Answer:
4
Step-by-step explanation:
Quarter hour on chemistry
Quarter hour on class 2
Quarter hour on class 3
Quarter hour on class 4
Total time....One hour
Fo a circle with radius, r and center (h,k)
te equation is
(x-h)²+(y-k)²=r²
d/2=r
8/2=4=r
center is (-2,-3)
(x-(-2))²+(y-(-3))²=4²
(x+2)²+(y+3)²=16
In place of t, or theta, I'm going to utilize x instead. So the equation is -3*cos(x) = 1. Get everything to one side and we have -3*cos(x)-1 = 0
Let f(x) = -3*cos(x)-1. The goal is to find the root of f(x) in the interval [0, 2pi]
I'm using the program GeoGebra to get the task done of finding the roots. In this case, there are 2 roots and they are marked by the points A and B in the attachment shown
A = (1.91, 0)
B = (4.37, 0)
So the two solutions for theta are
theta = 1.91 radians
theta = 4.37 radians
Answer:
Each class should get 17 tickets. 4 tickets will be left over.
Step-by-step explanation:
157/9=17.444... -> 17 per class
17 x 9 = 153
157-153= 4 left
