Answer:
-1/2
Step-by-step explanation:
the slope of a line that is perpendicular to a given equation of a line, is the negative reciprocal of the original slope
What we could do first is for club A we can add up $23 + $18 which = $40. so the cost would for club A would be $40.
Now club B. Club B charges $14 + 19 that would = $33. so monthly it would be $33
But if you were looking how much money you would spend in 1 year you would have to multiply for club A 40 x 12 which is 480$
and the yearly cost for club B you would have to multiply 33$ times 12 which is $369 per year
<h3>Answer: 133 cm</h3>
============================================================
Explanation:
I'm going to relabel the figure as triangle ABC.
As the instructions mention, we'll use the law of cosines to find the missing side.
- side a = 147
- side b = 166
- angle C = 50 degrees
Use these facts to find side c
c^2 = a^2 + b^2 - 2*a*b*cos(C)
c^2 = 147^2 + 166^2 - 2*147*166*cos(50)
c^2 = 17794.393497
c = sqrt(17794.393497)
c = 133.395628
c = 133
You need to find simple values close to the actual ones asked.
sr(16) = 4 so -sr(17) is slightly below than -4
cr(8) = 2 because 2x2x2=8 so cr(9) is slightly above 2
cr(1) = 1 and cr(8) = 2 so cr(4) is between 1 and 2
Try the others yourself.
