A sprinting cheetah covered a distance of 518 meters in 18.5 seconds. If the cheetah ran a constant speed, how fast was it runni
artcher [175]

Answer:

Speed of the cheetah would be 28 m/sec

Step-by-step explanation:

Given:

Distance covered = 518 meters

Time taken = 18.5 seconds

To Find:

Speed of cheetah = ?

Solution:

We are given with the distance and time of the cheetah and we have to find the speed of the cheetah which we can find out by the formula i.e.

Distance = speed * time

Putting in the values

518 = speed * 18.5

Dividing both sides by 18.5

it gives us

518 / 18.5 = speed                               ∴ 18.5 / 18.5 = 1  and 1* speed = speed

28 m/sec = speed

Or Speed = 28 m/sec

Speed of the cheetah would be 28 m/sec

Describe the transformation required to obtain the graph of the given function from the basic trigonometric graph.
Alik [6]

Answer:

Option d

Step-by-step explanation:

If the graph of the function y=cf(x) +b  represents the transformations made to the graph of y= f(x)  then, by definition:

If  0 then the graph is compressed vertically by a factor c.

If  |c| > 1 then the graph is stretched vertically by a factor c.

If c  then the graph is reflected on the x axis.

If b> 0 the graph moves vertically upwards.

If b the graph moves vertically down

In this problem we have the function y=cscx -9 and our parent function is y = cscx

therefore it is true that c =1  and b =-9 < 0

Therefore the graph of y=cscx is not stretched vertically and is not reflected.  however as b 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>
