Given:
Radius of the circle = 4 meters
Measure of arc = 135 degrees
To find:
The area of the sector bounded by the given arc.
Solution:
Formula for area of a sector is:

Where, r is the radius and
is the central angle or measure of intercepted arc.
Putting
in the above formula, we get




Therefore, the exact area of the given sector is
square meters.
Answer:
The equivalent expression is 
Step-by-step explanation:
Given: 
We need to simplify the expression. We will distribute radical with each term inside the parentheses.

Distribute the radical



Now we will simplify the negative exponent.

Hence, The equivalent expression is 
Answer:
21/32 or 21:32
Step-by-step explanation:
I guess your function should be written this way: f(x) = 1.07ˣ , if so then:
This is an exponential function of the form aˣ, since a>0 (a=1.07) the function is growing for all value of x>0 at the rate of 7%
