The late fees for a school library are represented by the function c=.25d where c is the total cost and d is the number of days
a book is late . Compare the functions' y- intercepts and rates of change.

Answer:
City library charges 35 cents every day a book is late
School library charges 25 cents every day a book is late
Step-by-step explanation:
The late fees for a school library are represented by the function c=.25d where c is the total cost and d is the number of days a book is late.
The fees charged by a city library are shown in the table. Table is attached below
For the given table y intercept is 0
slope of the city library is 0.35
slope of school library is 0.25
y interept of both city and school library is 0
So we can say that there is no charge for both library if they are not late
City library charges 35 cents every day a book is late
School library charges 25 cents every day a book is late

Answer:
b = 71 m
A = 83°
C = 29°
Step-by-step explanation:
Many calculators can solve triangles. Apps are available for phone and tablet, or on the internet, like the one used here. In general, it takes less time to use one of these than to type your question into Brainly.
Given two sides and the angle between them, the Law of Cosines is the appropriate relation to use for finding the third side.
b = √(a² +c² -2ac·cos(B))
b = √(76² +37² -2·76·37·cos(67.75°)) ≈ √5015.48
b ≈ 70.82005 ≈ 71 . . . meters
__
One a side and its opposite angle are known, the remaining angles are found using the Law of Sines.
sin(A)/a = sin(B)/b
A = arcsin(a·sin(B)/b) = arcsin(76·sin(67.75°)/70.82005) ≈ 83.33°
A ≈ 83°
C = arcsin(37·sin(67.75°)/70.82005) ≈ 28.92°
C ≈ 29°
Or, you can find the remaining angle from 180° -68° -83° = 29°.
