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).)

Answer:
7b-c²
Step-by-step explanation:
7times b is 7b reduced by the square of c means minus c²
Answer:
(w^3)^8 * (w^5)^5 = w^49
Step-by-step explanation:
(w^24) * (w^25)
using exponent rule
w^24 • w^25 = w^24+25
w^49
Hey You!
6 × 30 = 90
280 - 90 = 190
190 / 2.50 = 76
We can check using multiplication.
2.50 × 76 = 190
