10 meters per second converts to 36 kilometers per hour. Therefore to find how far the cyclist goes in 3 hours, you multiply that number by 3 to get 108 kilometers.

Compare the slopes of the linear functions f(x) and g(x) and choose the answer that best describes them.
Tcecarenko [31]

Answer:

The slope of f(x) is equal to the slope of g(x).

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

step 1

Find the slope of the function f(x)

we have the points

(0,-1) and (3,1)

substitute in the formula

m=\frac{1+1}{3-0}

m_1=\frac{2}{3}

step 2

Find the slope of the function g(x)

take two points of the given table

(0,2) and (3,4)

substitute in the formula

m=\frac{4-2}{3-0}

m_2=\frac{2}{3}

step 3

Compare the slopes

m_1=m_2

therefore

The slope of f(x) is equal to the slope of g(x).

F(x)2x²+1and g(x)=x²-7find (f+g)(x)
Vilka [71]

Answer:

3x² - 6

Step-by-step explanation:

note that (f + g)(x) = f(x) + g(x), thus

f(x) + g(x)

= 2x² + 1 + x² - 7 ← collect like terms

= 3x² - 6

Georgia has some 4-inch cubes like the one shown below. Georgia will put the cubes in the box shown below.
marishachu [46]

The question is incomplete. The complete question is :

Georgia has some 4-inch cubes like the one shown below. Georgia will put the cubes in the box shown below. What is the total number of cubes that Georgia needs to exactly cover the bottom of the box with a layer one cube deep?

Solution :

It is given that :

There are small cubes that has a dimension of 4 in x  4 in x  4 in.

There is also a box which has a dimension of 24 in x 20 in x 12 in.

We need to find out how many small cubes will Georgia need to cover the bottom of the box.

So, we need to find out the surface area of the one cube and the box.

Therefore, the surface area of one cube = side x side

                                                                   = 4 inch x 4 inch

                                                                   = 16 square inches

Similarly the area of the box can be find by = length x breath

                                                                        = 24 in x 20 in

                                                                           = 480 square inches

Therefore, dividing the area of the box by the area of the cube, we get

$=\frac{480}{16}$

= 30

So Georgia will require exactly 30 cubes to cover the bottom of the box with a layer of one cube deep.
