step-by-step explanation:
This is the only 2nd-degree equation in the group: y = x² + 6. The others are linear equations.
