Evaluate the difference quotient for the given function.
kherson [118]

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

\dfrac{\frac12 \sin(2(t+h)) - \frac12 \sin(2t)}h = \dfrac{\sin(2t+2h) - \sin(2t)}{2h}

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

\dfrac{\sin(2t)\cos(2h) + \cos(2t)\sin(2h) - \sin(2t)}{2h}

or

\boxed{\sin(2t)\dfrac{\cos(2h)-1}{2h} + \cos(2t)\dfrac{\sin(2h)}{2h}}

(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).)

Twice the sum of a number and 5 is equal to three times the difference of the number and 7. Find the number.
Alexandra [31]

Step-by-step explanation:

Let the required number be x.

According to the given information:

2(x + 5) = 3(x - 7) \\  \\  \therefore \: 2x + 10 = 3x - 21 \\  \\   \therefore \: 10 + 21 = 3x -2x \\  \\ \therefore \: 31 = x \\  \\  \huge \red { \boxed{\therefore \: x = 31}}

Hence the required number is 31.
