Answer:
4%
Step-by-step explanation:
We assume the interest earned is simple interest, because that make the numbers come out "nice."
The account balance is given by ...
A = P(1 +rt) . . . . principal P earns simple interest at annual rate r for t years
1080 = 1000(1 +r·2) . . . . fill in the given values
1.08 = 1 +2r . . . . . . . . . . divide by 1000
0.08 = 2r . . . . . . . . . . . subtract 1
0.04 = r = 4% . . . . . . . divide by 2
The annual interest rate is 4%.
_____
<em>Additional comment</em>
If interest is compounded annually, the annual rate is about 3.92%. If it is compounded continuously, the rate is about 3.85%.
An equation can be set up as: 45,750 = 50x + 800
x representing each installment
We can simplify this by subtracting 800 and dividing by 50:
44,950 = 50x
899 = x
Answer:
B?
Step-by-step explanation:
On this number line there is no seven, but there is everything from 1 to 0.
Step-by-step explanation:
The way i like to remember it is that the exponent inside of the radical will be the numerator of the fraction and the index of the radical will be the denominator so the answer is 2^(-5/3).
For x=5 y=4 so we can calculate the slope m=(y1-y)/(x1-x)=(5-0)/(4-0)=5/4
then use (y-y1)=m(x-x1) and you get
y=(5/4)x-5
