x=5 is the required equation of straight line
What is slope of line ?The steepness of a line is determined by its slope. The slope is m in the equation for a line that is typically used, y = mx + b. The term "rise over run" is also frequently used to describe it and describes how much the y-value changes as the x-value does.
According to the given value;
slope of line is Y₂-Y₁/X₂-X₁
hence slope for given line will be
3-(-2)/5-5 =5/0 = ∞
slope is infinity means straight line is vertical in nature and vertical lines are of the form x=a where a is some constant
now we can observe that 5 is constant in both the given points so x=5 is the required line which passes through (-2,-6),(-2,5)
Hence,x=5 is the required equation of straight line .

What is the distance between the two bodies halved?.
When distance is halved, force increases by 4 times.
What is gravitational force?
Each body in the universe attracts other bodies towards itself with a force known as Gravitational Force
Gravitational force is a central force which depends only on the position of test mass from the source mass and always acts along the line joining the centres of two masses.According to Newton’s law of gravitation, “Every particle in universe attracts every other particle with a force whose magnitude is,
Directly proportional to product of their masses, i.e., F ∝ (M1M2)Inversely proportional to the square of the distance between their centre, i.e., (F ∝ 1/r²)On combining these equations, we get
F = G × [M1M2]/r²
F ∝ M1M2/r²
Now , r' = r/2 ( given)
so, F' ∝ (m1m2) / (r/2)²
F' ∝(4 m1m2) / r²
Thus F' = 4×F
So, we can conclude that, when distance is halved, force increases by 4 times.

Which of the following measures is not needed for constructing a box-plot?
A> First quartile
B. 50th percentile
C. 75th percentile
D. 95th percentile
The answer is D. 95th percentile is not needed for constructing a box-plot.
A box plot, also known as a box-and-whisker plot, provides a visual representation of the distribution of a dataset. It consists of several key measures, including the following:
A. First quartile (Q1): This is the 25th percentile, which marks the lower boundary of the box.
B. 50th percentile: This is the median, which is the middle value of the dataset when it is ordered from smallest to largest. It is represented by a line within the box.
C. 75th percentile (Q3): This is the upper quartile, marking the upper boundary of the box.
D. 95th percentile: This measure is not typically used in constructing a box plot. It provides information about the value below which 95% of the data falls, but it is not necessary for constructing the basic elements of a box plot.
Therefore, the correct answer is D. 95th percentile.

The number of CDs per hour that Snappy Hardware can manufacture at its plant is given by P=064 where x is the number of workers at the plant and y is the monthly budget in dollars. Assuming that P is constant.compute dy/d when w100 and y 120,000, Coninuing with the previous problem,give an interpretation in 3 parts of the value you computed in terms of CDs produced by Snoppy Hardware.
The value of dy/d in this case represents the rate of change in the monthly budget required to maintain a constant production level of CDs.
When w100 and y 120,000, dy/d can be computed by taking the partial derivative of the given equation with respect to y: dy/d = -0.64/x. Plugging in the given values, we get dy/d = -0.0064.
1. If the monthly budget is increased by $1, Snappy Hardware can manufacture 0.0064 fewer CDs per hour while maintaining the same number of workers.
2. If the number of workers is increased by 1, Snappy Hardware can manufacture an additional 0.0064 CDs per hour while maintaining the same monthly budget.

To solve 3 ≥ 5 - 2x, a student typically uses division by -2 and reverses the direction of the inequality. Use the Addition Property of Equality.
which of the following is a factor of 12x2 − 4x − 1?
To find the factors of the expression 12x^2 - 4x - 1, we can use the factor theorem. The factor theorem states that if a polynomial expression evaluates to zero when a certain value is substituted for the variable, then that value is a factor of the polynomial.
To determine if a certain value is a factor of the expression, we can use synthetic division. Synthetic division involves dividing the polynomial expression by the possible factor to check if the remainder is zero. If the remainder is zero, then the value is a factor.
Let's start by checking if x = 1 is a factor of the expression:
1 | 12 - 4 - 1
| 12 8
|____________
12 8 7
Since the remainder is not zero, x = 1 is not a factor of the expression.
Next, let's check if x = -1 is a factor of the expression:
-1 | 12 - 4 - 1
| -12 16
|____________
12 -16 15
Again, the remainder is not zero, so x = -1 is not a factor of the expression.
Now, let's check if x = 2 is a factor of the expression:
2 | 12 - 4 - 1
| 24 40
|____________
12 20 39
Once again, the remainder is not zero, so x = 2 is not a factor of the expression.
Finally, let's check if x = -2 is a factor of the expression:
-2 | 12 - 4 - 1
| -24 56
|____________
12 -28 55
As we can see, the remainder is not zero, so x = -2 is not a factor of the expression.
After checking all the possible factors, we can conclude that none of the values tested (1, -1, 2, -2) are factors of the expression 12x^2 - 4x - 1.

The length of an arc of a circle is 26/9 pi centimeters and the measure of the corresponding central angle is 65 . What is the length of the circle's radius?
Therefore, the length of the circle's radius is approximately 3.6923 centimeters.
To find the length of the circle's radius, we can use the formula relating the length of an arc to the radius and the measure of the corresponding central angle.
The formula is given by:
Length of arc = radius * (angle in radians)
In this case, the length of the arc is given as (26/9)π centimeters and the measure of the central angle is 65 degrees.
First, we need to convert the angle from degrees to radians. Since 180 degrees is equal to π radians, we have:
65 degrees = (65/180)π radians
Now we can substitute the given values into the formula:
(26/9)π = radius * (65/180)π
We can simplify the equation by canceling out the π terms:
26/9 = radius * (65/180)
To solve for the radius, we can isolate it by dividing both sides of the equation by (65/180):
radius = (26/9) / (65/180)
Simplifying the right side of the equation:
radius = (26/9) * (180/65)
Calculating the value:
radius ≈ 3.6923 cm

From her eye, which stands 1.68 meters above the ground, Hannah measures the Angel elevation to the top of the prominent skyscraper to be 31 degrees. If she is standing at a horizontal distance if 194 meters from the base of the sky scrapper, what is the height of the skyscraper. Round your answer to the nearest hundredth of a meter if necessary
The Total height of skyscraper from ground is; 118.25 m
How to solve Angle of elevation problems?The formula to use tangent as trigonometric ratio is;
tan θ = Perpendicular/Base
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The base is the adjacent smaller side of the angle θ.
Since the horizontal distance between Hannah's eyes and the sky scrapper is 194 meters while the angle between the eye and the top of the sky scrapper is 31°. Therefore, the vertical height of the sky scrapper from the height of Hannah's eye level, using the tangent function can be written as;
tan 31 = height of skyscraper from eye level/194
height of skyscraper from eye level = 116.57 m
Total height of skyscraper from ground = 116.57 m + 1.68 m

suppose that the slope parameter in a simple linear regression model is β1 = 3.52. what does this suggest about the nature of the relationship between x and y?
A slope parameter of β1 = 3.52 in a simple linear regression model suggests that there is a positive and direct relationship between the independent variable (x) and the dependent variable (y).
Specifically, for every one unit increase in the independent variable (x), the dependent variable (y) is expected to increase by an average of 3.52 units. This indicates a positive linear association between x and y, implying that as x increases, y tends to increase as well.
The magnitude of the slope parameter (3.52) also indicates the steepness of the relationship. A larger slope suggests a stronger relationship, indicating that the change in y for a given change in x is relatively large.
