The__________or_______a value of the function is found at the vortex.
Answer:
Step-by-step explanation:
n fluid dynamics, a vortex is a region in a fluid in which the flow revolves around an axis line, which may be straight or curved. Vortices form in stirred fluids, and may be observed in smoke rings, whirlpools in the wake of a boat, and the winds surrounding a tropical cyclone, tornado or dust devil. Vortices are a major component of turbulent flow. The distribution of velocity, vorticity, as well as the concept of circulation are used to characterise vortices. Hope that gave you a clue and hope you learned something new.
The minimum or maximum value of a function is found at the vertex.
The vertex represents either the minimum or maximum point on the graph of the function.
If the quadratic function opens upward, the vertex is the minimum point, and if it opens downward, the vertex is the maximum point.
The x-coordinate of the vertex can be found using the formula x = -b / (2a), where a, b, and c are the coefficients of the quadratic function in the form ax² + bx + c.
Once you find the x-coordinate, you can substitute it back into the function to obtain the corresponding y-coordinate, which represents the minimum or maximum value of the function at the vertex.

A sales tax of 7% was added to the $36.00 price of a jacket. What was the total cost of the jacket?
a. $36.70
b. $38.10
c. $36.07
d. $38.52
Answer:
[tex]\huge\boxed{\sf \$ \ 38.52}[/tex]
Step-by-step explanation:
Marked price = $36.00
Sales tax = 7%
Sales tax in $:= 7% of marked price
= 7% of $36 [Key: "of" means "to multiply"]
= 7/100 * 36
= 0.07 * 36
= $2.52
Selling price:= Marked price + sales tax
= $36 + $2.52
= $38.52
[tex]\rule[225]{225}{2}[/tex]
The total cost of the jacket was the amount of $38.52. The correct answer is option (d).
To find the total cost of the jacket after adding a 7% sales tax, we need to calculate the tax amount and add it to the original price.
Calculate the tax amount:
Tax amount = 7% of $36.00
Tax amount = 0.07 × $36.00
Tax amount = $2.52
Add the tax amount to the original price:
Total cost = $36.00 + $2.52
Total cost = $38.52
Thus, the total cost of the jacket was the amount of $38.52.
Hence, the correct answer is option (d).

5x = 24
x = 24/5 = 4/4/5
Hello!
5x : 9 = 8 : 3

Bobby is a freshman in high school and he just received $500 for graduation from middle school from his grandparents. he wants to save his $500 for college in 4 years if he deposits his $500 into a simple interest savings account for the next 4 years that has a rate of 2.85%. how much will he have in his account after 4 years?
Bobby will have $557 in his account after 4 years.
What is simple interest?Simple interest is calculated based on a loan's principal or the initial deposit into a savings account.
Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay further interest on the interest that has already accrued.
Simple interest = (principal amount×Rate of interest×time-period)/100
The principal amount deposited was $500.
The rate of interest given by the bank is 2.85%.
The duration of deposit is 4 years.
Simple interest = (500×2.85×4)/100
= 57
Simple interest given by the bank after 4 years is $57.
The total sum of money Bobby will have in his bank is $500 + $57 = $557.
Therefore, after 4 years Bobby will have $557 in his account.

Solve each triangle. Round answers to the nearest tenth.
Answer:
Step-by-step explanation:
a = 12 mi
b ≈ 14.0 mi
c = 7 mi
m∠A ≈ 59.0 °
m∠B ≈ 91°
m∠C ≈ 30.0 °
The lengths of the triangle are:
a = 12 mi
b ≈ 14.0 mi
c = 7 mi
And the angles of the triangle are :
m∠A ≈ 59.0°
m∠B ≈ 91°
m∠C ≈ 30.0°
What are the angles in a triangle?
Every triangle has interior angles that total 180.
Angles in a triangle are the total (sum) of the angles at each of its three vertices.
Given, in a triangle ∠B is = 91°
length of c = 7 mi
a = 12 mi
We need to find the missing angles and side length of b.
⇒ b² = a² ₊ c² ₋ 2accosB
⇒ b/sinB = a/sinA = c/sinC
b² = 12² ₊ 7² ₋ 2(12)(7)cos91°
b² = 144 ₊ 49 ₋ 2(84)cos91°
b² = 193 ₋ 168 cos 91°
b² = 195.856
b=√195.856
b = 14.0 mi
⇒14.0/sin91° = 12/sinA
⇒ sinA = 12sin91°/14.0
sin A = 0.857
A = arcsin(0.857)
A = 59.0°
∴ C = 180° ₋ (sum of two angles in a triangle)
C = 180 ₋ (91° ₊ 59°)
C = 180 ₋ 150°
C = 30°
Hence we get the angles in the triangle as m∠A = 59.0°, m∠B = 91° and m∠C = 30°

2. when f(x) = 2, x = -1
Step-by-step explanation:
We can't evaluate f(2) because we don't have f(x), if we did, we would plug in 2 for x.
On the other hand, solve f(x) = 2 asks for what x is equal to when f(x) = 2, f(x) is just the value on the y axis in relationship with x (in short terms, the value on the y axis).
So looking at the graph, we cam see that when x = -1, f(x) = 2.

What is the shaded portion of the figure?
Answer:
D
Step-by-step explanation:
Area of Part of a Circle = (θ/360)[tex]\pi r^{2}[/tex]
We first find the area of CAB first.
Radius of CAB = AB = 6cm
θ = 112
Area of CAB = [tex]\frac{112}{360} \pi (6)^{2} \\=\frac{56}{5} \pi cm^{2}[/tex]
Next we will find the area of FAE.
Radius of FAE = AE = 4cm
Area of FAE = [tex]\frac{112}{360} \pi (4)^{2} \\=\frac{224}{45} \pi cm^{2}[/tex]
Lastly,
Area of Shaded Region = Area of CAB - Area of FAE
= [tex]\frac{56}{5} \pi -\frac{224}{45}\pi \\=\frac{56}{9} \pi cm^{2}[/tex]
Therefore the answer is D.

A swimming pool is being filled with water. The diameter of the pool is 27 feet, and the height is 4 feet. Which formula best represents the volume of the pool?
V = pi (13.5) (4)

V = pi (27) (4)
V = pi (27) squared (4)
The expression that best represents the volume is (b) [tex]V = \pi (13.5)^2 (4)[/tex]
How to determine the volume?The given parameters are:
Diameter, d = 27
Height, h = 4

Let us first define what any of these terms mean.
The mean is found by adding all the numbers in the set, and dividing the sum by how many numbers are found in the set.
> Given set {5, 12, 6, 3, 8, 16, 8, 6}, the sum of the numbers is 5 + 12 + 6 + 3 + 8 + 16 + 8 + 6 = 64. 64 ÷ 2 = 32. Thus, the mean is 32.
The median is found by finding the number in the middle of the set, and dividing it by 2. This is easy in odd numbers as there is only one number in the middle that is the same amount of numbers left and right proportionally. However, in even numbers, there are two middles to be proportional. If it as an even number, then add the 2 middles together, and divide by 2.
> Given set {5, 12, 6, 3, 8, 16, 8, 6}, this set has an even number of numbers in the set. Thus, the middles are 3 and 8. 3 + 8 = 11, and 11 ÷ 2 = 5.5. Thus, the median is 5.5.
The mode is the number that most frequently appears in the set. In this case, we have 2 frequent numbers. That is 6 and 8. They both appear 2 times separately. Thus, 6 and 8 are the modes of this set.
The range is the difference (i.e subtraction) between the largest number on the set and the smallest number on the set.
> Given set {5, 12, 6, 3, 8, 16, 8, 6}, the range is 16-3 or 13. Thus, the range is 13.
Now that we have the definitions, we can compute the other set very easily.
> Given set {2, 7, 4, 11, 12, 4, 6}, the mean is 18.
> Given set {2, 7, 4, 11, 12, 4, 6}, the median is 5.5.
> Given set {2, 7, 4, 11, 12, 4, 6}, the mode is 4.
> Given set {2, 7, 4, 11, 12, 4, 6}, the range is 10.
