Answer:
The equation of a circle is 
.
Step-by-step explanation:
-The equation of a circle is:
(where center is 
, the point 
and the radius known as 
).
-Use the center (5,-4) and the point (5,-2) for the equation:
-Solve the equation:
-After you found the radius, use the center (5, -4) and radius 2 to get the equation of a circle:
-Then, after you have the equation, the radius needs to simplified by the exponent:
I am not really sure but I think the answer is B
It wouldbe D.) because you would do
12-4=x
x would be the number of adults
you would solve for x and get 8 so you would have to solve so it would be D.)
Answer:
12.68°
Step-by-step explanation:
We know all three sides (18, 80, 82), but we only need two: 18, and 82. Why? What we do here is find the arcsin of the first leg divided by the hypotenuse.
arcsin(18/82)
<em>18/82 is the same as 9/41, which equals 0.21951 repeating (all 5 digits after the decimal are repeating, by the way).</em>
arcsin(0.21951)
<em>What you see above this statement equals 0.22131 radians.</em>
0.22131 rad
<em>To convert this to degrees, multiply by 57.2957795.</em>
0.22131 * 57.2957795
<em>0.22131 times 57.2957795 is 12.680128961145.</em>
12.680128961145°
<em>The directions say the final answer has to be two decimal places. So this becomes 12.68 (0 is less than 5, so round down).</em>
12.68°
Angle A is 12.68°.
Answer:
Step-by-step explanation:
We get possible sums from 1 + 1 = 2 to 6 + 6 = 12 when we toss two dices together. Total ways 6*6 = 36
a.
<u>Prime numbers:</u>
- 2, 3, 5, 7, 11 - total 5 outcomes with 15 ways (1+1, 1+2, 1+4, 1+6,2+1, 2+3, 2+5, 3+2, 3+4, 4+1, 4+3, 5+2, 5+6, 6+1, 6+5)
b.
<u>Perfect squares:</u>
- 4, 9 - total 2 outcomes with 3 ways for 4 (1 +3, 2+2, 3+1) and 4 ways for 9 (3+6, 4+5, 5+4,6+3)
- P(perfect square) = (3 + 4)/36 = 7/36
c.
<u>Perfect cube:</u>
- 8 - one outcome with 5 ways (2+6,3+5,4+4,5+3,6+2)
- P(perfect cube) = 5/36
