Answer:

x=45

Step-by-step explanation:

This is a triangle so it interior degrees will add up to 180.

Since Line AC is tangent to Circle O at point c, Point C measures 90 degrees.

We can find OAC by using the triangle interior theorem,

$45 + 90 + x = 180$

$135 + x = 180$

$x = 45$

Answer:

100000 = 8 (4) ^t

Step-by-step explanation:

We are multiplying by 4 each time

y = a (4)^t

The initial amount is 8

y = 8 (4)^t

We want to get to 100000

100000 = 8 (4) ^t

Suppose the radius of the sphere is increasing at a constant rate of 0.3 centimeters per second. At the moment when the radius i

elixir [45]

<h2>At the moment when the radius is 24 centimeters, the volume is increasing at a rate of 2171.47 cm³/min.</h2>

Step-by-step explanation:

We have equation for volume of a sphere

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

where r is the radius

Differentiating with respect to time,

$\frac{dV}{dt}=\frac{d}{dt}\left (\frac{4}{3}\pi r^3 \right )\\\\\frac{dV}{dt}=\frac{4}{3}\pi \times 3r^2\times \frac{dr}{dt}\\\\\frac{dV}{dt}=4\pi r^2\times \frac{dr}{dt}$

Given that

Radius, r = 24 cm

$\frac{dr}{dt}=0.3cm/s$

Substituting

$\frac{dV}{dt}=4\pi r^2\times \frac{dr}{dt}\\\\\frac{dV}{dt}=4\pi \times 24^2\times 0.3\\\\\frac{dV}{dt}=2171.47cm^3/min$

At the moment when the radius is 24 centimeters, the volume is increasing at a rate of 2171.47 cm³/min.

There are two outputs of 24. Does this help you determine whether the relation is a function? Explain.

oksian1 [2.3K]

Answer:

This does help you find whether it is a function or not. Since 24 has two outputs, it is not a function.

Step-by-step explanation:

The reason is because for a function to be a function, there must be one input for one out put, it can't have two different outputs.
