PLZ HURRY IT'S URGENT!!!<br> Find the volume of the prism.
Mashutka [201]

Answer:

V = 210 cm³

Step-by-step explanation:

The volume (V) of a cube is calculated as

V = Ah ( A is the area of the base and h is the height )

Here A = 5 × 6 = 30 cm² and h = 7 cm , then

V = 30 × 7 = 210 cm³

Over what interval is the graph of f(x) = –(x + 8)2 – 1 decreasiang<br><br><br><br> help
Degger [83]
Please use " ^ " to denote exponentiation:  

<span>f(x) = –(x + 8)^2 – 1 
Find the first derivative:  f '(x) = -2(x+8)(1)
Set this = to 0:  -2(x+8) = 0
solve for x:  x = -8
Divide the number line into subintervals based upon x=-8:

(-inf, -8) and (-8, inf)

Choose a test value for x from each interval, e. g., -10 from the first interval and 20 from the second.

Subst. this test value into the derivative, shown above.

If the result is + the function is incr on that interval; if - the fn. is decr.

Questions welcome!</span>

What is the percent of change from 8,000 to 2,000?
solong [7]

Answer:

75% markdown

Step-by-step explanation:

If I am not mistaken, you can input this into everyday values like a shirt.

For example: If a shirt costs $8 but is on special for $2 then it is 75% off. Since 2 goes into 8 four times, 2 can be considered 25%. So since percent almost always add up back to 100, you take 100- 25 and you get a 75% markdown.

Or so I think, don't quote me on this.
