The answer is:  [D]:  105 km³ .
__________________________________________
The volume of the figure shown in the drawing is:  105 km³ .
_____________________________________________________
Explanation: 
_______________________________
To calculate the following of the figure in the drawing (rectangular prism):
____________________________________________________
Volume (V) = B * h ; B = base area; h = height = 7 km (as shown in picture given).

The base area, "B" .   B = (5 km)*(3 km)=15 km²
(Note: The "base" is a rectangle, with a length of 5 km and width of 3 km (as shown in picture given).  

The area of rectangle  =  length * width = (5 km)*(3 km) = 15 km²
So the volume, "V" of the figure shown in the drawing =
   Base area * height  = (15 km²) * (7km) = 105 km³ ;
                              → which is answer choice: [D]._______________________________________________

A triangle T is bounded (on three sides) by the lines x = 6, y = 0, and y = 3 2 x. A rectangle of width w is inscribed inside T.
Viktor [21]

Answer:

33.85 units^2

Step-by-step explanation:

you must first draw the triangle on the plane using the equations (see

attached file), you will have a right angle triangle with a height of 192 and a base of 6.

then you calculate the angle with the tangent function = 88.21

Then you use the small triangle to find the value of a (see attached file).

Finally, you propose an equation for X to find one of the sides of the triangle, once you have x squared it, and you already have the area,

Answer:

(Down Below)

Step-by-step explanation:

Plug in the value of x in the left column for all the values in the equation. I will do a couple for you.

Since -4 is the value of x, substitute it into the equation for x.

y= -4-5=-9

-1

y=-1-5=-6

0

y=0-5=-5

You can do the rest. You got this! Comment if you need more help!
