Answer:
The length of rectangle is 7 cm and width is 2 cm.
Step-by-step explanation:
Given that:
Area of rectangle = 14 square centimeters
The length of a rectangle is 3 centimeters less than five times its width.
Let,
L be the length and W be the width of the rectangle.
L = 5W - 3
Area of rectangle = Length * Width
14 = (5W-3)*W

Factorizing the equation;

Either,
5W+7 = 0
5W = -7
W = -7/5
Or,
W-2 = 0
W=2
As width of rectangle cannot be negative, therefore,
Width = 2 centimeters
Length = 5(2) -3 = 10-3 = 7
Hence,
The length of rectangle is 7 cm and width is 2 cm.
Answer:
The height of the ball is at it's maximum 1.5 units of time after launch.
Step-by-step explanation:
Suppose we have a quadratic function in the following format:

If t is negative, the maximu value of h(t) will happen at the point

In this question:

So

Then

The height of the ball is at it's maximum 1.5 units of time after launch.
Answer:
$480
Step-by-step explanation:
So first, you find how much he paid per hour which would be 80 * 5 = $400. Then, you have to add the tip in so you do $400 * 1.2 (or 120%) = $480.
The answer to the question
The answer is 76.2cm
