Plug 3 in for r it equals 28.26 so its A
Hopes this helps:
Answer: x = -10/7
1. Simplify 2 • 2 to 4
4 + 7x + 6 = 0
2. Simplify 4 + 7x + 6 to 7x + 10.
7x + 10 = 0
3. Subtract 10 from both sides.
7x = -10
4. Divide both sides by 7.
X = -10/7
Common ratio, is r=6/3=12/6=2
Answer: common ratio 2
First term a₁ = 3
nth term aₙ = a₁rⁿ⁻¹ = 3 (2ⁿ⁻¹)
13th term = 3(2¹²) = 12288
Answer: 13th term is 12,288
Answer:
f(x) = 9x - 18
Step-by-step explanation:
Moving the graph to the left or right involves directly manipulating the "x" value. When you want to shift the graph to the right, you need to subtract the desired value directly from "x". This would make the equation look like this:
f(x) = 9(x - 2)
However, this can be simplified by multiplying 9 by each term in the parentheses.
f(x) = 9x - 18
Answer:
<u>The variance of the sample data is 134.8339 kg²</u>
Step-by-step explanation:
Let's recall that the Standard deviation of a sample or population is the square root of the Variance, therefore:
Standard deviation = √Variance
Standard deviation² = (√Variance)²
Standard deviation² = Variance
Replacing with the value we have:
11.6118 * 11.6118 = Variance
Variance = 134.8339 kg²
<u>The variance of the sample data is 134.8339 kg²</u>
