Answer:

V=4x^3-30x^2+54x

Step-by-step explanation:

From the question we are told that

Breath of cardboard h=6

Length of cardboard l=9

Let x be the height when fold

Generally the new rectangle is  mathematically given as

Breath h'=(6-2x)

Length l'=(9-2x)

Generally the Volume of tray is mathematically given as

V=L*B*H

V=(9-2x)*6-2x*x

V=x(4x^2-30x+54)

V=4x^3-30x^2+54x

Please tell me the what to do with this problem
frez [133]

Because the prices are different, you need to use two variables, one for each price.

Let the price for the plain one be X and the price for the printed one be Y.

You would multiply the number of each shirt by the variable:

3 plain would be 3X and 2 printed would be 2Y.

You then need to add those together to get the total cost:

Total cost = 3X + 2Y

Which of the following Roots would be between 8 and 7
azamat

To find which of the following roots is between "8" and "7" we can calculate the root of which numbers result in 8 and 7. To do this we will power them by 2, this is done because power is the oposite operation to the root. Doing this gives us:

\begin{gathered} 8^2=64 \\ 7^2=49 \end{gathered}

So the root of 64 is 8 and the root of 49 is 7. We need to find the number that is between 49 and 64.

From the options the only one that qualifies is 52. The correct option is b.

A.The observation deck of tall skyscraper 370 m above the street. Determine the time required for a penny to free fall from the
Ainat [17]

Answer:

8.68 seconds

Step-by-step explanation:

Given:

Height of the deck above the street, s = 370 m

Since the condition is of free falling

thus,

initial speed, u = 0

Acceleration of the penny = acceleration due to gravity, g = 9.81 m/s²

Now,

from Newton's equation of motion, we have

s=ut+\frac{1}{2}at^2

here,

s is the distance

a is the acceleration

t is the time

on substituting the values, we get

370=0\times t+\frac{1}{2}\times9.81\times t^2

or

t² = 75.433

or

t = 8.68 seconds
