To answer this question, we will use the sine law which is illustrated in the attached image.
We are given that:The distance from school to library = a
∠A = 32
∠B = 110
b = 2.2
Substitute with the givens in the relation of the sine law to get a as follows:(sin 32) / (a) = (sin 110) / (2.2)
a = (2.2 sin 32) / (sin 110)
distance from school to library = a = 1.2406 mi
Based on the above calculations, the best choice would be:B. 1.2 mi
Answer:
he will give out about 33 buttons to each grade level
Using Pythagorean Theorem, 15^2-9^2=12^2, so the length AD equals to 12. DC is 12sqrt(3) because the side facing the 60 degree angle is always sqrt(3) times larger than the side facing the 30 degree angle. Lastly, AC is two times AD, which is 24.
Adding the side lengths up, AB+AC+DC+BD=15+24+12sqrt(3)+9=48+12sqrt(3).
The answer is 2.
Since you are subtracting C(x) from R(x), your equation would look like this.
P(x)=-.5x^2+800x-100-(300x+250)
which if you then simplify would be
P(x)=-.5x^2+500x-350
