Step-by-step explanation:

2(4x+2)/2 =20÷2 (to remove to we do the opposite operation)

4x+2=10

4x+2-2=10-2( to remove +2 we do -2)

4x=8

4x/4=8/4

x=2

A spherical balloon is inflated with gas at the rate of 500 cubic centimeters per minute. How fast is the radius of the balloon

zmey [24]

Using implicit differentiation, it is found that the radius is increasing at a rate of 0.0081 cm per minute.

<h3>What is the volume of a sphere?</h3>

The volume of a sphere of radius r is given by:

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

Applying implicit differentiation, the rate of change is given by:

$\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}$

In this problem, we have that:

$\frac{dV}{dt} = 500, r = 70$

Hence the rate of change of the radius is given as follows:

$\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}$

$19600\pi\frac{dr}{dt} = 500$

$\frac{dr}{dt} = \frac{500}{19600\pi}$

$\frac{dr}{dt} = 0.0081$

The radius is increasing at a rate of 0.0081 cm per minute.

How do you model the square root of 16

kotegsom [21]

$\sqrt{16} =\sqrt{4*4}=\sqrt{4}*\sqrt{4}=2*2=4$

3+2x+x-1=2x+x-2<br> answer?

konstantin123 [22]

It’d be 2=-2 ... but then subtract two from both side and the answer is a null set. Also known as “no solution”..

Best of luck in your studies :)

Please help me with this question :) thanks.

Answer:

Opposite sign

Step-by-step explanation:

You can find this because when a point is reflected across the x-axis, its y-coordinate changes its sign. The same is true when reflected across the y-axis. It's x coordinate changes its sign.
