Step-by-step explanation:
On plato it doesn't like the ° or spaces in between numbers. I had to re answer so many times because of how picky the website is.
Lets O is the center of the circle and Lets A is a point cut on CD from O
mCD = m<COD
OA is perpendicular bisector of CD so OA = 1/2 CD = 1/2(12.7) = 6.35
Sin (DOA) = AD/OD = 6.35 / 9.06
Sin DOA = 0.7009
<DOA = 44.5°
<COD = 2 x 44.5°
<COD = 89°
mCD = <COD = 89°
Answer: 89°
Answer:
y= 9x + 8
Step-by-step explanation:
Answer:
65.5%
Step-by-step explanation:
Arrival rate, λ = average number of customers per hour = 38
Servive rate, μ = number of customers attended to per hour = 58
Utilization factor, ρ = λ / μ
ρ = 38 / 58
ρ = 0.6551724
Utilization rate (%) = 0.6551724 * 100% = 65.5%
In the triangle XYB
cos(x)=XY/XB
in the triangle AYZ
cos(z)=YZ/AZ
we know that
cos(x)=cos(z) and XY=YZ
therefore
XY/XB=YZ/AZ-------------- > (XY/YZ)=(XB/AZ) remember that XY=YZ
1=(XB/AZ)---------- > XB=AZ---------- > the statement was proved
