Prove that these two statements have the same slope: y = -3x - 8 and 3x + y = -8

Answer:

To determine the location of point H, we need to first find the length of the three sides of the fenced area using the given points E, F, and G.

The length of EF is:

sqrt[(3-1)^2 + (5-5)^2] = 2 units

The length of FG is:

sqrt[(6-3)^2 + (1-5)^2] = sqrt(25) = 5 units

The length of EG is:

sqrt[(6-1)^2 + (1-5)^2] = sqrt(20) = 2sqrt(5) units

The total length of the three sides is:

2 + 5 + 2sqrt(5) = 7 + 2sqrt(5) units

Since Landon has 16 units of fencing, he needs to find a point H such that the length of the fourth side of the fenced area (EH) is:

16 - (7 + 2sqrt(5)) = 9 - 2sqrt(5) units

Let's assume that point H has coordinates (x, y). Then, we can use the distance formula to find the length of EH:

sqrt[(x-1)^2 + (y-5)^2] = 9 - 2sqrt(5)

Squaring both sides and simplifying, we get:

(x-1)^2 + (y-5)^2 = 81 - 36sqrt(5) + 20

(x-1)^2 + (y-5)^2 = 101 - 36sqrt(5)

Now, we can plug in the coordinates of each of the answer choices and see which one satisfies this equation:

For (0, 1):

(0-1)^2 + (1-5)^2 = 16, which is not equal to 101 - 36sqrt(5)

For (0, -2):

(0-1)^2 + (-2-5)^2 = 65, which is not equal to 101 - 36sqrt(5)

For (1, 1):

(1-1)^2 + (1-5)^2 = 16, which is not equal to 101 - 36sqrt(5)

For (1, -2):

(1-1)^2 + (-2-5)^2 = 65, which is equal to 101 - 36sqrt(5)

Therefore, the answer is (1, -2), and Landon can place point H at coordinates (1, -2) to fence in the dog park without having to buy more fencing.

Hence, the shape is rectangular prism with the dimensions 10mm, 8mm, and 8mm has a surface area of 448mm2.

We must first calculate the surface area of each face of a rectangular prism with 10mm, 8mm, and 8mm measurements before adding them all up.

The top and bottom faces, which are both rectangles with measurements of 10 mm by 8 mm, are first measured for area:

Area of the top and bottom faces is equal to 2 (10 x 8 mm) or 160 mm2.

The area of the front and back faces, which are both rectangles measuring 10 mm by 8 mm, is then determined: Area of the front and back faces is equal to 128mm2 (8mm x 8mm).

The area of the two side faces, which are both rectangles with dimensions of 10 mm by 8 mm, is then determined: Area of the side sides is equal to 2 (10mm x 8mm) = 160mm2.

We add up the areas of all the faces to determine the overall surface area:

Whole surface area equals the sum of the areas of the top and bottom faces, the front and back faces, and the side faces.

Surface area total = 160 mm2 + 128 mm2 + 160 mm2

448 mm2 is the total surface area.

If the mean of x, y and z is 88 1/3% of 360. The range of x, y and z is 2,852.

To solve this problem, we need to use the given ratios and proportions to find the values of x, y, and z, and then use the given mean to find their range.

From the first ratio, we have:

x:y = 5:3

This can be written as:

x = (5/3) * y

Substituting this value of x into the second ratio, we get:

y:2 = 11:6

Multiplying both sides by 3, we get:

3y = 22

y = 22/3

Substituting this value of y into the equation for x, we get:

x = (5/3) * (22/3) = 110/9

To find z, we can use the mean of x, y, and z:

(1/3)(x + y + z) = (8/3) * 360

x + y + z = 2880

Substituting the values we found for x and y, we get:

(110/9) + (22/3) + z = 2880

Multiplying both sides by 9, we get:

110 + (66/3) + 9z = 25920

110 + 22 + 9z = 25920

9z = 25788

z = 2864

Therefore, the values of x, y, and z are:

x = 110/9

y = 22/3

z = 2864

To find the range, we need to subtract the smallest value from the largest value:

Range = z - x = 2864 - (110/9) = 2,852

This inequality can be read as "the sum of 1.2 and m is less than or equal to 5.5."

To solve for m, you need to isolate it on one side of the inequality symbol.

1.2 + m ≤ 5.5

Subtract 1.2 from both sides:

m ≤ 5.5 - 1.2

Simplify:

m ≤ 4.3

Therefore, the solution to the inequality is m ≤ 4.3.

Step-by-step explanation:

c = 3.

a) A is linearly dependent for any value of c because the vectors are not linearly independent.

This means that one of the vectors can be written as a linear combination of the others.

For example, the vector (1,2,c) can be written as (2,2,0) + (-1,0,c-0) = (1,2,c).

This means that the set of vectors is linearly dependent.

b) For c = 0, Vector (A) is the set of all linear combinations of the vectors (2,2,0), (1,2,0), (0,0,0), and (1,0,0).

This means that Vect (A) is the set of all points in the xy-plane, or the set of all vectors in R^2.c).

To find all the values of c for which (4,1,3) is in Vect (A),

we need to solve the equation (4,1,3) = a(2,2,0) + b(1,2,c) + d(0,0,c) + e(1,0,0) for the scalars a, b, d, and e.

This gives us the system of equations:4 = 2a + b + e1 = 2a + 2b3 = bc + dc.

Solving this system of equations gives us the values of a, b, d, and e in terms of c.

We can then use these values to find the values of c for which (4,1,3) is in Vect (A).

After solving the system of equations, we find that c = 3 and a = 1, b = -1, d = 0, and e = 2.

Therefore, the value of c for which (4,1,3) is in Vect (A) is c = 3.

This is the final factored form of the original expression. = (4x^(2)-x-265)/((4(x-9)(x+6)))

To find the factored form of (x^(2)-64)/(x^(2)-3x-54)-(x^(2)-81)/(4x^(2)-12x-216), we will first factor each of the expressions in the numerator and denominator.

The factored form of x^(2)-64 is (x+8)(x-8).

The factored form of x^(2)-3x-54 is (x-9)(x+6).

The factored form of x^(2)-81 is (x+9)(x-9).

The factored form of 4x^(2)-12x-216 is (2x-18)(2x+12).

Now, we can substitute the factored forms back into the original expression:

((x+8)(x-8))/((x-9)(x+6))-((x+9)(x-9))/((2x-18)(2x+12))

Next, we will simplify the expression by canceling out common factors:

((x+8)(x-8))/((x-9)(x+6))-((x+9)(x-9))/(2(x-9)(2x+12))

= ((x+8)(x-8))/((x-9)(x+6))-(1/2)((x+9)/(2x+12))

= ((x+8)(x-8))/((x-9)(x+6))-(1/2)((x+9)/(2(x+6)))

= ((x+8)(x-8))/((x-9)(x+6))-(1/4)((x+9)/(x+6))

Now, we will find a common denominator and combine the two fractions:

= ((4(x+8)(x-8))-(x+9))/((4(x-9)(x+6)))

= ((4x^(2)-256)-(x+9))/((4(x-9)(x+6)))

= (4x^(2)-x-265)/((4(x-9)(x+6)))

The area of the triangle with the given vertices is 4.47.

To find the area of the triangle with the given vertices, we can use the formula:
Area = (1/2) * |(B-A) x (C-A)|
Where "x" represents the cross product of two vectors.
First, we need to find the vectors B-A and C-A:
B-A = (1-5, 1-(-1), 0-(-2)) = (-4, 2, 2)
C-A = (3-5, 2-(-1), -1-(-2)) = (-2, 3, 1)
Next, we need to find the cross product of these two vectors:
(B-A) x (C-A) = (2*1 - 2*3, 2*(-2) - (-4)*1, (-4)*3 - 2*(-2)) = (-4, 0, -8)
Finally, we can find the area of the triangle by plugging in the values into the formula:
Area = (1/2) * |(-4, 0, -8)|
Area = (1/2) * √((-4)^2 + 0^2 + (-8)^2)
Area = (1/2) * √(80)
Area = (1/2) * 8.94
Area = 4.47

23) The equation for the hyperbola is (y-2)^2/9 - (x-1)^2/16 = 1.

24) The equation for the circle is (x+1)² + (y-3)² = 17.

23. The equation for a hyperbola with center (h,k) and vertices (h,k+a) and (h,k-a) is:

(y-k)²/a²- (x-h)²/b² = 1

In this case, the center is (1,2), so h = 1 and k = 2. The vertices are (1,5) and (1,-1), so a = 3. To find b, we can use the fact that c^2 = a^2 + b^2, where c is the distance from the center to the foci. The foci are (1,7) and (1,-3), so c = 5. Therefore:

5² = 3² + b²

b² = 25 - 9

b² = 16

b = 4

So the equation for the hyperbola is:

(y-2)^2/3^2 - (x-1)^2/4^2 = 1

(y-2)^2/9 - (x-1)^2/16 = 1

24. The equation for a circle with center (h,k) and radius r is:

(x-h)² + (y-k)² = r²

In this case, the center is (-1,3), so h = -1 and k = 3. To find the radius, we can use the distance formula with the center and the point (3,2):

r = sqrt((3-(-1))² + (2-3)²

r = sqrt(4² + (-1)²)

r = sqrt(16 + 1)

r = sqrt(17)

So the equation for the circle is:

(x-(-1))² + (y-3)² = (sqrt(17))²

(x+1)² + (y-3)² = 17

With an APR of 6.75% over a 20-year period, the annual payment for the loan will be $81,371.52.

To find the annual payment for the loan, we need to first find the total cost of the land and the amount of the loan.

Total cost of the land = 245 acres x $4,700/acre = $1,151,500

Down payment = 25% of total cost = 0.25 x $1,151,500 = $287,875

Loan amount = Total cost - Down payment = $1,151,500 - $287,875 = $863,625

Next, we need to use the loan amount, APR, and loan term to find the annual payment. We can use the following formula:

Annual payment = (Loan amount x APR) / (1 - (1 + APR)^(-Loan term))

Plugging in the values we have:

Annual payment = ($863,625 x 0.0675) / (1 - (1 + 0.0675)^(-20))

Annual payment = $58,294.69 / (1 - 0.2837)

Annual payment = $58,294.69 / 0.7163

We can use LCM to find a common denominator for these fractions. The LCM of 70, 2, and 5 is 70 x 2 x 5 = 700. The result of the expression is approximately 29.3885.

To solve this problem using LCM, we first need to convert all the mixed numbers to improper fractions:

Three and three seventieths = (3 x 70 + 3) / 70 = 213 / 70

Six and a half = (6 x 2 + 1) / 2 = 13 / 2

Nine and three fifths = (9 x 5 + 3) / 5 = 48 / 5

Now we can use LCM to find a common denominator for these fractions. The LCM of 70, 2, and 5 is 70 x 2 x 5 = 700.

We can then convert each fraction to an equivalent fraction with denominator 700:

213/70 = 3.042857... ≈ 3.043

13/2 = 455/70 = 6.5

48/5 = 192/20 = 96/10 = 480/50

Now we can substitute these equivalent fractions into the original expression and simplify:

3.043 × 6.5 + 480/50 = 19.7885... + 9.6 = 29.3885.

LCM stands for the "Least Common Multiple" and is a mathematical concept used to find the smallest multiple that two or more numbers have in common. In other words, it is the smallest positive integer that is divisible by all the given numbers.

To find the LCM of two or more numbers, we can start by finding their prime factorization.
