Answer:
r = 8
Step-by-step explanation:
They are equal through vertical angle correspondence.
So set them up to make an equation.
95 = 6r + 47
95 - 47 = 6r
48 = 6r
48 ÷ 6 = r
8 = r
Now substitute the r into the equation.
6r + 47 = 95
6(8) + 47 = 95
48 + 47 = 95
95° = 95°

Answer:
a) 30.7 million
b) 1.5% per year
c) 42.0 million
d) 2017
Step-by-step explanation:
a) The initial population is P(0) = 30.7 (million). The exponential term is 1 when t=0, so this number is the multiplier of the exponential term.
__
b) The growth factor is the base of the exponential term: 1.015. The growth rate is the difference between this and 1: 1.015 -1 = 0.015 = 1.5%.
The population is growing by 1.5% per year.
__
c) Fill in the value and do the arithmetic. t=2021 -2000 = 21.
P(21) = 30.7·1.015^21 ≈ 41.968 ≈ 42.0
The population in Canada in 2021 is predicted to be 42.0 million.
__
d) For this we need to solve for t when P(t) = 40.
40 = 30.7·1.015^t
40/30.7 = 1.015^t
Taking logarithms gives ...
log(40/30.7) = t·log(1.015)
t = log(40/30.7)/log(1.015) ≈ 17.773
In 2017, the population is predicted to be less than 40 million; in 2018, it is predicted to be more than 40 million. Canada should anticipate hitting 40 million people in 2017.

The second attachment shows the prediction described here is a little high relative to the actuals in the last few years.
Answer:
A. 1520.5 cm^2
Step-by-step explanation:
The area of a circle can be found using the following equation:
In this problem, the radius (from the center of the circle to the circumference of the circle) is 22 centimeters. Therefore, we can substitute 22 cm in for r.
r=22 cm
First, evaluate the exponent.
22 cm ^2= 22 cm * 22 cm= 484 cm^2
Multiply pi and 484
Round to the nearest tenth. The 3 in the hundredth place tell us to leave the 5 in the tenth place.
The area of the circle is 1520.5 square centimeters and A is correct.
