Answer:
9.3 inches
Step-by-step explanation:
The computation of the radius of the spinner be given below:
Let us assume the same be x
So
We know that
Total area of the sector = one-sixth of the total area of the spinner
Given that
45.1 = 1 ÷ 6 × π × r^2
r^2 = 45.1 × 6 ÷ π
r^2 = 86.1
r = 9.279
= 9.3 inches
9x+72 = 4x+112
5x = 40
x = 8
B. Plug in the numbers and use common sense.
Selection A is appropriate.
_____
The black dot on the graph means that one of the regions of interest will be
x ≤ 1
The y-intercept for the left branch of the graph is -4, so we khow that
y = x³ -4, x ≤ 1
will be part of the function definition.
