Answer:
Step-by-step explanation:
cosθ = ⅘
sin²θ = 1-cos²θ = 9/25
since θ is in quadrant I, sinθ = √(9/25) = ⅗
sin(2θ) = 2sinθcosθ = 2(⅗)(⅘) = 24/25
You are correct aloe vera is the answer as it has cooling properties <span />
The reflection across y axis of (x,y) would be (-x,y)
thus the answer is b

The probability that the antique painting's value will increase $10.000 is:
P(increase)=0.4
<span>The probability that the antique painting's value will decrease $5.000 is:
</span>P(decrease)=0.6
P(decrease)>P(increase) The probability is bigger the value of the painting to be decreased. But the amount is lower than the amount if the value increases.
We should calculate the expected value in order to decide if it is recommended to invest in the painting. <span>Expected value is the </span>return you can expect for buying the painting.
EV=(-10.000)*0.4+5000*0.6=-4000+3000=-1000
So, the correct answer is B.<span>No I would not recommend investing in the painting, because the expected value of the painting's worth is a decrease of $1000. </span>
The real answer is: it doesn’t matter! a and b are just labels we give to the legs; it doesn’t matter how you pick them, especially since addition is *commutative* (order doesn’t matter). An equality valid way of writing the equation would be:
(leg 1)^2 + (leg 2)^2 = (hypotenuse)^2
But it saves time to just write it as a^2 + b^2 = c^2, where a and b are the lengths of the legs and c is the length of the hypotenuse.
