The value of Tony's investment was $1140 on January 1st. On this date
three years later, his investment was worth $1824. The average rate of
change for this investment was $19 per
(1) day
(2) month
(3) quarter
(4) year
Answer:
Step-by-step explanation:
Average rate of change = (Ending value - Beginning value) / Time elapsed
Using the formula for the average rate of change, we get:
(1824 - 1140) / 1095 = $0.55 per day
(1824 - 1140) / 36 = $19 per month
(1824 - 1140) / 12 = $54 per quarter
(1824 - 1140) / 3 = $228 per year
Therefore, the average rate of change for Tony's investment was $19 per month.

An airplane is flying from New York City to Los Angeles. The distance a travels in miles D is related to the time in second T by the equation D equals 0. 15t. How fast is it flying? Be sure to include the unit
An airplane is flying from New York City to Los Angeles. The distance a travels in miles D is related to the time in second T by the equation D equals 0. 15t. The plane is flying at a speed of 792 feet per second.
The distance a travels in miles D is related to the time in second T by the equation D equals 0. 15t. An airplane is flying from New York City to Los Angeles.
The formula relating distance (D), time (T), and speed (S) is given by
D = ST
This means that the speed of the plane is given by:
S = \frac{D}{T}
From the given formula, we have D = 0.15T.
We need to determine the speed S of the plane.
Substituting D, we have:
S = \frac{D}{T}
= \frac{0.15T}{T}
= 0.15
Therefore, the plane is flying at a speed of 0.15 miles per second. (Remember that the distance is in miles and time is in seconds)
We know that 1 mile is equivalent to 5280 feet. Therefore, to convert miles per second to feet per second, we multiply by 5280.
Thus, the plane is flying at a speed of 792 feet per second.

Which of the following fraction is closest to 0? a. 5/12
b. 2/3
c. 5/6
d. 3/4
Answer:
(a) 5/12
Step-by-step explanation:
to solve this problem you can make all fractions equivalent with 12 as the denominator
a) 5/12
b) 2/3 = 8/12 Multiply top and bottom by 4
c) 5/6 = 10/12 Multiply top and bottom by 2
d) 3/4 = 9/12 Multiply top and bottom by 3
if you compare numerators, the smallest one is the closest to zero, which would be (a) 5/12
Answer:
A 5/12
Step-by-step explanation:
first you need to round these all to /12 so a is 5/12
12/3 is 4 so multiply 4 by two which means b is 8/12
12/6 is 2 so multiply 5 by two which gives us c = 10/12
12/4 is 3 and multiply 3 x 3 which is 9 so d is 9/12
5 is the lowest decimal/fraction which makes it the closest to 0
Brianna works as an interpreter for her city government. She bills $11.25 per quarter-hour or any part of a quarter-hour. Last month, she provided services four times, for 5 hours and 23 minutes, 4 hours and 12 minutes, 5 hours and 38 minutes, and 1 hour and 49 minutes, respectively.
How much did Brianna bill for all four sessions last month?
The word problems shows that Brianna billed $725.63 for all four sessions last month.
How to calculate the amountFor the first session: 5 hours and 23 minutes = 5 x 4 quarters + 3 quarters = 22 + 0.75 = 22.75 quarters.
For the second session: 4 hours and 12 minutes = 4 x 4 quarters + 3 quarters = 16 + 0.75 = 16.75 quarters.
For the third session: 5 hours and 38 minutes = 5 x 4 quarters + 2 quarters = 20 + 0.5 = 20.5 quarters.
For the fourth session: 1 hour and 49 minutes = 1 x 4 quarters + 2 quarters = 4 + 0.5 = 4.5 quarters.
Total time = 22.75 + 16.75 + 20.5 + 4.5 = 64.5 quarters.
Total bill = 64.5 x $11.25 = $725.63.

Step-by-step explanation:
Edge 2020
Work done by the force is 42 units which is correct option(C)
What is Work done?The work done by a force in moving along a vector that is the product of their.
Let the the object move from P(2,-4) to Q(10,1)
Here, the position vectors
\(\vec{p}\) = \(2\vec {i}+(-4)\vec {j}\), \(\vec{q}\) = \(10\vec i+\vec{j}\)
Hence \(\vec{PQ}\) = \(\vec{q}\) -\(\vec{p}\) = \(10\vec i+\vec{j}\) - \(2\vec {i}+(-4)\vec {j}\),
\(\vec{PQ}\) = \(8\vec i+5\vec{j}\)
Force acts in a direction (4,2)
So \(\vec{F}\) = \(4\vec i+2\vec{j}\)
∴ Work done = \(\vec{F}.\vec{PQ}\) = \((4\vec i+2\vec{j})\) \(.(8\vec i+5\vec{j})\)
Work done = 32+10 =42 units
Hence work done by the force is 42 units

Suppose a person offers to play a game with you. In this game, when you draw a card from a standard 52-card deck, if the card is a face card you win $2, and if the card is anything else you lose $1. If you agree to play the game, what is your expected gain or loss (in dollars) per game
The expected loss per game is approximately -$0.31.
The terms we need to consider in this problem are: standard 52-card deck, face cards, and expected gain or loss.
To find the expected gain or loss per game, follow these steps:
1. Determine the probability of drawing a face card.
There are 12 face cards (Kings, Queens, and Jacks) in a standard 52-card deck. So the probability of drawing a face card is \(\frac{12}{52}\), which simplifies to \(\frac{3}{13}\).
2. Determine the probability of drawing a non-face card.
There are 40 non-face cards in the deck (52 cards - 12 face cards). So the probability of drawing a non-face card is \(\frac{40}{52}\), which simplifies to \(\frac{10}{13}\).
3. Calculate the expected gain or loss per game.
Expected gain or loss = (Probability of drawing a face card x gain from drawing a face card) + (Probability of drawing a non-face card x loss from drawing a non-face card)
4. Simplify the equation.
Expected gain or loss = \((\frac{3}{13} (2)) + (\frac{10}{13} (-1))\)
Expected gain or loss = \(\frac{-4}{13}\)
Your expected loss per game is approximately -$0.31 (rounded to two decimal places).
