Evaluate the integral x^3 (x 4 −8)^44 dx by making the substitution u = x^4 - 8
Eduardwww [97]

Answer:

(x^4-8)^45 /180 +c

Step-by-step explanation:

If u=x^4-8, then du=(4x^3-0)dx or du=4x^3 dx by power and constant rule.

If du=4x^3 dx, then du/4=x^3 dx. I just divided both sides by 4.

Now we are ready to make substitutions into our integral.

Int(x^3 (x^4-8)^44 dx)

Int(((x^4-8)^44 x^3 dx)

Int(u^44 du/4)

1/4 Int(u^44 dul

1/4 × (u^45 / 45 )+c

Put back in terms of x:

1/4 × (x^4-8)^45/45 +c

We could multiply those fractions

(x^4-8)^45 /180 +c

Lucy earns money babysitting. Her earnings and hours worked represent a direct variation. She worked for 4 hours and earned $25.
SashulF [63]

For this case we have that by definition, a direct variation is given in the form:

y = kx

Where:

k: It is the constant of proportionality

According to the statement we have to:

y = 25\\x = 4

Substituting:

25 = k4\\k = \frac {25} {4}k = 6.25\ for\ \frac {dollars} {hour}

On the other hand we have:

y = 4\\x = 25\\4 = k25\\k = \frac {4} {25}

k = 0.16\ for\ \frac {hours} {dollar}

Answer:

k = 6.25 for \frac {dollars} {hour}\\k = 0.16 for \frac {hours} {dollar}
