Answer:
13 units
Step-by-step explanation:
Points A(-1, -6) and B(-1, 7) both lie on the vertical line x=-1. That means the distance between them is the difference of their y-coordinates:
__
By -Ay = 7 -(-6) = 13
Segment AB is 13 units long.
Here you go, it does have a solution, the answer is two.
Answer:
About $78
Step-by-step explanation:
The company is not complete. The question is to estimate the sales 8 weeks after release. To do that, we will substitute t = 8 into the modeled function s=10√5t+15
s = 10√5(8) + 15
s = 10√40 + 15
s =10(6.32)+15
s = 63.2+15
s = 78.2
Hence the sales after 8weeks is about $78.
Answer:
Option a is right.
Step-by-step explanation:
Parent funciton is

The new graph is

Since there is no change for x, there is no horizontal shift.
BUt since sign is changed there is a reflection on the line y=0 i.e. x axis.
Also new y is -2x^3 , -2 indicates the vertical shrink by scale factor 1/2
Option a is right
i.e. there is a reflection on x axis also there is a compression of scale factor 2 vertically.
Answer:
126
Step-by-step explanation:
9 ÷ 20 = 0.45
