The equation for the surface are of a cylinder is 2 pi r h +2 pi r ^2
That’s means the equation is 2 pi 30 + 2 pi 9 which equals 245cm

In 2010, the estimated population of Los Angeles was 3.79 × 106 people. The population of California that same year was about 9.

Olegator [25]

Answer:

The approximate population of the state of California in 2010 was $37,293,600\ people$

Step-by-step explanation:

Let

x----->the estimated population of Los Angeles in 2010

y----->the estimated population of the state of California in 2010

we know that

$y=9.84x$ ------> equation A

we have

$x=3.79*10^{6}\ people$

Substitute the value of x in the equation A and solve for y

$y=9.84(3.79*10^{6})=37.2936*10^{6}\ people$

$37.2936*10^{6}=37,293,600\ people$

The vertex of this parabola is at (-3, -1). When the y-value is 0, the x-value is 4. What is the coefficient of the squared term

Ivanshal [37]

Hello :
<span>the parabola's equation is : f(x) = a(x+3)²-1
</span><span>the coefficient of the squared expression in the parabola's equation is : a
but ; f(4) = 0
0 = a(4+3)²-1
49a-1=0.....a=1/49
f(x) = 1/49(x-3)²-2</span>
