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:
Step-by-step explanation:
Let A should be added in the given polynomial to obtain a sum of zero.
Therefore,
![A + 3 {x}^{2} + 4x + 7= 0 \\ \\ A = 0 - (3 {x}^{2} + 4x + 7 ) \\ \\ A = 0 - 3 {x}^{2} - 4x - 7 \\ \\ A = - 3 {x}^{2} - 4x - 7 \\](https://tex.z-dn.net/?f=A%20%2B%203%20%7Bx%7D%5E%7B2%7D%20%20%2B%204x%20%2B%207%3D%200%20%5C%5C%20%20%5C%5C%20A%20%3D%200%20-%20%283%20%7Bx%7D%5E%7B2%7D%20%20%2B%204x%20%2B%207%20%29%20%5C%5C%20%20%5C%5C%20A%20%3D%200%20-%203%20%7Bx%7D%5E%7B2%7D%20%20%20-%20%204x%20%20-%20%207%20%5C%5C%20%20%5C%5C%20A%20%3D%20%20-%203%20%7Bx%7D%5E%7B2%7D%20%20%20-%20%204x%20%20-%20%207%20%5C%5C%20)
Thus,
should be added in the given polynomial to obtain a sum of zero.
Answer:

???
Step-by-step explanation:
(2³ × 2¹)²
(2⁶ × 2²)
for indices , × become +, plus
÷ become -, minus
so
2⁶+²
2⁸
Answer:
Lateral surface area: 364 yd^2
Total surface area: 624 yd^2
Step-by-step explanation:
Lateral area: 2(14x13) = 364 yd^2
Total area= 364 + 120 + 140 = 624 yd^2
