In this case, they tell you that C(5) is a function of C(r). Notice the difference in these two; they say that C(5) is actually equal to C(r) meaning that r = 5! This way, plug 5 into the C(r) function to get 6.28 times 5, which gives you 31.4. 

I hope this helped! If it did please rate, thank, and give brainliest answer!

C(r)

so for C(5)  r=5

6.28 x 5 = 31.4 is the answer

What is the answer to this
mash [69]

Answer:

  • 250
  • decay
  • 0.05

Step-by-step explanation:

The value with the exponent is the "multiplier". It is 0.05.

This value is less than 1, so the function represents <em>decay</em>.

The initial value is the number that multiplies the exponential term. It is the value of A when t=0: 250.

  • original amount: 250
  • growth or decay: decay
  • multiplier: 0.05

1. A rectangular pyramid is intersected by a plane to create the frustum shown. If the height of the original pyramid is 14 m, w
oksian1 [2.3K]
The answer needs the volume of the original pyramid minus the small pyramid cut off.
Volume of pyramid = (area of base x height)/3
(12 x 6 x 14)/3 - (4 x 10 x 6)/3 = 256 m^3

The diagram is completely wrong so this problem is actually impossible to solve!
If you slice horizontally across a rectangular pyramid the ratios of the edges will remain constant.
The two rectangles are not the same shape! 12:6 is not the same ratio as 10:4

If the original pyramid in this question was sliced in half the top rectangle of the frustum would be 6 x 3.
In this diagram the height was reduced from 14m to 8m so the top 6m was removed.
If the base was 12 x 6 the top rectangle should be 6/14 smaller = 5.14m by 2.57m (not 10 x 4)

If you are brave you could point this out to your teacher
