Answer:

The answer is 100.5 in^{3}.

Step-by-step explanation:

To solve for the volume of the cylinder, use the cylinder volume formula, which is V = \pi r^{2} h.

Next, plug in the information given from the problem, and the formula will look like V = (\pi) (2 in^{2}) (8 in).

Then, solve the equation, and the answer will be 100.5 in^{3}.

Does the table represent y as a function of x? Justify your answer.​
Otrada [13]

Answer:

  • No

Step-by-step explanation:

As per definition of the function, every x- value (input) has exactly one corresponding y-value (output)

<u>We can see on the table:</u>

  • x = 3.45 and y= 1.72
  • x = 3.45 and y = 3.36

Two same input values with different outputs.

So this not a function

How can I find the angular position in radians of the minute hand of a clock at 5:00, 7:15, an 3:35?
sveticcg [70]
A) 5:00 
<span>At 00 minutes, the minute hand is point straight up. That is one quarter turn of the entire circle. One-fourth of 2π radians is 1/2 π, or π/2 </span>

b) 7:15 
At 15 minutes, the minute hand is pointing straight to the right, along the imaginary positive x-axis, so it has turned through none of the circle. 0 radians.

c) 3:30 
<span>This one isn't as clean as the others. Let's first find the 35 minute position: it occurs at hour number 7. Identify that measuring from 3 (positive x-axis, measuring counter clockwise) you have to turn through 40 minutes worth of clock. 40 minutes represents 40/60 of an entire clock, which reduces to 2/3. 2/3 of all the radians in a circle (2π of them) is 4/3π, or 4π/3. 

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

How many elements does A contains if it has 64 subsets​
Amanda [17]
<h3>Answer:  6</h3>

===========================================================

Explanation:

Rule: If a set has n elements in it, then it will have 2^n subsets.

For example, there are n = 3 elements in the set {a,b,c}. This means there are 2^n = 2^3 = 8 subsets. The eight subsets are listed below.

  1. {a,b,c} .... any set is a subset of itself
  2. {a,b}
  3. {a,c}
  4. {b,c}
  5. {a}
  6. {b}
  7. {c}
  8. { } ..... the empty set

Subsets 2 through 4 are subsets with exactly 2 elements.  Subsets 5 through 7 are singletons (aka sets with 1 element). The last subset is the empty set which is a subset of any set. You could use the special symbol \varnothing to indicate the empty set.

For more information, check out concepts relating to the power set.

-------------------

The problem is asking what value of n will make 2^n = 64 true.

You could guess-and-check your way to see that 2^n = 64 has the solution n = 6.

Another approach is to follow these steps.

2^n = 64\\\\2^n = 2^6\\\\n = 6

Which is fairly trivial.

Or you can use logarithms to solve for the exponent.

2^n = 64\\\\\text{Log}\left(2^n\right)=\text{Log}\left(64\right)\\\\n*\text{Log}\left(2\right)=\text{Log}\left(64\right)\\\\n=\frac{\text{Log}\left(64\right)}{\text{Log}\left(2\right)}\\\\n\approx\frac{1.80617997398389} {0.30102999566399} \ \text{ ... using base 10 logs}\\\\n\approx5.99999999999983\\\\

Due to rounding error, we don't land exactly on 6 even though we should.

What is the area of a circle with a diameter of 16?
Oksana_A [137]

If the diameter is 16, then the radius is 8.

A=(pi) r^2

8*8=64

64*3.14159265359=201.06

201.06 is your answer.
