What is a function in your own words?

1 answer:

4 0

A function is a black box, with a funnel to put numbers in, a chute where
numbers come out, a crank on the side, and some machinery inside.

You put a number in, turn the crank, and a number comes out ... usually
different from the one you put it.

If you do that enough times with enough different numbers, you can figure out
what machinery is inside.

Or, if you know what the machinery is, then when you put a number in,
you can always predict what number will come out.

Which expression is equivalent to StartRoot 128 x Superscript 8 Baseline y cubed z Superscript 9 Baseline EndRoot? Assume y grea

Nataly [62]

Answer:

Option C.

Step-by-step explanation:

The given expression is

$\sqrt{128x^8y^3z^9}$

It can be written as

$\sqrt{(64\cdot 2)\cdot x^8\cdot y^{2+1}\cdot z^{8+1}}$

$=\sqrt{8^2\cdot 2\cdot (x^4)^2\cdot y^{2}\cdot y\cdot (z^{4})^2\cdot z}$

$=\sqrt{(8x^4yz^4)^2\cdot 2yz}$

$=8x^4yz^4\sqrt{2yz}$

Therefore, the correct option is C.

Find an equation of the largest sphere with center (4, 3, 6) that is contained in the first octant.

allochka39001 [22]

See, pls, the offered explanation:
1. equation for sphere has a form: (x-x₀)²+(y-y₀)²+(z-z₀)²=r², where x₀, y₀ and z₀ are points of center (4;3;6), and r - radius of sphere.
2. according to the task the sphere must be in the 1-t octant and must be the largest, it means that among all the possible radius (4-0=4; 3-0=3; 6-0=6) need to choose the shortest one. r=3.
3. summary: <u>(x-4)²+(y-3)²+(z-6)²=3</u>.

Write a recursive rule for the sequence -5, 10, -20 , 40 -80

riadik2000 [5.3K]

For every negative number, you multiply that number by two, and then negative one. For example: -5*2= -10. -10*-1=10.
