Step-by-step explanation:
STEP 1
Equation at the end of step 1
(((x3) - 22x2) + x) - 4 = 0
STEP 2
Checking for a perfect cube
2.1 x3-4x2+x-4 is not a perfect cube
<h3>Ans; x=4</h3>
Answer:
6 hours
Step-by-step explanation:
6 inches burns at rate .8 inches in 1 hour
to be 1.2 inches has to burn 6 -1.2 = 4.8 inches of the candle
4.8 inches / .8 inches in 1 hour = 6 hours
9x9 is 81 and yes its very hard haha
If y = xⁿ
∫y dx = xⁿ⁺¹ / (n + 1) + C Provided n ≠ -1.
y = √x
y = x^(0.5)
∫y dx = x^(0.5+1) / (0.5 + 1) = x^(1.5) / 1.5 = x^(1.5) / (3/2)
∫y dx = (2/3) x^(1.5) + C.
∫y dx = (2/3) x^(3/2) + C.
∫y dx = (2/3)√x³ + C
