The answer is 21 which comes from 7 * 3.
Draw the four points in a complex plane. From the drawing you can see that the lenght is 4i - (-3i) = 4i + 3i = 7i, and the width is 1 - (-2) = 1 + 2 = 3.
So, the area is 7 * 3 = 21.
Answer: -11 meters
Step-by-step explanation:
so for the waters surface, we are going to call that 0. if bob is at 15 meters below 0, then -15+4=-11, so he would be at-11 meters in relation to the waters surface.
Answer:
The coefficient of correlation does not change.
Step-by-step explanation:
We are given the following in the question:
The daily intake food is measured in ounces.
The body weight is measured in pounds.
Correlation between food intake and body weight = 0.80
Properties of correlation:
- Correlation is a technique that help us to find or define a relationship between two variables.
- It is a measure of linear relationship between two quantities.
- The correlation between two variables is not effected by the units of the variable.
- Even if the variable of the explanatory variable or the response variable changes, the correlation does not not change and remains same.
Conclusion:
A shift in units from ounces to grams and from pounds to kilogram does not change the value of coefficient of correlation.

Answer:
aₙ=(-2)ⁿ*2.
Step-by-step explanation:
1) -4*(-2)=8; 8*(-2)=-16; -16*(-2)=32, ...
2) the required equation is:
aₙ=(-1)ⁿ*2ⁿ*2; ⇒ aₙ=(-2)ⁿ*2 or aₙ=(-1)ⁿ*2ⁿ⁺¹.
