Answer:

200 ;]

Step-by-step explanation:

“Stuck? Watch a video or use a hint” lol

6 x 100000 = 600000

3 x 1000 = 3000

How many times bigger is 600000 than 3000?

600000/3000 will give you the answer.

Answer:

A. x = 6.08, x = -0.58

Step-by-step explanation:

$\displaystyle \frac{2x}{x-4}-\frac{2x-5}{x^2-10x+24}=\frac{-3}{x-6}$

1. Factor the denominator.

$\displaystyle \frac{2x}{x-4}-\frac{2x-5}{(x-6)(x-4)}=\frac{-3}{x-6}$

2. Multiply the leftmost fraction by (x-6)/(x-6) to get common denominators.

$\displaystyle \Big ( \frac{x-6}{x-6} \Big ) \frac{2x}{x-4}-\frac{2x-5}{(x-6)(x-4)}=\frac{-3}{x-6}$

3. Simplify.

$\displaystyle \frac{2x^2-12x}{(x-4)(x-6)}-\frac{2x-5}{(x-6)(x-4)}=\frac{-3}{x-6}$

4. Combine like terms.

$\displaystyle \frac{2x^2-14x+5}{(x-4)(x-6)}=\frac{-3}{x-6}$

5. Multiply the right side of the equation by (x-4)/(x-4).

$\displaystyle \frac{2x^2-14x+5}{(x-4)(x-6)}=\frac{-3}{x-6} \Big ( \frac{x-4}{x-4} \Big )$

6. Simplify.

$\displaystyle \frac{2x^2-14x+5}{(x-4)(x-6)}=\frac{-3x+12}{(x-6)(x-4)}$

7. "Cancel" out the denominators because they are equivalent.

$2x^2-14x+5=-3x+12$

8. Set the equation equal to 0.

$2x^2-11x-7=0$

Quadratic formula:

$\displaystyle x = \frac{-b\pm \sqrt{b^2-4ac} }{2a}$

9. Factor using the quadratic formula.

$\displaystyle x = \frac{-(-11)\pm \sqrt{(-11)^2-4(2)(-7)} }{2(2)}$

10. Multiply and simplify.

$\displaystyle x = \frac{11 \pm \sqrt{177} }{4}$

11. Plug this into your calculator and solve for x.

$x=6.07603367 \approx 6.08$
$x=-0.57603367 \approx -0.58$

The correct answer is A. x = 6.08, x = -0.58.

You roll a fair 6-sided die what is p (not 3)

Ulleksa [173]

As a fraction, the exact answer is 5/6
In decimal form, the approximate answer is 0.8333

To get this answer, note how there are 5 ways to roll something that isn't a three (1,2,4,5,6) out of 6 ways total (1,2,3,4,5,6)

So you simply divide the two values to get 5/6 = 0.8333

Complete the data table for the function f(x) = -x - 2 + 2.

alexgriva [62]

Given the following function:

$\text{ f(x) = }\sqrt[]{-x\text{ -2}}\text{ + 2}$

y = f(x)

Therefore, let's complete the data table by substituting each x-values to be able to get the respective y-values,

We get,

At x = -2,

$\text{ y = f(x) = }\sqrt[]{-x-2}\text{ + 2}$ $\text{f(-2) = }\sqrt[]{-(-2)-2}\text{ + 2}$ $\text{ = }\sqrt[]{2\text{ - 2}}\text{ + 2}$ $\text{ = }\sqrt[]{0}\text{ + 2}$ $\text{ y = f(-2) = 2}$

Therefore, y = 2 at x = -2.

At x = -3,

$\text{ y = f(x) = }\sqrt[]{-x-2}\text{ + 2}$ $\text{f(-3) = }\sqrt[]{-(-3)-2}\text{ + 2}$ $\text{= }\sqrt[]{3-2}\text{ + 2}$ $\text{= }\sqrt[]{1}\text{ + 2}$ $\text{= }1\text{ + 2}$ $\text{ f(-3) = 3}$

Therefore, y = 3 at x = -3.

At x = -6,

Use the law of Sines to find the missing angle of the triangle. <br> Find m

Whitepunk [10]

Ah...Trigonometry is fun!

The law of sines states:
$\frac{sinA}{a}= \frac{sinB}{b} = \frac{sinC}{c}$
The transitive property (switching the orders of the equations) applies here. Therfore, we can say that $\frac{sinA}{a}=\frac{sinC}{c}$

We then plug in our given values to find C

$\frac{sin24}{77}=\frac{sinC}{162}$
$\frac{162*sin24}{77}=sinC$
Solving, we get 0.8557316387. We're not done yet!

We are trying to find an angle measure, so we'll do the inverse of the ratio we used (sin).

arcsin0.8557316387 (arcsin is the same as inverse sin)
=58.8 (approximate)

So the measure of angle C is 58.8. You could check this by reinserting it into the equation $\frac{sinA}{a}= \frac{sinB}{b} = \frac{sinC}{c}$ .
