944 -360
584
584 -360
224
0-90 is in quad 1
91 -180 is in quad 2
181 - 270 is in quad 3
B. 0
Explanation: at sea level is 0, below sea level would be a negative such as -2, and above sea level is any number above zero, such as 2.
Answer:
(a) The temperature at a specific location as a function of time.
This is a continuous function as the temperature cannot increase in an instant like time.
(b) The temperature at a specific time as a function of the distance due west from New York City.
This is a continuous function as the temperature in one location is affected by its neighboring places.
(c) The altitude above sea level as a function of the distance due west from New York City.
The altitude above sea level can be discontinuous at a cliff, or continuous at very deep hole.
(d) The cost of a taxi ride as a function of the distance traveled.
This is a discontinuous function as the cost still raises if you make a stop.
(e) The current in the circuit for the lights in a room as a function of time.
This is a discontinuous function as the function takes the value of 0 when the switch is off and 1 when the switch is on.
The electron traveling speed makes this discontinuous.
Answer:
a) 7t - 560 ≤ 140 is the required inequality to represent the situation.
Step-by-step explanation:
Let t represent the number of tickets sold.
The amount allocated by school council for all supplies = $560
The selling price of each ticket = $7
The aim to earn profit = more than $140
Goal reached if Number of tickets sold = 100
Now, SP of each ticket is $7
⇒Selling price of t tickets = t x ($7) = 7t
PROFIT = TOTAL SELLING Price - TOTAL COST
or, $140 = 7t - $560
According to the question:
7t - 560 ≤ 140
if t = 100, then the profit earned = 7(100) - 560 = 140
Hence, t = 100 is the possible solution of the given expression.
