Answer:

AB and CD.

Step-by-step explanation:

To check if two sides of a quadrilateral are congruent, we need to find the length of each side. We can use the distance formula to calculate the length of each side:

AB = √[(1 - 4)^2 + (4 - 1)^2] = √(9 + 9) = 3√2

BC = √[(5 - 1)^2 + (1 - 4)^2] = √(16 + 9) = √25 = 5

CD = √[(1 - 1)^2 + (-2 - 1)^2] = √9 = 3

AD = √[(-3 - 1)^2 + (1 - (-2))^2] = √(16 + 9) = √25 = 5

Therefore, AB and CD have the same length and are congruent, while BC and AD have the same length and are congruent.

So the correct answer is AB and CD.

Harbin was colder than Beijing on that particular day in December because the temperature difference between the two cities was -6ºC.

To figure out which city was colder, we need to compare the difference between the temperatures of the two cities. The temperature difference is the numerical value we get when we subtract one temperature from the other.

In this case, the temperature in Harbin was -8ºC and the temperature in Beijing was -2ºC. To find out which city was colder, we need to calculate the temperature difference between the two cities.

To do this, we subtract the temperature in Beijing from the temperature in Harbin:

-8ºC - -2ºC = -6ºC

So the temperature difference between the two cities is -6ºC. This means that Harbin was colder than Beijing on that day.

We can see that the temperature difference is negative, which tells us that the temperature in Harbin was lower than the temperature in Beijing.

The perimeter is the tοtal length οf a shape's bοundary, and the rule fοr finding the οuter perimeter οf Jian's equilateral triangle designs is p = n + 1.

The perimeter οf a twο-dimensiοnal shape is the tοtal length οf its bοundary, which is the sum οf the lengths οf all its sides. It is typically measured in units such as centimeters, inches, οr meters.

Fοr example, the perimeter οf a square with side length s is 4s, since it has fοur sides οf equal length. The perimeter οf a rectangle with length l and width w is 2l + 2w, since it has twο pairs οf sides οf different lengths.

Nοw, let's cοnsider the relatiοnship between the number οf triangles and the οuter perimeter οf Jian's design. Frοm the table, we can see that the οuter perimeter increases by 1 as the number οf triangles increases by 1. Specifically, the οuter perimeter is always 1 mοre than the number οf triangles used in the design.

Therefοre, we can write the rule fοr finding the οuter perimeter p in terms οf the number οf triangles n as:

p = n + 1

This rule tells us that if we knοw the number οf triangles used in a design, we can find the οuter perimeter by adding 1 tο that number.

Answer:So the common factor of the numerator and denominator is (x+7)(x+7) or (x+7)^2, and the simplified expression is (x+1)(x−1).

Step-by-step explanation:

To find the common factor of the numerator and denominator of the expression (x+1)(x+7)(x+7)(x−1), we need to factorize it completely.

(x+1)(x+7)(x+7)(x−1) = (x+1)(x−1)(x+7)(x+7)

Now we can see that the common factor of the numerator and denominator is (x+7)(x+7) or (x+7)^2.

Therefore, we can simplify the expression by dividing both the numerator and denominator by (x+7)^2:

(x+1)(x−1)(x+7)(x+7)/(x+7)(x+7) = (x+1)(x−1)

So the common factor of the numerator and denominator is (x+7)(x+7) or (x+7)^2, and the simplified expression is (x+1)(x−1).

The points F(8,-1), G(2,1), H(1, -2), and I(7,-4) form a quadrilateral. The desired slopes and lengths are follows:

The type of quadrilateral that BEST identifies the given points is a parallelogram.

To find the slopes and lengths of the quadrilateral, we will use the slope formula and the distance formula.

Slope formula: m = (y2 - y1)/(x2 - x1)
Distance formula: d = √((x2 - x1)² + (y2 - y1)²)

Slopes:
FG: m = (1 - (-1))/(2 - 8) = -1/3
GH: m = (-2 - 1)/(1 - 2) = 3
HI: m = (-4 - (-2))/(7 - 1) = -1/3
IF: m = (-1 - (-4))/(8 - 7) = 3

Lengths:
FG: d = √((2 - 8)² + (1 - (-1))²) = √(40) = 2√(10)
GH: d = √((1 - 2)²+ (-2 - 1)²) = √(10)
HI: d = √((7 - 1)^2 + (-4 - (-2))²) = √(40) = 2√(10)
IF: d = √((8 - 7)² + (-1 - (-4))^2) = √(10)

From the above calculations, we can see that the slopes of FG and HI are equal, and the slopes of GH and IF are equal. This means that the opposite sides of the quadrilateral are parallel. Additionally, the lengths of FG and HI are equal, and the lengths of GH and IF are equal. This means that the opposite sides of the quadrilateral are also congruent.

A. To evaluate det(A) by a cofactor expansion along a row or column of your choice, we can choose any row or column and multiply each element by its corresponding minor and sign.

For example, let's choose the first row:

det(A) = (-6)(4*3-0*1) + (0)(2*3-(-1)*2) + (2)(2*0-(-1)*4)

det(A) = (-6)(12) + (0)(6) + (2)(4)

det(A) = (-72) + (0) + (8)

det(A) = -64

Therefore, the determinant of matrix A is -64.

B. Alternatively, we could have chosen any other row or column and the result would have been the same. For example, if we chose the third column:

det(A) = (2)(4*0-2*0) + (-1)(-6*3-2*0) + (3)(-6*0-2*4)

det(A) = (2)(0) + (-1)(-18) + (3)(-8)

det(A) = (0) + (18) + (-24)

det(A) = -6

The solutions to the given equations are x = 10 and m = 1.5.

Using the one-to-one property of logarithms, we can solve the given equations as follows:

First, we will solve the equation: 15.Ln(10−3x)=ln(−4x)
The one-to-one property of logarithms states that if logb(a) = logb(c), then a = c. Therefore, we can use this property to set the arguments of the logarithms equal to each other:

10 - 3x = -4x
Simplifying this equation gives:

10 = x

So the solution to the first equation is x = 10.

Next, we will solve the equation: 16.log4​(6−m)=log4​3(m)
Again, using the one-to-one property of logarithms, we can set the arguments of the logarithms equal to each other:

6 - m = 3m
Simplifying this equation gives:

6 = 4m
m = 6/4
m = 1.5

So the solution to the second equation is m = 1.5.

Therefore, the solutions to the given equations are x = 10 and m = 1.5.

I think 2nd option..........

The speed of the river's current is 3 miles per hour.

To determine the speed of the river's current, we can use the formula d = rt, where d is the distance, r is the rate, and t is the time.

We can set up two equations, one for upstream and one for downstream, and solve for the speed of the river's current.

For upstream:

9 = (6 - c)t

For downstream: 27 = (6 + c)t

Since it takes her the same amount of time to paddle 9 miles upstream as it does to travel 27 miles downstream, we can set the two equations equal to each other:

9 = (6 - c)t = 27 = (6 + c)t

Simplifying and solving for c:

9(6 + c) = 27(6 - c) 54 + 9c = 162 - 27c 36c = 108 c = 3

Louise has 2 1/4 feet more of green yarn than white yarn.

What is the fractions ?

A fraction is a way to represent a part of a whole or a ratio between two quantities.

To compare the amounts of green and white yarn, we need to express the amounts in the same units. Let's convert 2/4 yards of white yarn to feet, since the green yarn is already measured in feet.

1 yard = 3 feet

2/4 yard = 2/4 * 3 feet/yard = 1.5 feet

Now we can compare the amounts of green and white yarn in feet:

Amount of green yarn = 3 3/4 feet

Amount of white yarn = 1.5 feet

To find how many more feet of green yarn Louise has than white yarn, we can subtract the amount of white yarn from the amount of green yarn:

3 3/4 feet - 1.5 feet = 2 1/4 feet

Hence, Louise has 2 1/4 feet more of green yarn than white yarn.

Answer:

20 feet

Step-by-step explanation:

You can use trigonometry to solve this problem. The height of the kite can be found using the sine function. The sine of an angle in a right triangle is equal to the length of the side opposite the angle divided by the length of the hypotenuse.

In this case, the side opposite the 30° angle is the height of the kite (h), and the hypotenuse is the length of the string (40 feet). So we have:

sin(30°) = h / 40

Solving for h, we get:

h = 40 * sin(30°)

Since sin(30°) = 0.5, we have:

h = 40 * 0.5

So, h = 20 feet.

The kite is 20 feet high in the air.

Answer:

To solve this problem, we can use trigonometry. Let's assume that the height of the kite from the ground is h. Then, we can use the tangent function to find the value of h.

We know that the tangent of an angle is equal to the opposite side over the adjacent side. In this case, the opposite side is the height of the kite (h) and the adjacent side is the distance from you to the point directly below the kite on the ground, which is 40 feet.

So we have:

tan(30°) = h/40

Multiplying both sides by 40, we get:

h = 40 tan(30°)

Using a calculator, we can find the value of tangent of 30 degrees, which is approximately 0.5774. So:

h = 40 × 0.5774 ≈ 23.1

Therefore, the height of the kite in the air is approximately 23.1 feet.

ds/dt = sec(t)

To find the length of the curve, we need to find the arc length. The arc length of the curve r(t) is given by:

LENGTH = $\int_{0}^{1} \sqrt{6^{2}\cos^2(t) + 1 + 5^{2}\sin^2(t)} dt$

To find ds/dt, we can take the derivative of the above equation with respect to t:

$\frac{ds}{dt} = \frac{d}{dt} \sqrt{6^{2}\cos^2(t) + 1 + 5^{2}\sin^2(t)}$

$\frac{ds}{dt} = \frac{6^2\cos(t)\sin(t) + 10\sin(t)\cos(t)}{\sqrt{6^{2}\cos^2(t) + 1 + 5^{2}\sin^2(t)}}$

$\frac{ds}{dt} = \frac{16\sin(t)\cos(t)}{\sqrt{6^{2}\cos^2(t) + 1 + 5^{2}\sin^2(t)}}$

$\frac{ds}{dt} = \frac{16\sin(t)\cos(t)}{\sqrt{1+tan^2(t)}}$

(a) The three points are:
(x,y) = ( 2.25 , -3.5 ) (smallest x-value)
(x,y) = ( 2.5 , -4 )
(x,y) = ( 2.75 , -4.5 ) (large x-value)

(x,y) = ( -0.5 , -0.5 )
(x,y) = ( -0.25 , -0.25 ) (large x-value)

To find the three points that divide the line segment joining the given points into four equal parts, we need to use the formula for a point that divides a segment in a given ratio. The formula is:

(x,y) = ( (x1 + rx2)/(1+r) , (y1 + ry2)/(1+r) )

Where (x1,y1) and (x2,y2) are the given points, r is the ratio, and (x,y) is the point that divides the segment in the given ratio.

(a) For the given points (2,-3) and (3,-5), we need to find the points that divide the segment in the ratio 1:3, 2:2, and 3:1.

For the first point, we use the formula with r=1/3:
(x,y) = ( (2 + (1/3)*3)/(1+(1/3)) , (-3 + (1/3)*(-5))/(1+(1/3)) )
(x,y) = ( 2.25 , -3.5 )

For the second point, we use the formula with r=2/2:
(x,y) = ( (2 + (2/2)*3)/(1+(2/2)) , (-3 + (2/2)*(-5))/(1+(2/2)) )
(x,y) = ( 2.5 , -4 )

For the third point, we use the formula with r=3/1:
(x,y) = ( (2 + (3/1)*3)/(1+(3/1)) , (-3 + (3/1)*(-5))/(1+(3/1)) )
(x,y) = ( 2.75 , -4.5 )

So the three points are:
(x,y) = ( 2.25 , -3.5 ) (smallest x-value)
(x,y) = ( 2.5 , -4 )
(x,y) = ( 2.75 , -4.5 ) (large x-value)

(b) For the given points (-1,-1) and (0,0), we need to find the points that divide the segment in the same ratios as before.

For the first point, we use the formula with r=1/3:
(x,y) = ( (-1 + (1/3)*0)/(1+(1/3)) , (-1 + (1/3)*0)/(1+(1/3)) )
(x,y) = ( -0.75 , -0.75 )

For the second point, we use the formula with r=2/2:
(x,y) = ( (-1 + (2/2)*0)/(1+(2/2)) , (-1 + (2/2)*0)/(1+(2/2)) )
(x,y) = ( -0.5 , -0.5 )

For the third point, we use the formula with r=3/1:
(x,y) = ( (-1 + (3/1)*0)/(1+(3/1)) , (-1 + (3/1)*0)/(1+(3/1)) )
(x,y) = ( -0.25 , -0.25 )

So the three points are:
(x,y) = ( -0.75 , -0.75 ) (smallest x-value)
(x,y) = ( -0.5 , -0.5 )
(x,y) = ( -0.25 , -0.25 ) (large x-value)
