Write an equation of the line, in point-slope form, that passes through the two given points.
Answer:
(y-8) = -1/2(x+17)
Step-by-step explanation:
slope = (-2 - 8) / (3 - (-17)) = -10 / 20 = -1/2
area = 3024 cm^2
h = 36
a = 78
b = ?
Area = 3024 cm^2, h = 36 and a = 78 the value of a and b needs to be determined, given the area 3024 cm^2 and height 36.
Using the formula for the area of a parallelogram, area = base * height, we can rearrange the formula to solve for the base: base = area / height. Plugging in the given values, we get base = 3024 / 36 = 84 cm.
Since a and b represent the lengths of the two sides of the parallelogram, we can use the formula for the perimeter of a parallelogram, perimeter = 2(a + b), to solve for a and b. Rearranging the formula, we get (perimeter/2) - a = b.
To find the perimeter, we need to use the Pythagorean Theorem since we know the height and base of the parallelogram.
Using the formula c = sqrt(a^2 + b^2) to find the length of the slant height, we get c = sqrt(36^2 + 84^2) = 90 cm. The perimeter is 2(c + base) = 2(90 + 84) = 348 cm.
Substituting perimeter = 348, a = 78, and solving for b, we get b = (perimeter/2) - a = 174 - 78 = 96. Therefore, a = 78 and b = 96.

in utah, if not directly involved in diving activity, motorized vessels and personal watercraft (pwcs) must remain what distance from diver down flags?
In Utah, if not directly involved in diving activity, motorized vessels and personal watercraft (PWCs) must remain 150 feet from the diver down flags.
The diver down flag is a banner that is used by vessels to indicate that divers are in the water. It is typically a red flag with a white diagonal stripe that is used to indicate the presence of divers in the water. The flag must be at least 12 x 12 inches in size and must be clearly visible from all directions. When the flag is raised, boaters are expected to keep a safe distance from the divers and to take extra precautions to ensure that they do not pose a hazard to the divers.The diver down flag should be used whenever there are divers in the water. This includes scuba divers, free divers, and anyone else who is swimming or diving underwater. The flag should be raised before the divers enter the water and should be lowered when they exit the water. In addition to the flag, divers are required to use other means of indicating their presence in the water, such as lights and audible signals, to ensure that boaters can see and hear them. Motorized vessels and personal watercraft (PWCs) must remain at least 150 feet from the diver-down flag. This means that they must keep a safe distance from the divers and take extra precautions to ensure that they do not pose a hazard to the divers. If a motorized vessel or PWC is directly involved in the diving activity, such as transporting divers to and from the dive site, they may operate closer to the flag, but they must still maintain a safe distance from the divers at all times.

write y=x^2+24x+124 in vertex form. step by step
Step-by-step explanation:
the general vertex form is
y = a(x - h)² + k
with (h, k) being the vertex of the curve.
after doing all the multiplications we get
y = a(x² - 2hx + h²) + k = ax² - 2ahx + ah² + k
now we have
y = x² + 24x + 124
and we can compare
ax² = x²
a = 1
-2ahx = -2hx = 24x
-2h = 24
h = 24/-2 = -12
ah² + k = 124
(-12)² + k = 124
144 + k = 124
k = -20
so, the vertex form is
y = (x + 12)² - 20

whats the answer to this. In circle K with m \angle JKL= 144m∠JKL=144 and JK=6JK=6 units, find the length of arc JL. Round to the nearest hundredth.
The length of arc JL is 24.46 units see attachment for diagram.
What is an arc?An arc is a part of the circumference of a circle that meets two radii of a circle to form a sector.
Analysis:
From bigger triangle, if we bisect 144, the line meets JL at 90°.
To find AL,
sin 72 = AL/6
AL = 6 sin 72 = 5.71
To find the angle at O
∠O = 2∠K ( twice angle at circumference is equal to angle at center)
∠O = 2 (144) = 288°
For smaller right-angled triangle,
sin 144 = AL/OL
sin 144 = 5.71/OL
OL = radius of circle = 5.71/0.587 = 9.73 unit
length of arc JL = ∅/360 x 2πr
= 144/360 x 2 x 3.142 x 9.73 = 24.46 units
In conclusion, the length of arc JL is 24.46 units

Answer:
The set of numbers that could not represent the three sides of a right triangle are;
{9, 24, 26}
Step-by-step explanation:
According to Pythagoras's theorem, when the lengths of the three sides of a right triangle includes two legs, 'x', and 'y', and the hypotenuse side 'r', we have;
r² = x² + y²
Where;
r > x, r > y
Therefore, analyzing the options using the relationship between the numbers forming the three sides of a right triangle, we have;
Set 1;
95² = 76² + 57², therefore, set 1 represents the three sides of a right triangle
Set 2;
82² = 80² + 18², therefore, set 2 represents the three sides of a right triangle
Set 3;
26² = 24² + 9², therefore, set 3 could not represent the three sides of a right triangle
Set 4;
39² = 36² + 15², therefore, set 4 represents the three sides of a right triangle
What additional information is obtained from measurements on an ordinal scale compared to measurements on a nominal scale
Measurements on an ordinal scale offer additional information by providing an ordered arrangement of categories or variables, enabling comparisons and understanding of relative positions or preferences.
Measurements on an ordinal scale provide additional information compared to measurements on a nominal scale by allowing for the establishment of a ranking or order among the measured categories or variables. While a nominal scale categorizes data into distinct groups without any inherent order, an ordinal scale assigns a specific order or hierarchy to the categories or variables being measured.
With measurements on an ordinal scale, it becomes possible to determine the relative position, preference, or level of a particular category or variable in relation to others. This ordering provides more nuanced information about the data, allowing for comparisons such as "greater than" or "less than" relationships. However, the precise magnitude or interval between categories is not defined in an ordinal scale, unlike in other scales like interval or ratio scales.

Step-by-step explanation:
the caffeine content of 8-ounce cans of a certain cola drink is approximately normally distributed with mean 33 milligrams (mg). a randomly selected 8-ounce can containing 35 mg of caffeine is 1.2 standard deviations above the mean. approximately what percent of 8-ounce cans of the cola have a caffeine content greater than 35 mg?
The percentage of 8-ounce cans of cola having a caffeine content greater than 35mg is approximately 12%.
We find the standard deviation.
A randomly selected 8-ounce can contain 35mg of caffeine is 1.2 standard deviations above the mean.
Mean = 33mg
35 = Mean - 1.2(standard deviation)
35 = 33 + 1.2(standard deviation)
35 - 33 = 1.2(standard deviation)
2 = 1.2(standard deviation )
Standard deviation = 2/1.2
= 1.6666666667
= 1.67
Therefore, the standard deviation is 1.67.
Using the z-score formula
Z score = x - μ/σ
x = 35mg
μ = mean = 33mg
σ= standard deviation = 1.67
Z score = 35 - 33/1.67
= 1.1976
Probability value from Z-Table:
P(x<35) = 0.88446
P(x>35) = 1 - P(x<35)
= 1 - 0.8844
= 0.11554
Converting to percentage = 0.11554 × 100
= 11.554%
≈ 12%
Therefore, the percentage of 8-ounce cans of cola having a caffeine content greater than 35mg is approximately 12%.

When the area corresponding to the critical value is in the lower tail of the sampling distribution, the p-value is the area under the curve
a. less than or equal to the critical value.
b. less than or equal to the test statistic.
c. greater than or equal to the critical value.
d. greater than or equal to the test statistic.
When the area corresponding to the critical value is in the lower tail of the sampling distribution, the p-value is the area under the curve less than or equal to the critical value. Therefore, the correct answer is a. less than or equal to the critical value.
The critical value is the point on the sampling distribution that separates the rejection region from the non-rejection region. If the test statistic falls in the rejection region, we reject the null hypothesis. The p-value is the probability of obtaining a test statistic as extreme or more extreme than the one observed, given that the null hypothesis is true. If the p-value is less than or equal to the critical value, we reject the null hypothesis.
In the case of a lower-tailed test, the critical value is in the lower tail of the sampling distribution, and the p-value is the area under the curve to the left of the test statistic. If the p-value is less than or equal to the critical value, it means that the test statistic falls in the rejection region and we reject the null hypothesis.

The two places she can put lens and give object and image distances are 15cm and 75cm.
The Lens equation gives us:
1/f = 1/u + 1/v
From the problem we know that,
v=90-u
By solving
u² - 90u + 1125 = 0.
An optical system's focal length, which is the inverse of the system's optical power, indicates how strongly the system converges or diverges light. A system with a positive focal length is said to converge light, and one with a negative focal length is said to diverge light.
A negative focal length, on the other hand, indicates how far in front of the lens a point source must be located to form a collimated beam, for the special case of a thin lens in air, where a positive focal length is the distance over which initially collimated (parallel) rays are brought to a focus.

How can you solve a linear system (Ax=b) using inverse matrices?
To solve for x, we just need to compute the inverse of A (if it exists) and multiply it by b. If A is invertible, then this method will give us the unique solution to the linear system Ax=b.
To solve a linear system of the form Ax=b using inverse matrices, we can first find the inverse of matrix A (if it exists) and then multiply both sides of the equation by \(A^-1\), giving us:
\(A^-1Ax = A^-1b\)
Since\(A^-1A\) is the identity matrix I, we can simplify the left-hand side to just x:
\(x = A^-1b\)
However, it's worth noting that computing the inverse of a matrix can be computationally expensive, particularly for large matrices.
So, while using inverse matrices can be a useful technique for solving small systems, it may not be the most efficient approach for larger systems. In those cases, other techniques such as Gaussian elimination or LU decomposition may be more appropriate.

Step-by-step explanation:
Maya has a home-based business making and selling scented soaps. She initially spent $60 to purchase soap-making equipment, and the materials for each pound of soap cost $2. Maya sells the soap for $14 per pound. Eventually, she will sell enough soap to cover the cost of the equipment. How much soap will that be?
Maya will need to sell 5 pounds of soap to cover the cost of the equipment.
First, let's identify the relevant terms:
- Initial equipment cost: $60
- Cost of materials per pound of soap: $2
- Selling price per pound of soap: $14
To find out how much soap Maya needs to sell to cover the cost of the equipment, we can set up an equation:
- Revenue = Cost of equipment + Cost of materials
- Revenue = $14 × pounds of soap sold
Next, we can solve for the number of pounds of soap Maya needs to sell:
- $14 × pounds of soap sold = $60 (equipment cost) + $2 × pounds of soap sold
- $14 × pounds of soap sold - $2 × pounds of soap sold = $60
- $12 × pounds of soap sold = $60
Finally, we can find the number of pounds of soap:
- pounds of soap sold = $60 / $12
- pounds of soap sold = 5
