In two or more complete sentences, explain how to solve the cube root equation, ^3√x+1 -2=0
IrinaVladis [17]

Explanation:

The first step is to figure out what the equation is. When unconventional math symbols are used, and when there are no grouping symbols identifying operands, that can be the most difficult step. Here, we think the equation is supposed to be ...

  \sqrt[3]{x+1}-2=0

It usually works well in radical equations to isolate the radical. Here that would mean adding 2 to both sides of the equation, to undo the subtraction of 2.

  \sqrt[3]{x+1}=2

Now, it is convenient to raise both sides of the equation to the 3rd power.

  x+1=2^3=8

Finally, we can isolate the variable by undoing the addition of 1. We accomplish that by adding -1 to both sides of the equation.

  x=7

The equation is solved. The solution is x = 7.

How do you solve this problem? 4a-3b+7a=
Inessa05 [86]
In this problem, you combine the like terms...

4a - 3b + 7a

4a and 7a are like terms so you add them together.

4a + 7a = 11a

So, the answer is: 11a - 3b

AUTOMOBILES The engine torque y (in foot-pounds) of one model of car is given by y = º3.75x2 + 23.2x + 38.8 where x is the speed
Scilla [17]

Answer:

Part 1) The engine speed that maximizes torque is 3,093 rev/min

Part 2)The maximum torque is 74.683\ foot-pounds

Step-by-step explanation:

<u><em>The correct equation is</em></u>

y=-3.75x^{2}+23.2x+38.8

This is the equation of a vertical parabola open downward (because the leading coefficient is negative)

The vertex represent a maximum

The x-coordinate of the vertex represent the engine speed that maximizes torque

The y-coordinate of the vertex represent the maximum torque

Solve the quadratic equation by graphing

using a graphing tool

The vertex is the point (3.093,74.683)

see the attached figure

therefore

The engine speed that maximizes torque is

3.093(1,000)=3,093 rev/min ---> because is in thousands of revolutions per minute

The maximum torque is

74.683\ foot-pounds
