Find the volume of a pyramid with a square base, where the side length of the base is 4.8\text{ cm}4.8 cm and the height of the

vekshin1

Answer: 35.328 cubic inches.

Step-by-step explanation:

Volume of square pyramid = $\dfrac{a^2}{3}h$ , where a = length of base , h = height

Given: For a square pyramid

a= 4.8 cm and h = 4.6

Then, Volume = $\dfrac{4.8^2}{3}\times4.6$

$=\dfrac{23.04}{3}\times4.6\\\\=35.328\text{ cubic cm}$

Hence, the volume of a pyramid with a square base = 35.328 cubic inches.

Which function is graphed below?<br> y=j3)

natita [175]

Answer:

$y = 3(\frac{1}{3} )^{x}$

Step-by-step explanation:

See the attached graph.

The points (0,3) and (1,1) are on the graph of the exponential function.

Let the function be $y = a(b)^{x}$ ....... (1)

Now, satisfying the point (0,3) we get from the equation (1),

$3 = a(b)^{0} = a$

Therefore, the initial value of the function is a = 3

Hence, the equation becomes $y = 3(b)^{x}$ ......... (2)

Now, satisfying the point (1,1) we get from equation (2)

$1 = 3 (b)^{1}$

⇒ b = 1/3

So, the final equation becomes $y = 3(\frac{1}{3} )^{x}$ (Answer)
