Answer:

225 m³ or 225 cubic meters

Step-by-step explanation:

Actually it has 5 sides, the 2 bases, the 3 lateral faces.

The formula for the volume of a triangular prism is: $\frac{h*b*l}{2}$

Using the given measurements, we get:

$\frac{9*5*10}{2} =\\\\\frac{450}{2} =\\\\225$

The volume of the prism is 225 m³

joja [24]

25 feet = 25 x 12 = 300 inches

First light is at 16 inches.
300 - 16 = 284 inches

Find the rest of the bulbs:
284 ÷ 4 = 71

Total number of lights = 71 + 1 = 72

A scuba diver dove from the surface of the ocean to an elevation of −49 9/10 feet at a rate of −9.5 feet per minute. After spend

laila [671]

Answer:

Rate of change = 4,06 f/min

Step-by-step explanation:

The ascendent length 28 9/10 = 289/ 10

The time for that ascendent maneuver is total time 17 1/8 minutes - spended time in the elevation 10 minutes, then

17 1/8 = 137/8

137/8 - 10 = ( 137 - 80 ) /8 = 57/8 minutes

The rate of change in the diver´s elevation is

289 / 10 / 57/8

Rate of change = 289*8/ 57*10

Rate of change = 2312 / 570 ft/min

Rate of change = 4,06 f/min

What are the potential solutions of In(x^2-25)=0?

Maslowich

Answer:

$x =\pm \sqrt{26}$

Step-by-step explanation:

Given :-

ln ( x² - 25 ) = 0

And we need to find the potential solutions of it. The given equation is the logarithm of x² - 25 to the base e . e is Euler's Number here. So it can be written as ,

Equation :-

$\implies log_e {(x^2-25)}= 0$
