What is the greatest measure of length? A. 5,000 meters B. 6,000 centimeters C. 30,000 millimeters D. 1 kilometer
Bess [88]

Answer: A. 5,000 meters

Step-by-step explanation:

Starting with the smallest unit which is option C. There are 10 millimeters in one centimetre. Option c in centimeters is:

= 30,000 / 10

= 3,000 meters.

Option c is smaller than B and so is incorrect.

A meter is 100 centimeters. Option b in meters is;

= 6,000 / 100

= 60 meters

This is less than option A so is incorrect.

A kilometer is 1,000 meters so option A in meters is:

= 5,000 / 1,000

= 5 kilometers

This is higher than option d so option A is correct.

The point L(-4, 2) is reflected over the y-axis. What are the coordinates of the resulting point, L′?
Gre4nikov [31]

Answer:

Point L'(4, 2)

Step-by-step explanation:

To reflect a point is the same as mirroring a point. Since you are reflecting over the y-axis, you would take the opposite of the x coordinate. Hence why it is (4, 2).

Which statement correctly compares the function shown on this graph with the function y = 6x - 1?
charle [14.2K]

Answer:

we conclude that the function shown in the graph has a smaller rate of change and a lower starting point.

Therefore, option (A) is true.

Step-by-step explanation:

<u>FUNCTION</u>

Given the function

y = 6x - 1

Comparing with the slope-intercept form of the graph

y = mx+b

where m is the slope and b is the y-intercept

Thus,

The slope of the function  = rate of change = 6

The starting point of the function can be obtained by setting x = 0 and solve for y

i.e

at x = 0, y = 6x-1 = 6(1)-1 = 5

Thus,

The starting point of the function is (0, 5)

                 

<u>LINE GRAPH</u>

Now, consider the line graph

Taking two points to find the slope

  • (0, -6)
  • (2, 4)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(0,\:-6\right),\:\left(x_2,\:y_2\right)=\left(2,\:4\right)

m=\frac{4-\left(-6\right)}{2-0}

m=5

Thus,

The slope of the line graph  =  rate of change = 5

From the graph, it is clear that at x=0, the value of y=6

Thus,

The starting point of the graph is (0, -6)

Thus,

FOR FUNCTION

The slope of the function  = rate of change = 6

The starting point of the function is (0, 5)

FOR LINE GRAPH

The slope of the line graph  = rate of change = 5

The starting point of the graph is (0, -6)

Conclusion

Hence, we conclude that the function shown in the graph has a smaller rate of change and a lower starting point.

Therefore, option (A) is true.

You are designing a container in the shape of a cylinder. The radius is 5 inches. You want the container to hold at least 725π c
Sav [38]

Answer:

h = 14.5 in

Step-by-step explanation:

Data

radius = 5 in

Volume = 725 π in³

height = ?

Formula

              Volume = 2πr²h

           

Substitution

                    725 π in³ = 2πr² h

                   h = 725π / 2πr²

                   h = 725 / 2(5)²

                   h = 725 / 50

                   h = 14.5 in
