Answer:

B. 17

Step-by-step explanation:

We have been given that Maria is placing a barrier around the edge of a circular path with a diameter of 13 meters.

Since we know that circumference of a circle equals 2\pi r, where,

r= Radius of the circle.

Since we have been given the diameter of the circular path, so let us divide our given diameter by 2 to find radius of our circular path.

\text{Radius of circular path}=\frac{13}{2}=6.5

Let us find the circumference of our circular path.

\text{Circumference of circular path}=2*3.14*6.5

\text{Circumference of circular path}=40.82

Since circumference of circular path is 40.82 meters, so to find the number of pieces of barrier we will divide circumference of circular path by length of each barrier.

\text{Number of barriers used}=\frac{40.82}{2.5}

\text{Number of barriers used}=16.328

As the barrier will be used as a whole piece, therefore, Malia needs 17 pieces of barrier and option B is the correct choice.

Graph a line with a slope of 4 that contains the point (3,0). FOR 100 POINTS PLS
dimulka [17.4K]

Answer:

Hi there!

Recall that slope-intercept form is:

y = mx + b

Where m = slope

In this instance, we are given a slope of 4,

therefore:

y = 4x + b

Substitute in the x and y coordinates of the point given:

0 = 4(3) + b

0 = 12 + b

Substract 12 from both side:

-12 = b

Therefore, the equation would be:

y = 4x - 12

Graph the equation by finding x and y values or using a calculator:

x = 0, y = 4(0) - 12 = 12 (0, 12)

x = 1, y = 4(1) - 12 = - 8 (1, -8)

x = 2, y = 4(2) - 12 = - 4 (2, -4)

x = 3, y = 4(3) - 12 = 0 (3, 0)

And so forth:

Need help with all And have to show work
kari74 [83]
Altho' I can easily guess what you're supposed to do here, I must point out that you haven't included the instructions for this problem.

I'll help you by example.  Let's look at the first problem:

"Evaluate  6(z-1) at z-4."

Due to "order of operations" rules, we must do the work inside the parentheses FIRST.  Replace the z inside (z-1) with "-4".  We obtain

6(-4-1) = 6(-5) = -30 (answer.)

Your turn.  Try the next one.  If it's unclear, as questions.

gavmur [86]

Answer:

x = 5/-8

Step-by-step explanation:

4x = 12x + 5

4x - 12x = 5

-8x = 5

x = 5/-8
