Answer:
The value of f(3)=12.4
Step-by-step explanation:
Average rate of change = 3.4
Interval: -2 < x < 3
f(-2) = 9
We need to find f(3)
The formula used to calculate Average rate of change is: 
here we have a=-2 and b=3
Now finding f(3)
So, The value of f(3)=12.4

Answer:
22 boxes were lost. Look for the happy squirrels.
Step-by-step explanation:
Let x be the number of lost boxes. David Express should expect to receive $25 for each of the 325 boxes of apples. That means:
($25)*(325) = $8125
The loss of a box means that the delivery fee would be forfeited, which would amount to: x*($25)
But a compensation fee of $75/box also applies, so the total loss to the income would be x*($25+$75) or x*($100). This would be subtracted from the total expected income of $8125:
Resulting Income: $8125 - ($100)x = $5925
$8125 - ($100)x = $5925
$8125 - ($100)x = $5925
-100x = -2200
x = 22 boxes were lost. Zounds! [A metric term for %$%^&]
===================
<u>Check:</u> Does the loss of 22 of the 325 boxes result in a total payment of $5925?
Delivered boxes: (325 - 22) = 303 boxes delivered. 303*$25 = $7575
Penalty of $75 per lost box: 22*($75) = $1650
Result: $7575 - $1650 = $5925 <u>YES</u>

Answer:
Jaya can afford to rent a car 4 days while staying within her budget.
Step-by-step explanation:
The inequality would have to indicate that the cost of renting a car has to be less than or equal to $230. The cost to rent a car is equal to the cost per day for the number of days plus the price per mile for the number of miles, which is:
53.75x+0.12y≤230, where:
x is the number of days the car is rented
y is the number of miles driven
As the statement says that she plans to drive 125 miles, you can replace "y" with this value and solve for x:
53.75x+0.12(125)≤230
53.75x+15≤230
53.75x≤230-15
53.75x≤215
x≤215/53.75
x≤4
According to this, the answer is that Jaya can afford to rent a car 4 days while staying within her budget.
