Answer:
P = 328 yards
Step-by-step explanation:
formula is P= 2l + 2w
Given:
set-up fee 5,500
variable fee 1 per CD.
Cost per CD is $5.50
5.50 - 1= 4.50
5,500 / 4.50 = 1,222 CDs Choice A.
1*1,222 = 1,222
1,222 + 5,500 = 6,722
6,722/1,222 = 5.50
0.2 is a rounded off answer while 0.201 is the exact answer that's not rounded off.
X² - 14x + 33 = 0 is in the form ax² + bx + c = 0. We will need this for the second step.
Subtract 33 from both sides
x² - 14x = - 33
Divide the b term by 2 and then square the result. Then add that to both sides.
- 14 / 2 is - 7. (- 7)² = 49. Add that to both sides
x² - 14x + 49 = - 33 + 49
Combine the constants and factor the trinomial
(x - 7)² = 16
Square root both sides
x - 7 = +/- 4
or
x - 7 = - 4 and x - 7 = 4
You have to place a plus-minus statement because (- 4)² and 4² both equal 16.
Now we solve for x in each equation. Add 7 to both sides to isolate our variable.
x = 3 and x = 11
Answer: 
Step-by-step explanation:
g°h indicates that you must plug the function h(x) into the function g(x) as you can see below:
Now you must simplify by adding like terms, as following:
By definition you have that:
Theen you must solve for x:
Therefore, the domain is:
{
∈R:}
Then the answer is
