Graph the circle with center (2, −3) that passes through (2, 0). Find the area in terms of π and to the nearest tenth. Use 3.14 for π.
Circle with center (2,-3) that passes through (2,0) has an area of 9π units² in terms of π and 28.3 units² (nearest tenth).
As given in the question,
Circle with center C(2, -3)
Passes through point A(2,0)
Graph of the circle attached.
Radius of the circle 'r'
r =CA
CA = √(2-2)² +(0+3)²
= √9
= 3
Area of the circle = πr²
= π (3)²
= 9π units² (in terms of π)
= 9 ×3.14
= 28.26
= 28.3 units²
Therefore, circle with center (2,-3) that passes through (2,0) has an area of 9π units² in terms of π and 28.3 units² (nearest tenth).

Events A and B are mutually exclusive. Suppose event A occurs with probability 0.23 and event B occurs with probability 0.21.
a. Compute the probability that A occurs but B does not occur.
b. Compute the probability that either A occurs without B occurring or B occurs without A occurring.
Using it's concept, the probabilities for this problem are given as follows:
a) A occurs and B does not: 0.1817 = 18.17%.
b) Either occurs: 0.3434 = 34.34%.
What is a probability?A probability is calculated as the number of desired outcomes in the experiment divided by the number of total outcomes in the experiment.
In the context of this problem, we have two mutually exclusive events, meaning that they cannot happen together.
For item a, we have that:
The probability of A occurring is 0.23.The probability of B not occurring is of 1 - 0.21 = 0.79.The events are mutually exclusive, hence we can multiply the probabilities as follows:
p = 0.23 x 0.79 = 0.1817 = 18.17%.
For item b, we add the probability in item with the probability of B occurring and A not, found as follows:
The probability of B occurring is 0.21.The probability of A not occurring is of 1 - 0.23 = 0.77.Hence:
p = 0.1817 + 0.21 x 0.77 = 0.3434 = 34.34%.

The volume of the figure shown in the reference attachment, provided hereby with the question statement will be 6786 ft³.
As per the question statement and the reference attachment, we are provided with a figure and its dimensions.
We are required to calculate the volume of the concerned figure using the dimensional values provided.
To solve this question, we need to calculate the volumes of the bottom cuboidal part, and the top pyramidal part separately, and then add these volumes, to obtain our final desired answer.
Given, the dimensions of the bottom cuboidal part is (21ft by 18ft by 13ft).
We know that, volume of a cuboid = (length * breadth * height).
Therefore, volume of our concerned bottom cuboidal part
= (21 * 18 * 13) ft³
= 4914 ft³.
Also given, the dimensions of the top pyramidal part are as follows,
Base of the triangle = 18 ft,
Altitude of the triangle = 16 ft,
and length of the pyramid = 13 ft.
Therefore, Volume of the concerned pyramid
= [(1/2) * base * altitude * length]
= [(1/2) * 18 * 16 * 13] ft³
= (9 * 16 * 13) ft³
= 1872 ft³.
Therefore, Total volume of the concerned figure shown in the reference attachment, provided hereby with the question statement will be
(4914 + 1872) ft³ = 6786 ft³

Draw the graph and find the equation of the hyperbola if the asymptotes are y=0.5x and y = −4−0.5x, and one of the vertices is (−4, 0).
The equation of the hyperbola is -(1/16) (x +4)² + (1/4) (y +2)² = 1
What is Hyperbola?
A hyperbola is a particular kind of smooth curve that lies in a plane and is classified by its geometric characteristics or by equations for which it is the solution set. A hyperbola is made up of two mirror images of one another that resemble two infinite bows. These two sections are known as connected components or branches.
The intersection of the two asymptotes is where the hyperbola's center is located. This is the key idea (-4,-2)
We have y orientation because the vertex at (-4,0) is above this location. The equation will take the form as a result.
-a (x + 4)
2 + b (y + 2)
In the case of certain a and b, 2 Equals 1.
Inputting (-4,0) reveals that b = 1/4.
Finally, requiring that y = x/2 be an asymptote reveals that a = 1/16.
-(1/16) (x +4)² + (1/4) (y +2)² = 1
Hence, The equation of hyperbola is -(1/16) (x +4)² + (1/4) (y +2)² = 1

The equation shown has a missing value.
-2(2x - _) + 1 = 17 - 4x
For what missing value(s), if any, does the equation have exactly one solution?
There is no value for which the missing place should be filled in order to have exactly one solution.
A Linear equation may be defined as the one which can be represented in the form ax + b = 0 where a, b are coefficients and x is the independent variable. Since the equation only has one variable that is x then the linear equation will be rightly called as linear equation in one variable. We are given the equation -2(2x - _) + 1 = 17 - 4x. We solve the equation further which results as
-4x - _ + 1 = 17 - 4x
As we can see that there is -4 in both the right-hand side as well as the left-hand side both of them gets cancelled out.
- _ +1 = 17
As we can see that there is no variable left in order to find the value so any value of missing space will not be able to give any solution.

What is a graph?A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.
In Mathematics, the graph of any proportional relationship is characterized by a straight line with the points passing through the origin (0, 0) because as the values on the x-axis (x-coordinate) increases or decreases, the values on the y-axis (y-coordinate) increases or decreases simultaneously.
In this context, we can reasonably infer and logically deduce that the relationship between x-values and y-values in this graph is not proportional.

two carts, a and b, are connected by a rope 39 ft long that passes over a pulley p. the point q is on the floor 12 ft directly beneath p and between the carts. cart a is being pulled away from q at a speed of 2 ft/s. how fast (in ft/s) is cart b moving toward q at the instant when cart a is 5 ft from q? (round your answer to two decimal places.)
The velocity of the cart b is found as 20/23 ft/s over the pulley.
What is defined as the rate of change?The momentum of a variable is represented by the rate of change, which is used to mathematically define the percentage change in value over such a defined period of time.For the given data in the question.
q's velocity is 2 feet per second.
Rope length is 39 feet.
Assume x is the distance between A and Q. (refer the image).
Assume y is the distance between Q and B. (refer the image).
As a result of the image,
x² + 12² = L²
Now, with respect to time t, differentiate the above equation.
2x(dx/dt) + 0 = 2L.(dL/dt)
For x = 5 ft and L = 13 ft
dL/dt = (5×2)/13 = 10/13
In the case of B,
y² + 12² = (39 - L)² ; from diagram.
Differentiating now,
2y(dy/dt) + 0 = -2(39 - L).(dL/dt)
At x = 5 ft and y = 23 ft.
dy/dy = -20/23
(A negative sign indicates the opposite direction)
Thus, the velocity of cart b is found as 20/23 ft/s.

Suppose PQ has one endpoint at P (4, 6) and a midpoint coordinate of (-5, 9).
The coordinate for Point Q is
Answer:
(-14,12)
Step-by-step explanation:
Way 1: (little more complicated)
we know two things,
The two halves of the line have the same slope, and that the length from the endpoint to the midpoint is equal to the length from the midpoint to the other end point.
The slope is equal to: (6-9)/(4-(-5)) = -3/9 = -1/3
The length is equal to (using the Pythagorean theorem):
height = delta y = 9 - 6 = 3
length = delta x = 4 - (-5) = 9
3^2+9^2=hypotenuse^2
9+81 = h^2
h = sqrt(90)
So, the let's say point Q has the coordinate (a, b).
The formula of the slope would give us (b-9)/(a-(-5)) = -1/3
The formula of the hypotenuse would give us (b-9)^2+(a-(-5))^2 = 90
solving the system of equations, we would get that a = -14 and b = 12, so the point is (-14,12)
Make sure to be careful, however, because you will get two points with this system of equations. Only one works
Way 2:
since from point P to the midpoint we went to the left by 9 and up by 3, from the midpoint to point Q, we would go left by 9, and up by 3.
from the midpoint (-5,9), go left by 9, so x decreases by 9 to get (-14, 9).
go up by 3, so y increases by 3 to get (-14,12). This agrees with our other answer

Slope, m = 5/4
Point, (x1, y1) = (1, 3)
A linear equation is represented as
y = m(x - x1) + y1
So, we have

This gives
y = 5/4x + 7/4
Hence. the linear equation is y = 5/4x + 7/4
The equivalent equationsHere, we have
(x, y) = (3, 0) and (0, 2)
A linear equation is represented as
y = m(x - x1) + y1
Where
m = (y2 - y1)/(x2 - x1)
So, we have
m = (2 - 0)/(0 - 3)
m = -2/3
So, we have
y = -2/3(x - 3)
