A. His answer is incorrect. 2 cubed is 2 X 2 X 2, which is 8. Add 4 and you have the answer of 12.
B. He may have multiplied 2 X 3 and then added 4, instead of multiplying 2 three times.

The radius of the large sphere is double the radius of the small sphere.

Vlad [161]

Answer:

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Remember that all the spheres are similar

Let

z ----> the scale factor

V_1 ---> the volume of the large sphere

V_2 ---> the volume of the small sphere

$z^3=\frac{V_1}{V_2}$

<em>Find the scale factor</em>

we know that

The radius of the large sphere is double the radius of the small sphere

The scale factor is 2

$z=2$

substitute the value oz z

$z^3=\frac{V_1}{V_2}$

$2^3=\frac{V_1}{V_2}$

$8=\frac{V_1}{V_2}$

$V_1=8V_2$

The volume of the large sphere is 8 times the volume of the small sphere

Here is a graph of the function y, both continuous and differentiable. For approximately what values of x between -5 and 5 is th

Law Incorporation [45]

From the graph you can determine the first derivative by looking at the turning points. These are where the first derivative is zero.

$y' = x(x-2)(x+2)(x-5)(x+5) \\ \\ y' = x^5 -29x^3 +100x$

Take derivative to get 2nd derivative and set equal to zero:
$y'' = 5x^4 -87x^2 +100 = 0$

Solve for x:
$x^2 = \frac{87 \pm \sqrt{87^2 -2000}}{10} \\ \\ x = \pm 1.11, \pm 4.02$
