A family purchases a light sphere to be used out on their patio. The diameter of the sphere is 20 in.

NeX [460]

Answer:

Volume of the sphere is 41866.67 in³ .

Step-by-step explanation:

Formula

$Volume\ of\ a\ sphere = \frac{4}{3}\pi\ r^{3}$

Where r is the radius of the sphere .

As given

The diameter of the sphere is 20 in.

$Radius = \frac{Diameter}{2}$

$Radius = \frac{20}{2}$

Radius = 10 in

$\pi = 3.14$

Putting all the values in the formula

$Volume\ of\ a\ sphere = \frac{4\times 3.14\times 10\times 10\times 10}{3}$

$Volume\ of\ a\ sphere = \frac{4\times 314\times 10\times 10\times 10}{3\times 10}$

$Volume\ of\ a\ sphere = \frac{4\times 314\times 10\times 10}{3}$

$Volume\ of\ a\ sphere = \frac{125600}{3}$

Volume of a sphere = 41866.67 in³ (Approx)

Therefore the volume of the sphere is 41866.67 in³ .

The formula A=23.1 е⁰⁰¹⁵²⁺ models the pollution of US state, a, in millions ,t years after 2000.

devlian [24]

The population of the state in 2000 was 23.1 million and the population will be 28.3 million after 13.4 years.

<h3>What is an exponential function?</h3>

The definition of an exponential function is given by the equation

y = aeᵇˣ, where bx is an exponent.

The given equation is $A = 23.1e^{0.0152t}$ .

To find the population of the state in 2000, substitute t = 0 in the given equation:

$A =23.1e^{0.0152(0)}\\\\A = 23.1$

Now, Substitute A = 28.3 into the given equation and solve for t:
$28.3=23.1e^{0.0152t}\\\\e^{0.0152t}=1.2251\\\\0.0152t=\ln(1.2251)\\\\0.0152t=0.2030\\\\t=13.4$

Hence, the population of the state in 2000 was 23.1 million and the population will be 28.3 million after 13.4 years.
