Answer: 9x^3y^3 (third option)

Step-by-step explanation:

The work looks like a huge mess (sorry, couldn't type it!), but I tried to explain on the right.
Pretty much, I cancelled terms within the fractions first.
Second, I cross simplified.
<em>Then </em>I multiplied the two together.
If you have questions, let me know, and I'll give a more thourough explaination.

The speed of light is 186,182 miles per second. How many miles can light travel in a non-leap year? Express your answer in scien

zepelin [54]

So theres 366 days in a leap year,
you need to find hours, minutes, and then seconds
366 x 24 = 8,784 hours
8,784 x 60 = 527,040 minutes
527,040 x 60 = 31,622,400 seconds
31,622,400 seconds x 186,182 mps = 5.88 x 10^10
therefore light travels 5.88 x 10^10 in one leap year

Step-by-step explanation:

we know ,

area of circle =πr^2

hence we get from the figure that the diameter of circle is 19 cm and we can find radius

r=d/2

r=18/2=9cm

area of semicircle =πr^2/2

area of Semi circle equals to =22*(9)^2/7/2

=127.2857143

12 cos theta minus 16 sin theta is equal to zero find 2 sin theta + cos theta

gayaneshka [121]

Answer:

2sinθ + cosθ = 2

Step-by-step explanation:

12 cos θ - 16 sinθ = 0

=> 3 cos θ -4 sin θ = 0

=> tanθ = 3/4

let P = 3x

B = 4x

=> H= 5x

=> sinθ = P/H = 3/5

cosθ = B/H = 4/5

2sinθ + cosθ

= 2× 3/5 + 4/5

= 6/5+4/5

= 10/5

= 2

=> 2sinθ + cosθ = 2
