A line that includes the point (-1,5) has a slope of 4. What is its equation in slope-intercept
form?
Answer:
y=4x+9
Step-by-step explanation:
The slope intercept form is \(y=mx+b\)
So m=4 and we plug it into the equation \(y=4x+b\)
Since there are x point is -1 and y point is 5 we plug those in replacing the corresponding variables \(5=4(-1)+b\)
So the equation becomes \(5=4+b\)
We add 4 to both sides \(5=4+b\\+4=+4\) so 9 equals b
Then we rewrite the whole equation as \(y=4x+9\)

You invest an initial $300 in an account that has an annual interest rate of 4%, compounded quarterly. How much money will you have in the account after 10 years? Round your answer to the nearest whole number.
Answer:
Step-by-step explanation:
The formula you will want to use for this is one that allows a certain number of compoundings of the interest per year. This is a specific one for compounding continuously, and there is one for finding simple interest. Here is the one we want:
\(A(t)=P(1+\frac{r}{n})^{nt}\) where A(t) is the amount in the account after the compounding occurs over the number of years specified, P is the initial amount in the account, r is the interest rate in decimal form, n is the number of times per year the compounding occurs, and t is the amount of time the money is in the account in years. For us:
P = 300,
r = .04,
n = 4 (quarterly means 4 times), and
t = 10
Filling in:
\(A(t)=300(1+\frac{.04}{4})^{(4)(10)}\) and
\(A(t)=300(1+.01)^{40}\) and
\(A(t)=300(1.01)^{40}\) and
A(t) = 300(1.488863734) so
A(t) = $446.66 or $447

a line segment is divided so that the lesser part is to the greater part as the greater part is to the whole. if is the ratio of the lesser part to the greater part, then the value of
The problem involves a line segment divided into two parts in a specific ratio. The ratio of the length of the lesser part to the length of the greater part is found to be (√2 - 1).
Let the length of the whole line segment be x, and let y be the length of the greater part. Then the length of the lesser part is (x - y).
According to the problem statement, the ratio of the lesser part to the greater part is the same as the ratio of the greater part to the whole. Mathematically, we can write this as:
(x - y)/y = y/x
Simplifying this equation, we get:
x^2 - y^2 = y^2
x^2 = 2y^2
Taking the square root of both sides, we get:
x = y√2
Therefore, the value of the ratio of the lesser part to the greater part is:
(x - y)/y = (√2 - 1)

Carly's family traveled 3/10 of the distance to her grandmother's house on Saturday. They traveled 3/7 of the remaining distance on Sunday. What fraction of the total distance to her grandmother's house was traveled on Sunday?
Answer:
3/10 of the total distance to her grandmother's house was traveled on Sunday
Step-by-step explanation:
Carly's family traveled distance of Saturday = \(\frac{3}{10}\)
Remaining distance =\(1-\frac{3}{10}=\frac{7}{10}\)
They traveled 3/7 of the remaining distance on Sunday.
So, Distance traveled on Sunday =\(\frac{3}{7}(\frac{7}{10})\)
Distance traveled on Sunday =\(\frac{3}{10}\)
Fraction of the total distance to her grandmother's house was traveled on Sunday =\(\frac{3}{10}\)

A music store marks up the instruments it sells by 40%. If the store bought a guitar for $35, what will be its store price? If the price tag on a trumpet says $104, how much did the store pay for it? If the store paid $75 for a clarinet and sold it for $100, did the store mark up the price by 40%?
Answer:
a. $49
b. $74.28
c. No
Step-by-step explanation:
The computation is shown below:
a. The store price is
= Purchase price + markup
= $35 + $35 × 40%
= $35 + $14
= $49
b. The price paid is
Since there is a markup of 40% and when it is added to 100% of cost so the selling price is 140% of the cost or 1.40 of the cost
Now the price paid is
$104 = 1.40 × cost
So, the cost is
= $104 ÷ 1.40
= $74.28
c. Now the markup is
= $100 - $75
= $25
The markup percentage is
= $25 ÷ $75
= 33.33%
No the store does not markup the price by 40%

1. Consider a consumer with utility function
u(x1, x2) = min ( 4 x1 + x2, x1 + 2 x2)
(a) Draw indifference curves passing through points (2; 2), (1; 2) and (4; 2) (Note:
these points may lie on different indifference curves). Make sure you correctly
determine kink points.
(b) Determine all properties of the preferences that you can deduce from the shape of
indifference curves or utility function. For each claimed property, provide either
a formal proof or a graphical visualization that will clearly indicate that the
claimed property holds.
(c) When X -> R2+, does UMP have a solution when Pk = 0? What property of the
preference relation did you use to get your answer?
(d) Assume that prices are positive. Derive the Walrasian demand of each good. Is the
Walrasian demand always single valued? [Hint: graphically depicting the UMP
can pin down the maximizing bundles. If p1=p2 > 4 what can you say about the
location of the utility-maximizing consumption bundle? What is the location if
4 < p1=p2 < 1=2? What about prices such that p1=p2 < 1=2?]
(e) Let p1 = p2 = 1 and w = $60. Suppose that the consumer receives a $10 voucher
from the government that he can spend only on good 1. Draw the new budget
set of the consumer and calculate the quantity of each good demanded by the
consumer. Does receiving the voucher make consumer better-off?
(f) Suppose instead that the government allows the consumer to choose between a
cash payment of $10 that can be spent on both goods and a $10 voucher that
can be spent on good 1 only. Which one would the consumer choose and why?
Would your answer change if the government's assistance were $30? Explain your
answer.
(a) By plugging in different values for x1, we can plot the indifference curves passing through the given points (2, 2), (1, 2), and (4, 2).
(b) The shape of the indifference curves shows convexity.
(c) The property used to determine this is the non-satiation property of preferences.
(d) The Walrasian demand may not always be single-valued.
(e) Receiving the voucher makes the consumer better-off .
(f) The cash payment allows the consumer to maximize utility by making trade-offs
For 4x1 + x2 = x1 + 2x2, rearranging the equation gives x2 = 3x1, representing the linear part of the indifference curves.
For x1 + 2x2 = 4x1 + x2, rearranging the equation gives x2 = 3x1, representing the kink in the indifference curves.
By substituting different values for x1, we can plot the indifference curves. They will be upward sloping straight lines with a kink at x2 = 3x1.
(b) Properties of the preferences deduced from the shape of indifference curves and utility function:
Diminishing Marginal Rate of Substitution (MRS): Indifference curves are convex, indicating diminishing MRS. The consumer is willing to give up less of one good as they consume more of it, holding the other good constant.
Non-Satiation: Indifference curves slope upwards, showing that the consumer prefers more of both goods. They always prefer bundles with higher quantities.
Convex Preferences: The kink in the indifference curves indicates convexity, implying risk aversion. The consumer is willing to trade goods at different rates depending on the initial allocation.
(c) UMP does not have a solution when Pk = 0 and X -> R2+. This violates the assumption of finite resources and prices required for utility maximization. The property used is non-satiation, as a consumer will always choose an infinite quantity of goods when they are available at zero price.
(d) Walrasian demand depends on relative prices:
If p1 = p2 > 4, the maximizing bundle lies on the linear portion of indifference curves, where x2 = 3x1.
If 4 < p1 = p2 < 1/2, the maximizing bundle lies on the linear portion of indifference curves but at lower x1 and x2.
If p1 = p2 < 1/2, the maximizing bundle lies at the kink point where x1 = x2.
Walrasian demand may not be single-valued due to the shape of indifference curves and the kink point, allowing for multiple optimal solutions based on relative prices.
(e) Given p1 = p2 = 1 and w = $60, the initial budget set is x1 + x2 = 60. With a $10 voucher for good 1, the new budget set becomes x1 + x2 = 70. Since p1 = 1, the consumer spends the voucher on good 1, resulting in x1 = 20 and x2 = 40. Receiving the voucher improves the consumer's welfare by allowing more consumption of good 1 without reducing good 2.
(f) If given the choice between a $10 cash payment and a $10 voucher for good 1 only, the consumer would choose the cash payment. It provides flexibility to allocate the funds based on individual preferences. The answer remains the same even if the assistance were $30, as the cash payment still allows optimal allocation based on preferences. Cash payment offers greater utility-maximizing options compared to the voucher, which restricts choices.

Step Let represent the radius of the cylindrical tank in m, let h represent the height of the water in the tank in m; and let V represent the volume of the water in the tank in m3 . Writing an equation for V in terms of and h gives the following result: We are given that the radius of the tank is 6 m, and therefore the radius of the column of water that is being measured remains at a constant 6 Substituting the value 6 into the volume equation gives a simplified equation for V in terms of h, as follows_ V =
The height of the water increasing at the rate of \(\frac{1}{12} \frac{m}{min}\) .
What is a function?
In mathematics, a function is a unique arrangement of the inputs (the domain) and their outputs (the codomain), where each input has exactly one output and the output can be linked to the input.
We need a function to connect the two variables when there are associated rates; in this instance, it is unmistakably volume and height. The equation is:
\(V=\) \(\pi r^{2}h\)
Although radius is mentioned in the formula, it is not a variable in this issue because it is constant. We might change the value in
V=\(\pi(6m)^{2}h\)
We must implicitly differentiate wrt (with respect to) time because the rate in this problem is tied to time
\(\frac{dV}{dt} =(36m^{2} )\) \(\pi\frac{dh}{dt}\)
In the problem, we are given \(3\frac{m^{2} }{min}\) which is \(\frac{dV}{dt}\) .So we substitute this in:
\(\frac{dh}{dt} =\frac{3m^{3}}{min(36m^{2} )\pi }\)
\(=\frac{3}{36\pi} \frac{m}{min}\)

What is standard deviation?The standard deviation (SD, also written as the Greek symbol sigma or the Latin letter s) is a statistic that is used to express how much a group of data values vary from one another.
To estimate the integral I = ∫[1 to 0] \(e^{(x^2)\) dx using Monte Carlo simulation, we can use the following algorithm:
Generate a large number of random points (x, y) in the unit square [0, 1] x [0, 1].Count the number of points (x, y) that fall under the curve of the function \(f(x) = e^{(x^2)\) and within the region defined by the interval [0, 1] on the x-axis and the interval [0, f(1)] on the y-axis.Estimate the area under the curve of f(x) by multiplying the fraction of points that fall under the curve by the area of the region defined in step 2.Multiply the estimated area by the length of the interval [0, 1] on the x-axis to obtain an estimate of the integral I.To stop when the standard deviation of the estimator is less than 0.01, we can keep track of the estimated value of the integral and the number of points generated at each iteration of the algorithm. We can compute the standard deviation of the estimator using the formula:
