Answer:
4
Step-by-step explanation:
g(3) = -2(3)^2 -4 = 2(9) -4 = 18-4 = 14
|f(2)| = | 2^2 -3| = | 4-3| = 1
(g(3) +2) = (14+2) = 16
4* |f(2)| = 4*1 = 4
16/4 = 4
There are 6 cups of oatmeal in a box. If each serving is 1/5 of a cup, how many servings are contained in the box?
We have:
1 box has 6 cups
and 1 serving is 1/5 of 1 cup
Then:
Since there is 1/5 of a cup of oatmeal in a serving, this means that each of the 6cups contains 5 servings.
The total number of servings is seen to be
\(5\times6=30\)as there are 6 groups of 5 servings

why does a two-dimensional vector field with zero curl on a region have zero circulation on a closed curve that bounds the region?
This is a consequence of Stokes' theorem in vector calculus, which relates the circulation of a vector field around a closed curve to the curl of the vector field over the surface bounded by the curve.
The theorem states that:
∮C F · ds = ∬S (∇ × F) · dS
where,
F is a vector fieldC is a closed curve that bounds a surface S, ds is an infinitesimal line element along C, ds is an infinitesimal area element over S, and ∇ × F is the curl of F.
If we have a two-dimensional vector field with zero curl on a region, then ∇ × F = 0 over the surface bounded by any closed curve in that region. Applying Stokes' theorem to this situation, we get:
∮C F · ds = ∬S (∇ × F) · dS = 0
since (∇ × F) · dS is zero over the surface S.
Therefore, the circulation of the vector field around any closed curve that bounds the region is zero.
In simpler terms, the curl of a vector field measures how much the field curls or circulates around a point. If the curl is zero, then the field is locally "flat" and does not circulate around any point.
This means that any closed curve in the region must have equal amounts of circulation in opposite directions, which cancels out to zero overall.

What is the perimeter, to the nearest inch, of the kite?
Step-by-step explanation:
In order to calculate the height (distance BC in the diagram) you need to know the distance from point D (the closer of the two measurement points to the kite) to the point directly under the kite, B. Once you know this distance then multiplying this by the tangent of angle b will give you the height.
When it is 4:00 a.m. in Honolulu, it is 2:00 p.m. in London. Just before Paul’s flight from Honolulu to London, he called his friend Nigel, who lives in London, asking what kind of clothing to bring. Nigel explained that London was in the middle of some truly peculiar weather. The temperature was currently 30°C, and was dropping steadily at a rate of 1°C per hour. Paul’s flight left Honolulu at 12:00 p.m. Thursday, Honolulu time, and got into London at 1:00 p.m. Friday, London time. What kind of clothing would have been appropriate for Paul to be wearing when he got off the plane?
Answer:
Paul should be wearing a light jacket appropriate for about 59 F or 15 °C
Step-by-step explanation:
If it is 4:00 a.m. in Honolulu when it is 2:00 p.m. in London, then the difference between times is:
\(d=14-4\\d=10\ hours\)
London is 10 hours ahead of Honolulu.
If Paul left Honolulu at 12:00 p.m, the corresponding time in London was:
\(t=12+10\\t=22 = 10:00\ p.m.\)
Since he arrived in London at 1:00 p.m. at Friday, the flight time was:
\(F= (24-22)+13\\F=15\ hours\)
The flight took 15 hours in total. If the temperature was 30°C when he boarded the flight and it decreases at a rate of 1°C per hour, the temperature when Paul arrives in London is:
\(T=30-(15*1)\\T=15^oC\)
Converting it to Fahrenheit
\(T=(15*\frac{9}{5})+32 \\T=59\ F\)
Paul should be wearing a light jacket appropriate for about 59 F or 15 °C

Suppose that the pairwise comparison method is used to determine the winner in an election. If there are 11 candidates, how many comparisons must be made? comparisons
Total 55 pairwise comparisons must be made to determine the winner in an election with 11 candidates using the pairwise comparison method.
If there are total 11 candidates contested in the election , then the number of pairwise comparisons required to determine the winner using the pairwise comparison method is:
(11-1) + (11-2) + (11-3) + ... + (11-10)
The above expression can be simplified to as 10 + 9 + 8 + ... + 1
It is an arithmetic series (AP) having a common difference of -1 and a first term of 10. To calculate the sum of an arithmetic series the following formula can be utilized to find the total number of possible comparisons :
n/2 [2a + (n-1)d]
Here, n is the total number of terms, a is the first term, and d is the common difference.
In the problem, n = 10, a = 10, and d = -1. putting these values into the formula,
10/2 [2(10) + (10-1)(-1)] = 10/2 [20 - 9] = 10/2 × 11 = 55
So, there are total 55 pairwise comparisons to be made in order to determine the winner in an election with 11 candidates.

equal monthly payments (starting end of first month) on a 6-year, $50,000 loan at a nominal annual interest rate of 10ompounded monthly are:
To calculate the equal monthly payments for a 6-year, $50,000 loan at a nominal annual interest rate of 10% compounded monthly, we can use the formula for the monthly payment on a loan:
P = (r(PV))/(1 - (1 + r)^(-n))
where P is the monthly payment, r is the monthly interest rate (which is the nominal annual rate divided by 12), PV is the present value of the loan (which is $50,000), and n is the total number of monthly payments (which is 6 years times 12 months per year, or 72).
First, we need to calculate the monthly interest rate:
r = 0.10/12 = 0.0083333
Next, we can substitute these values into the formula to calculate the monthly payment:
P = (0.0083333(50000))/(1 - (1 + 0.0083333)^(-72)) = $843.86
Therefore, the equal monthly payments for this loan would be $843.86, starting at the end of the first month.

Consider a situation where your sales have been quite stable in the month, but you have done exceptionally better in the past two days. what trendline is more sensitive to this change?
The trendline has a positive slope and 3-day moving average is the trendline that is more sensitive to this change.
In this question,
Trendlines are used to give traders a good idea of the direction an investment's value might move. In a healthy trend, it's ideal to enter your trades on a pullback (towards the moving average).
Understanding the direction of an underlying trend is one of the most basic ways to increase the probability of making a successful trade because it ensures that the general market forces are working in your favor.
A moving average is a technical indicator that investors and traders use to determine the trend direction of securities. It is one of the commonly used technical tools best known as trend following or lagging indicator, because it is based on past prices.
The sales have been quite stable in the month, but the sales was exceptionally better in the past two days. If the analyst draws a line between these price points, they have an upward trend and 3-day moving average is the trendline that is more sensitive to this change.
The options for this question are a) 3 days moving average, b) 7 days moving average, c) They are both equally sensitive, d) None of them is sensitive to this change.
Hence we can conclude that the trendline has a positive slope and option (A) 3-days moving average is the trendline that is more sensitive to this change is the correct answer.

Stratified sampling should be used if a population is believed to have a skewed distribution for one or more of its distinguishing factors.
If a population is believed to have a skewed distribution for one or more of its distinguishing factors, then stratified sampling should be used. This involves dividing the population into subgroups based on the distinguishing factors and then randomly selecting samples from each subgroup in proportion to its size. This ensures that the sample represents the population accurately, even if it has a skewed distribution. Sample random, synthetic, and cluster sampling methods may not be effective in this case as they do not account for the skewed distribution of the population.

You invest $5,000 dollars in an account at 1.6% interest and interest is compounded
annually (once a year).
a) Write an equation that shows the amount of money you have after x years.
b) How much money would you have after 15 years?
Part (a)
Answer: y = 5000(1.016)^x------------------
Explanation:
You use the compound interest formula
A = P(1 + r/n)^(n*t)
where
A = final amount after t yearsP = amount deposited (principal) = 5000r = decimal form of interest rate = 0.016n = number of times we compound per year = 1t = number of years = x, some unknown numberAfter plugging those values in, you would go from A = P(1 + r/n)^(n*t) to
A = P(1 + r/n)^(n*t)
A = 5000(1 + 0.016/1)^(1*x)
A = 5000(1.016)^x
Since you're using x for the input, it's possible your teacher wants you to use y for the output. So replace A with y to get y = 5000(1.016)^x
==============================================
Part (b)
Answer: 6344.18 dollars--------------------------
Explanation:
Plug x = 15 into the equation we found back in part (a). Use your calculator to simplify. Round to the nearest hundredth which is rounding to the nearest penny.
y = 5000(1.016)^x
y = 5000(1.016)^15
y = 6344.1818561953
y = 6344.18

Sophie used the equation y = x + 1 to represent that the length of a piece of fabric needed for a craft project (y) is always 1 inch greater than the length of the object made with the fabric (x). Which graph represents four solutions to Sophie's equation?
Answer: Last graph, the one with the points (1, 2), (2, 3), (3, 4), and (4, 5)
Step-by-step explanation:
We have the equation y = x + 1
Now we can replace x by different values to get pairs (x, y).
if x = 1, we have:
y = 1 + 1 = 2
then we have the pair (1, 2)
if we have x = 2, then:
y = 2 + 1 = 3
Then we have the pair (2, 3)
So we need to find the graph that has these points.
The only graph that has the points (1, 2) and (2, 3) is the last graph.
