Since V = (4/3) * pi * R^3

If R is halved, V' will reduce by a ratio of (1/2)^3 = 1/8

So V' = (1/8)V

Answer:

Step-by-step explanation:

Given that the radius of a sphere originally r is halved.  We have to find the new volume of the sphere.

Volume of the sphere = \frac{4}{3} \pi r^3

When radius is halved new radius = r/2

Hence volume of the reduced sphere

=\frac{4}{3}\pi (\frac{r}{2} )^3=\frac{1}{8} \frac{4}{3}\pi r}^3\\=\frac{1}{8} V

Volume becomes 1/8 times of the original volume.

What is y=x by a vertcal stretch of 5
kakasveta [241]

Answer: The vertical stretch of 5 in the equation y = x is defined by y=5x.

Explanation:

The given equation is,

y=x

It can be written as,

f(x)=x

The function is defined as S\cdot f(x).

If S\geq 1, then  the function has a vertical stretch by a factor of S units.

If 0, then the function has a vertical shrink by a factor of S units.

Since we have to find the vertical stretch of 5 in the equation y = x.

y=5f(x)

y=5x

The below figure shows the graph of y = x and y=5x.

When you add two rational numbers, each number can be written as a?
ra1l [238]
<span>The correct answer to your question is... a rational #, because w</span><span>hen you add two rational #'s, each # can be written as a rational #. 
</span><span>
Reasoning:
So, adding two rational #'s like adding fractions will result in another fraction of this same form since integers are closed under + and x. Thus, adding two rational #'s produces another rational #.

By the way # means number.
