Answer: 121.126
<u>Step-by-step explanation:</u>
8.5 3
x <u>1 4.2</u>
1 7 0 6 (2 x 853)
3 4 1 2 0 (40 x 853)
<u>8 5 3 0 0</u> (100 x 853)
12 1 1 2 6
12 1 .1 2 6 (moved the decimal 3 places)
The answer is the product of their slope is -1.
First, let's break this down. Perpendicular lines are line with opposite reciprocal slopes. Opposite meaning the inverse sign and reciprocal meaning flipped.
For instance,
If a line had the slope of 5, its inverse would have a slope of -1/5.
Now, if we multiply these numbers together,
5 * -1/5 = -1
The 5's cancel out.
This works for any two perpendicular lines
It is given in the question that,

Since we have the value of r given, so we have to use the formula to find the nth term of the geometric progression, which is

Substituting the values of a and r, we will get

So the correct option is the third option .
452 because you will multiply 80 by 6 and get 480 and subtract 28 from that!
Answer: C. 70 percent
Step-by-step explanation:
Given, Time for the first unit = 50 minutes
Time for the second unit = 35 minutes
The unit improvement factor learning curve = (The time for the second unit) ÷ (time for the first unit) x 100.
So, The unit improvement factor learning curve = 35÷ 50 × 100 = 70 percent.
Hence, the correct option is "C. 70 percent".
