Answer:
domain: -2 < x < 4
range: -∞ < y < 9
Step-by-step explanation:
domain: because the domain is all of the x-values, just look for the furthest one to the left, which is -2, and then look for the one that is furthest to the right, it being 4.
range: because the quadratic function has the two arrows continuing downwards, toward the negative portion of the graph, it would be -∞. Then look for the maximum of the graph, which would be considered the most highest part of the graph, which is seen on the graph as 9.
Step-by-step explanation:
By Exterior Angle Theorem,
81° + b = 117°.
=> b = 117° - 81° = 36°.

Answer:
154
Step-by-step explanation:
The formula for the area is A=πr2
The line labeled 7 is the radium or the R in the formula
Replace 7 with R
A=π7(squared)
square seven
A=49π
pi is approximately 3.14
mutiply 7 by pi
A= 154
Answer:
units
Step-by-step explanation:
The distance formula states that 
.
We then plug in our points and compute.
The * represents multiplication.
