Step-by-step explanation:
find the value of f(-4) first
f(-4) = (-4)^2 - 7 ➡ 9 use this to find g(f(-4))
g(9) = 5 - 9^2 ➡ -76
The temperature dropped 5.8 degrees an hour.
Automobile insurance: 809.50
comprehensive coverage: 64
Based on the note:
subtract 64: 809.50 - 64 = 745.50
multiply by 150% : 745.50 x 1.5 = 1,118.25
add 64: 1,118.25 + 64 = 1,182.25
The new total is 1,182.25
To convert degrees to radians multiply degrees by pi/180.
So 90 degrees = 90pi/180 = pi/2 radians or 1.57 radians to the nearest hundredth.
