A small restaurant named the Pizza Palace had a food critic try their pizza and wrote them a very, very bad review. The function

I am Lyosha [343]

The statement which describes what the equation tells is; The number of customers they have prior/before the review is; 500 customers.

The number of customers they have 2 months after the review is; 222.22 customers.

<h3>Exponential functions</h3>

According to the given function;

The intercept of the function represents the number of customers the restaurant has prior to the review.

This means the number of customers they have prior/before the review (at m=0) is; 500 customers.

Additionally, after 2 months of the review;

C = 500 × (2/3)^2

C = 500 × 0.44

C = 222.22 customers

Hello!

The figure is made up of a cone and a hemisphere. To the nearest whole number, what is the approximate volume of this figure? Use 3.14 to approximate π . Enter your answer in the box. cm³

A 12 cm cone with a dome on top of it that has an 8 cm diameter

Data: (Cone)

h (height) = 12 cm

r (radius) = 4 cm (The diameter is 8 being twice the radius)

Adopting: $\pi \approx 3.14$

V (volume) = ?

Solving: (Cone volume)

$V = \dfrac{ \pi *r^2*h}{3}$

$V = \dfrac{ 3.14 *4^2*\diagup\!\!\!\!\!12^4}{\diagup\!\!\!\!3}$

$V = 3.14*16*4$

$\boxed{V = 200.96\:cm^3}$

Note: Now, let's find the volume of a hemisphere.

Data: (hemisphere volume)

V (volume) = ?

r (radius) = 4 cm

Adopting: $\pi \approx 3.14$

If: We know that the volume of a sphere is $V = 4* \pi * \dfrac{r^3}{3}$ , but we have a hemisphere, so the formula will be half the volume of the hemisphere $V = \dfrac{1}{2}* 4* \pi * \dfrac{r^3}{3} \to \boxed{V = 2* \pi * \dfrac{r^3}{3}}$
