If the diameter of a sphere is doubled, its surface becomes

1 answer:

8 0

Volumes scale as the cube of a corresponding dimension. Therefore, if the radius of a sphere is doubled (r becomes 2r), the surface area becomes 2 squared, or 4 times the original surface area. The volume would become 2 cubed, or 8 times the original volume.

Suppose you pick a tile out of a bag containing 26 tiles marked with the letters A through Z. What is the probability of picking

Liula [17]

Given that <span>a bag contains 26 tiles marked with the letters A through Z.

The probability of picking a letter from the name JACK is 4 / 26

The probability of picking a letter from the name BEN is 3 / 26.

Therefore, the probability of picking a letter from the name JACK or from the name BEN iis given by 4 / 26 + 3 / 26 = 7 / 26 </span>

Write a function g whose graph represents a reflection in the y-axis of the graph F(x)=-x+1

lorasvet [3.4K]

Answer:

$\bold{g(x) = x+1}$

Step-by-step explanation:

Given a function:

$F(x) =-x+1$

To find:

Function $g$ whose graph is a reflection in the y -axis for the given function = ?

Solution:

First of all, let us learn about the reflection of a point ( $x, y$ ) in y axis.

For example, let us consider a point (3, 2) on the coordinate axis.

The reflection of this point in y axis will be (-3, 2)

In other words, <em>To find the image of a point in y axis</em>:

the x coordinate is made of negative sign and y coordinate remains the same.

A line is nothing but a number of points joined together.

So, if we want to find reflection of a line or linear function in y axis, we just make the sign of x as negative.

Given that $F(x) =-x+1$

We can write it as:

$F(x)=y =-x+1$

To find its reflection:

$g(x) = - (-x)+1\\\Rightarrow \bold{g(x) = x+1}$

Please refer to the attached graphs of $F(x)$ and $g(x)$ .

So, the answer is:

$\bold{g(x) = x+1}$

The radii of earth and Pluto are 6,371 kilometers and 1,161 kilometers, respectively. Approximately how many spheres the size of

SCORPION-xisa [38]

Earth volume: (3/4).π.(6371)³ = 1,0832x10¹² km³

Pluto volume: (3/4).π.(1171)³ = 6,555,189,765 km³

How many spheres the size of Pluto does it take to have the same volume as earth?

volume Earth/ volume Pluto = 1,0832x10¹² / 6,555,189,765 = 165.25
