what is the range of h

Answer:

12:15 or a quarter past 12

Step-by-step explanation:

Math.

The correct answer is:   " 12:15 a.m."

Step-by-step explanation:

1 hour = 60 minutes {"exact equivalent."}

 ⇒ p.m.  =  afternoon or evening;

 {Note: "p.m." stands for: post meridiem —in Latin terminology.}.

____

7 hours + 5 hours = 12 hours;  12 hours + [tex]\frac{1}{4}[/tex] hours  = 12[tex]\frac{1}{4}[/tex] hours.  

____

1) 1st hour:    7 pm - 8 pm

2) 2nd hour:  8 pm - 9 pm

3) 3rd hour:   9 pm - 10 pm

4) 4th hour:   10 pm - 11 pm

5) 5th hour:  11 pm - 12 am ;

Note:  After 5 [five] hours past 7:00 pm;

The determined time, at this stage of solving this problem, is: 12am ; {commonly known as midnight ; based on the "am/pm" time schedule.

 {Note: "a.m." stands for:  ante meridiem— in Latin terminology.}

Then: we add:  " [tex]\frac{1}{4}[/tex] " hour to: 12 am.
____
[tex]\frac{1}{4}[/tex] hr = 0.25 hr.

{ [tex](\frac{1}{4} hr )* \frac{60minutes}{hr} =?[/tex] } ;

→  The units of "hr" [for: "hour(s)"]; cancel out ; since: "[ (hr ÷ hr) = 1 ] ".

and we have:  [tex]\frac{1}{4}* 60= 60/4 =[/tex] [tex]15 min.[/tex]

____

So:  12am + 15 minutes;  which is: 12:15 a.m. → the correct answer.

Hope this is helpful to you!

the 3 correct statements are:

For a function f(x), we define the inverse function f⁻¹(x):

This means that, if for a given value of x = x₀ we have:

f(x₀) = y₀

Then:

f⁻¹(y₀) = x₀

From this, we can conclude that the domain of f(x) is the range of the inverse, and the range of f(x) is the domain of the inverse.

Answer:

[tex]y=\frac{2}{5}x-3[/tex]

or

[tex]y+3=\frac{2}{5} (x-0)[/tex]

Step-by-step explanation:

We are given two points on Line A: (0,-3) and (5,-1). We can assign each integer to a variable in the slope formula (see above):

[tex]x_1=0[/tex]

[tex]y_1=-3[/tex]

[tex]x_2=5[/tex]

[tex]y_2=-1[/tex]

As we have identified point, we can now work to identify slope by substituting our points into the slope formula:

[tex]m=\frac{-1-(-3)}{5-0}=\frac{2}{5}[/tex]

Now that we have identified both point and slope for Line A, we can format these values in point-slope form. Substitute values into the formula:

[tex]y-(-3)=\frac{2}{5} (x-0)=y+3=\frac{2}{5}x[/tex]

Solve for [tex]y[/tex] to achieve an answer in slope-intercept form ([tex]y=mx+b)[/tex]:

The bucket and the jar together will hold (c + d) litres of water.

A linear equation in 2 variables [x and y] is any equation with the form:

ax + by = c and at least one of a or b being non-zero.

This is known as the equation's General Form.

For the given question;

The water hold by bucket = c litres.

The water hold by jar = d litres.

Thus, the water hold by both bucket and jar is is linear equation with two variable c and d.

Total water =  c + d

By, varying any value the total amount of the water will also get change.

Thus, total water hold by jar and bucket is (c + d) litres.

Considering the expression of a line, they do not have the same value of m. So, the two lines are not parallel.

A linear equation o line can be expressed in the form y = mx + b

where

Knowing two points (x1, y1) and (x2, y2) of a line, the slope m of said line can be calculated using the following expression:

m= (y2 - y1)÷ (x2 - x1)

Substituting the value of the slope m and the value of one of the points in the expression of a linear equation, y = mx + b, the value of the ordinate to the origin b can be obtained.

Parallel lines are two lines that are always at the same distance from each other and that prolonged towards infinity never touch.

Two lines are parallel if they have the same slope and different y-intercepts. That is, they have the same value of m and different value of b.

In this case, you can calculated the slope of the two lines as:

Being (x1,y1)= (-3,2) and (x2,y2)= (4, -1), the slope m can be calculated as:

m= (-1 -2)÷ (4 - (-3))

Solving:

m= (-3)÷ 7

m= -3/7

Being (x1,y1)= (1,3) and (x2,y2)= (-2,-4), the slope m can be calculated as:

m= (-4 -3)÷ (-2 -1)

Solving:

m= (-7)÷ (-3)

m= 7/3

You can observe that they do not have the same value of m. Finally, the two lines are not parallel.

We are told that Lauren is trying to approximate the solution to n² = 115.

Now, she has figured out that it lies between √100 and √121..

Now, √100 = 10 and √121 = 11. Thus, we can say that if she says it is between 4 and 5, then she is wrong because the nearest perfect squares are 10 and 11 which are different from what she got.
