For all <em>x</em>,
sin²(<em>x</em>) + cos²(<em>x</em>) = 1
so we have
(1 - cos²<em>A</em>) csc²<em>A</em> = sin²<em>A</em> csc²<em>A</em>
and since csc(<em>x</em>) = 1 / sin(<em>x</em>), so the expression reduces to 1.
Answer:
A
Step-by-step explanation:
RR, RY, RG, RP, YY, YG, YP, YR, GG,GP, GR, PP, PR, PY, PG.
All combinations of the four colors are provided in Option A as written out above. The other options are missing combinations.
I hope I helped, Would appreciate Brainliest! ;)
12 gallons = 45.425 liters. (You can divide 45.425 and 12 to get how many gallons are in one liter.) If one liter = 26.9 cents, then we would multiply 45.425 by 26.9. This equals 1,221.9325 cents. That would be about 12 dollars and 22 cents.
Answer:
One number, let's call it x, is 6 more than twice the other number, let's say this number is y.
x= 2y+6
x+y=21
We're left with a system of equations.
If we substitute the first equation in the second we find the value of y.
(2y+6)+y=21
3y+6=21
3y=15
<u><em>y=5</em></u>
Now that we have found the value of y, we can take that value and substitute it in the second equation (since it's easier) to find the value of x.
x+ (5)=21
<u><em>x=16</em></u>
<u><em>Now to check if our answers are correct, we plug in both values into any equation and see if they equate.</em></u>
x+y=21
(16)+(5)=21
21=21
Our solution is correct!
1 yard = 3 feet
0.034 yard = 0.102 feet
0.034 yard to 60 feet
= 0.102 : 60
= 51 /30 000
Answer = 17 /10 000
