42 if you multiply 6 and 7 it's 42 and multiply 21 and 2 and it will be 42 so that's the common denominator
Answer:
W = 13.33
X = 13.10
Step-by-step explanation:
You use Trig
S = O/H. C = A/H. T = O/A
For W we have to find Adjacent using Opposite, so we're going to use Tangent
Now we have Tan = O/A and rearrange this to find Adjacent
Tan = O/A --> ATan = O --> A = O/Tan
then we plug in A = 12/Tan(42°) which gives us 13.3273.... I usually round up to the 2nd decimal, so 13.33
To find X we do the same thing with a little bit of additional work
Since we already did the work for the last one, we can just skip a few of those steps
A = 12/Tan(27°) which gives us 26.4322..... or 26.43
But that gives us the whole bottom bit, which is X+W, so just subtract the W
26.43 - 13.33 = 13.10
Sorry if I'm bad at simplifying my wording
I hope this is correct, my math seems right, but the picture is not to scale
Answer:
0
Step-by-step explanation:
Numbers on balls:
1, 4, 7, 7, 8
Try to find the sum of all numbers:
1+4+7+7+8 = 27
According to the rule of 3, any number is dividable by 3 if the sum of it's individual is divided by 3.
27 is dividable by 3, therefore any combination will result a number with a factor of three.
Prime number is the number that is only dividable by 1 and itself. Therefore, any combination using those numbers are not prime number.
So the probability is 0
Y-axis symmetry=(r, theta)=(-r,theta)
-5-5cos(theta)=r
-r=5+5cos(theta)
no y-axis symmetry
x-axis symmetry=(r,theta)=(r,-theta)
cosine is an even function, so yes it is symmetric around x-axis
origin symmetry=(r,theta)=(-r,theta) or (r, theta+pi)
no, as there is no y-axis symmetry
