Use the sin function to solve for the central angle.
Chord length = 2Rsin(c/2)
where
chord length =4.5 feet
radius = 5 feet
C= central angle
Rearrange the formula to get the central angle and substitute all the given values
Central angle = 53.49 degrees
The general form of the linear equation is:
y = mx + c where:
m is the slope and c is the y intercept
We are given that the slope is equal to -2
Therefore, the equation now becomes:
y = -2x + c
To get the value of the c, we will use the given point (0,0) to substitute in the equation and solve for c as follows:
y = -2x + c
0 = -2(0) + c
c = 0
Based on the above calculations, the equation of the line would be:
y = -2x
Answer:
g(7) = 16
Step-by-step explanation:
The domain definitions in this piecewise function tell you that the third (bottom) piece applies when x=7.
g(7) = (7+1)(7-5) = (8)(2)
g(7) = 16
