2.3 would be 2+(3/10), which we would then use a common denominator of 10 to get 20/10+3/10=23/10. 5.06 would be 5+(6/100). 6/100 can be reduced by a factor of 2 to 3/50, which we would then use a common denominator of 50 to get 250/50+3/50=253/50. As a fraction multiplication problem, this would look as (23/10)(253/50)
Answer:
Option d
Step-by-step explanation:
If the graph of the function
represents the transformations made to the graph of
then, by definition:
If
then the graph is compressed vertically by a factor c.
If
then the graph is stretched vertically by a factor c.
If
then the graph is reflected on the x axis.
If
the graph moves vertically upwards.
If
the graph moves vertically down
In this problem we have the function
and our parent function is ![y = cscx](https://tex.z-dn.net/?f=y%20%3D%20cscx)
therefore it is true that
and ![b =-9 < 0](https://tex.z-dn.net/?f=b%20%3D-9%20%3C%200)
Therefore the graph of
is not stretched vertically and is not reflected. however as
then the graph moves vertically 9 units down. <u><em>Observe the image</em></u>
The answer is <em>"vertical translation down 9 units"</em>

Answer:
3.08 km/h.
Step-by-step explanation:
We know that,
Ali traveled at a speed of s km/h for 2.5 hours.
Let d be the distance and t be the time.
...(1)
On his return journey, he increased his speed by 4 km/h and saved 15 minutes. So, distance is d and times is t-15.
...(2)
From (1) and (2), we get
Put t=40 in (1).
So, t=40 and d=100.
Now,
Total distance = d + d = 100 + 100 = 200
Total time = t + t - 15 = 40 + 40 - 15 = 65
So, the average speed is
Therefore, the average speed is 3.08 km/h.
