Answer:

here's your answer v

Step-by-step explanation:

The first number in the sequence, , is -2.

Each number after that is the previous number multiplied by -2.

etc. We start by stating that .

Now we need to show that for all n greater than or equal to 2, each number in the sequence is the previous number multiplied by -2.

this is the answer.

Answer:

a1+= -2; an = - 2a-1, n > 2

Answer:

So, we have the equation:

[tex]y=x^3-x^2-9x+9[/tex]

Usually, we have to do trial-by-error methods like using the Rational Root Theorem to factor cubic polynomials. However, while this may seem like a complicated cubic equation to factor, it has a simple trick to make it much easier!

We can actually factor this polynomial through Factoring by Grouping. With this method, we can factor a cubic polynomial. We split the equation into two parts, like this:

[tex]y=x^3-x^2-9x+9[/tex]

[tex]y=(x^3-x^2)+(-9x+9)[/tex]

Which can be simplified to:

[tex]y=(x^2)(x-1)+(-9)(x-1)[/tex]

We took out a factor of x^2 for the first term and a negative 9 for the second term. As we can see, we now have two terms that are the same:

(x - 1)

We can factor out the (x - 1) like this:

[tex]y=(x^2)(x-1)+(-9)(x-1)[/tex]

[tex]y=(x-1)(x^2-9)[/tex]

Now, this is not the most simplified form. See the x^2-9 term? We can use the Difference of Squares.

In general:

[tex]a^2-b^2=(a-b)(a+b)[/tex]

We have the expression:

[tex](x^2-9)=(x^2-3^2)[/tex]

[tex](x^2-3^2)=(x-3)(x+3)[/tex]

Therefore:

[tex]y=(x-1)(x^2-9)[/tex]

[tex]y=(x-1)(x-3)(x+3)[/tex]

Our fully factored form for y=x^3-x^2-9x+9 is:

[tex]y=(x-1)(x-3)(x+3)[/tex]

Step-by-step explanation:

what do we need to do ? find the 0 solutions for x ?

if that is the case, let's just do all the multiplication first :

(3/2)² × (2/3)⁴x² = x

9/4 × 16/81 x² = x

4/9 x² = x

4/9 x² - x = 0

4x² - 9x = 0

x × (4x - 9) = 0

so, one solution is obviously x = 0.

the second solution is

4x - 9 = 0

4x = 9

x = 9/4

Step-by-step explanation:

Solving for v in the given equation is performed by making v the equation's

subject.

The statement that describes where the error was made is option;

v can be solved for from the  given expression as follows;

[tex]\displaystyle k = \mathbf{\frac{1}{2} \cdot m \cdot v^2}[/tex]

[tex]\displaystyle k \div m = \mathbf{\left(\frac{1}{2} \cdot m \cdot v^2 \right) \div m}[/tex]

[tex]\displaystyle \frac{k}{m} \times 2 = \left( \frac{1}{2} \cdot v^2 \right) \times 2[/tex]

[tex]\displaystyle \frac{2 \cdot k}{m}= \mathbf{v^2}[/tex]

Taking the square root of both sides of the equation gives;

[tex]\pm \sqrt{\displaystyle \frac{2 \cdot k}{m}} = \mathbf{\sqrt{v^2}}[/tex]

Therefore;

[tex]\displaystyle \pm \sqrt{\frac{2 \cdot k}{m} } = v[/tex]

Therefore, the error was made in the step, [tex]\displaystyle \pm \frac{2 \cdot \sqrt{k} }{m} = \sqrt{v^2}[/tex] , which is by

Step-by-step explanation:

First, just multiply 90 by 1/3. 90 is equal to 90/1 as any number divided by 1 is still equal to itself.

[tex]\frac{90}{1}*\frac{1}{3}=\frac{90*1}{1*3}=\frac{90}{3}[/tex]

Now, 90/3 is just 90 ÷ 3.
