Which of the following graphs will
display the narrowest parabola?
y = -2x²+x+3
f(x) = -4x² - 30x
A graph that would display the narrowest parabola is f(x) = -4x² - 30x.
How to determine the equation of a parabola?In Mathematics, the standard equation of the directrix lines for any parabola can be modeled or represented by the following mathematical expression:
y = a(x - h)² + k.
Where:
h and k are the vertex.a represents the leading coefficient.Generally speaking, the larger the absolute value of the leading coefficient of a quadratic function, the narrower would be graph of its parabola.
In this context, we have the following:
y = -2x²+x+3; a = -2
f(x) = -4x² - 30x; a = -4
|a| = |-2| = 2
|a| = |-4| = 4
Therefore, |-2| is less than |-4|.

Answer:
population: 2,900,904.279
Step-by-step explanation:
You need to calculate the total area first. The figure is made from 2 smaller figures.
Area for the top figure = 159 x (345 - 276) = 159 x 69 = 10971
Area for the bottom figure = 265 x 276 = 73140
Total are = 10971 + 73140 = 84111 mi^2
so you have 34.489 people/mi^2 =>
34.489 x 84111 = 2,900,904.279 people
Liz spent her summer break working at Wild Lakes waterpark. At the end of the summer, she put $570 of her earnings into a savings account that earns 1% interest each year.
The total simple interest earned by Liz at the end of 5 years is found as: $28.5
Explain about the simple interest?A straightforward but effective idea. Very simply: interest is the benefit for saving - and the penalty of borrowing.
When you deposit funds into a savings account, you are paid interest, or additional money on top. The reason for this is that the bank gives you interest for letting them use your money.When someone owes money, they are assessed this fee. It indicates the time worth of money and is charged in relation to the principal sum. It is the prize for holding out and refusing to accept an early reward.Principal P = $570
Interest r = 1%
Time t = 5 years.
SI = P*R*t / 100
SI = 570*1*5 / 100
SI = 28.5
Thus, the total simple interest earned by Liz at the end of 5 years is found as: $28.5.

Answer: [tex]6\sqrt{2}[/tex]
Step-by-step explanation:
We know that one angle is 45 degrees and another is 90 degrees. That means the third angle is also 45 degrees, because all angles in a triangle add up to 180 degrees. This means that the triangle we are dealing with is an isosceles right triangle, meaning the the 2 equal legs form a right angle and are equal in length. If one leg is 6, the other leg must be 6, too.
Then, by the Pythagorean theorem, x=[tex]\sqrt{6^2+6^2}[/tex]=[tex]\sqrt{72}=6\sqrt{2}[/tex].
Olivia and Kalina are running a lemonade stand for one weekend. They sell lemonade for $0. 75
per cup. On Saturday, they sell 37 cups. For the weekend, they want to make at least $45. 00 in
sales on lemonade. Let c be the number of cups they sell Sunday,
If they sell 12 cups on Sunday will they reach their goal? Show this work on your paper and use it
to help you answer the next question. *
Yes, they will reach their goal of $45.00 by selling 12 cups of lemonade on Sunday.
Yes, they will reach their goal. To calculate this we can use the following formula:
Total Sales = (Number of cups sold on Saturday × Price per cup) + (Number of cups sold on Sunday × Price per cup)
Total Sales = (37 × 0.75) + (12 × 0.75)
Total Sales = 27.75 + 9
Total Sales = 36.75
Since 36.75 is greater than the goal of 45.00, they will reach their goal. This can be further verified by looking at the total cost of the cups they sold. 37 cups sold on Saturday at $0.75 each will cost $27.75. Adding the 12 cups sold on Sunday at $0.75 each will cost $9, bringing the total cost of the cups sold to $36.75. This is the same amount that was calculated using the formula above. Therefore, they will reach their goal by selling 12 cups of lemonade on Sunday.

Two polygons are similar if and only if there is a correspondence among their angles and among their sides so that all corresponding angles are congruent and all corresponding sides are proportional.
Two polygons are said to be similar if they have the same shape, but not the same size. A polygon is any two-dimensional closed shape with straight lines. Similar polygons have the same number of sides and angles. The sides of the similar polygons are proportional to the corresponding sides of the other polygon.
The ratio of their corresponding sides is the same as the ratio of their perimeter. The angles of the similar polygons are congruent to the corresponding angles of the other polygon. The ratio of their corresponding angles is the same as the ratio of their measure.
The corresponding sides and angles are the ones that match between the two polygons. In other words, they are the sides and angles that are in the same position in the two polygons. For example, side AB in polygon ABC corresponds to side DE in polygon DEF. Angle A in polygon ABC corresponds to angle D in polygon DEF.

Mariko is fencing her garden. She wants to use 50ft of fencing. Mariko also wants the sum of the length and the width of the garden to be 25ft. Use the system of equations to confirm that there are infinitely many possibilities for the length and width. Are there any limits to what values the length and width can be? explain your reasoning.
2L + 2W = 50
L + W = 25
We can use the system οf equatiοns tο sοlve fοr the length and width οf Marikο's garden. The first equatiοn represents the fact that the perimeter οf the garden, which is the sum οf the length and the width multiplied by twο, is equal tο 50 feet.
The secοnd equatiοn represents the fact that the sum οf the length and the width is equal tο 25 feet. We can sοlve this system οf equatiοns using substitutiοn οr eliminatiοn.
Using substitutiοn, we can sοlve fοr οne variable in terms οf the οther in the secοnd equatiοn:
L + W = 25
W = 25 - L
Nοw we can substitute this expressiοn fοr W intο the first equatiοn:
2L + 2W = 50
2L + 2(25 - L) = 50
Simplifying:

50 = 50
This equatiοn is true fοr any value οf L and W that satisfies the cοnditiοn that the sum οf the length and the width is equal tο 25 feet. Sο we have infinitely many pοssibilities fοr the length and width οf Marikο's garden.

(a) What is the probability that fewer than three calls will be received in the first 6 seconds?
The probability that fewer than three calls will be received in the first 6 seconds is 0.9197 or approximately 0.92.
Given:
The arrival of telephone calls at a switch can be modeled with a Poisson distribution.X is the number of calls that arrives in t minutes.Pr(X=k) = At^k/k! where A is the average arrival rate in calls/minute and k is the number of calls received.The average rate of calls is 10 per minute.We need to find the probability that fewer than three calls will be received in the first 6 seconds.Let's convert the given time period of 6 seconds into minutes, as our arrival rate is in calls per minute.
6 seconds = 6/60 minutes = 0.1 minutes
We are given that the average rate of calls is 10 per minute, which means that the arrival rate per 0.1 minute is:
A = 10/minute * 0.1 minute = 1 call
We need to find the probability that fewer than three calls will be received in 0.1 minutes. We can use the Poisson distribution formula to calculate this probability:
Pr(X < 3) = Pr(X=0) + Pr(X=1) + Pr(X=2)Pr(X=k) = At^k/k! , so
Pr(X=0) = e^(-A)*(A^0/0!) = e^(-1) = 0.3679
Pr(X=1) = e^(-A)*(A^1/1!) = e^(-1)*1 = 0.3679
Pr(X=2) = e^(-A)*(A^2/2!) = e^(-1)11/2 = 0.1839
Therefore,
Pr(X < 3) = 0.3679 + 0.3679 + 0.1839 = 0.9197
Hence, the probability that fewer than three calls will be received in the first 6 seconds is 0.9197 or approximately 0.92.

The expression that is used to find the x-coordinate of that midpoint is expressed as: [(x)1 + (x)2]/2, which denotes the average of the x-coordinates. Similarly, the expression that is used to find the y-coordinate of that midpoint is expressed as: [(y)1 + (y)2]/2, which is the average of the y-coordinates.
We are given the coordinates of the endpoints of the line as;
K(-11, 2) and L(-19, 6)
Thus;
Midpoint Coordinate = (-11 - 19)/2, (2 + 6)/2
= (-15, 4)

Para resolver la multiplicación 34 x 4 usando sumas repetidas, podemos seguir los siguientes pasos:
Empezamos sumando 34 cuatro veces:
34 + 34 + 34 + 34 = 136
La suma resultante de la etapa anterior es la respuesta, por lo que podemos concluir que:
34 x 4 = 136
Por lo tanto, hemos resuelto la multiplicación 34 x 4 usando sumas repetidas y obtenido la respuesta de 136.
A continuación, mostraremos otra forma de resolver el mismo problema utilizando la propiedad distributiva de la multiplicación.

Respuesta:
Para resolver la multiplicación 4 x (34) utilizando la propiedad distributiva, podemos seguir los siguientes pasos:
Dividimos el factor 34 en dos partes: 30 y 4/4.
Multiplicamos cada parte por el otro factor, 4:
4 x 30 = 120
4 x (4/4) = 4
Sumamos los resultados de las dos multiplicaciones:
120 + 4 = 124
Por lo tanto, hemos resuelto la multiplicación 4 x (34) utilizando la propiedad distributiva y obtenido la respuesta de 124.
En conclusión, aunque se pueden resolver de diferentes maneras, ambas formas nos llevan al mismo resultado.

Relation 2 and 3 are actual functions with proper domain, co domain, range.
Describe Function?A function can be represented in several ways, including using algebraic expressions, tables, graphs, or even words. For example, the function f(x) = 2x + 1 defines a relationship between the input x and the output 2x + 1. If we input x = 3 into this function, the output would be f(3) = 2(3) + 1 = 7.
Functions can have different properties, such as being continuous or discontinuous, being differentiable or nondifferentiable, or having maximum or minimum values. Functions can also be classified according to their types, such as linear, quadratic, exponential, logarithmic, trigonometric, or piecewise-defined functions.
Functions are used extensively in mathematics, science, engineering, economics, and many other fields to describe real-world phenomena and to solve practical problems. They are also studied in their own right, as objects of mathematical interest and beauty, with deep connections to many other areas of mathematics, such as calculus, analysis, and algebra
