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:
See below in exact form
or
2.42, -12.42 to the nearest hundredth.
Step-by-step explanation:
x^2 + 10x - 13 = 17
(x + 5)^2 - 25 - 13 = 17
(x + 5)^2 = 17 + 38 = 55
x + 5 = +/- √55
x = -5 + √55, -5 - √55.
Answer:
First, remember that a circle of radius R centered in the point (a, b) can be written as:
(x - a)^2 + (y - b)^2 = R^2
Suppose that we can model the yard as a rectangular coordinate axis.
And the tree is planted in the point (a, b)
If we want to have 15 feet in all directions around the base of the tree (15 ft around the point (a, b))
The section that must remain unplanted is:
(x - a)^2 + (y - b)^2 ≤ R^2
Where the ≤ symbol is used because all the interior of the circle must remain unplanted (border included)
