The volume of a cylinder is 1,0297 cubic

1 answer:

8 0

$\textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ V=10297\\ h=21 \end{cases}\implies 10297=\pi r^2(21)\implies \cfrac{10297}{21\pi }=r^2 \\\\\\ \cfrac{1471}{3\pi }=r^2\implies \sqrt{\cfrac{1471}{3\pi }}=r\implies 12\approx r$

Does this table represent an exponential function? x 1 2 3 4 y 4 16 64 256

4vir4ik [10]

Answer:

Yes, the given table represent an exponential function.

Step-by-step explanation:

Given table is :

x y

1 4

2 16

3 64

4 256

Now we need to identify if the given table represent an exponential function or not. To find that we need to check if we can write the numbers in y-column in form of exponential function $y=ab^x$ .

We see that y-values are basically powers of 4 so we can write the related function as $y=4^x$ .

Which is clearly in form of $y=ab^x$ .

Hence yes, the given table represent an exponential function.

Please help for 10 points and 5 stars with 1 thanks! :]

probability = favourable outcomes/total outcomes

you need 1 banana, out of 4 and there are total of 6 items so probability will be 4/6

when you take out 1 banana, there are 3 banana left and total of 5 items

so probability of this action will be 3/5

now, next action is taking out another banana.

this is NOT an independent event.

so by we will multiply the probabilities of these events according to rule of products.

so the answer is $\frac{4\cdot3}{6\cdot5}=\frac25$

or 2×100/5=40%

John draws a regular five pointed star in the sand, and at each of the 5 outward-pointing points and 5 inward-pointing points he

ycow [4]

Solution : Given points to be fill are : 5 external points + 5 internal points

Total positions to be fill are 5+5 = 10

given number of sea shell to be placed are = 10

Here all sea shell are different so each sea shell is different from any other sea shell

if we interchange the position of any two sea shell we would be getting totally different

arrangement .

We can think this problem like 10 sea shell are to be placed at 10 different places

We start with placing first sea shell .

In the beginning we have 10 positions

once it is placed we pick second sea shell and now we have only 9 vacant places

once it is placed we pick next ses shell and we have 8 vacant places for it

we continue with it till we place the last sea shell for which we would be having

only 1 vacant place.

This way the total number of arrangements we get : 10x9x8x7x6x5x4x3x2x1 = 3628800

ANSWER = 3628800
