What is the coordinate of the center in the given equation? (x − 4)2 + y2 = 90

 (4,0)

Explanation:

The given equation is the same as (x-4)^2 + (y-0)^2 = (sqrt(90))^2

It is in the form (x-h)^2 + (y-k)^2 = r^2

We have the following

The center is (h,k) = (4,0) and the radius is sqrt(90) units

6 meters

step-by-step explanation:

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
