Write -2x^2 (-5x^2 + 4x^3) in standard form

-2x·-2x·(-5x·-5x+4x·4x·4x) Basically, you write out the number depending on the exponent. So if you have a power/exponent of 3, you write it out multiplied by itself 3 times. Hope this helps!

Answer:

12862.83cm³

Step-by-step explanation:

Volume of the Box: [L×W×H] or [30x30x30] or [27000cm³]

Volume of the Sphere: [ $\frac{4}{3}\pi r^{3}$ ] ( $\pi$ =pi=3.14) (r=radius=15) or [ $\frac{4}{3}$ ×3.14×3375] or [14137.17cm³]

Volume of the empty space: 27000cm³-14137.17cm³=12862.83cm³

Btw there are online tools to help you find the volume of a sphere (just use it after you understand the equation)

Hope I helped!

Write an equation in slope intercept form of a line passing through the given point (8,5) m=3

Zepler [3.9K]

If m(slope)=3, you can start to set up the equation as y=3x+b.

Using y=3x+8, you can plug in the given point being (8,5).

y=5

x=8

5=(3*8)+b

5=24+b

b=-19

The equation would be y=3x-19
