Driving on the highway, you can safely drive 60 miles per hour. "How far can you drive in ‘h' hours?" What is the range of the f

JulijaS [17]

Answer:

D.The distance you drive

Step-by-step explanation:

If you describe this situation as function, then it will look as:

f(h)= 60h
For h=1 you have f(1)= 60 miles
For h=2 you have f(2)= 120 miles etc.

The range of the function is the set of output values

In this case the range is the distance you drive

Correct option is D.

The two triangleshaped gardens are congruent. Find all of the missing side lengths and angle measures. Show any necessary work

pantera1 [17]

The two figures are in the file attached.

Congruency means that all the respcetive sides and angles are equals.

Then, the three angles are :

y = 38°

x = 90°

w = 180° - 90° - 38° = 52

The three sides are:

z= 10yd
v= 7.9yd
u=6.2yd

You have all the measures as a function of yd, but you do not have any information about yd, then it is not possible to find the real lenghts.

All you can tell is that the sides obey Pythagoream theorem:

u^2 + v^2 = z^2

But that is not enough to find one side, because you do not know any of them.

For example if you apply Pytagorean theorem you cand do"

(7.9yd)^2 + (6.2)^2 = (10yd)^2

but that cannot be solved for yd, because they are factors of all the terms in both sides, which mean that they cancel to obtain:

(7.9)^2 + (6.2)^2 = (10)^2, which is not any new information.

Also you can think about sine theorem, but it does not help, because you also need one side.

Then you only can tell the missing angles, as I have shown, but not the misssing lengths.

A book has 12 chapters. The mean length of the chapters is 40 pages. How many total pages are there in the 12 chapters?

amm1812

Answer:

480

Step-by-step explanation:

Important Information:

A Book Has 12 Chapters.

The Mean length of the chapters is 40 pages.

Question to Answer:

How many total pages are there in the 12 chapters?

Explanation/Solution:

Let's assume that the total number of pages in the book is "x" pages.

To find the mean (average) we divide the total "x" by 12 because there are 12 chapters in the book, which would equal to 40.

$\frac{x}{12}$ =40

Multiply both sides by 12...

x = 480

Hence, The total number of pages in the 12 chapters is 480.

Can someone help me?

Tcecarenko [31]

Answer:

The slope is 2

Step-by-step explanation:

Slope formula:

m=(y2-y1)/(x2-x1)

Given:

y2 = -10

y1 = -6

x2 = 2

x1 = 4

Work:

m=(y2-y1)/(x2-x1)

m=(-10 + 6)/(2 - 4)

m= (-4)/(-2)

m = 2

6. Write the equation of the line.

liberstina [14]

Answer:

y = x + 2

Step-by-step explanation:

As the equation of a line is in the form y = mx + c:

Step 1 - Calculate the y intercept

This can be done by looking at the y coordinate where x = 0:

y = mx + c

In the picture, the y intercept is 2 so:

y = mx + 2

Step 2 - Calculate the slope

This can be calculated by:

$\frac{\text{change in y}}{\text{change in x}}$

Get two sets of coordinates:

(0, 2) and (2, 4)

Calculate the changes by subtracting from one another:

$\frac{4 - 2}{2 - 0} \\\frac{2}{2}\\=1$

So the gradient is 1, meaning the equation of the line is:

$y = 1x + 2 \\\text{or}\\y = x + 2$

Hope this helps!
