Answer:
8
Step-by-step explanation:
we know that
The rate of change of a linear equation is a constant that is the same that the slope
step 1
we have
The equation of the graph (function 1) is equal to
y=4
Is a horizontal line
The slope is equal to zero
so
The rate of change of function 1 is zero
step 2
The equation of the function 2 is
This is a linear equation in slope intercept form
where
the slope is equal to m=8
so
The rate of change of function 2 is 8
therefore
The rate of change of function 2 is 8 more than the rate of change of function 1
The probability of hitting the third ring is the same as finding what percentage is the area of the third ring out of the total area of the board.
The area of the third ring = The total area of the board - The area of the second circle.
Refer to the diagram below
The diameter for the whole circle = 32 in
The radius = 16 in
The area of the whole circle = π(16)² = 256π
The diameter for the second circle = 22 in
The radius = 11 in
The area of the second circle = π(11)² = 121π
The area of the third ring = 256π - 121π = 135π
Area of the third ring as a percentage of the total area =
= 52.7%
The area of the third ring = The total area of the board - The area of the second circle.
Refer to the diagram below
The diameter for the whole circle = 32 in
The radius = 16 in
The area of the whole circle = π(16)² = 256π
The diameter for the second circle = 22 in
The radius = 11 in
The area of the second circle = π(11)² = 121π
The area of the third ring = 256π - 121π = 135π
Area of the third ring as a percentage of the total area =
