Jason found a steel wire in a form of a circular ring that had a circumference 25.12 inches. What would be the diameter of the w
2 answers:
<u>Answer:</u>
8 inches
<u>Step-by-step explanation:</u>
The circumference of a circular ring of the steel wire = 25.12 cm
To find the diameter of the circular ring, we will first find the radius of the circular ring, using the circumference, and then multiply it by 2.
We know that:
<em>Circumference = </em>
25.12 = 2 x 3.14 x r
r = 25.12 / (2 x 3.14)
r = 4 inches
Therefore, the diameter of the circular ring will be 2 x 4 = 8 inches.

Answer:
Step-by-step explanation:
In this problem, we are substituting for x.
Let us take a look at our given answers.
x = -13 and x = -3 would not work because the numbers would not add up to -5. Since we have the positive brackets (or whatever you call them.) surrounding the x variable, that means that all numbers that are plugged into x will be positive.
-13 will be turned into 13,
13 - 8 -5
So that is wrong.
x = 3 and x = 3 would work because plugging it in, all outcomes from the two numbers would be negative.
3 - 8 = -5
- 8 = -5
True.
The third one won't work because of the same reasons as the first one.
Then, the last one would not work well because, there is a solution.
Using the interest formulas, it is found that the values of the investment are given as follows:
- Using simple interest, the value will be of $34,000.
- Using compound interest, the value will be of $144,461.
- Using continuous compounding, the value will be of $148,002.
Simple interest is used when there is a single compounding per time period.
The amount of money after t years in is modeled by:
In which:
- P is the initial amount.
- r is the interest rate, as a decimal.
In this problem, we have that the parameters are as follows:
P = 9000, r = 0.07, t = 40.
Hence:
n is the number of compounding, for quarterly n = 4, then:
Hence:
