Answer:
We can use a table of values or use a graphing calc.
Step-by-step explanation:
To find coordinates, we plug in random x-values to get y-value outputs.
We should get some points like (0, 0) and (1, 4) when we plug in numbers.
We then plot the points and draw a line.

VI. A dart is equally likely to land at any point inside a circle of radius 3 . Let R be the distance from the landing point to the origin. Find 1. P(R
Answers
The probability distribution function (pdf) of R follows a uniform distribution over the interval [0, 3]. Therefore, the probability of R being less than or equal to a specific value r is given by P(R ≤ r) = r/3.
The distance R from the landing point to the origin can take any value between 0 and 3 since the circle has a radius of 3. The probability of R falling within a certain range can be determined by calculating the proportion of the circle's area that corresponds to that range.
In this case, since R follows a uniform distribution, the pdf is constant over the interval [0, 3]. The area under the pdf curve is equal to 1, representing the total probability.
To find the probability of R being less than or equal to a specific value r, we calculate the ratio of the length of the interval [0, r] to the length of the entire interval [0, 3]. In this case, P(R ≤ r) = r/3.
For example, if we want to find the probability that R is less than or equal to 2, we plug in r = 2 into the formula: P(R ≤ 2) = 2/3 = 0.6667.
Therefore, the probability distribution of R in this scenario is a uniform distribution over the interval [0, 3], and the probability of R being less than or equal to a specific value r is given by P(R ≤ r) = r/3.

if the first table in a cartesian join has five rows and the second table has three rows, the results will consist of ____________________ rows.
Answers
In a Cartesian join, also known as a cross join, each row from the first table is combined with each row from the second table.
If the first table has 5 rows and the second table has 3 rows, the result of the Cartesian join will consist of 5 * 3 = 15 rows.
5sin(tetha)-r=6 cos(tetha) the equation in the cartesian coordinates is 5X-6 y=(x2 + y2)
5x+6y=(x2+ y2)) 5y+6 x=(x2 + y2)2 None of the others 5 y-6 x=(x2+y2)2
Answers
The equation 5y - 6x = (x^2 + y^2)^2 represents the equation in Cartesian coordinates corresponding to the given equation in polar coordinates, 5sin(theta) - r = 6cos(theta).
To convert the equation from polar coordinates to Cartesian coordinates, we substitute x = rcos(theta) and y = rsin(theta) into the given equation. After substitution, the equation becomes 5(rsin(theta)) - r = 6(rcos(theta)).
By simplifying the equation, we obtain 5y - 6x = (x^2 + y^2)^2, which represents the equation in Cartesian coordinates.
The equation (x^2 + y^2)^2 = 5y - 6x does not match the given equation. This equation is not obtained through the correct conversion from polar to Cartesian coordinates. Therefore, the correct answer is 5y - 6x = (x^2 + y^2)^2.

Which statement is true about vertical angles. 1 point Vertical angles are congruent if two lines are parallel. If vertical angles are congruent, then two lines are parallel. Vertical angles are always congruent. Vertical angles are supplementary if two lines are parallel.
Answers
Answer:
Vertical angles are always congruent.
Step-by-step explanation:
Vertical angles are formed when two straight lines intersect each other, thereby forming two pairs of opposite angles, which are called vertical angles. Thus, a pair of these vertical angles formed are congruent to each other. So therefore, if two angles are said to be vertical angles, it follows that they are congruent to each other.
Using the diagram attached below, we can see two straight lines intersecting each other to form two pairs of vertical angles:
<a and <b,
<c and <d.
Thus, <a is congruent to <b, and <c is congruent to <d.
Therefore, the standby that is true about vertical angles is that:
Vertical angles are always congruent.

Answer:
x = 90 degrees and y = 43 degrees
Step-by-step explanation:
We have an isosceles triangle here, since the length of AB equals the length of AC.
That also means that angle ABC equals angle ACD = 47 degrees.
The sum of the interior angles of a triangle equals 180.
47 + 47 + 2y = 180
94 + 2y = 180
2y = 86
y = 43 degrees
x + 43 + 47 = 180
x + 90 = 180
x = 90

Answers
To calculate the time it would take for an object to fall from the edge of the tabletop to the floor, we can use the y-direction displacement formula:
y = voy*t + (1/2)*ay*\(t^2\)
Where:
y = displacement (which is the height of the tabletop)
voy = initial velocity (which is 0 since the object is at rest initially)
ay = acceleration in the y-direction (which is the acceleration due to gravity, approximately -9.8 m/\(s^2\))
t = time
Since we are given the displacement (height of the tabletop), we can rearrange the formula and solve for t:
y = (1/2)*ay*\(t^2\)
Simplifying:
2y/ay =*\(t^2\)
Taking the square root of both sides:
t = sqrt(2y/ay)
Now, substitute the given values:
ay = -9.8 m/\(s^2\)) (acceleration due to gravity)
y = 0.52 m (displacement or height of the tabletop)
t = sqrt(2*0.52/-9.8)
Calculating the time:
t ≈ 0.323 seconds
Therefore, it would take approximately 0.323 seconds for any object to fall from the edge of the tabletop to the floor.

Today is Derek's 25th birthday. Derek has been advised that he needs to have $2,176,097.00 in his retirement account the day he turns 65 . He estimates his retirement account will pay 8.00% interest. Assume he chooses not to deposit anything today. Rather he chooses to make annual deposits into the retirement account starting on his 27.00 th birthday and ending on his 65th birthday. How much must those deposits be? Answer format: Currency: Round to: 2 decimal places.
Answers
To accumulate $2,176,097.00 in his retirement account by age 65, Derek needs to make annual deposits of $5,000.00 starting on his 27th birthday and ending on his 65th birthday, assuming an 8.00% interest rate.
To determine the annual deposits Derek needs to make, we can use the future value of an ordinary annuity formula. First, we calculate the number of years between Derek's 25th and 65th birthdays, which is 65 - 25 = 40 years. Next, we calculate the future value of the retirement account using the given interest rate of 8.00%. Using the formula:
Future Value = Present Value * (1 + interest rate)^number of periods
In this case, the future value is $2,176,097.00, the interest rate is 8.00%, and the number of periods is 40. We can rearrange the formula to solve for the present value:Present Value = Future Value / (1 + interest rate)^number of periods
Substituting the values:Present Value = $2,176,097.00 / (1 + 0.08)^40 = $123,529.31 (rounded to 2 decimal places)
Now, we need to find the annual deposit amount. Since Derek starts making deposits on his 27th birthday and ends on his 65th birthday, he makes deposits for 65 - 27 = 38 years.Annual Deposit = Present Value / ((1 + interest rate)^number of periods - 1)Substituting the values:
Annual Deposit = $123,529.31 / ((1 + 0.08)^38 - 1) = $5,000.00 (rounded to 2 decimal places)Therefore, Derek must make annual deposits of $5,000.00 into his retirement account starting on his 27th birthday and ending on his 65th birthday to accumulate $2,176,097.00 by the time he turns 65.
