Answer:
Option (B) is correct.
Allison biweekly gross pay is $942.31
Step-by-step explanation:
Given annual salary offered to Allison = $24,500.
We have to calculate Allison biweekly pay that is pay Allison got for 2 weeks
To calculate biweekly we first find Allison weekly pay then multiply it by 2.
We know there are 52 weeks in a year.
So, weekly salary offered to Allison
(approx)
Biweekly salary will be = 2 × weekly salary
= 2 × 471.15
= 942.307(approx)
Thus, Allison biweekly gross pay is $942.31

Answer:
Center: (4,8)
Radius: 2.5
Equation: 
Step-by-step explanation:
It was given that; the endpoints of the longest chord on a circle are (4, 5.5) and (4, 10.5).
Note that the longest chord is the diameter;
The midpoint of the ends of the diameter gives us the center;
Use the midpoint formula;

The center is at; 
To find the radius, use the distance formula to find the distance from the center to one of the endpoints.
The distance formula is;




The equation of the circle in standard form is given by;

We substitute the center and the radius into the formula to get;
