What is the area of a rectangle with a length of (x - 5) and width of (x + 8)?
Answers
Answer:
a = x² + 3x - 40
Step-by-step explanation:
a = l * w
a = (x - 5)(x + 8)
a = x(x + 8) - 5(x + 8)
a = (x² + 8x) + (- 5x - 40)
a = x² + 3x - 40

Geraldine invests $2,500 in a retirement account with a fixed annual interest rate of 9.5% compounded
every month. What will the account balance be after 15 years?
Answers
Answer:
FV= $10,342.64
Step-by-step explanation:
Giving the following information:
Initial Investment (PV)= $2,500
Interest rate (i)= 0.095/12= 0.00792
Number of periods (n)= 15*12= 180
To calculate the future value (FV), we need to use the following formula:
FV= PV*(1 + i)^n
FV= 2,500*(1.00792^180)
FV= $10,342.64

Suppose that a regression line for some data transformed with logarithms predicts that when x equals 7. logi) will equal 1.755. What does the regression line predict y will equal when xequals 7? Round your answer to the nearest whole number A. 57 O OB. 12 Oc. 2 O D. 30
Answers
Answer:
A: 57
Step-by-step explanation:
We are told that;
When x = 7, log y = 1.755
Since we want to find the value of y when x = 7, and the log function is in base 10, we will just use anti log to solve for y in the equation.
Thus;
Log₁₀y = 1.755
y = 10^(1.755)
y = 56.89
Approximating to a whole number gives;
y = 57

Convert vertex form f(x)=(x+2)^2-25 to factored form.
Answers
Answer:
f(x)=x^2+4x-21
Step-by-step explanation:
Answer:
f(x) = (x + 7) (x - 3)
Step-by-step explanation:
f(x)=(x+[tex]2)^{2}[/tex]-25
(x + 7) (x - 3) we put the 2 x's because of the (x+2)^2
now the + 7 and - 3, multiply the 2 numbers = -21 then use those 2 in
(x+2)^2 to add for the answer = -25

stay safe healthy and happy..Michelle and Pierre both want to buy guitars, Michelle has already saved $60, and
plans to save $5 per week until she can buy the guitar, Pierre has $25, and plans to save
$12 per week. How many weeks will pass before Michelle and Pierre have the same
amount of money?
Answers
Answer:
on the 5th week they would both have the same amount of money they would both have a total of 85$
Step-by-step explanation:
The number of weeks will pass before Michelle and Pierre have the same amount of money will be 5.
What is the solution of the equation?The solution of the equation means the value of the unknown or variable.
Let x be the number of the weeks and y be the total amount.
Michelle and Pierre both want to buy guitars, Michelle has already saved $60, and plans to save $5 per week until she can buy the guitar, Pierre has $25, and plans to save $12 per week.
Then the equations will be
y = 5x + 60 ....1
y = 12x + 25 ....2
Subtract equation 1 from equation 2. Then we have
7x – 35 = 0
7x = 35
x = 5 weeks
Then the number of weeks will pass before Michelle and Pierre have the same amount of money will be 5.
