2 x 11 i believe.

22
/ \
2 11

2 and 11 are both prime numbers which leaves you with nothing left.

Sorry if i’m wrong it’s my first time!

A designer is making a rectangular prism box with maximum volume, with the sum of its length, width, and height 8 in. The length

Sever21 [200]

Answer:

width = 1.8 in

length = 3.6 in

height = $8-3w =8-3(1.8)= 2.6 in$

Step-by-step explanation:

A designer is making a rectangular prism box with maximum volume, with the sum of its length, width, and height 8 in

Let l , w and h are the length , width and height

$l +w+h=8\\l=2w$

Plug it in the first equation

$2w+w+h=8\\3w+h=8\\h=8-3w$

volume the box is length times width times height

$volume = (2w)(w)(8-3w)\\16w^2-6w^3$

To get maximum volume we take derivatived

$v'=32w-18w^2$

set the derivative =0 and solve for w

$0=32w-18w^2\\0=-2w(9w-16)\\w=0 , w= \frac{16}{9}$

width = 1.8 in

length = 2w= 3.6 in

height = $8-3w =8-3(1.8)= 2.6 in$

Initially a wheel rotating about a fixed axis at a constant angular deceleration of 0.5 rad/s 2 has an angular velocity of 0 rad

Zigmanuir [339]

Answer:

$\theta = 5.83\ rad$

Step-by-step explanation:

given,

angular deceleration, α = -0.5 rad/s²

final angular velocity,ω_f = 0 rad/s

angular position, θ = 6.1 rad

angular position at 3.9 s = ?

now, Calculating the initial angular speed

$\omega_f^2 = \omega_i^2 + 2 \alpha \theta$

$0 = \omega_i^2 - 2\times 0.5\times 6.1$

$\omega_i = \sqrt{6.1}$

$\omega_i = 2.47\ rad/s$

now, angular position calculation at t=3.9 s

$\theta = \omega_i t + \dfrac{1}{2}\alpha t^2$

$\theta =2.47\times 3.9 - \dfrac{1}{2}\times 0.5\times 3.9^2$

$\theta = 5.83\ rad$

Hence, the angular position of the wheel after 3.9 s is equal to 5.83 rad.

1) What is the length of the garden in this blueprint?<br> 1”=4 feet <br> 1/4

patriot [66]

Answer:

Area is the measure of the amount of surface covered by something. Area formulas for different shapes are sometimes different, but for the most part, area is calculated by multiplying length times width. This is used when calculating area of squares and rectangles. Once you have the number answer to the problem, you need to figure out the units. When calculating area, you will take the units given in the problem (feet, yards, etc) and square them, so your unit measure would be in square feet (ft.2) (or whatever measure they gave you).

Simplify (4x-8)/(-3x)*(12)/(12-6x)

zloy xaker [14]

$\dfrac{4x-8}{-3x}\cdot\dfrac{12}{12-6x}=\dfrac{4(x-2)}{-x}\cdot\dfrac{4}{-6(x-2)}=\dfrac{4}{-x}\cdot\dfrac{4}{-6}\\\\=\dfrac{2}{-x}\cdot\dfrac{4}{-3}=\dfrac{(2)(4)}{(-x)(-3)}=\dfrac{8}{3x}$
