−−→AB=(xy)



What values should x and y take?
please answer

The equation that represents a line which is parallel to the y - axis would be B. x = −8.

When a line is parallel to the y - axis, this means that the line does not cross the y - axis in any way and is both vertical and straight because the y - axis is vertical and straight.

Any line that is parallel to the y - axis will need to be expressed in terms of terms of x because the y axis is expressed in terms of x as x = 0. From the options, the only equation expressed in terms of x is x  = -8. This line is therefore parallel to the y - axis.

Answer:

no pic or nothing but here is a number 324

Step-by-step explanation:

The sum of the given series is 72 / (72 + π^2).

We can use the formula for the sum of an infinite geometric series:

S = a / (1 - r)

where S is the sum, a is the first term, and r is the common ratio. In this case, the first term is (-1)^0 π^0 / (6^0 (2*0)!), which simplifies to 1, and the common ratio is (-1) π^2 / (6^2 (2*1)!), which simplifies to -π^2 / 72. Thus, we have:

S = 1 / (1 + π^2 / 72)

Now, we can simplify the denominator by multiplying the numerator and denominator by 72:

S = 72 / (72 + π^2)

Therefore, the sum of the given series is 72 / (72 + π^2).

Correct option is A, The foci of the hyperbola is (0,±√17).

A hyperbola is a plane curve that is produced by a point that is moving so that the difference between the distances from two fixed points is constant. It is created when a double right circular cone intersects with a plane that cuts through both ends of the cone.

The difference in distances between a group of points that are situated in a plane and two fixed points—which is a positive constant—is what is referred to as the hyperbola.

Given the equation of hyperbola is \(\frac{y^2}{12} - \frac{x^2}{5} = 1\)

In this equation,

a² = 12

b² = 5

Using the relation c² = a² + b²

c = √(12 + 5)

c = √ 17

As, the hyperbola is vertical,

The value of foci will be (0,±√17)

Answer:

l = 40 m

Step-by-step explanation:

The formula for area of a rectangle is

A = lw, where

Step 1:  Since we're given the area and width, we plug in these two values for A and w and to solve for l (length):

360 = 9l

Step 2:  Divide both sides by 9 to solve for l

(360 = 9l) / 9

40 m = l

Optional Step 3:  We can check our answers by checking that the product of 40 and 9 is 360

40 * 9 = 360

360 = 360

The four consecutive odd integers are -11, -9, -7, and -5.

Let's define the consecutive odd integers and set up an equation using the given conditions:
Let the four consecutive odd integers be:
x, x+2, x+4, x+6

The problem states that 5 times the sum of the first two is 5 less than 19 times the fourth:
5(x + (x+2)) = 19(x+6) - 5
Now, let's solve for x step-by-step:
Distribute the 5 and 19:
5(2x + 2) = 19x + 114 - 5
Simplify further:
10x + 10 = 19x + 109
Move all terms with x to one side by subtracting 10x from both sides:
10 = 9x + 109

Subtract 109 from both sides:
-99 = 9x
Divide by 9:
x = -11
Now that we have x, we can find the consecutive odd integers:
-11, -9, -7, -5.

Answer:

Q. 5 is: Dependent event Q. 7 is: $2

Step-by-step explanation:

The ratio between consecutive terms is (5^(n+1))/[(n+1)*(5^n)]. To find the ratio of the terms in the series, we need to determine the general term (an) of the series.

For the first series, ∑n=1∞ 5^n, we observe that each term is a power of 5. The general term can be expressed as an = 5^n.

For the second series, ∑n=1∞ 5^n/n, we have a combination of the terms 5^n and 1/n. The general term can be written as an = (5^n)/n.

To find the ratio between the terms, we'll calculate the ratio of consecutive terms:

Ratio = (a[n+1])/(an) = [(5^(n+1))/n+1] / [(5^n)/n]

Simplifying the expression, we can cancel out the common factors:

Ratio = (5^(n+1))/[(n+1)*(5^n)]

THE SHOWN EXPRESSION IS SHOWING THE DIFFERENCE BETWEEN THE SQUARE OF x+9 AND 4,SINCE THERE IS A MINUS SIGN INBETWEEN.

OPTION C IS THE ANSWER.

The probability that the selected contestant received a score of 5 55 on day 2 22 or day 3 33, given that the contestant received a score of 5 55 on one of the three days is 2/3 or approximately 0.67.

To see why, note that there are three possible cases: the contestant received a score of 5 55 on day 1 11, day 2 22, or day 3 33. We know that the contestant received a score of 5 55 on one of the days, so we can ignore the first case.

Now, since no contestant received the same score on two different days, the contestant who received a score of 5 55 on day 2 22 cannot have received that same score on day 3 33. Similarly, the contestant who received a score of 5 55 on day 3 33 cannot have received that same score on day 2 22. Therefore, if a contestant received a score of 5 55 on one of the days, there are only two possible days on which that could have happened (day 2 or day 3), and both of these have an equal chance of being the correct day. So, the probability is 2/3.

is a cognitive bias that refers to the tendency of individuals to interpret information in a way that confirms their pre-existing beliefs or hypotheses. It can lead to flawed conclusions because it disregards or discounts evidence that contradicts one's beliefs while selectively accepting information that supports them. This bias can occur in various contexts, including scientific research, data analysis, and

decision-making processes

. When confirmation bias is present, it can hinder objectivity and lead to biased interpretations or flawed conclusions based on incomplete or skewed information. It is important to be aware of this bias and strive for impartiality and open-mindedness when analyzing data or drawing conclusions.

Based on the given information, we can estimate that out of the total population of students, 2 out of 4 students (or 50%) own graphing TI calculators so it can be estimated that the proportion of students who do not own a TI graphing calculator is 50%.

To estimate the proportion of students who do not own a TI graphing calculator, we can use the information provided that out of the 4 students who owned a TI calculator, 2 had graphing calculators. Since we know that all graphing calculators are TI calculators, we can assume that the 2 students with graphing calculators are included in the total count of students who own TI calculators. Therefore, the remaining 2 students who own TI calculators must have non-graphing calculators.

Based on this information, we can estimate that out of the total population of students, 2 out of 4 students (or 50%) own non-graphing TI calculators. Therefore, we can estimate that the proportion of students who do not own a TI graphing calculator is 50%.

It's important to note that this is an estimation based on the limited information provided. To obtain a more accurate estimate, a larger sample size or more comprehensive data would be needed. Additionally, this estimation assumes that the sample of 4 students is representative of the entire student population in terms of calculator ownership. If there are any biases or limitations in the sampling method or if the sample is not representative, the estimate may not accurately reflect the true proportion of students who do not own a TI graphing calculator.

The diver's velocity during the first 2 sec of fall using the modified Euler method with Ar= 0.2 is 62.732 mph.

Given data: Initial velocity, u = 0 ft/sec

Acceleration, a = g = 32.2 ft/sec²

The maximum rate of fall, vmax = 80 mph

Time, t = 2 seconds

Air resistance constant, Ar = 0.2

We are supposed to determine the sky diver's velocity during the first 2 seconds of fall using the modified Euler method.

The governing equation for the velocity of the skydiver is given by the following:

ma = -m * g + k * v²

where, m = mass of the skydive

r, g = acceleration due to gravity, k = air resistance constant, and v = velocity of the skydiver.

The equation can be written as,

v' = -g + (k / m) * v²

Here, v' = dv/dt = acceleration

Hence, the modified Euler's formula for the velocity can be written as

v1 = v0 + h * v'0.5 * (v'0 + v'1)

where, v0 = 0 ft/sec, h = 2 sec, and v'0 = -g + (k / m) * v0² = -g = -32.2 ft/sec²

As the initial velocity of the skydiver is zero, we can write

v1 = 0 + 2 * (-32.2 + (0.2 / 68.956) * 0²)0.5 * (-32.2 + (-32.2 + (0.2 / 68.956) * 0.5² * (-32.2 + (-32.2 + (0.2 / 68.956) * 0²)))

v1 = 62.732 mph

Therefore, the skydiver's velocity during the first 2 seconds of fall using the modified Euler method with Ar= 0.2 is 62.732 mph.

Answer:

There are 2 solutions to square root x = 9

They are 3, and -3

Step-by-step explanation:

The square root of x=9 has 2 solutions,

The square root means, for a given number, (in our case 9) what number times itself equals the given number,

Or, squaring (i.e multiplying with itself) what number would give the given number,

so, we have to find the solutions to \(\sqrt{9}\)

since we know that,

\((3)(3) = 9\\and,\\(-3)(-3) = 9\)

hence if we square either 3 or -3, we get 9

Hence the solutions are 3, and -3

Equivalent equations are equations that have the same solution

The equation equivalent to \(-k + 0.03 + 1.01k = -2.45 - 1.81k\) is \(-100k + 3 + 101k = -245 - 181k\)\(-16+37i\)

The equation is given as:

\(-k + 0.03 + 1.01k = -2.45 - 1.81k\)

Collect like terms in the above equation

\(-k + 1.01k + 0.03 = -2.45 - 1.81k\)

Evaluate like terms

\(0.01k + 0.03 = -2.45 - 1.81k\)

Multiply through by 100 in the above equation

\(k + 3 = -245 - 181k\)

Express k as -100k + 101k

\(-100k + 101k + 3 = -245 - 181k\)

Rewrite as:

\(-100k + 3 + 101k = -245 - 181k\)

Hence, the equation equivalent to \(-k + 0.03 + 1.01k = -2.45 - 1.81k\) is \(-100k + 3 + 101k = -245 - 181k\)\(-16+37i\)

Answer:

Step-by-step explanation:

Answer:

\(x=32\)

Step-by-step explanation:

Given the equation:

\((x+2)+10=44\)

Begin by subtracting 10 from both sides of the equation:

\(x+2=34\)

Then, subtract 2 from both sides of the equation to find the value of \(x\):

\(x=32\)

-

You can check your answer by substituting the x-value into the initial equation:

\((32+2)+10=44\)

\(34+10=44\)

\(44=44\)

Since both sides of the equation are equal, our solution is correct.

Answer:

\( = > (x + 2) + 10 = 44\)

Subtracting 10 from both sides:

\( = > (x + 2) + 10 - 10 = 44 - 10\)

\( = > x + 2 = 34\)

Subtracting 2 from both sides:

\( = > x + 2 - 2 = 34 - 2\)

\( = > x = 32\)

Thus,the value of x is 32.

For checking:

\( = > (x + 2) + 10 = 44\)

Putting x=32

\( = >( 32 + 2) + 1 0= 44\)

\( = > 32 + 2 + 10 = 44\)

\( = > 34 + 10 = 44\)

\( = > 44 = 44\)
