Recall the formula for volume of a cone:  V = (1/3)(base)(height).

Here the volume is V = 62.8 cu in. = (1/3)(pi* r^2)(15 in)
              
                   62.8 cu in      
or, r^2 = --------------------------  = 4 in^2
                (1/3)(3.14)(15 in)

Then the radius of the base is sqrt(4 in^2) = 2 in.

Please help i beg i never get these right

Answer:

\sin(105) = \frac{\sqrt 2 + \sqrt 6}{4}

Step-by-step explanation:

Given

\sin(105^o)

Required

Solve

Using sine rule, we have:

\sin(A + B) = \sin(A)\cos(B) + \sin(B)\cos(A)

This gives:

\sin(105^o) = \sin(60 + 45)

So, we have:

\sin(60 + 45) = \sin(60)\cos(45) + \sin(45)\cos(60)

In radical forms, we have:

\sin(60 + 45) = \frac{\sqrt 3}{2} * \frac{\sqrt 2}{2} + \frac{\sqrt 2}{2} * \frac{1}{2}

\sin(60 + 45) = \frac{\sqrt 6}{4} + \frac{\sqrt 2}{4}

Take LCM

\sin(60 + 45) = \frac{\sqrt 6 + \sqrt 2}{4}

Rewrite as:

\sin(60 + 45) = \frac{\sqrt 2 + \sqrt 6}{4}

Hence:

\sin(105) = \frac{\sqrt 2 + \sqrt 6}{4}

How would you find the empirical probability of getting a red card, if you are choosing a card from an ordinary deck of 52 cards
RSB [31]
You can eliminate choice B because pulling two cards (from 52) does not accurately represent the deck since the sample size is too small.
<span>
There are 26 red cards (13 diamonds and 13 hearts) out of 52 total cards.
 
So the probability is 26/52 = 1/2, which means that the empirical probability can be determined. So choice C is out.
</span><span>  
Another way is to pull out cards at random and make notes as to what color cards you are pulling. Then you can divide the count of red cards by the count of cards total. This is basically what choice A is describing.
 
So the answer is choice A</span>

Use substitution to determine if 0 is a solution of 5x = 5.
natulia [17]

Answer:

No

Step-by-step explanation:

<h2>0      5(x)=5 </h2>

Substitution:

5(0)=5

Anything times 0 equals 0 so

does 0=5?

No
