Integrate the following. ∫<img src="https://tex.z-dn.net/?f=5x%5E%7B4%7D%20dx" id="TexFormula1" title="5x^{4} dx" alt="5x^{4} dx

Vadim26 [7]

Answer:

$\displaystyle D) {x}^{5} + \rm C$

Step-by-step explanation:

we would like to integrate the following Integral:

$\displaystyle \int 5 {x}^{4} \, dx$

well, to get the constant we can consider the following Integration rule:

$\displaystyle \int c{x} ^{n} \, dx = c\int {x}^{n} \, dx$

therefore,

$\displaystyle 5\int {x}^{4} \, dx$

recall exponent integration rule:

$\displaystyle \int {x} ^{n} \, dx = \frac{ {x}^{n + 1} }{n + 1}$

so let,

$n = 4$

Thus integrate:

$\displaystyle = 5\left( \frac{ {x}^{4+ 1} }{4 + 1} \right)$

simplify addition:

$\displaystyle = 5\left( \frac{ {x}^{5} }{5} \right)$

reduce fraction:

$\displaystyle = {x}^{5}$

finally we of course have to add the constant of integration:

$\displaystyle \boxed{ {x}^{5} + \rm C}$

hence,

our answer is D)

Which is the solution set of the inequality 15 y minus 9 less-than 36 y greater-than nine-fifths y less-than nine-fifths y less-

Vaselesa [24]

Answer:

C. y<3

Step-by-step explanation:

We are required to determine the solution set of the inequality

$15y-9$

Step 1: Add 9 to both sides

$15y-9+9$

Step 2: Divide both sides by 15

$15y \div 15$

The solution set of the given inequality is: y<3.

The correct option is C.

BRAINLIEST. NEED HELP NOW!!!<br> What is the value of x?

Arturiano [62]

Answer:

x=10

Step-by-step explanation:

these are similar triangles

8 12

------ = -----------

x+4 2x+1

using cross products

8* (2x+1) = 12(x+4)

distribute

16x + 8 = 12x+48

subtract 12x from each side

16x-12x +8 = 12x-12x+48

4x+8 = 48

subtract 8 from each side

4x+8-8 = 48-8

4x = 40

divide by 4

4x/4 = 40/x

x =10
