Answer:
W = 4.95
Step-by-step explanation:
You want to start by writing down what you know, and forming a system of equations.
L= length W= width
2L+2W=14.7
L= 2.4
On the left side of the equation, you're adding all your side lengths, and on the right, is the total perimeter. (Also could be written L+L+W+W = 14.7)
You would then substitute L from the bottom equation into the top equation to get:
2(2.4) +2W=14.7
Solving:
4.8+2w=14.7
W= 4.95
To check your answer simply add all the sides together and make sure it equals your perimeter. You can also plug W and L back into the original equation.
Answer:
9 feet
Step-by-step explanation:
The height of the ball in feet is given by the polynomial:

where t is the time in seconds.
After 3 seconds, t = 3:

The height of the ball after 3 seconds is 9 feet.
Non-linear
The line should be an exponential function, as it halves in mass every time a certain amount of time has passed.
