Answer C
This is because the order can be switched but the answer will not change
By sine law
sin45/16.5= sinB'/22
sinB'= sqrt2/2/16.5*22=
B'= 70.5
B=180-70.5=109.5
Answer:
A. y = cos x
Step-by-step explanation:
The function that we see graphed has the point (0,1), this means whichever trig function f(x) it represents f(0) = 1.
Now, only the cosine function has the property that cos(0) = 1, thus choice A is the correct answer.
Step-by-step explanation:
The price of each ticket will be the slope found from the data.
Slope=m=(y2-y1)/(x2-x1)=(177.5-146.25)/(18-13)
m=6.25 (so the cost of the tickets is $6.25)
Now we can use any data point to solve for b, or the y-intercept of the line:
y=6.25x+b, using (177.5, 18)
177.5=6.25(18)+b
b=$65.00d
So he started with $65.00
