Answer:

510 square meters

Step-by-step explanation:

You can divide this figure into a number of 2D shapes which you know how to find the area of.

The two triangular sides of the prism each have areas 12*5/2=30 square meters. The area of the rectangle formed by the smaller leg has area 5*15=75 square meters. The area of the rectangle formed by the larger leg has area 12*15=180 square meters. The area of the rectangle formed by the hypotenuse has area 13*15=195 square meters. Adding all of this together, you get:

30+30+75+180+195=510 square meters. Hope this helps!

Answer:

375 cm2

Step-by-step explanation

The surface area formula for a triangular prism is 2 * (height x base / 2) + length x width1 + length x width2 + length x base, as seen in the figure below:

A triangular prism is a stack of triangles, so the usualy triangle solving rules apply when calculating the area of the bases.

Alex Ar [27]
(7,5)(-4,-1)
slope = (-1-5) / (-4-7) = -6/-11 = 6/11

y - y1 = m(x - x1)
slope(m) = 6/11
(-4,-1)...x1 = -4 and y1 = -1
now we sub...pay close attention to ur signs
y - (-1) = 6/11(x - (-4) ...not done yet...

A horse walks around a circular track while its trainer stands in the center. The trainer is 14 feet from the horse at all times
max2010maxim [7]

The horse traveled 439.6 feet after walking around the track 5 times

<u><em>Solution:</em></u>

Given that, horse walks around a circular track while its trainer stands in the center

The trainer is 14 feet from the horse at all times

Therefore, radius of circular track = 14 feet

The circumference of circle is the distance traveled by horse for 1 lap

<em><u>The circumference of circle is given as:</u></em>

C = 2 \pi r

Where, "r" is the radius and \pi is a constant equal to 3.14

C = 2 \times 3.14 \times 14\\\\C = 87.92

Thus the distance traveled by horse for one time in circular track is 87.92 feet

<em><u>About how far had the horse traveled after walking around the track 5 times? </u></em>

Multiply the circumference by 5

distance = 5 \times 87.92\\\\distance = 439.6

Thus the horse traveled 439.6 feet after walking around the track 5 times

Describe the transformation of g(x) = -f(x) + 6
alukav5142 [94]

Answer:

A

Step-by-step explanation:

the "-" sign simply turns everything upside-down. what was above the x-axis is now below it. and vice versa. hence, a reflection over the x-axis.

the "+6" moves then everything up by 6 units. which is a vertical shift up by 6 units.
