Answer:
22
Step-by-step explanation:
Start:
Beth's points = 0
Round 1:
Beth's points = -3
Round 2:
Beth's points = -3 + 28 which is 25
Round 3:
Beth's points = 25 - 3 which is 22

Area = pi * r^2, right:
616 = 3.1416 * r^2, r^2 = 616/3.1416 = 196.07, r = sqrt(196.07) = 14.002 meters.
Looks like it was written to be almost 14. The answer is 14.002 m, maybe rounded to just 14 m
Hello,
If the rate of return on an investment was 3% and the inflation rate was also 3%, then your buying power would remain the same. The two equal values would cancel each other out.
Imagine being given $300 and than having to pay $300, you are back where you started.
Good luck,

Answer:
f(-1) = 2
f(0) = 3
Step-by-step explanation:
f(a) = 3a - a²
- f(4)= 3*4-4²= -4 ⇒ correct
- f(3)= 3*3-3²= 0 ⇒ correct
- f(-1) = 3*(-1)-(-1)²=-3+1= -2 ⇒ incorrect
- f(0) = 3*0-0²= 0 ⇒ incorrect
- f(-5) = 3*(-5)-(-5)²= -15-25= -40 ⇒ correct
Answer:
6
Step-by-step explanation:
Given information:
Interior angle of a polygon cannot be more that 180°.
One interior angle =
Other interior angles are =
Let n be the number of sides of the polygon.
Sum of interior angles is
Combine like terms.
.... (1)
If a polygon have n sides then the sum of interior angles is
.... (2)
Equating (1) and (2) we get
Isolate variable terms.
Divide both sides by 52.
Therefore the number of sides of the polygon is 6.
