Between 1989 and 1998, the population of smalltown, USA ( in thousands) can be modeled by f(x)=.24x^2 -0.96x + 4, where x=0 repr

Just use derivatives:

f'(x)= .48x-.96 = 0, x = 2, since the coeff of x^2 is +, this is a minimum

x=0 1989, so x = 2 is 1991! :)

The polygons below are similar. Set up a proportion

m_a_m_a [10]

Answer:

Step-by-step explanation:

$\frac{18}{15}$ = $\frac{x}{35}$ ⇔ $\frac{6}{5}$ = $\frac{x}{35}$ ⇔ $\frac{6*7}{5*7}$ = $\frac{x}{35}$ ⇒ <em>x = 42</em>

A sphere has a volume of 4500 cubic inches. What is the radius off the shpere

Goshia [24]

Answer:

The radius of sphere with volume 4500 cubic inches is 10.24 inches.

Step-by-step explanation:

Let V be the volume of the sphere

Given

Volume of sphere = V = 4500 cubic inches

Let r be the radius of the sphere

The volume of the sphere is given by the formula

$V = \frac{4}{3}\pi r^3$

Putting the known values

$4500 = \frac{4}{3} * \frac{22}{7} * r^3\\4500 = \frac{88}{21} * r^3\\r^3 = \frac{21}{88} * 4500\\r^3 = 1073.8636$

Taking cube root on both sides

$\sqrt[3]{r^3} = \sqrt[3]{1073.8636} \\r = 10.2403$

Rounding off to nearest hundredth

The radius is: 10.24 inches.

Hence,

The radius of sphere with volume 4500 cubic inches is 10.24 inches.
