Answer:

28 ft

Step-by-step explanation:

The height of the triangle = 15 ft

The least required area A = 210 ft^2

We know that the area of a triangle = 1/2bh

Where

b is the base

h is the height

Substituting, we have

210 = 1/2 x b x 15

210 = 15/2 x b

420/15 = b

b = 28 ft

Which gives the correct values for points A, B, C, and D?
saveliy_v [14]

Answer:

<em>The correct answer is: A</em>

Step-by-step explanation:

<u>Points on a Numeric Line</u>

The numeric line shown in the figure has four points A, B, C, and D. It's clear that each marked division of the line has a value of 1/4 units and all four points are below the reference zero, thus all are negative.

Point A is clearly on the -2 mark, thus

A=-2

Point B is one mark above A, thus it's located at:

B=-2+\frac{1}{4}=-\frac{7}{4}=-1\frac{3}{4}

B=-1\frac{3}{4}

Point C is one mark below -1, thus:

C=-1-\frac{1}{4}=-1\frac{1}{4}

Finally, point D is one mark below 0:

D=-\frac{1}{4}

The correct answer is: A

Which function does this graph represent: y=x-4;<br> y=-x+4;y=4x-1;y=-4x+1
allochka39001 [22]

The graph represents y=-4x-1

If you notice the line, it goes past the -1 on the y axis which indicates that the y intercept is -1 since that was the only choice which displayed this, we know that our answer is y=-4x-1
