A line passes through points (-3, 1) and (2, - 3) What is the slope of the line parallel to the graph?​

Answers

Answer:

To find the slope of the line passing through (-3, 1) and (2, -3), we can use the slope formula:

slope = (y2 - y1) / (x2 - x1)

where (x1, y1) = (-3, 1) and (x2, y2) = (2, -3).

slope = (-3 - 1) / (2 - (-3))

= -4 / 5

So, the slope of the line passing through (-3, 1) and (2, -3) is -4/5.

To find the slope of a line parallel to this line, we need to remember that parallel lines have the same slope. Therefore, the slope of the parallel line is also -4/5.


Points A and B have coordinates (-5, 16) and (3,12) respectively.
C is the point that lies of the way along AB. Find the coordinates of C.

Answers

Answer:

the coordinates of point C are approximately (0.56, 17.72)

Step by step Explanation:

To find the coordinates of point C, we need to find its distance from point A as a fraction of the distance between points A and B, and then use that fraction to find the coordinates of C.

Let's call the distance between points A and B "d". We can find the distance using the distance formula:

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

where (x₁, y₁) and (x₂, y₂) are the coordinates of points A and B, respectively. Plugging in the values, we get:

d = √[(3 - (-5))² + (12 - 16)²] = √64 + 16 = √80

Now, let's call the fraction of the distance from A to B that C lies on "f". We know that C is closer to A than to B, so 0 ≤ f ≤ 1. We can find f using the formula:

f = AC/AB

where AC is the distance from A to C. We can use the distance formula again to find AC:

AC = √[(x - (-5))² + (y - 16)²]

where (x, y) are the coordinates of point C. We also know that C is on the line segment AB, so its x-coordinate must satisfy:

(x - (-5))/(3 - (-5)) = f

Simplifying, we get:

(x + 5)/8 = f

Solving for x, we get:

x = 8f - 5

Similarly, we can use the y-coordinate of C to form another equation:

(y - 16)/(12 - 16) = f

Simplifying and solving for y, we get:

y = 4(1 - f) + 16 = 20 - 4f

Now we have expressions for x and y in terms of f. We can substitute these into the expression for AC:

AC = √[(8f - 5 - (-5))² + (20 - 4f - 16)²] = √[64f² - 64f + 100]

Finally, we can plug in our expressions for AC and AB to solve for f:

f = AC/AB = √[64f² - 64f + 100]/√80

Squaring both sides and simplifying, we get a quadratic equation:

64f² - 64f + 100 = 80f²

16f² + 64f - 100 = 0

Dividing both sides by 4 and using the quadratic formula, we get:

f = (-64 ± √(64² - 4(16)(-100))) / 2(16)

f ≈ -0.32 or f ≈ 1.57

Since 0 ≤ f ≤ 1, the valid solution is:

f ≈ 0.57

Now we can use this value to find the coordinates of C:

x = 8f - 5 ≈ 0.56

y = 20 - 4f ≈ 17.72

Therefore, the coordinates of point C are approximately (0.56, 17.72)

Answers

Answer:

(a) a = 60

(b) a = 75

(c) a = 108

All are corresponding.

Step-by-step explanation:

These questions involve the laws of angles on parallel lines. I like to call them "C", "F" and "Z" angles.

(a) is an example of a "Z" angle. By observation you can see that a is equivalent to the 60 degree angle as they are both internal angles of the "Z" shape created by a line intersecting the pair of parallel lines.

(b) is an example of an "F" angle. a is equivalent to the 75 degree angle because the straight line intersects the pair of parallel lines at the same angle.

(c) is another example of an "F" angle. a is equivalent to the 108 degree angle for the same reason as in question (b).

All the answers are corresponding angles because they are the same as the original. An alternate angle would be where your angle and the original sum to 180, as would be the case in "C" angles (also known as "co-interior" angles).

(a) Show the following o-fields are equal to each other: i. B= o({(-20,x); r < R}); ii. B2 = o({(-0,2); 2 € R}); [Note either of them can be taken as the definition of the Borel sigma field on the real line.]

Answers

The following o-fields are equal to each other because they both represent the Borel sigma field on the real line:
i. B= o({(-20,x); r < R})
ii. B2 = o({(-0,2); 2 € R})

Note that the Borel sigma field on the real line is the smallest sigma field containing all the open intervals on the real line. This means that any set that can be constructed from countable unions, intersections, and complements of open intervals is in the Borel sigma field.

In the first o-field, B= o({(-20,x); r < R}), the set {(-20,x); r < R} is an open interval on the real line, so it is in the Borel sigma field. Similarly, in the second o-field, B2 = o({(-0,2); 2 € R}), the set {(-0,2); 2 € R} is also an open interval on the real line, so it is also in the Borel sigma field.

Since both o-fields contain sets that are in the Borel sigma field, they are both equal to the Borel sigma field on the real line. Therefore, B= o({(-20,x); r < R}) = B2 = o({(-0,2); 2 € R}).

LINEAR EQUATIONS Multiplicative property of Solve for x 24=(3)/(4)x Simplify your answer as much as x

Answers

Using multiplicative property of equations, the solution to the equation is x = 32.

The multiplicative property of equations states that if you multiply both sides of an equation by the same number, the equation will still be true.

In this case, we can use the multiplicative property to solve for x by multiplying both sides of the equation by (4/3) to cancel out the fraction on the right side of the equation.

24 = (3/4)x

(4/3)(24) = (4/3)(3/4)x

32 = x

y = 4* Reflect it across the y-axis, translate it to the right 3 units, and vertically stretch it by a factor of 2

Answers

y = -2x + 14

To reflect the equation y = 4 across the y-axis, we need to change the sign of the x-term. Since there is no x-term in the original equation, we can simply add a negative x-term to get the reflected equation: y = -x + 4.

Next, to translate the equation to the right 3 units, we need to subtract 3 from the x-term. This gives us the translated equation: y = -(x - 3) + 4.

Finally, to vertically stretch the equation by a factor of 2, we need to multiply the entire equation by 2. This gives us the final transformed equation: y = 2(-x + 3) + 8.

In summary, the equation y = 4 reflected across the y-axis, translated to the right 3 units, and vertically stretched by a factor of 2 is y = -2x + 14.

Let B1 be the basis {(1,2,3),(2,−1,2)}={u1,u2} and B2 be the basis {(0,5,4),(1,−8,−5)}={v1,v2}. Show that these two bases span the same subspace of R3

Answers

The two bases B1 and B2 span the same subspace of R3.

Let B1 be the basis {(1,2,3),(2,−1,2)}={u1,u2} and B2 be the basis {(0,5,4),(1,−8,−5)}={v1,v2}. We want to show that these two bases span the same subspace of R3.

To do this, we need to show that any vector in the subspace spanned by B1 can also be written as a linear combination of vectors in B2, and vice versa.

Let x be a vector in the subspace spanned by B1. Then x = a*u1 + b*u2 for some scalars a and b. Substituting the values of u1 and u2, we get:

x = a*(1,2,3) + b*(2,−1,2)

= (a+2b, 2a-b, 3a+2b)

Now we want to express x as a linear combination of v1 and v2:

x = c*v1 + d*v2

= c*(0,5,4) + d*(1,−8,−5)

= (d, 5c-8d, 4c-5d)

Setting the two expressions for x equal to each other, we get the following system of equations:

a+2b = d

2a-b = 5c-8d

3a+2b = 4c-5d

Solving this system of equations, we can find values of c and d that satisfy the equations. This shows that any vector in the subspace spanned by B1 can also be written as a linear combination of vectors in B2.

Similarly, we can show that any vector in the subspace spanned by B2 can also be written as a linear combination of vectors in B1.

Therefore, the two bases B1 and B2 span the same subspace of R3.

The amount of money in the account after 9 years is $2549.68.

The formula A=P(1+(r)/(n))^(nt) is used to calculate the amount of money in an account after a certain amount of time, given the principal amount (P), the interest rate (r), the number of times interest is compounded per year (n), and the number of years (t).

To find A when P=2000, r=3%, n=12, and t=9, we can plug these values into the formula and simplify:

A = 2000(1+(0.03)/(12))^(12*9)

A = 2000(1+0.0025)^(108)

A = 2000(1.0025)^(108)

A = 2000(1.2748)

What is equation?

An equation is a mathematical statement that two expressions are equal. It consists of two expressions separated by an equals sign (=), and expresses a relationship between the two expressions. Equations can be used to represent a variety of problems and can help solve real-world problems. For example, an equation can be used to calculate the amount of money someone will have after a certain period of time, or to calculate the distance between two points.

In order to answer this question, we must first solve the equation. 9t6-14+³ +4+- 1 = 0 can be written as 9t6 - 11 + 4 - 1 = 0. After simplifying, this equation becomes 9t6 - 7 = 0, which can be further simplified to t6 = 7. Taking the sixth root of both sides, we can determine that t = √7. Therefore, there is 1 solution to this equation.

Answer:

B. (-2,2)

Step-by-step explanation:

Determine which numbers in the set are solutions of the equation. n-7=12;{17,19,21}

Answers

The number 19 is the solution of the equation n-7=12.

How do we find the solution?

The equation given is n-7=12. To find the solution, we need to isolate the variable n on one side of the equation. We can do this by adding 7 to both sides of the equation. This gives us:

n-7+7=12+7

Simplifying the equation gives us:

n=19

Now, we can check which numbers in the set {17,19,21} are solutions of the equation. The only number that satisfies the equation is 19. Therefore, the solution of the equation is 19.

Answer: The number 19 is the solution of the equation n-7=12.

During the summer, Olympic swimmer Adam Johnson swims every day. On sunny summer days, he goes to an outdoor pool, where he may swim for no charge. On rainy days, he must go to a domed pool. At the beginning of the summer, he has the option of purchasing a $15 season pass to the domed pool, which allows him use for the entire summer. If he doesn't buy the season pass, he must pay $1 each time he goes there. Past meteorological records indicate that there is a 60% chance that the summer will be sunny (in which case there is an average of 6 rainy days during the summer) and a 40% chance the summer will be rainy (an average of 30 rainy days during the summer).
Before the summer begins, Adam has the option of purchasing a long-range weather forecast for $1. The forecast predicts a sunny summer 80% of the time and a rainy summer 20% of the time. If the forecast predicts a sunny summer, there is a 70% chance that the summer will actually be sunny. If the forecast predicts a rainy summer, there is an 80% chance that the summer will actually be rainy. Assuming that Adam's goal is to minimize his total expected cost for the summer, what should he do? Also find EVSI and EVPI

Answers

Adam should purchase the long-range weather forecast for $1. By doing so, he will have the best chance of minimizing his total expected cost for the summer.

The expected value of the sample information (EVSI) is the expected cost if Adam does not purchase the forecast and goes with the meteorological records, which is $16.6 ($15 for the season pass plus an average of $1.6 per rainy day).

The expected value of perfect information (EVPI) is the expected cost if Adam purchases the forecast and uses it to make the decision, which is $15.6 ($15 for the season pass plus an average of $0.6 per rainy day).

Thus, purchasing the long-range weather forecast is the best decision for Adam, as it will save him $1 in expected costs and allow him to minimize his total expected cost for the summer.
