Answer:
x=3
Step-by-step explanation:
x^2-9
bcos g(-1)=-1
f(g)=x^2+9(-1)=0
x^2-9=0
x^2=9
x=√9
x=3
Answer:
2x² - 2x + 5
Hows your day? i had to write something else as the answer is too short lol
Assuming you mean f(t) = g(t) × h(t), notice that
f(t) = g(t) × h(t) = cos(t) sin(t) = 1/2 sin(2t)
Then the difference quotient of f is

Recall the angle sum identity for sine:
sin(x + y) = sin(x) cos(y) + cos(x) sin(y)
Then we can write the difference quotient as

or

(As a bonus, notice that as h approaches 0, we have (cos(2h) - 1)/(2h) → 0 and sin(2h)/(2h) → 1, so we recover the derivative of f(t) as cos(2t).)
First convert 5,280 ft. into inches.

5280 ft. equals 63360 inches.
Then you divide that by 42

If you're rounding to the nearest step then it would take 1509 steps to run 1 mile.
