Since we know that ratio of AB : AC is 1 : √2, then we can more or less use those values for the sides, check the picture below.
so we're really looking for tan(2A). Let's bear in mind that tan²(θ) is just another way to write [ tan(θ) ]².
Answer:
<h2>(-∞,∞) Bottom answer</h2>
I hope this helps you with your algebra
Assuming the 100 people sampled are representative of the population as a whole, the answer is choice B. Most people who own a cat would dislike dogs according to the survey. We can only talk about cat owners since the 100 people selected are cat owners. We can't say anything about pet owners in general.
To evaluate the answer of Harry:
8-(2+5)8-(2+5)
= -55
To evaluate the answer of Terry:
8-2+58-2+5
= 66
HH = -55
TT = 66
H-TH-T
5-65-5
= -65
The 20th costumer will get both.
You have to fine the least common multiple of both numbers. So the closest those two numbers have is 20.
