We answer the question by substituting 5 to all the x's of the given function,
f(x) = 2x² + 2
Substituting,
f(5) = 2(5²) + 2 = 52
Thus, the f(5) is equal to 52. The answer is letter B.
Answer:
- 20-year fixed-rate at 7.5%
- $106,219.32
Step-by-step explanation:
The shorter the term, the lower the amount of interest.
The lower the interest rate, the lower the amount of interest.
The loan that has both a shorter term and a lower interest rate will cost less in interest.
___
The total of payments for the 30-year loan is 396,232.87.
The total of payments for the 20-year loan is 290,013.55.
The amount saved by taking the shorter loan is the difference of these amounts: $106,219.32.
_____
You can use an amortization formula, spreadsheet, or a financial calculator to compute the payments for each loan. The total repayment amount is the product of the monthly payment and the number of them, 360 for the 30-year loan; 240 for the 20-year loan.
Answer:
53
Step-by-step explanation:
Given: The sum of two digit number is 8
Reversing the digit will get us number 18 less than the original.
Lets take x as tenth digit of our number and y as unit digit of our number.
As given sum of digit is 8
∴ 
∴ 
- equation 1
We also know that reversing the digit will get us number 18 less than the original.
∴ 
Now, lets put the value of y from equation 1
⇒ 
⇒ 
⇒ 
∴ 
Next, substituting the value of x in equation 1
⇒ 
∴ 
∴ The original number is 53, sum of the digit is 8 and if we reverse the digit of the number, we get 35, which is 18 less than the original number.
Answer:
The equation e = 4 h can be used to describe this situation.
Jonah earns $20 to babysit for 5 hours.
Step-by-step explanation:
When Jonah babysits one hour, he earns $7.50.
looking at the graph we see at 1 hour he earns 4 dollars false
The equation e = 4 h can be used to describe this situation.
The slope is 4 so y = 4x e = 4h would also work true
Jonah earns $20 to babysit for 5 hours.
Using our equation from above
e = 4*5 = 20 true
The number of hours Jonah works depends on how much he earns.
This would be false
The dependent variable is on the y axis. The amount he earns depends on how much he works
