nignag [31]

Answer:

288 ft³

Step-by-step explanation:

Given that

The volume of each box is 1 cubic foot

And, Hollies required 8 of these layers

Now based on the above information

We assume that the dimension of the base layer is 6 by 6

So, the volume of the container is

= Length × Width × Height

where,

Length = 6 ft

Width = 6 ft

And, Height = 8 ft

So,

= 6 ft × 6 ft × 8 ft

= 288 ft³

Chứng minh: x² - 8x + 17 > 0
monitta

Answer: All Real Numbers

x2−8x+17>0  

x2−8x+17=0

For this equation: a=1, b=-8, c=17

1x2+−8x+17=0

x=

−b±√b2−4ac

2a

(Use quadratic formula with a=1, b=-8, c=17)

x=

−(−8)±√(−8)2−4(1)(17)

2(1)

x=

8±√−4

Use the position function s(t) = –16t2 + 800, which gives the height (in feet) of an object that has fallen for t seconds from a
Ostrovityanka [42]

Answer:

96 ft/s

Step-by-step explanation:

We can start by deriving the equation of the velocity, which is the derivative of the position equation:

v(t) = \frac{ds}{dt} = (-16t^2)' + 800' = -32t

After 3 seconds, the wrench would achieve a speed of

v(3) = -32t = -32*3 = -96 ft/s

So it's falling at the rate of 96 ft per second after 3 s
