Answer:
$ 50,340.97
Step-by-step explanation:
From the above question, we can deduce that we are to find the Initial amount invested which is also called the Principal.
The formula to find Principal in a compound interest question is:
P = A / (1 + r/n)^nt
Where:
A = Total Amount obtained after invested = $80,000
r = Interest rate = 3.1% = 0.031
n = number of times interest in compounded = Quarterly = 4
t = time in years = 15
P = $80,000/(1 + 0.031/4)^4 × 15
P = $80,000/(1 +0.00775)^60
P = $ 50,340.97
Hence, James would have to invest $50,340.97 today to have $80,000 in 15 years.
Answer:
i think x=90 degrees
Step-by-step explanation:
i think it is a right triangle because if you tilt it to a certain angle you can see
You find the scale factor which is 10/4=2.5
then times that by 6.
2.5×6=15 and take 6 from 15.
15-6=9
x=9
hope it helps :-)
Answer:
Step-by-step explanation:
Perimeter= 2L+2W. If L=3W(three times the width) then 2(3W)+2W=112. Or 6W+2W=112 which is equal to 8W=112. To solve for the width, divide both sides by 8 and find 112/8=14, therefore W=14.
Answer:
A linear function is a function whose graph is a straight line on plotting.
Step-by-step explanation:
The general form of such equations is f(x) =ax+b, where x is dependent variable and y is independent variable.
Moreover, linear equation has one independent variable and one dependent variable.
