Answer:
Assuming that the squares are the same size,
the sum of the perimeter of the five squares =
(20 units × side length of each square in units)
If the squares are different sizes, the sum of the perimeter of the five squares =
(4 units × side length of square 1 in units) + (4 units × side length of square 2 in units) + (4 units × side length of square 3 in units) + (4 units × side length of square 4 units) + (4 units × side length of square 5 in units)
Explanation:
The perimeter of a square is 4 × side length because a square has 4 sides and the perimeter of a figure is the surrounding length of the figure.
Evaluate: int (sin 2x)/sqrt(sin^4x+4 sin^2x-2) dx.
3 pounds would cost $6.75
$4.50/2 = $2.25 per pound
$2.25 x 3 = $6.75
Is there like any image to see how big are the posts?
Answer:
Before coming back up to the surface the maximum depth, Cassidy went was 6.25 ft. below the water surface
Step-by-step explanation:
The height of Cassidy's diving platform above the water = 6 ft.
The equation that models her dive is d = x² - 7·x + 6
Where;
d = Her vertical position or distance from the water surface
x = Here horizontal distance from the platform
At Cassidy's maximum depth, we have;
dd/dx = d(x² - 7·x + 6)/dx = 2·x - 7 = 0
x = 7/2 = 3.5
∴ At Cassidy's maximum depth, x = 3.5 ft.
The maximum depth,
= d(3.5) = 3.5² - 7 × 3.5 + 6 = -6.25
The maximum depth, Cassidy went before coming back up to the surface =
= -6.25 ft = 6.25 ft. below the surface of the water.
