this is random because it wont let me submit the answer unless I write 20 characters lol
Answer: The function could be y= - 3 cos x
Solution:
One x-intercept is (pi/2,0): We can use a trigonometric function like cosine that has x-intercept (pi/2,0).
The domain of the cosine function is the set of all real numbers.
The maximum value is 3, then the amplitude must be 3: y = 3 cos x
The y-intercept is (0,-3) then it is the functio y = 3 cos x, reflected around the x-axis: y = - 3 cos x
Answer:
$450
Step-by-step explanation:
The area of the square is 40,000 square feet so the square's side length is 20 (√40,000).
The company charges $2.50 per foot, and the perimeter is 80 (20*4), so the cost is $400 ($2.50 * 8).
Add on the $50 installation fee and the total cost is $450 ($400 + $50).
