Which angle is an exterior angle?<br> i°<br><br> k°<br><br> g°<br><br> a°
Zielflug [23.3K]

Among angles i , k , g , a  ,i and k are the exterior angles.

Given i°, k° ,g° ,a° are some angles and we have to find which angle is exterior angle.

The angle between a side of a polygon and an extended side is known as exterior angle of polygon. The sum of exterior angles of a polygon is equal to 180 degrees. We have to identify exterior angles among i° ,k° ,g° ,a°.

The angle i is an exterior angle because it is formed on a line opposite to angle d.

Angle k is also an exterior angle because it is also formed on opposite side of an angle.

Angle g is not an exterior angle.

Angle a is not an exterior angle.

Hence i and k are exterior angles among i, g, k, a.

The quick ship company uses the function C(w) to calculate the cost in dollars, C, for shipping an item weighing w ounces.
Volgvan

Complete question :

The Quick Ship company uses the function C(w) to calculate the cost in dollars, C, for shipping an item weighing w ounces. C(w) 0.45w 0.35w + 1.6 if 0 < W 16 Which statement about the shipping rate is true?

A.it is possible that an item weighing less then 16 ounces could cost the same as an item weighing more than 16 ounces

B. to find the charge for shipping a package weighing more than 16 ounces, multiply the weight by $.035.

C. Shipping at the second rate will always cost $1.60 more than shipping at the first rate

D. if the weight is greater than 16 ounces,the shipping rate is $.0.35 per ounce, plus $1.60​

Answer:

C. Shipping at the second rate will always cost $1.60 more than shipping at the first rate

Step-by-step explanation:

The shipping rates are :

C(w) = 0.45w

Second rate :

C(w) = 0.35w + 1.6

For the first shipping rate, it only has a rate of change value which varies based on the weight of item to be shipped, C(w) = 0.45w.

However, the second shipping rate includes a fixed rate and rate based on the weight of item. This fixed rate implies that regardless of the weight of item to be shipped, a fixed fee is charged which is $1.60. This means that the shipping fee at the secind rate will always be $1.60 greater than thebfirst shipping rate.
