2/2, 4/4, 5/5, 7/7, or any fraction with the same numerator and denominator will be equivalent. All fractions equal 1.
=> The first expression on the left: (1 + tan²)
we know that tangent = sin/cos
so tan² = sin²/cos²
the expression is <u>(1 + sin²/cos²)</u>
=> The second expression on the left: (1 - sin²)
we know that (sin² + cos²) = 1
subtract sin² from each side,
and we have (1 - sin²) = (<u>cos²)</u>
=> Multiply the massaged form of the two expressions:
(1 + tan²) (1 - sin²) = (<u>1 + sin²/cos²)</u> (<u>cos²)</u> = (cos² + sin²) = <em>1 </em>qed
<u> </u>
The inequality equation would be 482.75+82.25x1250 <span>subtracting the amount that Hannah already has from the goal would amount to 767.25, therefore she only needs to save up to equal or more than this amount. Dividing this by 82.25 would then give us how many months this would take equal or greater than 9.33 months.</span>
Answer:
4 adults and 6 children
Step-by-step explanation:
9 x 4 = 36
5 x 6 = 30
36 + 30 = 66
There was 4 adults and 6 children
Answer:
See answers below
Step-by-step explanation:
6) 4ab + 13bc (As it is)
7) -6a²b²
8) -3x²
9) 11x²y + 6xy²
10) 8x - (-2x) = 10x
