f(X) = 9x^3 + 2x^2 - 5x^3 - 7x + 4 and g(X) = 5x^3 - 7x + 4. what is f(X) - g(X)? Show all of your steps and write your final an

dolphi86 [110]

First we can simplify f(x) to make it a little easier. We can write it as
4x^3+2x^2-7x+4 by combining like terms

The we just subtract g(x) from f(x) and simplify
4x^3+2x^2-7x+4-(5x^3-7x+4) and remember to distribute the negative to g(x)
4x^3+2x^2-7x+4-5x^3+7x-4 (combine like terms)
-x^3+2x^2
In factored form, this becomes
-x^2(x-2)

Hope this helps

I think it would be easy to find it because its 30 feet away and even if he didn't know his feet he could always leave rocks/pebbles to the treasure so he won't lose it.

The graph shows the relationship between mass and volume for pure silver. Use the graph to determine the density of pure silver

Natalija [7]

Answer:

C. Slope and $10.49 g/cm^3$

Step-by-step explanation:

We're missing the graph itself, but I can make an educated guess:

- Assuming x = volume and y = mass:

$p = \frac{m}{v}$

density = mass/volume

x = volume = run

y = mass = rise

mass/volume = rise/run = slope

The slope of the line (assuming the graph is purely linear) represents mass/volume, which is the formula for density.

I had to Google the density of silver itself. Do the math from the graph for a more appropriate answer, as the graph may be less scientifically precise.

A child got 16.67/20 on a test. what is their grade in percent form?

solong [7]

Answer:

83.4% or 83%

Step-by-step explanation:

when trying to find a percent, divide the numerator (# of correct answers) by the denominator (# of total questions possible to get correct)

Which would be 16.67 divided by 20 which equals .8335. Move the decimal point over two placements which would be 83.35. I rounded it up to 83.4. If trying to find a whole number not a decimal it would be 84%. Depending on the grading scale, it would be a B.

THE FUNCTION ARCSINE CAN ALSO BE DEFINED AS?

vodomira [7]

The arcsine, $\sin^{-1}$ , is the inverse of the $\sin$ function. This means that it takes as inputs what would usually be outputs for the $\sin$ function and produces as outputs what would usually be inputs for the $\sin$ function.

This can be particularly useful when you're trying to find an angle on a right triangle, but you've only been given the lengths of the sides. To find any angle $\theta$ in a right triangle, just take $\sin^{-1} \frac{o}{h}$ , where o is the side opposite $\theta$ and h is the hypotenuse of the right triangle.
