Answer:

7.57

Step-by-step explanation:

the area = 44/360 × π × r²

7 π = 44/360 × π× r²

eliminate π

7 = 44/360 x r²

r² = 7× 360/44

r² = 57.27

r =√57.27 = 7.57

The function f(x)=501170(0.98)x gives the population of a Texas City x years after 1995. What was the population in 1995?

galina1969 [7]

Answer:

The population of a Texas City in 1,995 was $501,170\ people$

Step-by-step explanation:

we have

$f(x)=501,170(0.98^{x})$

we know that

The population in 1,995 is for $x=0$

substitute the value of $x=0$ in the function f(x)

$f(0)=501,170(0.98^{0})=501,170\ people$

The cylinder shown has a radius of 3 inches. The height is three times the radius. Find the volume of the cylinder. Round your s

MrRa [10]

Answer:

254.5 Inches Cubed

Step-by-step explanation:

Formula for Finding the Volume of a Cylinder: $V=\pi r^2h$

The radius is 3 inches.

$r=3$

The height is three times the radius.

Multiply the radius by three to get the height.

$h=3*3\\h=9$

The height is 9 inches.

Use the formula to find the volume.

$\pi (3)^29= \pi (9)9=81\pi$

The exact volume is 81 $\pi$ inches cubed.

$81 * \pi$ ≈ 254.47

254.47 ≈ 254.5

The volume of the cylinder should be about 254.5 inches cubed.

Solve each inequality (question 20 please, already have 14 and 17 figured out)

r-ruslan [8.4K]

Answer:

$y>\frac{8}{3}$

Step-by-step explanation:

$\frac{3y-4}{0.2}-8>12\\\frac{3y-4}{0.2} > 20\\5(3y-4)>20\\3y-4>4\\3y>8\\y>\frac{8}{3}$

Dividing by 0.2 is the same as multiplying by 5. Check your calculator if you don't believe me.
