Show that the equation x^3 + 6x - 5 = 0 has a solution between x = 0 and x=1

Answers

Answer 1

Answer:

Step-by-step explanation:

Show That The Equation X^3 + 6x - 5 = 0 Has A Solution Between X = 0 And X=1
Show That The Equation X^3 + 6x - 5 = 0 Has A Solution Between X = 0 And X=1
Answer 2

Solve the equation for 0 and 1:

x^3 + 6x -5

Replace x with 0:

0^3 + 6(0) -5 = -5

Replace x with 1:

1^3 + 6(1) -5 = 1+6 -5 = 2

Because the value of f(0) is negative and the value of f(1) is positive then there is at least one value of x between 0 and 1 that f(x) = 0

Simplify ^75 select the correct answer

Answers

Answer:

to simplify the square root of 75, first I recognize that the perfect square 25 goes into it. So 75 = 25 x 3. Therefore the square root of 75 equals the square root of 25 times the square root of 3. And that means just 5 times the square root of 3.

Step-by-step explanation:

The square root of √75 is 5√3.

What is Radical?

The √ symbol that is used to denote square root or nth roots. Radical Expression - A radical expression is an expression containing a square root.

A radical notation is an expression that incorporates a root, such as the square or cube root.

Given:

We have to find the square root of 75.

So, we have to factories 75 as

= 25 x 3

and, the square root of 25 is 5.

Then, √75 = √( 5 x 5 x 3)

                  = 5√3.

The area of a square is 676 square root. what is the perimeter of the square?

Answers

Answer:

the perimeter of the square is 104

Step-by-step explanation:

to find the perimeter of a square we need to use the formula P = 4a

P is perimeter and a is the side of the square

if a is the side and the formula of Area is A = a^2

that means the side of the square is a = 26 because 26 * 26 = 676

now we take 26 and place it in the a spot of the perimeter formula

P = 4 * 26   (P = 104)

Answer:

Here we will show you step-by-step with detailed explanation how to calculate 35 divided by 10 using long division.

Before you continue, note that in the problem 35 divided by 10, the numbers are defined as follows:

35 = dividend

10 = divisor

Step-by-step explanation:

ywy

The solution to the expression 35 divided by 10 is 3.5

Given data:

The first number is represented as p.

The value of p = 35

The second number is represented as q.

The value of q = 10

Now, the expression is 35 divided by 10

So, [tex]A=\frac{p}{q}[/tex]

To solve 35 divided by 10, yu perform the division operation as follows:

Answer:

(x + 7)(3x - 1)

Step-by-step explanation:

See the steps below:

3x² + 20x - 7 = 3x² + 21x - x - 7 = 3x(x + 7) - (x + 7) = (x + 7)(3x - 1)
Explanation:-

First Method: (By splitting the middle term)

We have to find p and q such that p+q = 20 and

pq = 3×(-7) = -21

Let us looks for the pair of factors of -21 such that their sum is 20 and product is -21.

20 = 21 - 1 and -21 = 3(-7)

∴ 3x² + 20x - 7 = 3x² + 21x - 1x - 7

= 3x(x + 7) -1(x + 7)

= (x + 7)(3x - 1)

Second method: (Using the factor theorem)

m^ 2 + m − 90 factorize

Answers

Answer:

(m+10)(m-9)

Step-by-step explanation:

To factor this equation we want to find two numbers that multiply to -90 but also add/subtract to 1.

Those two numbers are 10 and -9 (10×-9=-90, 10-9=1)

Answer:

[tex](m-9)(m+10)[/tex]

Step-by-step explanation:

When you are given an expression in this format

[tex]ax^2+bx+c[/tex]

You must find two numbers that add up to b while the product is c.

You do trial and error to figure it out for your equation.

[tex]m^2+m-90[/tex]

Hmm... what two numbers add up to 1 and multiplied together equal -90.

Start off with pairs that can equal 90.

45 2

18 5

9 10

Ok, well 45 * 2 does equal 90 but 45 + 2 = 47and 45 + -2 = 43 but there's no way I can make it equal to 1. Next!

18 * 5 equals 90 but 18 + -5 = 13 and 18 + 5 = 23, I can just tell that there's no way I can make this equal to 1.

9 * 10 equals 90, 9 + 10 = 19 but 9 + -10 = -1. Now, that's interesting, We have -1 but we need 1. All we have to do is flip the order. 10 + -9 = 1. And -9 * 10 = -90, PERFECT!

Now use the two numbers and put it in factored form.
