Answer:
the annual interest rate is 7.583%
Step-by-step explanation:
We are given
Summer has an offer to buy an item with a sticker price of $13,200
so, we have
P=13200
paying $460 a month for 36 months
so, we can find total amount
Let's assume
annual interest is r
total time =36 months
so, total number of years =3
Since, it is compounded monthly
so, n=12
now, we can use formula
now, we can plug values
now, we can solve solve for r
So, the annual interest rate is 7.583%
Answer:
y=640-3x
Step-by-step explanation:
The total amount of ounces in the bucket is 640, and it decreases by 3 each minute. For example, if you plug in 3 for x into that equation (which would represent 3 minutes), you would lose 9 ounces of water, which makes sense in the terms of the equation.
Answer:
(x-5)^2+2
Step-by-step explanation:
To convert between standard and vertex form, you have to complete the square (which, as a reminder, (a+b)^2 = a^2+2ab+b^2).
Since a^2 is x^2, and 2ab is -10x, then b must be -5, so b^2 is 25. Therefore, we add and subtract 25 from the expression:
(x-10x+25)+27-25
Then, we can make (x-10x+25) to (x-5)^2:
(x-5)^2+2
Answer:
1/3
Step-by-step explanation:
Slope m = (y2-y1)/(x2-x1)
m = (2 - 3)/(3 - 6) = (-1)/(-3) = 1/3
Answer:
The answer is 29 cm.
Step-by-step explanation:
The side we are looking for is the longest side of the right triangle, called a hypotenuse.
To find it, we first have to square 20, which equals 400. Then, square 21, which equals 441. Next, add 400 and 441 to make 841, then find the square root of 841, which is 29.
I hope this helped! :-)
