Answer:
The first plan of $49 will be best plan for her.
Step-by-step explanation:
Katherine used 1479 minutes call in the last 6 months.
So, the average monthly call that Katherine made is
minutes.
Now, there are two plans for mobile recharge.
One is 250 minutes call time for $49 and the other is 350 minutes call time for $65.
Since 246.5 < 250 and Katherine does not want to spend more for minutes she won't use, then the first plan of $49 will be the best plan for her. (Answer)
Answer:
c = 3√5 ≈ 6.708
Step-by-step explanation:
Use the Pythagorean Theorem because this is a right triangle.
a^2 + b^2 = c^2
3^2 + 6^2 = c^2
9 + 36 = c^2
45 = c^2
√45 = c
<u>c = 3√5 ≈ 6.708</u>
The value of the composite function is (f/g)(5)= 26
<h3>How to evaluate the
composite function?</h3>
The functions are given as:
f(x) = x^2+1 and g(x) = x-4
To calculate the composite function, we use the following formula
(f/g)(x)= f(x)/g(x)
So, we have:
(f/g)(5)= f(5)/g(5)
Calculate f(5) and g(5)
f(5) = 5^2+1 and g(5) = 5-4
This gives
f(5) = 26 and g(5) = 1
Substitute f(5) = 26 and g(5) = 1 in (f/g)(5)= f(5)/g(5)
(f/g)(5)= 26/1
Evaluate
(f/g)(5)= 26
Hence, the value of the composite function is (f/g)(5)= 26

Given
Erin Lytle's gross pay is $26,300
She takes a married exemption of $4,000
state income tax rate is 5.5%
Find out she pay in state income tax
To proof
Gross pay = $26,300
married exemption = $4,000
Let the she pay in state income tax = x
5.5 % written in the simpler form
= 
= 0 .055
than the equation becomes
x = 0.055 ( 26300 - 4000)
x = 0.055× 22300
x = $1226.5
Erin Lytle pay in state income tax is $ 1226.5
Hence proved
