The inverse of a function occurs when _____.

stira [4]

Answer:

⇒When the funtion is both one one and onto , then inverse of the function exists.

⇒≡Consider the function

y=x+2

It is one-one, because for every x there is unique y.So, it is one one.In one-one, there may be some elements in x, which do not have preimage.

It is onto also, because for each x, there is unique y.

So, the inverse of function will be

x=y-2

Replacing x by y and y by x , gives inverse of the function.

y=x-2, is the inverse of the function.

A jet travels 584 miles in 4 hours. At this rate how far could the jet fly in 13 hours?what is the rate of speed of the jet

ankoles [38]

Answer:

The speed at which jet travel is 44.92 miles per hour

The distance cover at 44.92 mph is 583.96 miles .

Step-by-step explanation:

Given as :

The distance cover by jet = d = 584 miles

The time taken b the jet to cover 584 miles = t = 13 hours

Let The speed at which jet travel = s

So, Speed = $\dfrac{\textrm distance}{\textrm time}$

or, s = $\dfrac{\textrm d}{\textrm t}$

Or, s = $\frac{584}{13}$

∴ s = 44.92 mph

So , The speed at which jet travel = s = 44.92 miles per hour

Now, At The speed of 44.92 mph

Let The distance cover at this speed = d' miles

And for the distance of d' , the time taken= 13 hours

Now, Distance = Speed × Time

So, d' = 44.92 mph × 13

Or, d' = 583.96 miles

So, the distance cover at 44.92 mph = d' = 583.96 miles

Hence The speed at which jet travel is 44.92 miles per hour

And The distance cover at 44.92 mph is 583.96 miles . Answer

What is the midpoint between (1,5) and (7,-3)

Leokris [45]

Answer:

(4,1)

Step-by-step explanation:

$Midpoint=(\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})\\$

$=(\frac{1+7}{2},\frac{5-3}{2})\\\\=(\frac{8}{2},\frac{2}{2})\\\\=(4,1)$

The scatter plot shows the relationship between the test scores of a group of students and the number of hours they exercise in

Ira Lisetskai [31]

For part A, the majority of dots circled are what's called a cluster. The one point out by itself is called an outlier. As for part B, it seems that as the hours of computer games played go down, their test scores go up.
