Which expression is a perfect cube

Mathematics
1 answer:
mamaluj [8]2 years ago
6 0

Answer: some perfect cubes are

8 (2^3)

27 (3^3)

64 (4^3)

there are many perfect cubes

maybe there is more to this question?

Step-by-step explanation:

A perfect cube of a number is a number that is equal to the number, multiplied by itself, three times. If x is a perfect cube of y, then x = y3. Therefore, if we take the cube root of a perfect cube, we get a natural number and not a fraction. Hence, 3√x = y. For example, 8 is a perfect cube because 3√8 = 2.

To compute the value of investment in 5 years. We use compounded annually equation. And add 2000 Yearly to the compounded value

A = P * (1 + (r/n))^(n*t)

A<span> = total amount  = Unknown</span>
P<span> = principal or amount of money deposited, = 2000 usd</span>
r<span> = annual interest rate  = 2.25%</span>
n<span> = number of times compounded per year = 1</span>
t<span> = time in years = 5
</span>
Solution 
Year1 : A1 = 2000 * (1 +(0.025/1))^(1*1) = 2045
Year2 : A2 = (2000+2045)*(1 +(0.025/1))^(1*1) = <span>4136.01
Year3 : A3 = (2000+</span>4136.01))*(1 +(0.025/1))^(1*1) = <span>6274.07 
Year4 : A4 = </span>(2000+6274.07 ))*(1 +(0.025/1))^(1*1) = <span>8460.24 
Year5 : A5 = </span>(2000+8460.24 ))*(1 +(0.025/1))^(1*1) = 1<span>0695.6 </span>

Ariel was told the x intercept and the y intercept of a line with a positive slope. Yet, it was impossible for Ariel to find the
alexdok [17]

A line has the following standard equation form:

y = m x + b

where m is the slope and b is the y intercept

 

So if Ariel cannot find the slope, then this would only mean that m = 0, there is no slope. And hence the line is either a straight vertical line or straight horizontal line.

 

Answer:

<span>There is no slope</span>
