I could be wrong but I’m pretty sure x≈102.2 and y≈58
The area of the sports field is 10150 square meters and the length of one lap of the track is 400 meters.
<h3>What is the area of the rectangle?</h3>
It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
Area of the sports field = area of the rectangle + area of the two semicircle
Area of the sports field = 90×70 + π(70/2)²
= 6300 + (22/7)1225
= 6300 + 3850
= 10150 square meters
Length of the track = perimeter of the rectangle + circumference of the
two-semi circle
= 90 + 90 + 2π(70/2)
= 180 + 70(22/7)
= 180 + 220
= 400 meters
Thus, the area of the sports field is 10150 square meters and the length of one lap of the track is 400 meters.

Answer:
<h2>y = -6x - 9</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>y = mx + b</em>
m - slope
b - y-intercept
Parallel lines have the same slope.
===========================================
We have y= -6x - 9 → m = -6
Put the value of a slope and the coordinates of the point (-2, 3) to the equation of a line:
3 = -6(-2) + b
3 = 12 + b <em>subtract 12 from both sides</em>
-9 = b → b = -9
Finally:
y = -6x - 9
Answer:
a) The independent variable is r, the radius. You can use any allowable number for r. The dependent variable is V, the volume. Once you choose a value for r, the value of V will depend on that value of r.
b) The domain is all real numbers greater than 0. A radius cannot be zero or a negative number.
c) The output of V(8) is the function V(r) evaluated at r = 8, so it is the volume of a sphere of radius 8 units.
