Assuming the triangle ABC is equal to the triangle QRS means that their sides will have the same size.
So the side AB is the same as QR. As well as  BC is the same size as RS; AC is the same as QS.
So, if AB = QR that means that both have 50 cm.
Answer: 50 cm

A. What is the approximate perimeter of the concrete region?
Nastasia [14]
You have a square with half circles along the sides.
The length of each side is 4ft, so the radius of the circles is 2ft

to calculate the perimeter you can calculate the circumference of 4 half circles = 2 complete circles
c=2r*\pi=
2*2\pi=12.56
perimeter=2c=25.12=8\pi

the area is the area of 2 circles+the area of the square
circle area= r^2*\pi=2*2\pi=4\pi
concrete area=circle area*2+square area
=4\pi *2+(4*4)
=8\pi+(4*4)
=8\pi+16ft
=41.12 ft^2

Answer:

1) The equation for the of the ball in y = a·(x - h)² + k is;

y = -16·(x - 5)² + 25

2) The height of the dock, d =  -375 feet below the water level

Step-by-step explanation:

1) The question is with regards to quadratic function representing projectile motion

The given parameters are;

The height the ball reaches 4 seconds after Sarah kicked the ball = 9 feet

The time the ball hits the water = 6 seconds after reaching the 9 feet height

The form of the quadratic equation representing the motion is given as follows;

y = a·(x - h)² + k = a·x² - 2·a·h·x + a·h² + k

Let 'x' represent the time of motion of the ball, and let 'a', represent the acceleration due to gravity, we have;

The equation for the ball, y = a·(x - h)² + k

Where;

(h, k) = The coordinates of the vertex

h = The horizontal component of the vertex coordinate = 0

Therefore, we have;

When x = 0, y = d

d = -16·(0 - h)² + k =  -16·h² + k

d = -16·h² + k  

When x = 4, y = 9 - d

9 - d = -16(4 - h)² + k = -16(4 - h)² + k

When x = 2, y = d

d = -16(2 - h)² + k

When x = 6, y = 9

9 = -16(6 - 5)² + k

When x = 8, y = d

d = -16(8 - h)² + k

-16(8 - h)² - (-16(2 - h)²) = 0

h = 5

From 9 - d = -16(4 - h)² + k = -16(4 - 4)² + k

d = 9 - k

9 = -16(6 - h)² + k

k = 9 + 16(6 - 5)² = 25

d = 9 - k = 9 - 25 = -16

Therefore, h = 5, k = 25

The equation for the of the ball in y = a·(x - h)² + k is therefore;

y = -16·(x - 5)² + 25

2) When x = 0, y = d, ∴ d = -16(0 - 5)² + 25 = -375 feet below the water

The height of the dock, d =  -375 feet below the water level
