Answer: 3
Step-by-step explanation:
This equation is given to us in point-slope form.
The slope is m in (y - \(y_1\)) = m(x - \(x_1\))
(y−2)=3(x−1) ➜ The slope is 3.
Answer:
m = 3
Step-by-step explanation:
to solve this you should first remove and or distribute the parenthesis
y - 2 = 3x - 3
now add 2 to both sides
y = 3x - 1
the equation of a line in slope intercept is y = mx + b
m is the slope
we can see that that is 3
so the slope is 3

Answer:
The equation that matches the function shown is option;
C. \(y = sin\left (\dfrac{1}{2} \cdot x\right)\)
Step-by-step explanation:
The given graph of the function is a sinusoidal graph
The values of 'x' and 'y' coordinates at the maximum, x-intercept and minimum points are given as follows;
x, \({}\) y
0 \({}\) 0
π \({}\) 1
2·π \({}\) 0
3·π \({}\) -1
4·π \({}\) 0
We note that sin(π/2) = 1, sin(π) = 0 sin(3·π/2) = -1, and sin(4·π/2) = sin(2·π) = 0
Therefore;
y = the sine of half the x-value
Which is presented as follows;
\(y = sin\left (\dfrac{1}{2} \cdot x\right)\).
Arrange the given steps in the correct order to prove that 3^n < n! is an integer greater than 6, using mathematical induction.
Suppose that for some k>6, 3^k
3^k+1 < (k+1)!
3^k+1 < (k+1) * 3^k
For n = 7.3^7 = 2187 < 7! + 5040
3^k=1 < (k+1) * k!
3^k+1 = 3 * 3^k
Answer:
Step-by-step explanation:
To prove that 3^n < n! for every integer n > 6 using mathematical induction, follow these steps:
1. Base case: Verify the statement for n = 7. We have \(3^{7}= 2187 < 7!=5040\) , so the statement is true for n = 7.
2. Inductive hypothesis: Assume that for some integer k > 6, \(3^{k} < k!\)holds true.
3. Inductive step: Prove the statement for n = k + 1. We want to show that 3^(k+1) < (k+1)!.
4. Multiply both sides of the
by 3. This gives \(3^{k+1} < (k+1)!\)5. We know that \(3^k < k!\). Since k > 6, we have k + 1 > 3. Multiply both sides of the inequality \(3^k < k!\) by (k + 1) to get (k+1) * 3^k < (k+1) * k!.
6. Using the result from step 4, substitute 3^(k+1) in the inequality: 3^(k+1) < (k+1) * k!.
7. Recognize that (k+1) * k! = (k+1)!. 8. Combine steps 6 and 7 to conclude that 3^(k+1) < (k+1)!. Since the statement holds true for n = 7 and assuming it is true for k implies that it is true for k + 1, we have proven that 3^n < n! for every integer n > 6 using mathematical induction.

What are the measures of angles B and D?
A. ∠B = 55°, ∠D = 55°
B. ∠B = 55°, ∠D = 125°
C. ∠B = 97°, ∠D = 97°
D. ∠B = 83°: ∠D = 97°
Answer:
One basic property of a parallelogram is that opposite angles have the same value. Hence angle B = angle D. (2n+15°) = (3n-5°). Then have one side for the unknown. The equation will be 3n=2n+15°+5°. To get the n, simplify the equation: 3n-2n = 20° or n = 20°. Afterwards substitute the value of n to the angles. Angle B = (2(20)+15), Angle D = (3(20)-5). Lastly, simplify the equations. Angle B = (40+15°) = 55° and Angle D = (60-5°)=55°. Therefore the value of angles B & D are both 55°.

the main limitation of which type of study design is that researchers cannot infer the temporal sequence between exposure and disease when the exposure is a changeable characteristic?
The main limitation of a cross-sectional study design is that researchers cannot infer the temporal sequence between exposure and disease when the exposure is a changeable characteristic.
Cross-sectional studies are observational studies that measure the prevalence of a disease or health outcome at a specific point in time and assess the association between the outcome and exposure to certain risk factors. However, because the data is collected at a single time point, it is impossible to determine the order of events between exposure and outcome. This is particularly problematic when the exposure is a changeable characteristic such as diet or lifestyle habits. In such cases, it is difficult to determine whether the exposure caused the outcome or whether the outcome led to changes in exposure. Despite this limitation, cross-sectional studies can still provide valuable information about the prevalence and distribution of diseases and risk factors in a population.

One day, a sprinter runs the 100 m dash 24 times, for a total distance of 24 00 m. how many kilometers did the sprinter run?
The total distance that was covered by the sprinter in Kilometers is:
2.4 KmHow much is the total distance covered?
To obtain the total distance covered by the sprinter, we need to first realize that 1 Km is equal to 1000 meters. That said, the question above requires us to change 2400 meters to kilometers.
Thus we will have:
2400 Meters * 1 km / 1000 meters
= 2.4 km
So, the total distance covered by the sprinter in kilometers is 2.4

a plumber charges $55 for one hour of work, $90 for 2 hours, $125 for 3 hours, which function represents the sequence of hourly charges?
By using what we know about linear functions, we will see that the function that represents the hourly charges is y = $35*x + $20
We assume that the function that we must find is a linear function of the form:
y = a*x + b
Where a is the slope and b is the y-intercept.
x would be the time worked and y the corresponding price.
Then we have 3 points on the line:
(1, $55)(2, $90)(3, $125).We know that for a line that passes through two points (x₁, y₁) and (x₂, y₂), the slope is given by:
\(a = \frac{y_2 - y_1}{x_2 - x_1}\)
If here we use the two first points (or any two that you want) we will find the slope:
\(a = \frac{\$ 90 - \$ 55}{2 - 1} = \$35\)
Then the line is something like:
y = $35*x + b
To find the value of b we can use any one of the given points, for example the first one (1, $55) means that when x = 1, we must have y = $55.
Replacing that we get:
$55 = $35*1 + b
$55 - $35 = b = $20
Then the function is just:
y = $35*x + $20

Answer:
x = 20
Step-by-step explanation:
The triangle has 2 congruent sides and is therefore isosceles with 2 congruent base angles, both 3x + 8
5x + 12 and 3x + 8 lie on a straight line and sum to 180° , that is
5x + 12 + 3x + 8 = 180
8x + 20 = 180 ( subtract 20 from both sides )
8x = 160 ( divide both sides by 8 )
x = 20

A pendulum swings 80cm on its first swing,76cm on its second swing, 72.2 cm on its third swing, and 68.59 cm on its fourth swing what is the distance of the swing at the tenth swing?
The distance of the swing of a pendulum decreases by a constant amount each swing. To find the distance of the swing at the tenth swing, you can use the formula:
distance at nth swing = distance at first swing * (1 - decay factor)^(n-1)
Where decay factor is the fractional decrease in distance per swing. In this case, the decay factor is (80 - 76) / 80 = 0.05. Plugging this into the formula above, we get:
distance at 10th swing = 80 * (1 - 0.05)^9 = 53.78 cm
So the distance of the swing at the tenth swing is approximately 53.78 cm.

Number of homeowners planted exactly two of the three vegetables is 434
|P| = 240, |S| = 165, |G| = 142.
|P ∩ S ∩ G| = 36, |P ∩ S| = 0, |P ∩ G| = 0, |S ∩ G| = 0.
Where, P is the set of homeowners who planted peppers, S is the set of homeowners who planted spinach, and G is the set of homeowners who planted garlic
According to inclusion-exclusion
|P∪∪ G| = |P|+|S|+ |G|-|P ∩ S|-|P ∩ G|-|S ∩ G|+ |P∩S∩G|
= 240 + 165 + 142 - 0 - 0 - 0 + 36
= 583
|X| = |P ∩ S' ∩ G'| + |P' ∩ S ∩ G'| + |P' ∩ S' ∩ G|
Substitute the values
= 82 + 45 + 22
= 149
|Y| = 583 - 149

a) The investigator who takes a sample of 1,000 men age 18-24 is more likely to get a bigger average for the heights of the men in his sample.
This is because a larger sample size tends to provide a better estimate of the population mean, and thus, the sample mean tends to be closer to the true population mean.
b) The investigator who takes a sample of 100 men age 18-24 is more likely to get a bigger SD for the heights of the men in his sample.
This is because a smaller sample size tends to provide a less accurate estimate of the population SD, and thus, the sample SD tends to be further from the true population SD.
However, if the population SD is known, then the sample size does not affect the SD of the sample mean.

Since the perimeter of one equilateral triangle is 21 inches, each side of the triangle has a length of 21/3 = 7 inches.
Since the hexagon consists of six equilateral triangles, it will have six sides, each of length 7 inches. Therefore, the perimeter of the hexagon is given by:
