A rectangular box has a volume x^3-64 cubic inches. If the height of the box x-4 inches, what is the area of the base of the box
Zanzabum

Answer:

\purple{ \bold{ \therefore \: A_{base} = {x}^{2}  + 4x +  16}}

Step-by-step explanation:

\because \: V_{box} = A_{base} \times height  \\  \\ \therefore \: A_{base} =  \frac{V_{box}}{height}  \\  \\ \therefore \: A_{base} =  \frac{ {x}^{3}  - 64}{(x - 4)}   \\  \\  \therefore \: A_{base} =  \frac{ {x}^{3}  -  {4}^{3} }{(x - 4)}   \\  \\  \therefore \: A_{base} =  \frac{ \cancel{ ({x}  -  {4})}( {x}^{2}  + 4x +  {4}^{2}  )}{\cancel{ ({x}  -  {4})}}  \\  \\ \purple{ \bold{ \therefore \: A_{base} = {x}^{2}  + 4x +  16}}

Plz help #30 plz explain <br><img src="https://tex.z-dn.net/?f=%20%5Csqrt%7B200%20%7Bx%7D%5E2%20%7By%7D%5E2%20%7Bz%7D%5E2" id="T
Charra [1.4K]

For number 30, its easier if its broken down so were going to make it √200*x^2*y^2*z^2. We can't get a square root of 200 so we will break it into 100*2 to get √2*100*x^2*y^2*z^2. Now let's look at what we can take the square roots of. 2 doesn't have a nice sq. rt. so we will leave it there. 100 has the rt. of 10 so we can make 10√2*x^2*y^2*z^2. X^2 has the root x and we can follow this with the other variables to get 10xyz√2. There is your final simplified answer.

What are the domain and<br> range of the function below?
Olin [163]

Answer:

2nd answer option

Step-by-step explanation:

the domain is the interval or set of valid x values. the range is the same for valid y values.

so, what is the smallest x value we see in the functional graph ?

x = 0

there is no functional value for any x smaller than that.

and then the function goes on and on to the right in all eternity. that means it goes to infinity.

so, domain = [0, infinity)

please consider the round bracket at the end, because "infinity" is not a number.

now for the range and the y values.

in this case I start to ask for the largest y value.

y = 4

for no x value do we get a larger y value.

but it goes down and down in all eternity, going also to infinity, but -infinity (down is negative for y).

so, the range = (-infinity, 4]

"-infinity" is also not a number and therefore not included (hence the round bracket).
