Answer:
And then the rectangular coordinates for this case are :
Step-by-step explanation:
We have the following point given 
and we want to conver from polar to rectangular coordinates and we need to use the following formulas:
For this case we have that:
And:
Replacing we got:
And then the rectangular coordinates for this case are :
When a line changes position from one point to another, the movement is referred to as transition.
<em>Bobby does not have enough information to make a valid conclusion.</em>
The movements of the lines are given as:
<em>Line 1: 3 units up and 8 units right</em>
<em>Line 2: 8 units down and 3 units right</em>
The given information only describes the movement of both lines, but does not give details about the initial relationship between the lines.
<em>Hence, no valid conclusion can be made with the given information.</em>

Answer:
d. The width of Elly's interval will be less than the width of Drew's interval.
Step-by-step explanation:
The confidence level and the width of the confidence interval are direct proportional. This means that a confidence interval with a higher confidence level has a higher width.
For example, a 99 percent confidence interval is wider than a 90 percent confidence interval.
The midpoint of the confidence interval is the mean of the population, no matter the confidence level.
In this problem, we have that:
Elly: 90 percent CI
Drew: 99 percent CI
The correct answer is:
d. The width of Elly's interval will be less than the width of Drew's interval.

Explanation:
If this is a right triangle we can then substitute the sides of the triangle (12 and 35) and the hypotenuse (37) into the Pythagoras Theorem and the two sides of the equation will be equal. If this is not a right triangle the two sides of the equation will not be equal.
The Pythagoras Theorem is

Answer:
time taken=1800 seconds
Step-by-step explanation:
velocity=v=10m/s
distance=S=18km=18×10³m=18000m
t=?
as we know that
velocity=
velocity×time taken=distance covered
now here we have to find time
time taken=
time taken=
time taken=1800seconds
