How many times larger is the volume of a cone if the height is doubled?

Mathematics
1 answer:
ICE Princess25 [194]3 years ago
3 0
Volume of a cone is given by:
V=1/3πr²h
suppose a cone has radius of r and height,h. The volume will be:
v=1/3πr²h
When the height is doubled, the new volume will be:
v=1/3πr²×2h
v=2/3πr²h
comparing the coefficient of the two volumes, we conclude that when the height was doubled, the volume was also doubled.
The volume will be twice as large as the original volume

12.Divide. (x^2+2x+1/x^2-8x+16)/(x+1/x^2-16
lina2011 [118]
For this case we have the following expression:
 (x ^ 2 + 2x + 1 / x ^ 2-8x + 16) / (x + 1 / x ^ 2-16)
 Rewriting we have:
 (((x + 1) (x + 1)) / ((x-4) (x-4))) / (x + 1 / ((x + 4) (x-4)))
 Then, we cancel similar terms:
 ((x + 1) / (x-4)) / (1 / (x + 4))
 Rewriting:
 ((x + 1) (x + 4)) / (x-4)
 Answer:
 
((x + 1) (x + 4)) / (x-4)

Brian is riding his bike. He biked a distance of 14 miles at a rate of 14 miles per hour. Rearrange the distance formula, d = rt
Mariana [72]

Answer:

60 minutes

Step-by-step explanation:

The distance formula is:

D = RT

Where

D is distance (in miles)

R is rate (in miles per hour)

T is time (in minutes)

Given,

D = 14 miles

R = 14 miles per hour

We want to find T, so we have:

D=RT\\T=\frac{D}{R}\\T=\frac{14}{14}\\T=1

So the time is 1 hour

We want in minutes, and we know 60 minutes is 1 hour, so the time (in minutes) is 60 minutes

Let Mr Gelsomino lost g

Mr Chiarilli lost 240 more than g

so addition is to be used

  • g+240

or

  • 240+g

#2

Just opposite

Mr Gelsomino lost 240 less than c

  • c-240

Write an equation for each translation of y = |x|
nata0808 [166]
If you want to write an equation for an absolute value function this is the parent function y=a|x-h|+k.

In order to write an equation that is 16.5 units right you would do this:

y=|x-16.5|
If you are moving units left the number -16.5 would become 16.5

Remember when you are moving that the number inside is always the opposite sign of where you are moving 

Here is the answer:
y=|x-16.5|
Hope This Helps!
