Answer:
c. 55.4 ft/s
Step-by-step explanation:
Speed of the object is represented by the function:
where x represents the number of feet the object has fallen. We have to find the speed of the object after it has fallen 48 feet. This means we have to find f(x) for x = 48. Substituting x = 48 in above equation we get:
Thus, rounded to nearest tenth, the speed of the object after it has fallen 48 feet would be 55.4 ft/s

Answer:
C(x) = 7.5k + 2400 is the expense equation.
Step-by-step explanation:
The fixed cost per month = $2,400
Cost of producing each shoe = $7.5
Here, let k be the number of shoes produced per month .
So, the monthly expense
= Fixed Cost + (Number of shoes produced per month x Cost per shoe)
or, C(x) = $2,400 + ( k x $7.5)
or, C(x) = 7.5k + 2400 is the expense equation.
Answer:
(b)The original price of the shoes is $60.
Explanation:
Part A
In this situation:
• 15% is the PERCENT
,
• $9 is the PART
,
• The original price is the WHOLE.
Part B
If 15% is taken off, the customer will save $9.
This means that 15% of the original price = $9.
Let the original price=p
The original price of the shoes is $60.
To graph it is (3,1) , = y
