The total area available for cars to park will be 858m².
<h3>How to calculate the area?</h3>
The area of the parking lot will be:
= 78 × 19
= 1482m²
The area of aisle will be:
= 8 × 78
= 624m²
The available area will be:
= 1482m² - 624m²
= 858m².
The compact parking spaces that will fit in the lot will be:
N × 12.5 = 858
N = 858/12.5
N = 68
The non compact parking spaces that will fit in the lot will be:
N × 16.5 = 858
N = 858/16.5
N = 52

The answer is x^2 + y^2 = 9
For this problem, you should use the equation of circle:
(x - h) ^2 + (y - k)^2 = r^2
where (h,k) is the coordinates of the center
and r is radius
(x - 0) ^2 + (y - 0)^2 = 3^2
Therefore:
x^2 + y^2 = 9
The slope is -11/7

The answer is 1
Use the discramnt formula
Where a is 81, B is 18, and c is 1
We get
We then get 324-324=0
Which equal 0. Since the discramnt produce 0, the number of solution is one and repeated.
