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:
37.68 ft^3
Step-by-step explanation:
The parameters used in describing a cone is radius and height
Hence
Radius= 3ft
Height = 2 ft
The volume of a cone is given as
substitute
Hence the volume is 37.68 ft^3
Answer:
Our total amount value is $4.86.
Step-by-step explanation:
The total amount given is $30.
Now 8 % of $30 =
or, 8% of $30 = $2.4
Now adding $30 and $2.4,
$ 30 + $2.4 = $32.4
Finding 15% of the total $32.4,
we get
or, 15% of $32.4 = $4.86
hence, our total amount value is $4.86.
