Answer:

d. y+8=2(x-4)

Step-by-step explanation:

There are 2 important parts to this question. First, understanding which slopes are perpendicular. The negative reciprocal of a number will be perpendicular to it. So, since the original slope is -1/2 the new slope should be 2.

Then, remember what the point-slope formula is. The point-slope formula is: y-y_{2}=m(x-x_{2}). So if you plug in the point and slope the new equation looks like, y--8=2(x-4). Then, simplify for the final answer of y+8=2(x-4).

How do I find the volume of this solid shape?
olganol [36]

Answer: 17.28

Step-by-step explanation:

To figure out the volume of this solid you will need to do a multiplication problem. Use the equation *r^2*h

Pi = 3.14

R= 1

H= 5.5

So answer will be 17.28 ( because we round it up!)

Now for cubes you will need to use the equation V=L*W*H

Ann [662]

Answer:

113 \frac{1}{3} Yards

Step-by-step explanation:

solving using  Pythagorean Theorem

a^2+b^2=c^2

100^2+53.33^2 = c^2

10,000+2844.0889=c^2

12844.1=c^2 square root

= 113 \frac{1}{3}

Base on the explanation above we can tell that the length of the diagonal across this field is less than 120 yards.
