No, the functions shown are not inverses because the inverse for f(n)=-(n+1)^3would be f^−1(n)=−3√n−1.
Answer:
The sector given in the figure is a semi-circle because the degree measure of the chord is 180 degrees.
Area of semicircle = 0.5π
= 0.5π×4.5 = 6.75 sq. inches
Answer:
Y=1/2x +5
Step-by-step explanation:
(0,5) (-10,0)
0-5/-10-0=1/2
(0,5) (x, y)
Y-5/x-10=1/2(crossmultiply)
2y-10=x
2y= x +10(divide all sides by 2)
Y=1/2x+5
Answer:
f(3)=11
Step-by-step explanation:
f(x) = 2x + 5
to find f(3) we simply plug in 3 where ever x is
So f(3) = 2(3) + 5
==> multiply 2 and 3
f(3) = 6 + 5
==> add 6 and 6
f(3) = 11
It has to be 24.
Because 8 is not divisible by 3 or 6 it must be a multiply of two of the numbers. 3*6=18 but 8 is not divisible by that. 3*8 = 24. 24 is divisible by 3 (8), 6 (4), and 8 (3). So 24 is the answer.
