Ray is purchasing a laptop that is on sale for 25% off. he knows the function that represents the sale price of his laptop is c(p) = 0.75p, where p is the original price of the laptop. he also knows he has to pay 8% sale's tax on the laptop. the price of the laptop with tax is f(c) = 1.08c, where c is the sale price of the laptop.
determine the composite function that can be used to calculate the final price of ray's laptop by solving for f[c(p)].
f[c(p)] = 1.83p
f[c(p)] = 1.83cp
f[c(p)] = 0.81p
f[c(p)] = 0.81cp

Step-by-step explanation:

Given: Ray is purchasing a laptop that is on sale for 25% off.

The function that represents the sale price of his laptop is , where p is the original price of the laptop.

The percent of tax on laptop=  8%

The price of the laptop with tax is , where c is the sale price of the laptop.

The composite function that can be used to calculate the final price of Ray's laptop will be:-

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

the answer for this question is 38
