Answer:
5.656 units
Step-by-step explanation:
Data provided:
coordinates of the point 1 as (−1,−13)
and,
coordinates of the point 2 as (3,−9)
Now,
The distance between the two points whose coordinates is given is calculated using the formula
distance = 
on substituting the respective values, we get
distance = 
or
distance = 
or
distance = 
or
distance = √32
or
distance = 5.656 units
We know that
[the volume of the stack of books]=[area of each book]*[<span>height of the stack]
</span>area of each book=63 in²
height of the stack=15.75 in
<span>so
</span>[the volume of the stack of books]=[63 in²]*[15.75 in]=992.25 in³<span>
the answer is
</span>D) 992.25 in³
Answer:
- cos(θ) = -(√3)/2
- tan(θ) = -(√3)/3
Step-by-step explanation:
Referring to the attached short table of trig functions, we see that the reference angle with sin(θ) = 1/2 is π/6. The table also shows cosine and tangent values for that angle.
In the second quadrant, where π/2 < θ < π, the cosine and tangent are both negative. The values you seek are ...
cos(θ) = -(√3)/2
tan(θ) = -1/√3 = -(√3)/3
<u>Answer:</u>
<h2>
18.38</h2>
<u>Explanation:</u>
since this triangle is a right-angled triangle and one its angles equals 45° then it's an <u>isosceles right triangle</u> which means that the side opposite 45° <em>(the side to the left)</em> is equal to 13 too.
so according to pythagoras theorem c = √(a²+b²)
x =√(13²+13²)
x = √(169+169)
x = √338
x ≈ 18.38
<em>note:</em><em> in the question it's mentioned to find y! and I believe it is just an error! it's about to find x and that's more resonable!</em>
