Arada [10]

Answer: 64\ ft^3

Step-by-step explanation:

Given

The dimension of the box is

\text{width w=}8\ ft\\\text{height h=}2\ ft\\\text{length l=}4\ ft

Space occupied by the box is equal to its volume i.e.

\Rightarrow V=l\times b\times h\\\Rightarrow V=4\times 8\times 2\\\Rightarrow V=64\ ft^3

The volume of the box is 64\ ft^3.

Snoopy the dog is on a 11-ft long chain that is attached to the corner of a garage (see the picture below). If the chain does no
seropon [69]
11*2 = 22 (calculating the diameter)

Using πD for the area:
π * 22 = 22π

Getting 3/4 of the area because the dog can not move past the corners of the garage;

22π * 3/4 = 16.5π

Getting the answer in feet^2:
16.5 * 3.14 = 51.84 feet^2

Hope this helps! :)

If f(x) = (5x^3 - 4)^4, then what is f '(x)?
vlabodo [156]
You apply the rule to put the exponent in front, and lower it by one. But since this is a nested expression, you apply it twice:

4*(5x^3-4)^3 * 3*5x^2 =

60x^2 (5x^3-4)^3

Find the equation of the line specified. The slope is -7, and it passes through ( 5, -3).
Montano1993 [528]
The general equation of a line is
y= ax + b
where a is the slope
So a = -7
So y= -7x + b
But it passes through the point (5, -3)
Substitute the coordinates to calculate b:
So -3 = -7(5) + b
-3 = -35 + b
b= 35-3
b= 32
So the equation of the line of slope -7 and passing through the point (5, -3) is
y= -7x + 32
