a box with no top is constructed from a 10 inch x 12 inch piece of cardboard by cutting out congruent squares from each corner of the cardboard and then folding the resulting tabs. We determined the volume of that box (in cubic inches) is given by V(x) = 4x³ - 44x² + 120x where x denotes the length of the side of the square which is removed from each corner (in inches), 0 < x < 5. Solve the inequality V(x)≥80 analytically and interpret your answer in the context of that example.

The height , H , in feet of an object above the ground is given by h(t)=-16t^2+64t+190 , where t is the time in seconds . What is the height of the object after 2 seconds

Answers

After 2 seconds.
h(2) = -16(2)^2 + 64(2) + 190 = -16(4) + 128 + 190 = -64 + 128 + 190 = 254 feet

Final answer:

The height of the object after 2 seconds is 254 feet.

Explanation:

The height of an object after 2 seconds can be found by substituting t = 2 into the equation for height:

h(2) = -16(2)² + 64(2) + 190

h(2) = -64 + 128 + 190

h(2) = 254

Therefore, the height of the object after 2 seconds is 254 feet.

What is the side length of a cube with a volume of 3375 cm3

Answers

If you would like to know what is the side length of a cube with a volume of 3375 cm^3, you can calculate this using the following steps:

a ... side of a cube
V = a^3
3375 = a^3
a = 15 cm

The correct result would be 15 cm.

The volume of a cube is given by V = s3, where s is the length of a side. Find the length of a side of a cube if the Volume is 1000 cm3.

Yasmine is serving ice cream with the birthday cake at her party.She has perchased 19 1/2 pints of ice cream.She will serve 3/4 of a pint to each guest. How many guests can be served ice cream? Will there be any ice cream left?Justify your thinking

Answers

The number of guests that will be served ice cream is 26 guests and there will be no ice cream left.

The total number of ice cream purchased by Yasmine at her party is:

$\mathbf{=19 (1)/(12) \ pints}$

If each guest gets served with 3/4 pints, then the number of guests that will receive the shared amount of pints is:

$\mathbf{= (3)/(4) \ pints}$

∴

The number of guests that can be served ice cream now is:

$\mathbf{= (19 (1)/(12) \ pints)/( (3)/(4) \ pints)}$

$\mathbf{= ( (39)/(2) \ pints)/( (3)/(4) \ pints)}$

$\mathbf{= { (39)/(2) }* { (4)/(3)}}$

$\mathbf{= { (13)/(1) }* { (2)/(1)}}$

= 26 guests

Therefore, we can conclude that the number of guests that will be served ice cream is 26 guests and there will be no ice cream left.
