Answer:
Rotation 90° counterclockwise about the origin
Answer:
7 km
Step-by-step explanation:
Substitute:
The equation for area of a semi-circle is 
A =
76.97 =
Multiply by 2 on both sides:
2(76.97) = ( )2
153.94 = 
Divide by pi on both sides:
153.94 =
/pi /pi
49.03 ≈ 
Find the square root:
7 = r
Step-by-step explanation:
Since f(0) = f(5) = f(8) = 0, we have f(x) = Ax(x - 5)(x - 8), where A is a real constant.
We know that f(10) = 17.
=> A(10)(10 - 5)(10 - 8) = 17
=> A(10)(5)(2) = 17
=> 100A = 17, A = 0.17.
Hence the answer is f(x) = 0.17x(x - 5)(x - 8).
Answer:
200
Step-by-step explanation:
Assuming all of the pie chart sections are equal.
There are 5 equal sections so divide the 1000 spins by 5 and you get 200
