Answer:
no
Step-by-step explanation:
1. to make up the equations of lines PQ and RS:
(PQ)
(RS)
2. to write the pointed verctors of PQ and RS:
for PQ it is p=(2;1); for RS it is r=(-2;1).
3. according to the pointed vectors it is clear, the given lines are not perpendicular <u>[2*(-2)+1*1≠0]</u>.
If there is no decimal you put it behind the last number, so it would be 47.68
Answer:
0.5
Step-by-step explanation:
The given ordered pairs are: (1,2) (2,2.5) (3,3) (4,3.5) (5,4)
The corresponding sequence is :
2,2.5,3,3.5, 4,....
We can see that there is a common difference of d=0.5.
Better still we could use the slope formula:
We substitute the point (1,2) and (2,2.5).
The rate of change of this sequence is:
Answer:
a)2*2*2*2*2*2*2*2*2
Step-by-step explanation:
it wouldn't be done 2*9 but exactly how it is written like
2 by the power of 9
