What is the volume of a square pyramids

frozen [14]

Answer:

$\large\boxed{V=75\ in^3}$

Step-by-step explanation:

The formula ogf a volume of a pyramid:

$V=\dfrac{1}{3}BH$

B - area of a base

H - height

We have a base length a = 5 in and a height H = 9 in.

In the base we have a square. The formula of an area of a square is:

$B=a^2$

Substitute:

$B=5^2=25\ in^2$

Calculate the volume:

$V=\dfrac{1}{3}(25)(9)=(25)(3)=75\ in^3$

Which graph represents exponential decay?

xz_007 [3.2K]

Answer:

(d) -- see attached

Step-by-step explanation:

A graph that shows exponential decay is one that tends toward a horizontal asymptote as x gets large.

A basic (parent) exponential decay curve is concave upward and tends toward zero as x gets large. The fractional change in any interval is the same as for any other interval of equal size. The curve attached decreases by a factor of 2 when x increases by 1.
