Do you have a graphing calculator? if yes than all you have to do is hit the y= button in the top left corner and type 1/4x-4 for y1. then you need to hit graph in the top right corner. repeat this process substituting 1/4x-4 and -x+1

How to solve this? \int \frac { 4 - 3 x ^ { 2 } } { ( 3 x ^ { 2 } + 4 ) ^ { 2 } } d x

ivanzaharov [21]

$\Large \mathbb{SOLUTION:}$

$\begin{array}{l} \displaystyle \int \dfrac{4 - 3x^2}{(3x^2 + 4)^2} dx \\ \\ = \displaystyle \int \dfrac{4 - 3x^2}{x^2\left(3x + \dfrac{4}{x}\right)^2} dx \\ \\ = \displaystyle \int \dfrac{\dfrac{4}{x^2} - 3}{\left(3x + \dfrac{4}{x}\right)^2} dx \\ \\ \text{Let }u = 3x + \dfrac{4}{x} \implies du = \left(3 - \dfrac{4}{x^2}\right)\ dx \\ \\ \text{So the integral becomes} \\ \\ = \displaystyle -\int \dfrac{du}{u^2} \\ \\ = -\dfrac{u^{-2 + 1}}{-2 + 1} + C \\ \\ = \dfrac{1}{u} + C \\ \\ = \dfrac{1}{3x + \dfrac{4}{x}} + C \\ \\ = \boxed{\dfrac{x}{3x^2 + 4} + C}\end{array}$

Solve this question. a/7-3<0

valkas [14]

Answer:

$\boxed{\sf{a$

Step-by-step explanation:

You only need to isolate the term a to solve this problem.

Add by 3 from both sides.

$\sf{\dfrac{a}{7}-3+3$

Solve.

0+3=3

a/7<3

Multiply by 7 from both sides.

$\sf{\dfrac{7a}{7}$

Solve.

3*7=21

a<21

As a result, the solution is a<21, which is our answer.

Choose the most appropriate name for the function described below.

DedPeter [7]

T(p) would be an accurate answer. This situation likens to the f(x) function, where y is the function of x and so dependent on x. The cost of the tomatoes is dependent on the price per pound, so cost would be in the f place and price per pound would be in the (x) place.
