Answer:28
Step-by-step explanation:
10%= 8
35%/10%= 3.5
8 x 3.5 = 28
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).)

Step-by-step explanation:
Answer:
Option B. After 20 minutes, Shari had 6 kilometers left to run
Step-by-step explanation:
Let
x ----> the time in minutes
y ----> the distance remaining in kilometers
we have the ordered pair (20,6)
That means
x=20 min
y=6 km
so
After 20 minutes, Shari had 6 kilometers left to run
