Answer:
12 in
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = h(b₁ + b₂ )
where h is the height and b₁, b₂ the parallel bases
Given h = 6, b₁ = 8 and A = 60 , then
× 6 × (8 + b₂ ) = 60 , that is
3(8 + b₂ ) = 60 ( divide both sides by 3 )
8 + b₂ = 20 ( subtract 8 from both sides )
b₂ = 12
The length of the second base is 12 inches
The value of f(5) is -37
<em><u>Solution:</u></em>
<em><u>Given function is:</u></em>
We have to find the value of f(5)
To find the value of f(5), we have to substitute x is equal to 5 in given function
Plug in x = 5 in f(x)
Thus value of f(5) is -37
Using the fundamental counting theorem, we have that:
The fundamental counting principle states that if there are p ways to do a thing, and q ways to do another thing, and these two things are independent, there are ways to do both things.
For the area code:
Thus:
648 different area codes are possible with this rule.
For the number of 10-digit phone numbers:
Then
There are 6,480,000,000 possible 10-digit phone numbers.
The amount of possible phone numbers is greater than 400,000,000, thus, there are enough possible phone numbers.
