Option B:
The perimeter of ΔABC is 28 units.
Solution:
AD = 5, DC = 6 and AB = 8
AD and AE are tangents to a circle from an external point A.
BE and BF are tangents to a circle from an external point B.
CD and CF are tangents to a circle from an external point C.
<em>Tangents drawn from an external point to a circle are equal in length.</em>
⇒ AD = AE, BE = BF and CD = CF
AE = 5
AE + BE = AB
5 + BE = 8
Subtract 5 from both sides.
BE = 3
BE = BF
⇒ BF = 3
CD = CF
⇒ CF = 6
Perimeter of the polygon = AE + BE + BF + CF + CD + AD
= 5 + 3 + 3 + 6 + 6 + 5
= 28
The perimeter of ΔABC is 28 units.
Option B is the correct answer.
Answer:
I would pick a, the estimated total to the nearest dollar is 38
Step-by-step explanation:
13.95 rounded is 14
23.50 rounded is 24
24+14=38
The formular which can be used to obtain the monthly charges as a function of the number of cheques written is 9.75 + 0.15x
Charges on account :
- Charge per check written = $0.15
- Monthly services charge = $9.75
The total amount charged monthly, F as a function of the number of cheques written, x can be expressed thus :
Monthly service charge + (charge per check × number of cheques written)
F(x) = 9.75 + 0.15x
Therefore, the charge function which can be used to calculate the total monthly charge on his account ls F(x) = 9.75 + 0.15x
