Answer:
Area: pir^2
r=4
4pi^2
if pi=3.14
then the area is 50.24ft^2
Circumference: pi x d
d=8
8pi
if pi=3.14
then the circumference is 25.12ft.
Answer:
The more often your interest compounds, the more interest you'll earn on your investment. It's easy to see that money grows more quickly when it's earning compound interest than when it's earning simple interest
Step-by-step explanation:
Local Calls = 36
Distance calls = 20
Ratio would be: = 36/20 = 18/10 = 9/5
In short, Your Answer would be Option A
Hope this helps!
The choices are points of a function that lies at coordinates (x,y). Just do trial and error with each choice and see which applies
a) x = 0, y = 0
-5(0)^2 + 20(0) - 17 > 0
-17 > 0 (not true)
b) x = 2, y= 2
-5(2)^2 + 20(2) - 17 > 2
3 > 2 (true)
c) x =5, y=2
-5(5)^2 + 20(5) - 17 > 2
-42 > 2 (not true)
d.) x=1, y=5
-5(1)^2 + 20(1) -17 > 5
-2 > 5 (not true)
So, the answer is B.
Answer:
a₆ = 12
Step-by-step explanation:
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₂ = 5 and a₁₀ = 19 , then
a₁ + d = 5 → (1)
a₁ + 9d = 19 → (2)
Subtract (1) from (2) term by term to eliminate a₁
8d = 14 ( divide both sides by 8 )
d = 1.75
Substitute d = 1.75 into (1)
a₁ + 1.75 = 5 ( subtract 1.75 from both sides )
a₁ = 3.25
Then
a₆ = 3.25 + 5(1.75) = 3.25 + 8.75 = 12
