Answer: See below

Step-by-step explanation:

Let's split the integral into two parts, by the Sum Rule.

$\int\limits {x-4x^3} \, dx$ [split into 2 integrals]

$\int\limits {x} \, dx -\int\limits {4x^3} \, dx$ [solve integral for each part]

$\frac{1}{2} x^2-x^4+C$ [Remember, we need to add C for constant]

-------------------------------------------------------------------------------------------------

$\int\limits {\frac{1+x}{\sqrt{x} } } \, dx$ [expand into 2 integrals]

$\int\limits {\frac{1}{\sqrt{x} } } \, dx +\int\limits {\frac{x}{\sqrt{x} } } \, dx$ [simplify second integral]

$\int\limits {\frac{1}{\sqrt{x} } } \, dx +\int\limits {\sqrt{x} } \, dx$ [solve integral for each part]

$2\sqrt{x} +\frac{2}{3}x^3^/^2+C$

-------------------------------------------------------------------------------------------------

$\int\limits^4_0 {z(z^1^/^2-z^-^1^/^2)} \, dz$ [distribute]

$\int\limits^4_0 {z^3^/^2-z^1^/^2} \, dz$ [split into 2 integrals]

$\int\limits^4_0 {z^3^/^2} \, dz -\int\limits^4_0 {z^1^/^2} \, dxz$ [solve integral for each part]

$\frac{64}{5} -\frac{16}{3}$ [solve]

$\frac{112}{15}$

-------------------------------------------------------------------------------------------------

D. *Note: I can't put -1 for the interval, but know that the 1 on the bottom is supposed to be -1.

$\int\limits^1_1 {(1+u)(1-u)} \, du$ [expand]

$\int\limits^1_1 {1-u^2} \, du$ [split into 2 integrals]

$\int\limits^1_1 {1} \, du-\int\limits^1_1 {u^2} \, du$ [solve integral for each part]

$2-\frac{2}{3}$ [solve]

$\frac{4}{3}$

$46 shoes; 2.9% tax.

ollegr [7]

The correct answer is 47.33 because you have to multiple 46 times 0.029 and then add 1.33 to the 46 so you get 47.33 hope this helps :)
