What is the area of cross-section ADGF of this right rectangular prism?

dedylja [7]

Answer:

C.52 square units

Step-by-step explanation:

We are given that

Length of cross-section ADGF,l=13units

Length of cross-section ADGF, b=4 units

We have to find the area of cross-section ADGF of this right rectangular prism.

We know that

Area of rectangle= $l\times b$

Using the formula

Area of cross-section ADGF of this right rectangular prism

= $13\times 4$

Area of cross-section ADGF of this right rectangular prism=52square units

Option C is correct.

C.52 square units

Segment AB is on the line y − 4 = −5(x − 1), and segment CD is on the line y − 4 = one fifth(x − 5). Which statement proves the

Genrish500 [490]

Answer:

Segments AB and CD are perpendicular to each other.

Step-by-step explanation:

If you were to convert line segments AB and CD into slope-intercept form(y=mx+b), you would get y=-5x+1 for AB and y=1/5x-5.

Any line with a slope that is flipped-oppisite (-5/1 to -1/5 to1/5)

of another line must be perpendicular to each other. It doesn't have to have the same y-intercept, it just makes the intersecting point different.

Question 4

sleet_krkn [62]

Answer:

$\displaystyle about\:8\:units$

Step-by-step explanation:

Use the Distance Formula:

$\displaystyle \sqrt{[-x_1 + x_2]^2 + [-y_1 + y_2]^2} = D \\ \\ \sqrt{[6 - 1]^2 + [-7 + 1]^2} = \sqrt{5^2 + [-6]^2} = \sqrt{25 + 36} = \sqrt{61} ≈ 7,810249676 ≈ 8$

Since we are talking about distance, we ONLY want the NON-NEGATIVE root.

I am joyous to assist you anytime.
