A + 1/a= p find a^3 + 1/a^3<br><br><br><br>(1) p^3 + 3p<br><br>(2) 3p<br><br>(3) p^3 - 3p<br><br>​
REY [17]

Answer:

  (3)  p^3 -3p

Step-by-step explanation:

  (a +1/a) = p . . . . . . . given

  (a +1/a)^3 = p^3 . . . . . . . . cube both sides

  a^3 +3a^2(1/a) +3a(1/a)^2 +(1/a)^3 = p^3 . . . . . . expand

  (a^3 +1/a^3) +3(a +1/a) = p^3 . . . . . . . . . . simplify, group

  (a^3 +1/a^3) +3p = p^3 . . . . . . . . . . substitute p for a+1/a

  (a^3 +1/a^3) = p^3 -3p . . . . . . subtract 3p from both sides

If y = x/k where k is a constant, and y = 5 when x = 30, what is the value of y when x = 60?
Alex777 [14]

Answer:

\huge\boxed{\sf y = 10}

Step-by-step explanation:

<u>Given Equation is:</u>

y = x / k

We know that y = 5 when x = 30

Put it in the above equation

5 = 30 / k

k = 30 / 5

k = 6

<u>Now,</u>

y = ? when x = 60

Put it in the above equation

y = x / k

y = 60 / 6

y = 10

\rule[225]{225}{2}
