Answer:
$557.51
Step-by-step explanation:
A financial calculator tells you the payments are ...
on $80,000 at 4.75%: $417.32
on $20,000 at 7.525%: $140.19
Then the total monthly payment is ...
$417.32 +140.19 = $557.51
_____
You can use the amortization formula to find the payment (A) on principal P at interest rate r for t years to be ...
A = P(r/12)/(1 -(1+r/12)^(-12t))
I find it takes fewer keystrokes to enter the numbers into a financial calculator. Both give the same result.
The function f(x) is a function of the variable x.
To solve the function for x = 30, just plug in 30 for x.
14 - 0.5(30) = -1
f(30) = -1
Answer: y= -1x + 5
Step-by-step explanation:
(-3,8) ( 4,1)
8-1= 7
-3-4 = -7
7/-7 = -1 so the slope is -1 so we will use the formula y=mx+b to find the y-intercept
8= -1(-3) + b
8= 3 + b
-3 -3
b= 5 so the y intercept is 5 now we will write the equation like this y= -1x + 5
31) 27
32) 75
33) 74
34) 90 (because it’s a right angle and adds up to 180)
Answer:
A =62x^2
Step-by-step explanation:
The formula for surface area of a rectangular prism is given by
A=2(wl+hl+hw)
Given a width of 2x and length of 3x and a height of 5x, substitute into the equation
A = 2(2x*3x+ 5x*3x+ 2x*5x)
A = 2(6x^2 + 15x^2 +10x^2)
Combine like terms
A = 2(31x^2)
A =62x^2
