Answer:

16 m^3

Step-by-step explanation:

Question:

"a regular square pyramid is 3m height and the perimeter of its base is 16m find the volume of the pyramid"

volume of pyramid = (1/3) * (area of base) * height

The perimeter of the base is 16 m, and the base is a square.

perimeter of square = 4 * side

4 * side = 16 m

side = 4 m

area of square = (side)^2

area of base = (4 m)^2 = 16 m^2

volume of pyramid = (1/3) * (area of base) * height

volume = (1/3) * (16 m^2) * 3 m

volume = 16 m^2

A goods train runs at the speed of 72 kmph and crosses a 250 m long platform in 26 seconds. What is the length of the goods trai

Flauer [41]

The length of the goods train is 270 meters.

Given that, a goods train runs at the speed of 72 kmph and crosses a 250 m long platform in 26 seconds.

<h3>What is the distance formula with speed and time?</h3>

Speed is defined as the rate at which an object moves from one place to another in a given interval of time. It is a scalar quantity as it defines only the magnitude not the directions of an object moving. The S.I. unit of speed is m/s.

The speed of a moving object can be calculated as Speed = Distance / Time.

Now, to convert km/h to m/sec multiply the measure by 5/18.

That is, 72 × 5/18 = 20 m/sec

Let the length of the train be x metres.

So, then (x+250) / 26 = 20

⇒x+250=520

⇒x=270 meters

Therefore, the length of the goods train is 270 meters.

In order to find the perimeter of a shape, we should add all of its sides.

Since a triangle has only 3 sides, we add 3 sides together, like so:-

⇒ 9x-7+12x-13+3x+8

Combine like terms:-

➪ 9x+12x+3x-7-13-8

Which simplifies to

➪9x+15x-7-21

On further simplification,

➪24x-28

So we conclude that the perimeter of the triangle is 24x-28 units.

F(x) = x2 + 10<br> What is the average rate of chan<br> hange of f over the interval [-2, -1]?

Readme [11.4K]

The average rate of change is given by [f(b) - f(a)]/(b - a), where a and b represent the interval [a, b].

Let a = -2

Let b = -1

[(-1)^2 + 10 - ((-2)^2 + 10)]/(-1 -(-2))

[1 + 10 - (4 + 10)]/(-1 + 2)

[1 + 10 -4 -10]/(1)

[1 - 4]/(1)

-3/1

Andre : Anything less than -100, for example -150

-150<-100

|-150|=150

Han: Anything between -100 & 100, for example 50

50> 100

|50|= 50
