At work, greg makes $14 for every hour that he works. Write a function to represent how many dollars, D, greg has entered from working, then calculate how much money he made after working 5 hours

He made $70 in 5 hours

Step-by-step explanation:

Given

Required

Determine a function to represent the amount he made

Determine the amount made in 5 hours

To determine the function (D), we simply multiply the hourly rate by the number of hours worked (h).

So, we have:

Represent D as a function

Solving (b): Amount in 5 hours

We have that

In this case:

So, we have:

Hence, he made $70 in 5 hours

3 ft

step-by-step explanation:

since the triangle is right use pythagoras' identity to solve for a

the square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

a² + 8² = ( )²

a² + 64 = 73 ( subtract 64 from both sides )

a² = 9 ( take the square root of both sides )

a = = 3

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
