Answer:
0.03 square meters
Step-by-step explanation:
1. convert 20 cm, 15 cm into m by dividing the number by 100 then you got 0.2 m and 0.15 m respectively
2. calculate the area by multiply 2 numbers together
0.2 × 0.15 = 0.03 square meter
Answer:
is used to prove the given equation.
Step-by-step explanation:
We have given an equation:

We will consider right hand side first
tan x can be written as:

So, on substituting tan x in the left hand side of the given equation we get:

Cancel common term from denominator and numerator which is cosx we get

And we have an identity:


Hence, right hand side is equal to
.
Answer:
k = 3.
Step-by-step explanation:
By the Factor Theorem. if x+a is a factor of f(x) then f(-a) = 0.
Here we use f(-1):
f(-1) = (-1)^3 + 2(-1) + k = 0
-1 - 2 + k = 0
k = 3.
