Mrs. Coughlin bought 2.25 pounds of turkey at $4.96 per pound and 0.75 pound of provolone cheese at $5.20 per pound. If Mrs. Coughlin gave the cashier $20, how much change will she receive?
=====================================================
Work Shown:
She paid 2.25*4.96 = 11.16 for the turkey
She paid 0.75*5.20 = 3.90 for the cheese
In total, the two amounts add to 11.16+3.90 = 15.06
The amount of change she'll get is 20 - 15.06 = 4.94 dollars
To calculate change quickly in your head, notice how the jump from 6 cents to 100 cents is 100-6 = 94 cents. So that moves us from $15.06 to $16, and the rest needed is $4. So that's how we get the overall change to be $4.94.

the height of the wall is half the length. you know the perimeter of the rectangular wall is 48 feet. What is the area of the wall?
Answer:
128 feet²
Step-by-step explanation:
48 = x + x + 2x + 2x = 6x
x = 8
x × 2x = 8 × 16 = 128
a parabolic archway is 12 meters high at the vertex. at a height of 10 meters, the width of the archway is 8 meters. how wide (in m) is the archway at ground level? (round your answer to one decimal place.)
The archway is about 20.8 meters wide at ground level.
We can start by using the formula for a parabolic archway:
y = a\((x-h)^{2}\) + k
where y is the height, x is the width at a certain height, h is the horizontal distance from the vertex to the center of the archway, k represents the height of the vertex, and a determines the shape of the parabola.
We know that the archway is 12 meters high at the vertex, so we can plug in the values we have:
12 = a\((0-h)^{2}\) + k
12 = a\(h^{2}\) + 12
Simplifying this equation, we get:
a = -1/(4h)
We also know that at a height of 10 meters, the width of the archway is 8 meters. Plugging in these values:
10 = a\((4-h)^{2}\) + 12
10 = -1/(4h)\((16-8h)^{2}\) + 12
Simplifying this equation, we get a quadratic equation in terms of h:
0 = 2\(h^{2}\) - 3h - 14
h = 2 or h = -7/2
Since h represents a distance, it cannot be negative, so we take h = 2.
Now we can find the width of the archway at ground level (where y = 0):
0 = a\((x-2)^{2}\) + 12
-a\((x-2)^{2}\) = 12
-a = 12/\((x-2)^{2}\)
Putting our value for a, we get:
1/(4h) = 12/\((x-2)^{2}\)
Solving for x, we get:
x = 20.8 meters
Therefore, the archway is about 20.8 meters wide at ground level.

(q18) Determine c such that f(c) is the average value of the function
on the interval [0, 2].
The correct option is for the value of c, such that f(c) is the average value of the function on the interval [0, 2], is D.
How to find the value of c?The average value of a function on an interval [a, b] is given by:
R = (f(b) - f(a))/(b - a)
Here the interval is [0, 2], then:
f(2) = √(2 + 2) = 2
f(0) = √(0 + 2) = √2
Then here we need to solve the equation:
√(c + 2) = (f(2) - f(0))/(2 - 0)
√(c + 2) = (2 + √2)/2
Solving this for c, we will get:

if we allowed the number of edges between any two nodes to be more than two - i.e. there are 7 roads from city a to city b and 5 roads from city b back to city a and so on, like that for many of the other cities, then which of the two data structures we used for our graph problems, would be able to accurately store that graph information?
If we allow the number of edges between any two nodes to be more than two, we would need to use the adjacency matrix to accurately store that graph information.
The adjacency matrix is a matrix representation of a graph where the rows and columns represent the vertices and the values in the matrix represent the number of edges between two vertices.
In this case, we could have values greater than 1 in the matrix to represent multiple edges between two vertices.
On the other hand, the adjacency list data structure would not be able to accurately store this information, as it represents each vertex and its adjacent vertices in a linked list format.
It would be difficult to represent multiple edges between two vertices using this data structure.

A concave shaving mirror has a radius of curvature of +31.5 cm. It is positioned so that the (upright) image of a man's face is 3.40 times the size of the face. How far is the mirror from the face? Number i Units
The data includes a concave mirror with a radius of curvature of +31.5 cm and magnification of m = 3.40. The formula for magnification is m = v/u, and the focal length is f = r/2. Substituting the values, we get u = v/m, and using the mirror formula, the distance of the object from the mirror is 10.15 cm.
Given data: Radius of curvature of a concave mirror, r = +31.5 cm Magnification produced by the mirror, m = 3.40
We know that the formula for magnification is given by:
m = v/u where, v = the distance of the image from the mirror u = the distance of the object from the mirror We also know that the formula for the focal length of the mirror is given by :
f = r/2where,f = focal length of the mirror
Using the mirror formula:1/f = 1/v - 1/u
We know that a concave mirror has a positive focal length, so we can replace f with r/2.
We can now simplify the equation to get:1/(r/2) = 1/v - 1/u2/r = 1/v - 1/u
Also, from the given data, we have :m = v/u
Substituting the value of v/u in terms of m, we get: u/v = 1/m
So, u = v/m Substituting the value of u in terms of v/m in the previous equation, we get:2/r = 1/v - m/v Substituting the given values of r and m in the above equation, we get:2/31.5 = 1/v - 3.4/v Solving for v, we get: v = 22.6 cm Now that we know the distance of the image from the mirror, we can use the mirror formula to find the distance of the object from the mirror.1/f = 1/v - 1/u
Substituting the given values of r and v, we get:1/(31.5/2) = 1/22.6 - 1/u Solving for u, we get :u = 10.15 cm
Therefore, the distance of the mirror from the face is 10.15 cm. The units are centimeters (cm).Answer: 10.15 cm.

A quadratic function y=f(x) is plotted on a graph and the vertex of the resulting parabola is (3,-4). What is the vertex of the function defined as g (x) =f(x+5)?
Answer:
(-2, -4)
Step-by-step explanation:
y = f(x) = ax²+bx +c
given the vertex is (3, -4)
=> the symetry axis: x = 3
x = -b/2a = 3
so, -b = 6a => b = -6a
the function f(x) = x²-6x + 5
g(x) = f(x+5)
g(x) = (x+5)²-6(x+5)+5
g(x) = x²+10x+25-6x-30+5
g(x) = x²+4x
=> a=1, b=4
find the vertex of the function g :
the symetry axis: x= -4/2(1) => x = -2
y = g(-2) = (-2)²+4(-2)= 4-8 = -4
so, the vertex is (-2, -4)
Answer:
(-2, -4)Step-by-step explanation:

John can invest $4 million, or the foreign currency equivalent of the bank's short term funds, in a covered interest arbitrage with Canada. The the following quotes are provided:S 1.278 CAD/USDF (4 months) 1.2902 CAD/USDUSD 4-month interest rate 2.9%CAD 4-month interest rate 4.7%Calculate the covered interest arbitrage (CIA) profit/Loss (2nd alternative- 1st alterative)?
Therefore, it can be seen that the CIA profit/loss is $111,878.
Here are the steps involved in calculating the covered interest arbitrage (CIA) profit/loss:Borrow $4 million in USD at the 4-month interest rate of 2.9%.
Convert the USD to CAD at the spot rate of 1.278 CAD/USD.
Invest the CAD in a 4-month Canadian deposit account at the 4.7% interest rate.
Sell the CAD forward at the 4-month forward rate of 1.2902 CAD/USD.
After 4 months, repay the USD loan and settle the forward contract.
The profit/loss from the CIA strategy is calculated as follows:
Profit/loss = (Interest earned on CAD deposit - Interest paid on USD loan) - (Forward rate - Spot rate)
In this case, the profit/loss is calculated as follows:
Profit/loss = (0.047 * 4,000,000 - 0.029 * 4,000,000) - (1.2902 - 1.278)
= $112,000 - $0.12
= $111,878
Therefore, the CIA profit/loss is $111,878.

How to complete the conversionFrom the question, we have the following parameters that can be used in our computation:
3 Ib/sec ≈ ? kg/h
To convert pounds per second (lb/sec) to kilograms per hour (kg/h), we can use the conversion factor: 1 lb = 0.45359237 kg.
So, 3 lb/sec = 3 * 0.45359237 kg/sec = 1.361 kg/sec
To convert from per second to per hour, we multiply by the number of seconds per hour:
1.3607771 kg/sec * 3600 sec/hour = 4897.0806 kg/h

determine whether the series is convergent or divergent.
sigma^infinity _n = 0 ln(n^2+3/8n^2+7)
convergent divergent
if it is convergent, find its sum. (if the quantity diverges, enter diverges.)
To determine whether the series is convergent or divergent, we can use the integral test.
First, we note that the function f(x) = ln(x^2+3/8x^2+7) is continuous, positive, and decreasing for x ≥ 1.
Then, we take the integral of f(x) from 1 to infinity:
∫_1^∞ ln(x^2+3/8x^2+7) dx
We can evaluate this integral using integration by parts:
u = ln(x^2+3/8x^2+7) dv = dx
du/dx = (2x)/(x^2+3/8x^2+7) v = x
∫_1^∞ ln(x^2+3/8x^2+7) dx = [xln(x^2+3/8x^2+7)]_1^∞ - ∫_1^∞ (2x)/(x^2+3/8x^2+7) dx
We know that the limit of xln(x^2+3/8x^2+7) as x approaches infinity is infinity, so the first term evaluates to infinity.
For the second term, we can use the substitution u = x^2 to get:
∫_1^∞ (2x)/(x^2+3/8x^2+7) dx = ∫_1^∞ (2du)/(u+3/8u+7)
We can then use partial fractions to write the integrand as:
(2du)/((u/8)+7/8) - (2du)/(u+7)
We can now evaluate the integral:
∫_1^∞ (2du)/(u+3/8u+7) = [2ln(u/8+7/8)]_1^∞ = 2ln(∞/8+7/8) - 2ln(1/8+7/8) = ∞
∫_1^∞ (2du)/(u+7) = 2ln(u+7)]_1^∞ = ∞ - 2ln(8) = ∞
Since both integrals diverge, the original series diverges by the integral test. Therefore, the answer is divergent.

Naomi and Hudson work at a dry cleaners ironing shirts. Naomi can iron 35 shirts per hour, and Hudson can iron 20 shirts per hour. Naomi and Hudson worked a combined 13 hours and ironed 395 shirts. Write a system of equations that could be used to determine the number of hours Naomi worked and the number of hours Hudson worked. Define the variables that you use to write the system.
Answer:
Given that Naomi and Hudson work at a dry cleaners ironing shirts, and Naomi can iron 35 shirts per hour, while Hudson can iron 20 shirts per hour, knowing that Naomi and Hudson worked a combined 13 hours and ironed 395 shirts, to write a system of equations that could be used to determine the number of hours Naomi worked and the number of hours Hudson worked, the following logical reasoning should be performed:
Naomi, working 13 hours, can iron up to 455 shirts (13 x 35), with which, every hour that Hudson has worked and she does not imply a decrease of 15 ironed shirts. Since 455 - 395 equals 60, and 60/20 equals 3, it is determined that Hudson worked 3 hours, while Naomi worked 10 hours.
Thus, the proposed inequality would be the following:
35Y + 20X = 395
