Answer:
36 cubes.
Step-by-step explanation:
to find the number of cubes:
first, identify the volume of the box using the formula: LxWxH
18cm x 6cm x 9cm = 972 cm³
next, identify the volume of the cube to be placed:
given: cube with a side length of 3 cm
Thus, volume of the cube is 3³=27cm³
To identify the number of cubes, divide the volume of the box to the volume of the cubes. 972/27 = 36. Thus we need 36 cubes.
It wouldn't let me post the answer. See images for the answer and explanation
The maximum height is the y-coordinate of the vertex (x,y) of the parabola.
First find the x-coordinate using the formula:
Now plug the value into the equation and find the y-coordinate:
The maximum height is 36 feet.
To solve this, you distribute the -y to both terms, 2 and 4y.
It will look something like this: (2*-y)+(4y*-y)
When you simplify, look for any like terms that can be combined, and if none, then leave it as it is.
Your final answer will be: -2y-4y^2
