$490.50 was the original price of the ski set
To solve- you multiply 327 and 0.2 (20%) which equals 65.4
Then you multiple 327 and 0.3 (30%) which equals 98.1
To find the final original price, you add up 65.4,98.1, and 327
Then to double check your answer, you can take 30% and then 20% of the originally price and subtract them from the original price
I hope my answer was clear enough!
Answer:
Step-by-step explanation:
The rocket will hit the ground when y = 0. If you use the quadratic equation:
x = (-248±√(2482-4(-16)(116))/(2(-16))
Option 1. 
is obtained by eliminating the parameter.
Step-by-step explanation:
Step 1:
We have that 
and 
Take as equation 1.
Assume 
is equation 2.
We need to determine a value that is equivalent to t so it can be substituted in equation 2.
Step 2:
If we square equation 1, we get
So we have a value that can replace t, so we substitute this is equation 2.
so
which is the first option.
Answer:
1.68 ft
Step-by-step explanation:
Let x be the radius
Arc length = 3.14x
Width = 2x
Height = [12 - (2x) - 3.14x]/2
= 6 - 2.57x
Area = 3.14x²/2 + 2x(6 - 2.57x)
Area = 12x - 3.57x²
dA/dx = 12 - 7.14x = 0
x = 1.6806722689
Height = 6 - 2.57x
= 1.6806722689
Answer: x has to be less than 5 i can’t read it but it is starting from positive 5 with the arrow going to the left
