Answer:

Center : (-2, 7)

Radius : 6

Step-by-step explanation:

If you use desmos (graphing website), you're able to plug in the the equation to find the radius and center.

The largest area of the rectangle is 2 square units.

We have a right angled isosceles triangle with hypotenuse 4 units.

so its base will be equal to the perpendicular  , let it be B

So we know ,

B² + P² = H²

2B² = H²

B²  = 16/2

B = 2√2

So base is equal to perpendicular = 2√2 units

Now let consider a rectangle inside the triangle with length 2x and the width y , and the area will become

A = 2xy  ....(1)

we see from the figure the length of the perpendicular AD drawn on the hypotenuse is

BD² + AD² = AB²

AD² = AB² - BD²

      = 8 - 4

AD² = 4

AD = 2 units

Now we see triangle ABD and AEG are similar to each other , So

AD/BD = AG/GE

2/2 = 2-y/x

therefore

x = 2-y

put this value in eqn (1)

A = 2(2-y)y

A = 4y - 2y²

Now to maximize the area we take the derivative of the equation and then put it equal to zero

∴ 4 - 4y = 0

y = 1

∴ x = 2-y = 2-1 = 1 units

So area will be maximum when length and width are 1 units each.

therefore , largest area (A) of the rectangle is  = 2xy = 2 square units.

The problem with this measure is that it suffers from recall bias.

The measure used in the survey is problematic because of recall bias. This is when people's memories of past events are influenced by their current knowledge, opinions, or beliefs. In this case, the respondents may have reported consuming different amounts of alcohol in college in the two surveys due to changes in their attitudes or social pressures, which can affect their recollection. Therefore, the results of this survey may not be accurate and should be approached with caution when interpreting.

we will have to follow given below steps if we want to plot this inequality x is less than or equal to 2.6.

A linear inequality is formed by any two real numbers or any two algebraic expressions marked by the symbols "," ">," "," or "." Ones of numerical inequality include 911 and 18>17, while algebraic examples include x+7>y, y10-x, and x y > 11

One of the inequality symbols is present in a linear inequality:. It displays non-equal data in graph style. With the inequality sign in place of the equality sign, a linear inequality appears exactly like a linear equation.

The values of x that satisfy the inequality must be determined before we may graph the inequality x = 2.6 on a number line. This can be done by changing x to a variety of values and observing which ones cause the inequality to hold true. When x is less than or equal to 2.6, we know that the inequality x = 2.6 is true. This means that the inequality will be satisfied for any value of x that is lower than or equal to 2.6. This has a range of inclusive values from -infinity to 2.6. We can use a dotted line spanning from negative infinity to 2.6 to graph the inequality on a number line. We would insert a dot for each number between negative infinity and 2.6, including 2.6 itself, since the dots on the line denote the numbers in the range. The dots on the line represent the integers in the range, which spans from negative infinity to 2.6. (i.e., all numbers less than or equal to 2.6). The open circle at 3 shows that the number is outside of the range, while the solid point at 2.6 indicates that the number is within the range.

The probability of a car rolling over in a crash is approximately 0.016, or 1.6%, indicating that it is unlikely for a car to roll over in a crash.

We have,

To find the probability that a randomly selected passenger car crash results in a rollover, we divide the number of rollovers by the total number of crashes:

Probability of a rollover = Number of rollovers / Total number of crashes

Probability of a rollover = 83,600 / (83,600 + 5,127,400) ≈ 0.016

The probability of a rollover is approximately 0.016, or 1.6%.

Since the probability is relatively low, it can be considered unlikely for a car to roll over in a crash.

Thus,

Given: f(x) = x^2/ x-8We need to find the critical numbers, the intervals on which f(x) is increasing, the intervals on which f(x) is decreasing, and the local extrema. .Critical numbers: `x = 0, x = 16`Intervals of increasing: `(-∞, 0)`, `(8, ∞)`Intervals of decreasing: `(0, 8)`Local minima: `(0, 0)`Local maxima: `(16, 32)`

To find the critical numbers, the intervals on which f(x) is increasing, the intervals on which f(x) is decreasing, and the local extrema, we need to follow the steps below.Step 1: Find the derivative of f(x) using the quotient rule of differentiation.`f(x) = x^2/(x - 8)`Differentiating both the numerator and denominator we get: `f'(x) = [2x(x - 8) - x^2]/(x - 8)^2 = [-x^2 + 16x]/(x - 8)^2`Step 2: Find the critical numbers by setting `f'(x) = 0` and solving for x.`[-x^2 + 16x]/(x - 8)^2 = 0`We can see that the numerator will be zero when `x = 0 or x = 16`.But, since `(x - 8)^2 ≠ 0` for any real number x, we can ignore the denominator and we get two critical numbers: `x = 0` and `x = 16`.Step 3: Determine the intervals of increasing and decreasing of `f(x)` using the first derivative test.If `f'(x) > 0`, then `f(x)` is increasing.If `f'(x) < 0`, then `f(x)` is decreasing.If `f'(x) = 0`, then there is a local extrema at that point.The critical numbers divide the number line into three intervals: `(-∞, 0)`, `(0, 8)` and `(8, ∞)`.For `x < 0`, we can choose a test value of `-1` to get `f'(-1) > 0`, so `f(x)` is increasing on `(-∞, 0)`.For `0 < x < 8`, we can choose a test value of `1` to get `f'(1) < 0`, so `f(x)` is decreasing on `(0, 8)`.For `x > 8`, we can choose a test value of `9` to get `f'(9) > 0`, so `f(x)` is increasing on `(8, ∞)`.Step 4: Find the local extrema by finding the y-coordinate of each critical number.We need to substitute each critical number into the original function to find the y-coordinate.`f(0) = 0^2/(0 - 8) = 0``f(16) = 16^2/(16 - 8) = 256/8 = 32`Therefore, `f(x)` has a local minimum at `x = 0` and a local maximum at `x = 16`.

We have found the critical numbers, the intervals on which `f(x)` is increasing, the intervals on which `f(x)` is decreasing, and the local extrema of the function `f(x) = x^2/(x - 8)`.

Calories are needed to give you enough energy to move, keep warm, grow, work, think, and play. Our circulation and digestion also need to work well with the energy we get from calories.

Let x = calories in cookies.

     y = calories in carrots.

Now, according to the question:

     5x + 2y = 590                   --------------------------------------- (1)

     3x + 4y = 410                    -------------------------------------- (2)

Multiplying equation(1) by 3 and equation(2) by 5:

         15x + 6y = 1770                       ---------------------------(3)

         15x + 20y = 2050                   ---------------------------(4)

The balance of the account after 2.4 years is 975.22.

To find the balance of the account, we need to calculate the interest earned over 2.4 years and add it to the initial principal of 925.

The formula for simple interest is:

I = P × r × t

where:

I = interest earned

P = principal (initial amount of money)

r = annual interest rate (as a decimal)

t = time (in years)

Plugging in the values given in the problem, we get:

I = 925 × 0.023 × 2.4

I = 50.22

Therefore, the interest earned over 2.4 years is 50.22.

To find the balance of the account, we need to add the interest earned to the initial principal:

Balance = Principal + Interest

Balance = 925 + 50.22

Balance = 975.22

Answer:

The ticket is bought for 28 students.

Step-by-step explanation:

It is given that the teacher is going to buy museum ticket for each students.

Total money spent = $182

Price of each ticket = $6.50

Let total number of tickets bought = \(x\)

We know that to find the total amount of money spent on ticket, we can add price of each ticket (i.e. $6.50) \(x\) number of times.

OR

In other words, simply multiply the number of tickets with price of each ticket to find the total money spent.

Total money spent = \(x \times 6.50\)

We know that total money spent is $182.

\(\Rightarrow x \times 6.50 = 182\\\Rightarrow x = \dfrac{182}{6.50}\\\Rightarrow x = 28\)

The ticket is bought for 28 students

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.

The probability of an occurrence is a number between 0 and 1, with 1 representing certainty and 0 representing impossibility.

Since there are no other conceivable outcomes and the coin is fair, the odds of both the possibilities, "heads" and "tails," are equally likely to occur. As a result, the probability of either occurrence is half (which could also be written as 0.5)

Yes, people that taking part in an experiment are called variables.

There is normally one person called the dependent variable, and the other who is the independent variable.

The statement provided "people taking part in an experiment are called variables" is incorrect.

In an experiment, the individuals or subjects who participate and are observed or manipulated are not referred to as variables. Instead, they are called participants, subjects, or sometimes, respondents, depending on the context of the study.

Variables, on the other hand, are characteristics or properties that can vary or change among the individuals or subjects in the study. Variables can be classified as independent variables, dependent variables, or control variables.

Independent variables are manipulated or controlled by the researcher, while dependent variables are the outcomes or responses that are measured or observed.

Control variables are other factors that are held constant. Therefore, it is important to differentiate between the individuals participating in the experiment and the variables being studied.
