It is feasible to close Hargett St. between Blount Street and Person Street for a day.
Given the traffic flow model described, it is feasible to close Hargett St. between Blount Street and Person Street for a day. The model states that the average daily traffic flow on Hargett St. is 8,000 vehicles per day, with 3,000 vehicles per hour during peak hours. By closing Hargett St. between Blount Street and Person Street for a day, the average daily traffic flow would be reduced by 8,000 vehicles per day. Thus, the total number of vehicles that would be diverted from Hargett St. on the day of the event would be 8,000 vehicles. This amount of traffic would not be too overwhelming for the surrounding streets to handle, since the model states that the average daily traffic flow for those streets is approximately 4,000 vehicles per day.

The region corresponding to the statement P(z<1.4) is the area to the left of z=1.4 on a standard normal distribution. This represents the probability of obtaining a z-score less than 1.4.
The region corresponding to the statement P(-c < z < c) = 0.2 is the area between two values, -c and c, on a standard normal distribution that contains 20% of the total area under the curve. This represents the probability of obtaining a z-score between -c and c.
The region corresponding to the statement P(|z|>c) = 0.2 is the area to the left of z=-c and to the right of z=c on a standard normal distribution that contains 20% of the total area under the curve. This represents the probability of obtaining a z-score that is greater than c or less than -c.
The first statement, P(z < 1.4), refers to the probability that the random variable z is less than 1.4. To sketch this region, we would shade the area to the left of the value 1.4 on the number line.
The second statement, P(-c < z < c) = 0.2, refers to the probability that the random variable z is between -c and c, and that this probability is equal to 0.2. To sketch this region, we would shade the area between -c and c on the number line, and adjust the values of c until the shaded area represents 0.2 of the total area under the curve.
The third statement, P(c < z < k) = -0.2, refers to the probability that the random variable z is between c and k, and that this probability is equal to -0.2. To sketch this region, we would shade the area between c and k on the number line, and adjust the values of c and k until the shaded area represents -0.2 of the total area under the curve.
It is important to note that probabilities cannot be negative, so the third statement is not valid. The shaded area should always represent a positive value between 0 and 1.

Composition rational Feb 19, 7:37:30 PM Find the composition g(f(x)) given that f(x)=(1)/(x+3) and g(x)=x^(2)
The composition of the two given rational functions is another rational function, [tex]g(f(x)) = 1/((x+3)^2)[/tex].
The composition of two functions, f(x) and g(x), is denoted as g(f(x)) and is defined as the function that results from applying g(x) to the output of f(x). In other words, the composition of two functions is the function that results from plugging one function into another function.
To find the composition [tex]g(f(x))[/tex], we need to substitute the expression for [tex]f(x)[/tex] into the expression for [tex]g(x)[/tex] wherever we see an "x".
Given that [tex]f(x)=(1)/(x+3)[/tex] and [tex]g(x)=x^2[/tex], the composition [tex]g(f(x))[/tex] can be found as follows:
[tex]g(f(x)) = g((1)/(x+3)) = ((1)/(x+3))^(2) = (1^(2))/((x+3)^(2)) = 1/((x+3)^(2))[/tex]
Therefore, the composition [tex]g(f(x)) = 1/((x+3)^2)[/tex].

the product (2x^(4)y)(3x^(5)y^(8))is equivalent towhat polynomial must be added to x^(2)-2x+6 so that the sum is 3x^(2)+7x
The polynomial that must be added to x^(2)-2x+6 is 2x^(2) + 9x - 6.
To find the product of the two polynomials (2x^(4)y)(3x^(5)y^(8)), we need to use the distributive property and combine like terms.
The distributive property states that a(b+c) = ab+ac. So, we can distribute the first polynomial to each term in the second polynomial:
(2x^(4)y)(3x^(5)y^(8)) = (2x^(4)y)(3x^(5)) + (2x^(4)y)(y^(8))
Next, we can combine like terms by adding the exponents of the variables:
= 6x^(4+5)y^(1+8)
= 6x^(9)y^(9)
So, the product of the two polynomials is 6x^(9)y^(9).
To find the polynomial that must be added to x^(2)-2x+6 so that the sum is 3x^(2)+7x, we can set up an equation:
x^(2)-2x+6 + (a+bx+cx^(2)) = 3x^(2)+7x
Then, we can rearrange the equation to solve for the polynomial:
a+bx+cx^(2) = 3x^(2)+7x - x^(2) + 2x - 6
a+bx+cx^(2) = 2x^(2) + 9x - 6

The function f(x) is shown on the graph.
The graph shows a downward opening parabola with a vertex at 3 comma 25, a point at negative 2 comma 0, a point at 8 comma 0, a point at 0 comma 16, and a point at 6 comma 16.
What is the standard form of the equation of f(x)?
f(x) = x2 − 6x + 16
f(x) = x2 + 6x + 16
f(x) = −x2 − 6x + 16
f(x) = −x2 + 6x + 16
Therefore, the equation of the parabola is:
f(x) = -(x - 3)² + 25
f(x) = -x² + 6x + 16
So the answer is f(x) = -x² + 6x + 16.
What does a vertex in mathematics mean?Typically, the intersection of two or more lines or edges forms a vertex, a singular point on a mathematical object. Graphs, polygons, polyhedra, and angles are the shapes that contain vertices most commonly. Nodes are another name for vertices in a graph.
Since the vertex of the parabola is at (3, 25), we know that the equation of the parabola is of the form:
f(x) = a(x - 3)² + 25
where "a" is a constant that determines the shape of the parabola. We also know that the parabola passes through the points (-2, 0), (8, 0), (0, 16), and (6, 16).
Let's plug in the coordinates of one of the points on the parabola to find the value of "a". For example, if we plug in the coordinates of the point (0, 16), we get:
16 = a(0 - 3)² + 25
-9 = 9a
a = -1
Therefore, the equation of the parabola is:
f(x) = -(x - 3)² + 25
f(x) = -x² + 6x + 16
So the answer is f(x) = -x² + 6x + 16.

Fill in the blank so that the ordered pair is a solution of y=22−9x
.
One possible ordered pair that is a solution of the equation y = 22 - 9x is (2, 4).
What is an ordered pair, and how can we find solutions of a linear equation?
An ordered pair is a pair of numbers (x, y) that represents a point on a coordinate plane. In algebra, we often use ordered pairs to represent solutions of equations, where the x-coordinate represents a variable and the y-coordinate represents the corresponding value of the expression.
To find solutions of a linear equation, we can substitute different values of the variable into the equation and solve for the corresponding values of the expression.
Find the ordered pair:
We are given the equation y = 22 - 9x, and we want to find an ordered pair that is a solution of the equation. To do this, we can choose a value of x and then use the equation to find the corresponding value of y.
Let's choose x = 2. Then, we can substitute x = 2 into the equation and solve for y:
y = 22 - 9(2)
y = 22 - 18
y = 4
Therefore, when x = 2, y = 4, which means the ordered pair (2, 4) is a solution of the equation.
We could also check this by graphing the equation and verifying that the point (2, 4) lies on the line represented by the equation.

Mr. and Mrs. Doran have a genetic history such that the probability that a child being born to them with a certain trait is 0.82. If they have four children, what is the probability that exactly two of their four children will have that trait? Round your answer to the nearest thousandth.
Using binomial distribution, the probability of exactly two of their four children having the trait is 0.13 (rounded to the nearest thousandth).
What is the probability that a child born to them with a certain trait is 0.82This is a binomial distribution problem with n = 4 trials (number of children) and p = 0.82 probability of success (having the trait) for each trial.
The probability of exactly two children having the trait can be calculated using the binomial distribution formula:
P(X = 2) = (4C2) * 0.82^2 * (1 - 0.82)^(4-2)
where (4C 2) is the number of ways to choose 2 children out of 4.
Using a calculator or statistical software, we get:
P(X = 2) = (4 C 2) * 0.82^2 * (1 - 0.82)^(4-2)
= 6 * 0.82^2 * 0.18^2
= 0.13

The width of Aubrey's bed is 40 inches and the distance between opposite corners is 85 inches. What is the length of Aubrey's bed?
Answer: 75 inches
Step-by-step explanation:
Using Pythagorean's Theorem, a² + b² = c², let a represent the length of the bed.
a² + 40² = 85²
a² + 1600 = 7225
a² = 5625
a = 75
The length of the bed is 75 inches.
Hope this helps!
Answer: 75
Step-by-step explanation: We can think of Aubrey’s bed as a triangle, Since the area doesn't matter. The base would be width (40) and the hypotenuse (length from corners) would be 85. So, since A^2+B^2=C^2 and c is 85 and a is 40. The equation is 40^2+?^2=85^2 so if we solve the numbers whit exponents we would get this: 1600+?=7225. Then we would just subtract 1600 from 7225 which is: 5625. Now we are not done. 5625 is just the square version of 5625. So we would need to find the square root. Which is 75.

Evaluate the integral by changing to cylindrical coordinates. 7 −7 49 − y2 − 49 − y2 11 xz dz dx dy x2 + y2
The value of the triple integral is 49π ln(49) - 24.5π.
To evaluate this triple integral using cylindrical coordinates, we need to express the limits of integration in terms of cylindrical coordinates. We can convert the Cartesian coordinates to cylindrical coordinates as follows:
x = r cos(θ)
y = r sin(θ)
z = z
The region of integration is a cylinder centered at the origin with radius 7 and height 14 (from -7 to 7 in the y-direction). Therefore, the limits of integration are:
0 ≤ r ≤ 7
0 ≤ θ ≤ 2π
-7 ≤ z ≤ 7
Substituting these limits of integration and the Cartesian-to-cylindrical conversion into the integral, we get:
∫∫∫ 7 −7 (49 - [tex]y^2 - r^2[/tex]) / ([tex]x^2 + y^2)[/tex] dz dx dy
= ∫[tex]0^7[/tex]∫[tex]0^2π[/tex] ∫-7^7 (49 - [tex]r^2[/tex]sin^2(θ) - r^2) / (r^2cos^2(θ) + r^2sin^2(θ)) dz r dθ dr
= ∫0^7 ∫0^2π ∫-7^7 (49 - r^2) / r^2 dz r dθ dr
= ∫0^7 ∫0^2π [ln|49-r^2|] from -7 to 7 dθ dr
= ∫0^7 2π ln|49-r^2| dr
This integral is now a single-variable integral that can be evaluated using integration by substitution or by parts. Let u = 49 - r^2 and du = -2r dr. Then:
∫0^7 2π[tex]ln|49-r^2|[/tex] dr = ∫49^0 -πln|u| du/-2
= π/2 [u ln|u| - u] from 49 to 0

does anyone know the answer?!?
Step-by-step explanation:
Lets find the slope of the line first so we can write the equation.
Counting the slope, we can see the slope of the line is [tex]\frac{3}{1}[/tex] or 3, so we have to write the equation of the line in slope intercept form [tex]y=mx+b[/tex] where m is the slope and b is the y intercept.
We know that the y intercept is -4 by looking at the graph, so we simply plug in our slope and y intercept.
[tex]y=3x-4[/tex]
To tell if equations are parallel or perpendicular:
Parallel: The slope is the same
Perpendicular: The slope is the opposite reciprocal
Lets look at the equations and see if there parallel:
1. [tex]y=-3x+10[/tex] is neither.
2. The equation of the line is in point slope form, however we are already given the slope in the equation. The slope is [tex]-\frac{1}{3}[/tex], which is the opposite reciprocal of 3, therefore it is perpendicular.
3. [tex]\frac{1}{3}[/tex] is not the opposite reciprocal of 3, it is neither.
4. The equation of the line is in standard form, which means we must solve for y to get it in slope intercept form
[tex]-3x+y=1[/tex]
Subtract -3x on both sides
[tex]y=1-(-3x)[/tex]
Simplify
[tex]y=3x+1[/tex]
The equation has the same slope, so it is parallel.

The steepest road in the world is Canton Avenue in Pittsburgh, Pennsylvania, with a grade of 37%. Grade is defined as the amount of vertical rise (in ft) over 100 ft of horizontal distance (so a road that rises 6 ft over 100 ft of horizontal distance is 6 100 = .06 = 6%). If the 37% grade of Canton Avenue goes for 21 ft of horizontal distance, how much does it rise? What angle does this grade make with the ground?
The steepest road in the world, Canton Avenue in Pittsburgh, Pennsylvania, has a grade of 37%. This means that for every 100 ft of horizontal distance, the road rises 37 ft. To find out how much the road rises for 21 ft of horizontal distance, we can use the formula:
rise = grade × distance
Plugging in the values we have:
rise = 0.37 × 21
rise = 7.77 ft
Therefore, the road rises 7.77 ft for 21 ft of horizontal distance.
To find the angle that this grade makes with the ground, we can use the formula:
tan θ = rise ÷ distance
Plugging in the values we have:
tan θ = 7.77 ÷ 21
tan θ = 0.37
θ = tan^-1(0.37)
θ = 20.3°
Therefore, the grade of Canton Avenue makes an angle of 20.3° with the ground.

Consider the sequence n an o[infinity] n=1 = n√ 2, q 2 + √ 2, r 2 + q 2 + √ 2, s 2 + r 2 + q 2 + √ 2, · · · o . Notice that this sequence can be recursively defined by a1 = √ 2, and an+1 = √ 2 + an for all n ≥ 1.
(a) Show that the above sequence is monotonically increasing. Hint: You can use induction.
(b) Show that the above sequence is bounded above by 3. Hint: You can use induction.
(c) Apply the Monotonic Sequence Theorem to show that limn→[infinity] an exists.
(d) Find limn→[infinity] an.
(e) Determine whether the series X[infinity] n=1 an is convergent
(a) By help of induction, it is proved the sequence is monotonically increasing for all n ≥ 1.
(b) The sequence is bounded above by 3 for all n ≥ 1.
(c) Applying the Monotonic Sequence Theorem, it is proved that the limit of the sequence exists.
(d) limn→[infinity] an is 2.
(e) The series X[infinity] n=1 an is convergent
(a) To show that the sequence is monotonically increasing, we can use induction. Let's first consider the base case, n = 1. We have a1 = √2 and a2 = √2 + a1 = √2 + √2 > a1, so the sequence is increasing for n = 1. Now, let's assume that the sequence is increasing for n = k, so ak+1 > ak. Then, for n = k+1, we have ak+2 = √2 + ak+1 > √2 + ak = ak+1, so the sequence is also increasing for n = k+1. Therefore, by induction, the sequence is monotonically increasing for all n ≥ 1.
(b) To show that the sequence is bounded above by 3, we can also use induction. Let's first consider the base case, n = 1. We have a1 = √2 < 3, so the sequence is bounded above by 3 for n = 1. Now, let's assume that the sequence is bounded above by 3 for n = k, so ak < 3. Then, for n = k+1, we have ak+1 = √2 + ak < √2 + 3 = 3.2 < 3, so the sequence is also bounded above by 3 for n = k+1. Therefore, by induction, the sequence is bounded above by 3 for all n ≥ 1.
(c) By the Monotonic Sequence Theorem, if a sequence is both monotonically increasing and bounded above, then the limit of the sequence exists. Since we have shown that the sequence is monotonically increasing in part (a) and bounded above by 3 in part (b), we can conclude that the limit of the sequence exists.
(d) To find the limit of the sequence, we can use the fact that an+1 = √2 + an for all n ≥ 1. Taking the limit of both sides as n approaches infinity, we get limn→∞ an+1 = limn→∞ √2 + an. Since the limit of the sequence exists, we can write this as L = √2 + L, where L is the limit of the sequence. Solving for L, we get L = 2, so the limit of the sequence is 2.
(e) To determine whether the series X∞ n=1 an is convergent, we can use the fact that the limit of the sequence is 2. Since the sequence converges to 2, the terms of the sequence are getting closer and closer to 2 as n approaches infinity. This means that the terms of the series are getting smaller and smaller, and the series is convergent.

and the price of bolts, b, is $2.39/b.
PartA Write an expression to represent the
total price of the supplies.
PartB What is the total cost of buying 2 pounds of nails, 4 pounds of
washers, and 3 pounds of bolts
Th expression for total price of the supplies is $ 12.91 .
What is Expression ?Any mathematical statement with variables, numbers, and an arithmetic operation between them is called an expression or an algebraic expression. For instance, the expression 4m + 5 has the terms 4m and 5 as well as the variable m of the supplied expression, all of which are separated by the arithmetic sign +.
Anything that is variable, or without a fixed value, is a variable. Alphabetic characters like a, b, c, m, n, p, x, y, z, and so on are typically used to denote expression variables. By combining several variables and numbers, we can create a wide range of expressions.
Given : price of nails, n = $1.29/b
price of washers, w = $0.79/b
price of bolts, b = $2.39/b
He bought 2 pounds of nails, 4 pounds of washers, and 3 pounds of bolts.

Convert the following phrase into a mathematical expression. Use x as the variable, and combine like terms.
Eight times a number added to −7, subtracted from triple the sum of four times the number and 7
The expression is ____.
Answer:
3(4x + 7) - (8x - 7)
Step-by-step explanation:
Place an inequality symbol between each fraction pair. State reasoning or rationale. (8)/(9),(10)/(12) -(5)/(6),-(6)/(8) Circle fractions that are completely simplified. State how this was determined.
No common factors
For the first set of fractions, the inequality symbol would be <, as 8/9 is less than 10/12. The rationale for this is that when fractions have different denominators, the fraction with the smaller denominator is always less. For the second set of fractions, the inequality symbol would be >, as -5/6 is greater than -6/8. The rationale for this is that when two fractions have the same denominator, the fraction with the larger numerator is always greater. The fractions that are completely simplified are 8/9, -5/6, and -6/8. This is because they cannot be reduced any further as they have no common factors.
