The slope of the line containing the pair of points (5,-10) and (-3,-10) = m = 0.
Slope of a line
In Mathematics, a slope of a line is the change in y coordinate with respect to the change in x coordinate. The net change in y-coordinate is represented by Δy and the net change in x-coordinate is represented by Δx.
Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
Given that the line containing the pair of points (5,-10) and (-3,-10).
Slope of a line = (y2 - y1)/ (x2 - x1)
Here
y1 = -10
x1 = 5
y2 = -10
x2 = -3
Therefore slope of a line = m = [-10 - (-10)]/ (-3 - 5)
= 0/ (-8)
= 0

x to the power of 7 divided by x to the power of 4
Using the product rule of power, the expression, x^7 / x^4 = x³.
How to Divide Numbers with Powers but the same Base?If the bases are the same for two numbers having powers, the product rule of power or exponent states that we are to subtract their powers.
For example, if we are given m³ divide by m², that is m³ / m², therefore we would have:
m³ / m² = m^(3 - 2)
m³ / m² = m [the power will now be 1]
In the same vein, we can simplify "x to the power of 7 divided by x to the power of 4" as shown below:
x^7 / x^4 = x^(7 - 4) [based on the product rule of powers or exponents]

as an avid fisherman, nick was curious if the advertised strength of fishing line is accurate. to investigate, he used "6 pound" fishing line to hang a bucket, which he then filled with weights until the line broke. then nick measured the total weight of the bucket and its contents to determine the breaking strength of that piece of fishing line. after trying this with many different sections of the fishing line, he estimated that the distribution of breaking strength for this type of line is approximately normal with a mean of 6.44 pounds and a standard deviation of 0.75 pound.
Using the normal distribution, it is found that this type of fishing line have a breaking strength less than the advertised 6 pounds 27.76% of the time.
Normal Probability DistributionThe 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 given by the following rule:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure X is above or below the mean, depending if the z-score is positive or negative.From the z-score table, the p-value associated with the z-score is found, and it represents the percentile of the measure X.The mean and the standard deviation for the breaking strengths are given as follows:
[tex]\mu = 6.44, \sigma = 0.75[/tex]
The proportion of times with breaking strength less than 6 inches is given by the p-value of Z when X = 6, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (6 - 6.44)/0.75
Z = -0.59
Z = -0.59 has a p-value of 0.2776.

in a study by giacobbi et al. (2014), it was determined that about 60% of the participants found imagery very helpful in enhancing their physical activity, but 40% said they would no longer use imagery in their exercise. the implication from these results is that
Before offering imaging programs, practitioners need to be aware of the reasons why exercise participants are doing it.
Define imagery in sports.When we use imagery, we simulate an actual situation in our minds rather than actually going through it. It differs significantly from daydreaming or simply thinking about anything because it is a cognitive activity that is consciously used by an athlete or exerciser to accomplish a certain task.
In this study, an analysis of secondary data from a recently published randomized controlled trial. In a community-based, group-mediated physical activity intervention for sedentary people 50 and older, the Active Adult Mentoring Program (AAMP) tested the effectiveness of peer volunteers as delivery agents. The AAMP was built on the social-cognitive and self-determination theories, and mentors were trained to lead discussions in groups that would help reinforce key ideas from both theories.
The adaptability of images makes it useful at different times and in varied settings. Athletes employ imagery most frequently right before a competition or during practice, but they do so during the entire season, including the off-season. Similar to how it's reported by athletes, visualization is frequently used before an activity session. For example, it would be more effective for a swimmer to mentally practice her race start by adopting the proper position on the starting block at the swimming pool, as opposed to sitting on a chair at home. Both types of people will typically imagine within the sport and exercise environment where the benefits of this technique are maximized.

4) Substitution Property
5) Subtraction Property of Equality
Given: l || m
Prove:
∠4 = ∠6
2) m∠3 + m∠4 = 180
This is because angles 3 and 4 are supplementary as they lie on a straight line. If the total of two angles is 180 degrees, they are considered to be supplementary angles since they form a linear angle when combined.
3) m∠3 + m∠6 = 180
By the Same-side Interior Angles Postulate when a transversal connects two parallel lines, the interior angles on the same side are supplementary. Hence angles 3 and 6 are supplementary.
4) m∠3 + m∠4 = m∠3 + m∠6
Using Substitution Property we can replace angle 4 with angle 6, the value or sum will still remain the same i.e. 180.
5) m∠4 = m∠6
By the Subtraction Property of Equality, we can subtract the angle 3 from both sides of the equation in part(4) and the resultant equation will be m∠4 = m∠6.

Consider a circle whose equation is x2 + y2 – 2x – 8 = 0. Which statements are true? Select three options.
The radius of the circle is 3 units.
The center of the circle lies on the x-axis.
The center of the circle lies on the y-axis.
The standard form of the equation is (x – 1)² + y² = 3.
The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.
The correct statement are;
1. The radius of the circle is 3 units.
2. The center of the circle lies on the x-axis.
3. The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.
What is Circle?
The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Given that;
The equation of circle will be;
⇒ x² + y² - 2x - 8 = 0
The standard form of the equation of circle is;
⇒ x² + y² + 2gx + 2fy + c = 0
Where,
The center of circle = (-g , -f)
The radius of circle = √g² + f² - c
Since, The equation of circle will be;
⇒ x² + y² - 2x - 8 = 0
Compare with the standard form of circle, we get;
⇒ 2gx = - 2x
⇒ g = - 1
And, 2fy = 0
⇒ f = 0
Hence, The center = ( -g , -f) = (- (-1) , 0)
= (1, 0)
Clearly, This shows the center of circle is lies on x - axis.
Radius of circle = √g² + f² - c
Substitute all the values we get;
Radius of circle = √g² + f² - c = √(-1)² + 0 - (-8)
= √9
= 3
Thus, The radius of the circle is 3 units.
Now, For the equation of circle x² + y² = 9,
Radius = √9 = 3 units.
So, The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.
Therefore, The correct statement are;
1. The radius of the circle is 3 units.
2. The center of the circle lies on the x-axis.
3. The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.

Incenter and circumcenter of the triangle:
Incenter:
The intersection point of all three interior angle bisectors of the triangle is known as the Incenter of the triangle. It is the center of the large circle that can fit in the triangle.
Circumcenter:
The point of intersection of perpendicular bisectors of three sides of a triangle. It will be equidistant from the three vertices of a triangle.
Here we have,
The sides of a triangle are 5, 12, 13
Let the given triangle is triangle ABC
then AB = 5, BC = 13 and AC = 12
[ For more understanding observe the given picture]
As we know (5, 12, 13) is a triplet
then the Given triangle is a right-angled triangle
Let us assume that the triangle is in a graph as the right angle at the origin then the vertices of the triangle are
A = (0, 0); B = (0, 5) and C = (12, 0)
Now find the incenter and circumcenters of the triangle using the above information
The incenter of the triangle
=> (x, y) = [tex][ \frac{0(BC) + 0(AC)+ 12(AB) }{AB+AC+AB}, \frac{0(BC) + 5(AC) + 0(AB) }{AB+AC+AB} ][/tex]
=> (x, y) = [tex][ \frac{0(13) + 0(12)+ 12(5) }{5+12+13}, \frac{0(13) + 5(12) + 0(5) }{5+12+13} ][/tex]
=> (x, y) = [tex][ \frac{60 }{30}, \frac{60 }{30} ][/tex] = (2, 2)
The circumcenter of the triangle
As we know in a right-angled triangle,
Circumcenter = Midpoint of Hypotenuse
= Midpoint of B(0, 5) and C (12, 0)
= [ (12 + 0) / 2 , (5 + 0) /2 ]
= (6, 5/2)
From the above calculations,
The incenter of the triangle is (2, 2)
The circumcenter of triangle is (6, 5/2)
Distance between two centers = √ [ ( 6 - 2)² + ( 5/2 - 2)² ]
= √[ (4)² + (1/2)² ]

Vince took out a $500 loan to buy a new
couch. He paid back the loan in 2 years and
paid a total of $570. What was the simple
interest rate for his loan?
Answer:
Step-by-step explanation:
The requried, simple interest rate for Vince's loan was 7%.
What is simple interest?Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan.
Amount = Principal [1 + rate×time]
We can use the simple interest formula to solve this problem, where:
Simple interest = Principal x Rate x Time
In this case, the principal is $500, and the time is 2 years. We can rearrange the formula to solve for the rate:
Rate = Simple interest / (Principal x Time)
The total amount paid back, including the principal and the interest, is $570. So, the simple interest can be calculated as:
Simple interest = Total amount paid - Principal
Simple interest = $570 - $500
Simple interest = $70
Substituting these values into the formula, we get:
Rate = $70 / ($500 x 2)
Rate = $70 / $1000
Rate = 0.07 or 7%
Therefore, the simple interest rate for Vince's loan was 7%.
