Answer:
The answer is $88
Step-by-step explanation:
The Math.random () function returns a floating-point, pseudo-random number in the range 0–1 (inclusive of 0, but not 1) with approximately uniform distribution over that range — which you can then scale to your desired range.
Answer: 70 ml of coffee in each cup
Step-by-step explanation:
1 liter = 1000 ml
Amount of coffee given = <em>2.1 liters</em>
<em>2.1 liters = 2.1 * 1000 = 2100 ml</em>
Total number of cups = 30
Amount of coffee in each cup = 
= 
=70
<em>∵ Amount of coffee in each cup </em>= <u>70 milliliters</u>
I think we can use the identity sin x/2 = sqrt [(1 - cos x) /2]
cos x - sqrt3 sqrt ( 1 - cos x) /sqrt2 = 1
cos x - sqrt(3/2) sqrt(1 - cos x) = 1
sqrt(3/2)(sqrt(1 - cos x) = cos x - 1 Squaring both sides:-
1.5 ( 1 - cos x) = cos^2 x - 2 cos x + 1
cos^2 x - 0.5 cos x - 0.5 = 0
cos x = 1 , -0.5
giving x = 0 , 2pi, 2pi/3, 4pi/3 ( for 0 =< x <= 2pi)
because of thw square roots some of these solutions may be extraneous so we should plug these into the original equations to see if they fit.
The last 2 results dont fit so the answer is x = 0 , 2pi Answer
