Answer:
The total number of trees the farmer planted = 1056 trees
Step-by-step explanation:
It is given that,
A tree farmer Planet 3 types of trees on 22 acres of land and,
he planted 48 trees per acre
<u>To find total number of plants</u>
There are 22 acres of land.
In one acre he planted 48 trees.
Therefore total number of plants in 22 acers = 22 * 48 = 1056 trees
F(x) = cos x
f'(x) = -sin x
f''(x) = -cos x
f'''(x) = sin x
f''''(x) = cos x
90/4 = 22 Remainder 2
Therefore, 90th derivative of f(x) = cos x is -cos x.
