The midpoint of the line segment FG is the point (4, 12).
What is midpoint?In geometry, the midpoint of a line segment is the point that is exactly halfway between the endpoints of the segment. It is the point that divides the segment into two congruent segments.
The formula for finding the midpoint of a line segment with end points (x₁, y₁) and (x₂, y₂) is:
Midpoint = [(x₁ + x₂)÷2, (y₁ + y₂)÷2]
So, the midpoint of the line segment with endpoints F(-10, 12) and G(18, 12) can be found as:
Midpoint = [(-10 + 18)÷2, (12 + 12)÷2]
= [8÷2, 24÷2]
= [4, 12]
Therefore, the midpoint of the line segment FG is the point (4, 12).

Determine the equation of the circle with center (6,-2)containing the point (14,6).
Answer:
(x -6)² +(y +2)² = 128
Step-by-step explanation:
You want the equation of the circle centered at (6, -2) through point (14, 6).
Circle equationThe equation of a circle with center (h, k) and radius r is ...
(x -h)² +(y -k)² = r²
For center (h, k) = (6, -2), we can find the value of r² knowing that it will be the value that lets the point (14, 6) satisfy the equation.
(14 -6)² +(6 -(-2))² = r² = 8² +8² = 128
The circle equation is ...
(x -6)² +(y +2)² = 128
Enter the endpoints as ordered pairs (x, y).
Provide your answer below:
The endpoints of the latus rectum are and
(y + 3)² = (x - 2)
The endpoints of the latus rectum of the parabola are (3, -2) and (3, -4)
Given data ,
Let the equation of the parabola be (y + 3)² = (x - 2)
Now , y² + 6y + 9 = x - 2
y² + 6y = x - 11
Now we can see that the vertex of the parabola is (2, -3), and the axis of symmetry is parallel to the y-axis. This means that the focus and directrix will also be parallel to the y-axis.
x = h - p
where (h, k) is the vertex and "p" is the distance between the vertex and the focus. In this case, (h, k) = (2, -3) and p = 1, so
x = 2 - 1
x = 1
Therefore, the equation of the directrix is x = 1
And , the axis of symmetry of the parabola is parallel to the y-axis, the latus rectum will be parallel to the directrix, and its endpoints will be equidistant from the focus and the directrix
The distance between the focus and the directrix is 1 unit, so the distance between the endpoints of the latus rectum will also be 1 unit
Therefore, the endpoints of the latus rectum will be at the points where the perpendiculars drawn from the focus to the directrix intersect the parabola
To find the points of intersection between this line and the parabola, we can substitute x = 3 into the equation of the parabola and solve for y
(y + 3)² = (x - 2)
(y + 3)² = (3 - 2)
(y + 3)² = 1
y + 3 = ±1
y = -2 or y = -4
Hence , the points of intersection between the perpendicular and the parabola are (3, -2) and (3, -4)

Determine the equation of the circle. Center: (1,5) Radius: 2
The equation of the circle is x² + y² - 2x - 10y + 22 = 0
Define circleAny locations on a plane that are a certain distance from a fixed point (referred to as the radius) are considered to be parts of a circle, which is a two-dimensional geometric shape (is called the center). Each point on the circle may be found at the same distance from the circle's centre.
The following is the equation for a circle with centre (h,k) and radius r:
r²=(x - h)² + (y - k)²
In this case, the center of the circle is (1,5) and the radius is 2. So, we may change these values in the equation:
(x - 1)² + (y - 5)² = 2²
Simplifying and expanding the equation, we get:
(x - 1)×(x - 1) + (y - 5)(y - 5) = 4
x² - 2x + 1 + y² - 10y + 25 = 4
x² + y² - 2x - 10y + 22 = 0
Therefore, the equation of the circle is:
x² + y² - 2x - 10y + 22 = 0

P(964.6 < M < 1000.1) = ???
The probabilities are given as follows:
P(964.6 < X < 1000.1) = 0.071 = 7.1%.P(964.6 < M < 1000.1) = 0.338 = 33.8%How to obtain probabilities using the normal distribution?The z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is obtained by the equation presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution of the data-set, depending if the obtained z-score is positive(above the mean) or negative(below the mean).The z-score table is used to obtain the p-value of the z-score, and it represents the percentile of the measure X in the distribution.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation given by the equation presented as follows: [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].The mean and the standard deviation for this problem is given as follows:
[tex]\mu = 957, \sigma = 193[/tex]
The probability is the p-value of Z when X = 1000.1 subtracted by the p-value of Z when X = 964.6, hence:
Z = (1000.1 - 957)/193
Z = 0.22.
Z = 0.22 has a p-value of 0.5871.
Z = (964.6 - 957)/193
Z = 0.04.
Z = 0.04 has a p-value of 0.5160.
Hence:
0.5871 - 0.5160 = 0.0711.
For the sample of 58, the standard error is obtained as follows:
s = 193/sqrt(58) = 25.34.
Hence:
Z = (1000.1 - 957)/25.34
Z = 1.7.
Z = 1.7 has a p-value of 0.9554.
Z = (964.6 - 957)/25.34
Z = 0.3.
Z = 0.3 has a p-value of 0.6179.

How did we get the values?Question 5:
Apply the Pythagorean theorem to find the distance r from the fire station to the destination:
r = √(62 + 11²) = 12.53 (rounded to the nearest hundredth)
The angle θ between the positive x-axis and the line connecting the fire station to the destination is found using tangent:
tan(θ) = ¹¹/₆
θ = arctan(¹¹/₆) = 61.39° (rounded to the nearest hundredth)
Therefore, the answer is (12.53, 61.39°), which is option D.
Answer: D. (12.53, 61.39°)

y = -7 sin(3π/4) = -7√(2)/2) = -3.5√(2)
Therefore, the rectangular coordinates of the point are (3.5sqrt(2), -3.5sqrt(2)), which can also be written as (-4.95, -4.95) (rounded to the nearest hundredth).

A container built for transatlantic shipping is constructed in the shape of a right rectangular prism. Its dimensions are 4.5 ft by 11.5 ft by 10.5 ft. The container is entirely full. If, on average, its contents weigh 0.4 pounds per cubic foot, and, on average, the contents are worth $4.60 per pound, find the value of the container’s contents. Round your answer to the nearest cent.
The value of the container's contents is approximately $983.25
What is the value of the container's contents?To find value of the contents, we must calculate its volume first.
Volume = length x width x height
Volume = 4.5 ft x 11.5 ft x 10.5 ft
Volume = 534.375 cubic feet
The container is full and its contents have a volume of 534.375 cubic feet. If its contents weigh 0.4 pounds per cubic, then, total weight of the contents is:
= Volume x Weight per cubic foot
= 534.375 cubic feet x 0.4 pounds per cubic foot
= 213.75 pounds
If the contents are worth $4.60 per pound on average, then the total value of the contents is:
= Weight x Value per pound
= 213.75 pounds x $4.60 per pound
= $983.25.

What is the probability that the marble is not green?
the probability that the marble is not green is 0.9 or 90%. This means that if we were to randomly select a marble from the box, there is a 90% chance that it will not be green.
How to solve probability?
To calculate the probability that a marble is not green, we need to first determine the total number of marbles in the box, which is given by:
Total number of marbles = 8 + 6 + 2 + 4 = 20
Next, we need to determine the number of marbles that are not green. Since there are 2 green marbles, the number of marbles that are not green is given by:
Number of marbles that are not green = 20 - 2 = 18
Finally, we can calculate the probability of selecting a marble that is not green by dividing the number of marbles that are not green by the total number of marbles in the box, as follows:
Probability of selecting a marble that is not green = Number of marbles that are not green / Total number of marbles
= 18 / 20
= 0.9 or 90%
Therefore, the probability that the marble is not green is 0.9 or 90%. This means that if we were to randomly select a marble from the box, there is a 90% chance that it will not be green.

Let b represent the number of bracelets and r represent the number of rings.
The equation that represent the number of bracelets b and the number of rings r is 6b + 8r > 600 and 2b + 4r < 275, hence, option A is correct.
Let b represent the number of bracelets and r represent the number of rings that Marisol makes. Marisol plans to sell each bracelet for $6 and each ring for $8. So the amount she earns from selling bracelets is 6b and the amount she earns from selling rings is 8r.
The craft fair committee charges a $25 fee to sell at the fair. So Marisol's total earnings after paying the fee is 6b + 8r - 25. It costs Marisol $2 to make a bracelet and $4 to make a ring. So the total cost of making b bracelets and r rings is 2b + 4r. To make a profit, Marisol's earnings must be greater than her costs,
6b + 8r - 25 > 2b + 4r
Simplifying this inequality, we get,
4b + 4r > 25
We also know that Marisol wants to sell at least $600 in jewelry. This can be expressed as,
6b + 8r > 600
Finally, Marisol wants to spend less than $300 for supplies and the fee. This can be expressed as,
2b + 4r + 25 < 300
Simplifying this inequality, we get,
2b + 4r < 275
Therefore, the system of inequalities that represents the situation is,
6b + 8r > 600
4b + 4r > 25
2b + 4r < 275
where b represents the number of bracelets and r represents the number of rings that Marisol makes.
