Find the equation of the line that satisfies the conditions given in each of the following: 1. Through (3, 2) and (5, 7) 2. Through (-3, 4), m = 2 3. m = -3, b = 5 4. x-intercept = 3, y-intercept
Answers
The equation of each line that satisfies the given conditions are:
1. y - 2 = 5/2(x - 3)
2. y - 4 = m(x + 3)
3. y = -3x + 5
What is the Equation of a Line?If we know the slope (m) and the y-intercept (b) of a line, we can write the equation of the line as y = mx + b in slope-intercept form.If we know the point (a, b) and the slope (m) of the line, we can write the equation of the line in point-slope form as y - b = m(x - a).1. Given the points, (3, 2) and (5, 7), find the slope (m):
Slope (m) = change in y / change in x = (7 - 2)/(5 - 3)
m = 5/2
Write the equation in point-slope form by substituting m = 5/2 and (a, b) = (3, 2) into y - b = m(x - a):
y - 2 = 5/2(x - 3)
2. Given:
A point = (-3, 4)
Slope (m) = 2
Substitute (a, b) (-3, 4), and m = 2 into y - b = m(x - a):
y - 4 = m(x + 3) [equation of the line]
3. Given:
Slope (m) = -3
Y-intercept (b) = 5

Solve each equation by using the square root property. 2x^2–3=7.
Answers
Explanation
\(2x^2-3=7\)
Step 1
add 3 in both sides
\(\begin{gathered} 2x^2-3=7 \\ 2x^2-3+3=7+3 \\ 2x^2=10 \\ \end{gathered}\)Step 2
divide both sides by 2
\(\begin{gathered} 2x^2=10 \\ \frac{2x^2}{2}=\frac{10}{2} \\ x^2=5 \\ \end{gathered}\)Step 3

A. None
B. One
C. Two
D. Three
E. Four
Answers
2 numbers are possible, 64 and 96.
Therefore, option (c) is correct.
We can solve this question using trial and error method.
Given, an integer n's length is the number of prime factors whose product is equal to n.
Since we have to find a two-digit positive integer whose length is 6:
Let us take 2 as our first prime factor (as 2 is a prime number)
2*2*2*2*2*2 = 64.
Here, we have got 1 number with length 6.
Let us take 3 as our 2nd prime factor (as 3 is a prime number).
3*3*3*3*3*3 = 96.
Here, we have got 2 numbers with length 6.
Now, let us try:
2*2*2*2*2*3 = 144
Since we need only 2 digit numbers, this is not possible.

Interior angle refers to the angle inside a polygon that is formed by two of its adjacent sides. The sum of the measures of the interior angles of a polygon is given by the equation:
180°(n - 2)
where n is the number of sides
An octagon is a polygon that has 8 vertices and 8 sides. The sum of the measures of the interior angles of an octagon is:
180°8 - 2) = 180°6) = 1080°
On the other hand, a hexagon is a polygon that has 6 vertices and 6 sides. The sum of the measures of the interior angles of an octagon is:
180°6 - 2) = 180°4) = 720°
Subtracting the sum of the interior angles of the two polygons,

The straight-line distance between Akira's house and Cooper's house is 6.13 kilometers (rounded to the nearest tenth)
Given that,To get from home to his friend Akira's house, Jaden would have to walk 2.8 kilometers due east.The straight-line distance between Akira's house and Cooper's house is given by the distance between two points in a coordinate plane. Let the home be the origin (0, 0) of the coordinate plane and Akira's house be represented by the point (2.8, 4.7). Similarly, let Cooper's house be represented by the point (8.3, 7.4).The distance formula between the two points (2.8, 4.7) and (8.3, 7.4) is given by:distance = √[(8.3 - 2.8)² + (7.4 - 4.7)²]= √[5.5² + 2.7²]= √(30.25 + 7.29)= √37.54= 6.13 km (rounded to the nearest tenth)

Based on a life insurance company's past data, each year an average of 1/90 policy holders
make a claim of $250; 1/100 policy holders make a claim of $12,000, and 1/400 make a claim
of $17,000. What would the insurance company have to charge per policyholder to break
even?
Answers
Answer:
1. The expected pay-out on each policy is 250 * 1/90 + 12000 * 1/100 + 17000 * 1/400 = $165. So that's what the premium would have to be in order to get a profit of 0.
2. The profit per policy is the premium the company receives minus the expected payout = 350 - 165 = $185.
3. The expected profit on 375 policies would be 375 * 185 = $69375

26,30,45,43,26,14,28,33,56,29,what is the mean absolute deviation of the data set
Answers
Answer: 9.
Step-by-step explanation: To find the MAD (mean absolute deviation) we need to do the following steps below:
1. Find the mean.
2. Subtract the mean from the numbers of the data.
3. Add the results and divide to find the MAD.
The steps are done below:
1. Find the mean: In order to find the mean of a data set, you need to add all the numbers and then divide the result by how many numbers there are in the data set. In this problem, there are 10 numbers in the data set, so whatever we get for adding the data numbers together needs to be divided by 10.
26 + 30 + 45 + 43 + 26 + 14 + 28 + 33 + 56 + 29 = 330.330 / 10 = 33.2. Subtract the mean from the numbers of the data: To do this, we need to subtract 33 from all the numbers on the data. The following is done below. (*Note: You may notice that most equations like 26 - 33 would be in the negatives, but for data, it has to be positive. If you ever run into a situation like that, you simply just make it positive).
26 - 33 = 7.30 - 33 = 3.45 - 33 = 12.43 - 33 = 10.26 - 33 = 7.14 - 33 = 19.28 - 33 = 5.33 - 33 = 0.56 - 33 = 23.29 - 33 = 4.3. Add the results and divide to find the MAD: Now that we have the results, we add those numbers and then divide to find the MAD. Make sure that when you divide that it is 10 that you're dividing because once again, there are 10 numbers for the results.
7 + 3 + 12 + 10 + 7 + 19 + 5 + 0 + 23 + 4 = 90.90 / 10 = 9.Therefore, 9 is the MAD.

What is an emergency fund?An emergency fund is separate savings account to cater to the following unplanned situations:
Unplanned expensesAn illnessThe loss of a job.It is prudent to have up to 6 months' salary in an emergency fund.
Monthly salary = $2,650
Monthly expenses = $1,465
Emergency fund = 30% of expenses
= $440 ($1,465 x 30%)
Retirement savings = 20% of the salary
= $530 ($2,650 x 20%)
Total amount to set aside each month = $970 ($440 + $530)

Write an equation in point-slope form for the line that has a slope of 4/5 and contains the point (−5,−3).
Answers
Explanation:
The point slope formula states: (y-y1)=m(x-x1)
In this formula M is the slope and (y1 and x1) are the points the line passes through.
When substituting the values from the problem you get
(y-3)=4/5(x+5)
The equation in point-slope form for the line that has a slope of 4/5 and contains the point (−5,−3) is; y = 4x/5 + 7
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
Which is the required equation of a line in a point-slope form
Where x₁ - x coordinate, y₁ - y coordinate, m - slope
Point (−5,−3)
Then Slope m =4/5
Now Write the equation as;
(y-3)=4/5(x+5)
y = 4x/5 + 7
Hence, the equation in point-slope form is; y = 4x/5 + 7

The volume of the solid is 250r³ when the base of s is a circular disk with radius 5r.
Given that,
We have to discover the described solid's volume, v. The parallel cross-sections perpendicular to the base of s are squares, and the base of s is a circular disk with radius 5r.
We know that,
A cylinder is a solid with square cross sections parallel to the bases and circular bases. Its height is equal to the base circle's diameter.

The correct statement regarding the angle measures is given as follows:
m < 1 + m < 4 > m < 3.
How to obtain the angle measures?The given angle measure is as follows:
m < 3 = 119º.
Angles 3 and 4 form a linear pair, meaning that they are supplementary, that is, the sum of their measures is of 180º.
Hence the measure of angle 4 is given as follows:
m < 4 + m < 3 = 180º.
m < 4 = 180º - 119º
m < 4 = 61º.
Angles 1 and 4 are opposite by the same vertex, hence they are congruent, thus the measure of angle 1 is given as follows:
m < 1 = m < 4
m < 1 = 61º.
Hence:
m < 1 + m < 4 = 2 x 61
m < 1 + m < 4 = 122º
122º > 119º
m < 1 + m < 4 > m < 3.
