Answer:
P₂ = 
Step-by-step explanation:
Given expression:
Boyle's law:
P₁ V₁ = P₂ V₂
Problem is to find P₂;
Solution:
P₁ V₁ = P₂ V₂
To solve this problem, multiply both sides by 
;
P₁ V₁ x ; = P₂ V₂ x ;
cancels out V₂ on the right hand side;
P₂ =
The solution to the given equation –2|u| = –68 is u = 34, -34.
<h3>What is the solution to the equation?</h3>
Given the equation in the question;
–2|u| = –68
To find u, divide both sides by -2
–2|u| = –68
(–2|u|)/2 = (–68)/-2
|u| = 34
Remove the absolute value term, this create ± on the right side of the equation. ( |x| = ±x )
u = ±34
Hence,
u = 34, -34
Therefore the solution to the given equation –2|u| = –68 is u = 34, -34.

Answer:
(1,3)
Step-by-step explanation:
Rotating clockwise means that you're rotating by a negative angle measure. The rule for rotating -90 degrees is (x,y)->(y,-x). X is (-3,1) so X' should be (1,3) since you negate -3 to get 3 and switch the x and y coordinates.
The picture in the attached figure
Let
h-------> <span>the planes height above ground level at the time of the bird strike
</span>
we know that
sin 7.7°=opposite side angle 7.7°/hypotenuse
where
opposite side angle 7.7°=h
hypotenuse=4 miles
so
sin 7.7°=h/4-------> h=4*sin 7.7°-----> h=0.54 miles
1 mile-----------> 5280 ft
0.54 mile------> x
x=0.54*5280-----> x=2829.79 ft------> 2830 ft
the answer is2830 ft
