Step-by-step explanation:

Let the unknown number be x.

four times a number: 4x

increased by twenty-five: 4x + 25

is: =

thirteen less than six times the number: 6x - 13

PLEASE HELP!!!!! I NEED THIS FAST!!!!!!

Who says V1=V2?
if we simplify we get
(2/3)pir₁³=12pir₂²
for V1 to equal V2


a.
solve for r₁ to find r₁ as a function of r₂
(2/3)pir₁³=12pir₂²
times 3/2 both sides and divide by pi
r₁³=18r₂²
cube root both sides
r₁=∛(18r₂²)

if solve for r₂
(2/3)pir₁³=12pir₂²
divide by 12pi both sides
(1/18)r₁³=r₂²
squer root both sides
√((1/18)r₁³)=r₂



double radius of pond which is r1
√((1/18)r₁³)=r₂
r₁ turns to 2r₁ to double radius
√((1/18)(2r₁)³)=r₂double
√(8(1/18)(r₁)³)=r₂double
(√8)(√((1/18)(r₁)³))=r₂double
√((1/18)r₁³)=r₂ so
(√8)(r₂)=r₂double
(2√2)(r₂)=r₂double
the radius of the tank is multipled by 2√2

Which of the following is true regarding the sequence graphed below?
VikaD [51]

Answer:

Option D. The sequence is not arithmetic because the terms do not have a common difference.

Step-by-step explanation:

We are given  points in a graph as:

             x              y         common difference

             1               1    

             2              4            4-1=3

             3               9           9-4=5

             4              16           16-9=7

             5              25          25-16=9

Clearly from the set of values that are given in the graph we could observe that the function that is formed using these set of values is:

y=f(n)=n² where n=1,2,3,4,5,.....

Hence, the following sequence is not an arithmetic sequence as the common difference is different.

( Common difference is the difference in the y-value  from it's preceding y-value)

Hence, option: D is the true option.

D. The sequence is not arithmetic because the terms do not have a common difference.
