The answers to the question are:
<h3>a. How to determine the service charge rate for the month of October</h3>
This is the number of calls for the help desk
160000/3200 = 50per call
network center
735000/9800
= 75 per device that was monitored
Electronic mail
100000/10000 =
10 for the mail account
For smart phone support
124600/8900
= 14 per phone extension
<h3>b. Charges to the COMM sector </h3>
for helpdesk
5200 * 0.25 * 0.96 *1.5 calls * $50
= 93600
For network center
(5200 * 0.25 * 0.96) + 600] x 75
= 138600
For Electronic mail
5200 * 0.25 * 0.96 * 10 per email account
= 12480
Smart support charge
5200 * 0.25 * 14 = 18200

Answer:
b=3.1cm
Step-by-step explanation:
2a+b=15.7
a=6.3
2*6.3+b=15.7
12.6+b=15.7
b=3.1cm
Answer:
x=2
Step-by-step explanation:
We will use the secant-secant Formula:
(whole secant) x (external part) = (whole secant) x (external part)
(1+x+4) * (x+4) = (11+x+1) * (x+1)
Combine like terms
(x+5) (x+4) = (x+12) (x+1)
FOIL
x^2 + 4x+5x + 20 = x^2 + x+ 12x + 12
Combine like terms
x^2 + 9 x + 20 = x^2 + 13 x + 12
Bring everything to the left
x^2 + 9 x + 20- (x^2 + 13 x + 12) = x^2 + 13 x + 12-( x^2 + 13 x + 12)
x^2 + 9 x + 20- (x^2 + 13 x + 12) =0
Distribute the minus sign
x^2 + 9 x + 20- x^2 - 13 x - 12 =0
Combine like terms
-4x +8 = 0
Subtract 8 from each side
-4x+8-8=0-8
-4x=-8
Divide each side by -4
-4x/-4 = -8/-4
x=2
point slope form
y-y1 = m(x-x1)
y-5 = -2/15(x--5)
y-5 = -2/15 (x+5)
change to slope intercept form
distribute
y-5 =-2/15x -10/15
y-5 = -2/15x -2/3
add 5 to each side
y = -2/15x -2/3 + 5
y = -2/15x -2/3 + 15/3
y = -2/15x +13/3
