Answer:
Ronnie spent 5 hours working.
Step-by-step explanation:
From the information given, the total cost of the job is equal to the flat fee plus the result of multiplying the cost per hour for the number of hours which is:
c=25+30x, where:
c is the total cost of the job
x is the number of hours
Now, you can replace c with 175 and solve for x:
175=25+30x
175-25=30x
150=30x
x=150/30
x=5
According to this, the answer is that Ronnie spent 5 hours working.
The answer is the fourth option - <span>f(1) = 4 and f(n) = f(n − 1) + 2; n > 1
</span>
The first term is 4, So, f(1) = 4
The difference between two consecutive integer = 2, so, n = (n-1) + 2
It would be Option D) f(1) = 4 and f(n) = f(n − 1) + 2; n > 1

There is no greatest perimeter of a rectangle with an area of 39 square feet.
To see why, consider the length of 3 and width of 13. Area would be 39 and perimeter would be 3 + 3 + 13 + 13 = 32
Now consider length of 3/2 = 1.5 and 13·2 = 26. Then area is same but perimeter is 1.5 + 1.5 + 26 + 26 = 55.
Now we can just repeatedly half the length and double the width.
L = 3.0, W = 13
⇒ A = 39, P = 32.0
L = 1.5, W = 26
⇒ A = 39, P = 55.0
L = 0.75, W = 52
⇒ A = 39, P = 105.5
L = 0.375, W = 104
⇒ A = 39, P = 208.75
L = 0.1875, W = 208
⇒ A = 39, P = 416.375
L = 0.09375, W = 416
⇒ A = 39, P = 832.1875
L = 0.046875, W = 832
⇒ A = 39, P = 1664.09375
L = 0.0234375, W = 1664
⇒ A = 39, P = 3328.046875
L = 0.01171875, W = 3328
⇒ A = 39, P = 6656.0234375
L = 0.005859375, W = 6656
⇒ A = 39, P = 13312.01171875
Notice how P just kept growing. That's because width grow much faster than length <span>shrinking, </span>so P would grow endlessly.
Hope this helps.
Answer:
option D
Step-by-step explanation:
f(x) = 7x- 3
g(x) = x2 - 4x- 8
we have
(f+g)(x)= 7x- 3 +x2 - 4x- 8
(f+g)(x)= x2+ 3x- 11
