Answer:
.
Step-by-step explanation:
Find two points on the original line, :
Setting gives , which corresponds to the point .
Setting gives , which corresponds to the point .
Reflect the two points with respect to the -axis by inverting the -coordinate of each point. The point stays the same, whereas the point would be mapped to .
Find the equation of the new line. The slope of the new line would be:
.
Equation of the new line in point-slope form:
.

Answer:
- 22
Step-by-step explanation:
A fall of degree = 0.5 degrees is represented as
- 0. 5 degrees
The temperature at 2 : 00 is therefore
- 21.5 - 0.5 = - 22 degrees
Answer:
2.29
Step-by-step explanation:
First determine the square root of 17.8
√17.8 = 4.22
second, determine the value of = 1.93
subtract 1.93 from 4.22
4.22 - 1.93 = 2.29
Answer:
308cm³
Step-by-step explanation:
volume of cylinder = πr²h
volume = (22/7)*(7/2)*(7/2)*8
volume = 308cm³
It tells you how many places you have to move the decimal to right in order to get the proper quotient(answer).
