Answer: (-6, 5)
<u>Step-by-step explanation:</u>
Use the Midpoint Formula:
Separate the x's and y's and solve them individually:
So, the k-coordinate is (-6, 5)
If you save $4,500 at an interest rate of 13 percent per year, how much will you have at the end.
1 answer:
Simple Interest is the quickest way to calculate interest. The simple interest on the principal amount of $4,500 for 1 year will be $585.
<h3>What is Simple Interest?</h3>Simple interest is a method to calculate interest it's the easiest way to calculate interest on a principal amount.
Given to us
Principal amount, P = $4,500
Rate Interest, r = 13%
Time period, T = 1
As we know the formula of simple interest simply substitute the values,
Hence, the simple interest on the principal amount of $4,500 for 1 year will be $585.

How do I calculate a circle's circumference?
A circle's diameter is multiplied by to determine its circumference (pi). You can also determine the circumference by multiplying 2radius by pi (=3.14).
Given: theta angle (central) = 7.2°; arc length S = 800 km
This indicates that an 800 km long arc is extending a circle with a 7.2° center angle ( earth in this case).
By definition, "An arc's length is a portion of a circle's diameter."
Therefore, we must first establish what percentage of the circle the specified arc length represents.
360° is a complete circle.
Thus, the fraction equals 7.2°/360°, or 1/50.
As a result, the stated arc length (800km) with a 7.2° central angle is 1/50th of the entire circle.
Thus, the whole circumference is 800 x 50, or 40000 km.
Alternately, you can calculate circumference using the formula below:
360° center angle x arc length as the circumference (theta)
Values substituted: circumference 800 = 360° 7.2°
circumference = 360°, 800°, and 7.2°, or 40000 kilometers
Therefore, the earth is 40000 kilometers around. There is no need to round off because the circumference already contains significant figures.
