Answer:

I think its 262156

Step-by-step explanation:

Answer:

If f(x) = 4ˣ + 12, f(9) = 262156.

Step-by-step explanation:

f(x) = 4ˣ + 12

Substitute input x = 9.

f(9) = 4⁹ + 12

Evaluate 4 to the 9th power.

f(9) = 262144 + 12

Add 262144 and 12.

f(9) = 262156.

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

applying the square root property was applied to only some of the

variables on the left hand side of the equation, rather than the combined

expression on the left hand side of the equation.

Answer:

y = 1/2x - 3

Step-by-step explanation:

y2 - y1 / x2 - x1

-7 - (-1) / -8 - 4

-6/ -12

m = 1/2

y = mx + b

y = 1/2x + b

-1 = 1/2(4) + b

-1 = 2 + b

-3 = b

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:

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.

Step-by-step explanation:

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]
