Answer:
The given equation is in vertex form y = a(x - h)^2 + k, where (h, k) is the vertex of the parabola. Comparing the given equation with the vertex form, we have a = -3, h = -3 and k = 4.
Since a = -3 < 0, the parabola opens downwards and has a maximum point.
To find the maximum value of y, we need to evaluate y at the x-coordinate of the vertex:
x = -3
y = -3(-3+3)^2 + 4 = 4
Therefore, the parabola y = -3(x+3)2 + 4 contains a maximum point and the maximum value of y is 4.
Hence, the answer is option C
Answer:
C) Maximum point; 4
Step-by-step explanation:
Given parabola:
[tex]y=-3(x+3)^2+4[/tex]
The given parabola is in vertex form:
[tex]\boxed{y = a(x - h)^2 + k}[/tex]
where:
(h, k) is the vertex of the parabola.a is the leading coefficient.If a > 0, the parabola opens upwards.
If a < 0, the parabola opens downwards.
By comparing the given equation with the vertex form, we can see that:
a = -3h = -3k = 4As a < 0, the parabola opens downwards. Therefore, the vertex of the parabola is a maximum point.
The vertex of the parabola is (h, k) = (-3, 4).
Therefore, the maximum value of y is 4, which occurs at x = -3.

The rate at which the surface area of the balloon is increasing at the instant the area is 153.24 square inches and the volume is 178.37 cubic inches is 4.96 square inches per second.
The surface area of a spherical balloon and the volume of the balloon are related by the equation [tex]A³ - 36πV²[/tex], where A is in square inches and V is in cubic inches. To find the rate at which the surface area of the balloon is increasing, we can use derivatives. We start by taking the derivative of the equation [tex]A³ - 36πV²[/tex] with respect to time (t).
[tex]d/dt[A³ - 36πV²] = 3A²dA/dt - 72πVdV/dt[/tex]

She has 4 times as many $20 bills as $10 bills. She has 3 times as many $1 bills as $20 bills. She has a total of $204.
Please I need help answering it in 20 minutes
Answers
Ann has 60 $1 bills, 5 $10 bills, and 20 $20 bills.
Let's assume Ann has $1x, $10y, and $20z bills.
From the given information, we can write two equations based on the relationships between the numbers of bills:
z = 4y (Ann has four times as many $20 bills as $10 bills)
x = 3z (Ann has three times as many $1 bills as $20 bills)
We know that the total amount of money Ann has is $204, so we can write a third equation:
x + 10y + 20z = 204
Now we can use substitution method here, substitute equation 2 into equation 1 to get:
z = 4y
x = 3z
x = 3(4y) = 12y
Substituting these equations into equation 3, we get:
12y + 10y + 20(4y) = 204
42y = 204
y = 4.86
Since y must be a whole number (representing the number of $10 bills), we can round up to y = 5.
Using equation 1, we can find that z = 4y = 20 (representing the number of $20 bills).
Using equation 2, we can find that x = 3z = 60 (representing the number of $1 bills).

Answers
Denote by X the arrival time of the first guest. The time of arrival of the first guest at a bank is modeled by the Poisson distribution, where the arrival rate is λ. Thus, the number of arrivals during time t is Poisson(λt).
Therefore, the distribution of X is Exponential(λ), which means that its probability density function is
f(x) = λe−λx, x > 0.
The expected value of X is E[X] = 1/λ and the variance is Var(X) = 1/λ².
b. Denote by Y the arrival time of the second guest.
The number of arrivals during time t is Poisson(λt). The first guest arrived at time X, so the number of arrivals from time X to time t is Poisson(λ(t - X)).
Thus, the arrival time of the second guest has the conditional probability density function:
f(y | X) = λe^(−λ(y−x)), y > x
Therefore, the unconditional probability density function of Y is obtained through the law of total probability:
f(y) = ∫f(y | x)f(x)dx
= ∫λe^(−λ(y−x))λe^(−λx)dx
= λ²e^(−λy), y > 0
Therefore, the distribution of Y is Exponential(λ), which is the same as that of X.

Answers
The price after discount is $33 and option 1 is the correct answer.
What is a discount?A discount is a drop in a product's or service's price. Discounts can be provided for a variety of purposes, such as to entice consumers to make larger purchases, to get rid of excess inventory, or to draw in new clients. Discounts can be represented as a set monetary amount or as a %, as in the example above. For instance, a shop may give customers $10 off any purchase of more than $50.
Given that, one-day discount rate of 45% is applied.
Thus,
Discount = 60.20 * 0.45 = 27.09
Price after discount = 60.20 - 27.09 = 33.11
Hence, the price after discount is $33 and option 1 is the correct answer.

Suppose a large candy machine has 45% orange candies. Imagine taking an SRS of 25 candies from the machine and observing the sample proportion
pof orange candies. Find the standard deviation of the sampling distribution of
pCheck to see if the 10% condition is met.
Answers
The standard deviation of the sampling distribution of pCheck to see if the 10% condition is 0.44.
If a large candy machine has 45% orange candies, and an SRS of 25 candies is taken from it, then the 10% condition can be checked to see if it is met. To do this, it is necessary to calculate the sample proportion p. To calculate p, the number of orange candies in the sample (let's call it x) is divided by the total number of candies in the sample (25). Thus, p = x/25. The 10% condition is met if the value of p is less than or equal to 0.1 (10%).
Since the value of p is unknown, the number of orange candies in the sample must first be determined. To find this number, the proportion of orange candies in the entire candy machine must be used. The proportion of orange candies is 45%, or 0.45.
This means that for every 100 candies in the candy machine, 45 are orange. Since there are 25 candies in the sample, 0.45*25 = 11.25 orange candies are expected in the sample. Since this is a sample proportion, the exact value of x must be rounded to the nearest whole number. This gives a value of 11 orange candies in the sample.
Now that the value of x is known, the value of p can be calculated. This gives p = 11/25 = 0.44.
Since 0.44 is greater than 0.1 (10%), the 10% condition is not met in this case.

we can use the notation P(A) and apply the definition of probability: P(A) = P(B), P (A ∩ B), and P (A ∪ B) if we have the necessary information.
What is Vann diagram?I believe you meant to say, "Venn diagram". A Venn diagram is a type of graphical representation used to illustrate relationships between sets or groups of objects, concepts, or ideas. It consists of a series of overlapping circles or other closed shapes, with each circle representing a set or group and the overlapping areas representing the relationships or intersections between them.
by the question.
Let A be the event that a student is a cast member of Seussical, and let B be the event that a student is a cast member of Wizard of Oz. Then, we can define the following:
A ∩ B: The event that a student is a cast member of both Seussical and Wizard of Oz.
A ∪ B: The event that a student is a cast member of either Seussical, Wizard of Oz, or both.
A': The event that a student is not a cast member of Seussical.
B': The event that a student is not a cast member of Wizard of Oz.
Based on the information given, we do not know how many students are in each of these events, but we can still make some general observations. For example:
If A and B have no students in common (i.e., A ∩ B = ∅), then the number of students in A ∪ B is equal to the sum of the number of students in A and the number of students in B.
If some students are in both A and B (i.e., A ∩ B is not empty), then the number of students in A ∪ B is equal to the sum of the number of students in A, the number of students in B, and the number of students in A ∩ B. In other words, some students are counted twice when we add up the number of students in A and the number of students in B, so we need to subtract the number of students in A ∩ B to avoid double-counting.
We do not know whether the events A and B are mutually exclusive (i.e., whether A ∩ B = ∅) or not. If they are mutually exclusive, then P(A ∩ B) = 0, and we can use the addition rule of probability to find P (A ∪ B) = P(A) + P(B). If they are not mutually exclusive, then we need to use the general addition rule of probability: P(A ∪ B) = P(A) + P(B) - P(A ∩ B).

The value of X is 42.5 and Y is 90.98.
How to solve equations?
To solve an equation, you need to perform the same operation on both sides of the equation until you isolate the variable on one side and have a numerical value on the other side. The process of solving an equation generally involves the following steps:
Simplify both sides of the equation by combining like terms and following the order of operations.
Add or subtract the same value from both sides of the equation to isolate the variable term.
Multiply or divide both sides of the equation by the same non-zero value to isolate the variable term.
Check your solution by plugging it back into the original equation and verifying that it satisfies the equation.
Solving the given equations :
To solve for X, we can use inverse operations to isolate the variable. Since 10 is multiplied by X, we can use the inverse operation of division by 10 to isolate X. So, dividing both sides of the equation by 10 gives:
[tex]10x/10 = 425/10[/tex]
Simplifying the left side of the equation gives:
[tex]x = 42.5[/tex]

Answers
The z-score for Keenan is 0.71, rounded up to the hundredth.
The Z-score determines the standard deviations by which the measure deviates from the mean. After calculating the Z-score, we look at the z-score table to ascertain the p-value associated with it. This p-value represents the percentile of X or the probability that the measure's value is smaller than X. You may get the likelihood that the value of the measure is greater than X by subtracting 1 from the p-value.
The formula for calculating the z-score is as follows: The z-score is the number of standard deviations an individual's score deviates from the mean.
z = (x - μ) / σ
where the mean score is, the standard deviation is, and x is the individual's score.

The cylinder below has a curved surface area of 408πm² and a length of 17 m.
Work out the total surface area of the cylinder.
Answers
Answer: The total surface area of the cylinder is 850π m².
Step-by-step explanation:
The cylinder has a curved surface area of 408π m², which is the area of the lateral surface of the cylinder. The lateral surface of a cylinder is the curved surface that connects the top and bottom bases of the cylinder.
The formula for the lateral surface area of a cylinder is given by: Lateral Surface Area = 2πrh, where r is the radius of the cylinder and h is the height (or length) of the cylinder.
We are given that the length of the cylinder is 17 m. Since the length of a cylinder is the same as its height, we can substitute h = 17 m into the formula for the lateral surface area to get:
408π m² = 2πr(17 m)
Simplifying this equation, we get:
r = 12 m
Now that we know the radius of the cylinder, we can find the total surface area of the cylinder. The formula for the total surface area of a cylinder is given by:
Total Surface Area = 2πr(r + h)
Substituting r = 12 m and h = 17 m into this formula, we get:
Total Surface Area = 2π(12 m)(12 m + 17 m) = 850π m²
Therefore, the total surface area of the cylinder is 850π m².

Answers
The simplified polynomial, with each term written in standard form, is: 36a^3b - 6a^2b^3 + 11a^2b
How to simplify the polynomialTo simplify the given polynomial, we need to expand and combine like terms.
First, we can distribute the coefficients of the first term:
12a^2 · 3ba = 36a^3b
Next, we can simplify the second term by multiplying the coefficients and adding the exponents:
-2ab · 3ab^2 = -6a^2b^3
Finally, we can combine the like terms:
36a^3b - 6a^2b^3 + 11a^2b
To write each term in standard form, we arrange the terms in decreasing order of exponents of 'a' and 'b':
36a^3b - 6a^2b^3 + 11a^2b
So, the simplified polynomial, with each term written in standard form, is:
36a^3b - 6a^2b^3 + 11a^2b

Cómo resolver este ejercicio de ecuaciones lineales de dos puntos

The equation m = 12 + 2Y1 gives the slope of the line through the points P1=(-1.5, Y1) and P2=(-2, -6)
In mathematics, how do you find coordinates?To find a point's coordinates in a coordinate system, you perform the opposite. Starting at the point, move vertically up or down until you reach the x-axis. Your x-coordinate is shown there. Afterwards, you'll be able to get a better understanding of how to use it.
It is assumed that the formula you supplied would be used to determine the slope (m) of the line connecting the two specified points, P1 and P2.
We may use the following formula to find the slope (m) of the line passing through the coordinates P1=(X1, Y1) and P2=(X2, Y2):m = (Y2 - Y1) / (X2 - X1) (X2 - X1)
Using the values provided:
P1 = (-1.5, Y1) (-1.5, Y1)
P2 = (-2, -6) (-2, -6)
These values can be used as substitutes in the formula:
m = (-6 - Y1) / (-2 - (-1.5))
Making the denominator simpler:
m = (-6 - Y1) / (-2 + 1.5)
m = (-6 - Y1) / (-0.5)
m = 12 + 2Y1

Answer:
Y=x^2+7x-3
complete the square to re-write the quadratic function in vertex form.
pls help
Step-by-step explanation:
To complete the square, we need to add and subtract a constant term inside the parentheses, which when combined with the quadratic term will give us a perfect square trinomial.
y = x^2 + 7x - 3
y = (x^2 + 7x + ?) - ? - 3 (adding and subtracting the same constant)
y = (x^2 + 7x + (7/2)^2) - (7/2)^2 - 3 (the constant we need to add is half of the coefficient of the x-term squared)
y = (x + 7/2)^2 - 49/4 - 3
y = (x + 7/2)^2 - 61/4
So the quadratic function in vertex form is y = (x + 7/2)^2 - 61/4, which has a vertex at (-7/2, -61/4).

The beam is 7.8 feet far away from the base of the house
How to determine how far away from the base of the house is the beam?Trigonometry deals with the relationship between the ratios of the sides of a right-angled triangle with its angles.
It involves the use of trigonometric functions such as sine, cosine and tangent.
Using the attached image:
Let b represent the distance from the base of the house to the beam. We can say:
cos 71° = b/24 (adjacent/hypotenuse)
b = 24 * cos 71°
b = 7.8 feet
