Answer:
The answer to your question is the letter E. 50
Step-by-step explanation:
Data
height = ?
Width = 80 cm
Length = 40 cm
Volume = 160000 cm³
Formula
Volume of a rectangular prism = Width x length x height
Substitution
160000 = 80 x 40 x height
Solve for height
height = 160000 / 80 x 40
Simplification
height = 160000/ 3200
Result
height = 50 cm
Answer:
a. V = (20-x)
b . 1185.185
Step-by-step explanation:
Given that:
- The height: 20 - x (in )
- Let x be the length of a side of the base of the box (x>0)
a. Write a polynomial function in factored form modeling the volume V of the box.
As we know that, this is a rectangular box has a square base so the Volume of it is:
V = h *
<=> V = (20-x)
b. What is the maximum possible volume of the box?
To maximum the volume of it, we need to use first derivative of the volume.
<=> dV / Dx = -3
+ 40x
Let dV / Dx = 0, we have:
-3
+ 40x = 0
<=> x = 40/3
=>the height h = 20/3
So the maximum possible volume of the box is:
V = 20/3 * 40/3 *40/3
= 1185.185

It is equal to 26 if you didn’t understand you can ask more questions and I’ll help
It looks like they're multiplied, then you can simply add the exponents,
b⁸ * b⁴ = b⁸⁺⁴ = b¹²
remember, b⁸=b*b*b*b*b*b*b*b and b⁴=b*b*b*b
so b⁸ * b⁴ = b*b*b*b*b*b*b*b * b*b*b*b = b¹²
