Answer:

43.6 has 3 significant figures.

The length of the perpendicular from C to BD is √5

To show that ABCD is a rectangle, we need to demonstrate two things: that the opposite sides of the quadrilateral are parallel and that the diagonals are congruent.

Given the coordinates of the four points:

A(2, 1), B(5, 4), C(4, 5), and D(1, 2).

First, let's find the slopes of the line segments AB, BC, CD, and DA:

Slope of AB = (4 - 1) / (5 - 2) = 3/3 = 1.

Slope of BC = (5 - 4) / (4 - 5) = 1/-1 = -1.

Slope of CD = (2 - 5) / (1 - 4) = -3/-3 = 1.

Slope of DA = (1 - 2) / (2 - 1) = -1.

We can see that opposite sides AB and CD have equal slopes, indicating they are parallel. Similarly, sides BC and DA have equal slopes, also indicating they are parallel.

Next, let's calculate the lengths of the diagonals AC and BD:

Length of AC = \(\sqrt{((4 - 2)^2 + (5 - 1)^2)} = \sqrt{(2^2 + 4}{^2) = \sqrt{(4 + 16)} = \sqrt20\).

Length of BD = \(\sqrt{((5 - 1)^2 + (4 - 2)^2)} = \sqrt{(4^2 + 2^2)} = \sqrt{(16 + 4)} = \sqrt20\).

Since the lengths of the diagonals AC and BD are equal (√20 = √20), the diagonals are congruent.

Therefore, with parallel opposite sides and congruent diagonals, we can conclude that ABCD is a rectangle.

To find the coordinates of the foot of the perpendicular from C to BD, we can calculate the midpoint of BD, which will also be the foot of the perpendicular. The midpoint formula is:

Midpoint = ((x1 + x2)/2, (y1 + y2)/2).

Coordinates of B (5, 4) and D (1, 2):

Midpoint = ((5 + 1)/2, (4 + 2)/2) = (6/2, 6/2) = (3, 3).

Therefore, the foot of the perpendicular from C to BD has coordinates (3, 3).

Lastly, to find the length of the perpendicular from C to BD, we can use the distance formula between points C and the foot of the perpendicular:

Length = \(\sqrt{((4 - 3)^2 + (5 - 3)^2)} = \sqrt(1^2 + 2^2) = \sqrt(1 + 4) = \sqrt5.\)

Thus, the length of the perpendicular from C to BD is √5.

Answer:

122 degrees

Step-by-step explanation:

The two intersecting lines are parallel for this problem, which means that the angle next to angle3 is the same degree measure as the one that is 58 degrees.

Also, remember that two angles next to each other on a straight line are supplementary, meaning that they add to 180 degrees.

When keeping these two things in mind, you can solve like this:

180 = angle3 + 58

180 - 58 = angle3

angle3 = 122

122 degrees

We can see here that the data set approximately periodic. The period and amplitude is: Periodic with a period of 4 and an amplitude of about 30.

The size or magnitude of a wave or vibration is measured by its amplitude in physics. It describes the greatest deviation of a wave from its equilibrium or rest state, or the greatest intensity of an electromagnetic or sound wave.

When referring to waves, amplitude is commonly calculated as the distance between a wave's peak or trough and its resting position.

We can deduce that the values are being repeated at regular interval of four (4).

For the amplitude:

\(Amplitude: \frac{140 - 74}{2}\)

Amplitude = 33 ≈ 30.

Out of the 400 surveyed students, 327 were either seniors or commuters.

To find the number of students who were either seniors or commuters out of the 400 surveyed students, we need to add the number of seniors and the number of commuters while avoiding double-counting those who fall into both categories.

According to the information given:

There were 262 seniors.

There were 215 commuters.

150 of the seniors were also commuters.

To avoid double-counting, we need to subtract the number of seniors who were also commuters from the total count of seniors and commuters.

Seniors or commuters = Total seniors + Total commuters - Seniors who are also commuters

= 262 + 215 - 150

= 327

Therefore, out of the 400 surveyed students, 327 were either seniors or commuters.

It's important to note that in this calculation, we accounted for the overlap between seniors and commuters (150 students who were both seniors and commuters) to avoid counting them twice.

This ensures an accurate count of the students who fall into either category.

Answer:

Approx. 5.5 sq units.

Step-by-step explanation:

Here is how you do it:

To find the area of triangle XYZ, we can use the formula for the area of a triangle given its vertices in the coordinate plane.

Given the vertices of triangle XYZ:

C (-8, 4)

Y (-4, 3)

Z (-5, 6)

To find the area of the triangle, we can use the Shoelace Formula. The formula is as follows:

Area = 1/2 * |(x1y2 + x2y3 + x3y1) - (y1x2 + y2x3 + y3x1)|

Substituting the coordinates into the formula, we get:

Area = 1/2 * |((-83) + (-46) + (-54)) - ((4(-4)) + (3*(-5)) + (6*(-8)))|

= 1/2 * |(-24 - 24 - 20) - (-16 - 15 - 48)|

= 1/2 * |-68 - (-79)|

= 1/2 * |-68 + 79|

= 1/2 * |11|

= 1/2 * 11

= 11/2

Therefore, the area of triangle XYZ is 11/2 square units, which is equal to 5.5 square units

Here is an alternate method:

Call the rectangle as A(-8,6), B(-4,6), C(-4,3), D(-8,3)

THen,

Area of XAZ : 1/2 *3*2 = 3

Area of ZBY : 1/2 *1*3 = 1.5;

Area of XDY : 1/2 * 1 * 4 = 2

Area of rect: 3*4 = 12;

Finally area of the given triangle XYZ = 12-3-1.5-2
                                                              = 5.5 Sq units.

Answer:

  (a) 90°, 90°

  (b) 5, 1

  (c) 10°, 20°

  (d) 10°, 20°, 150°

Step-by-step explanation:

You need to consider ways in which each statement might not apply.

(a) An obtuse angle is greater than 90°. If both angles are 90°, then neither is obtuse.

  counterexample: m∠1 = 90°, m∠2 = 90°

__

(b) If the perimeter is 12, the sum of the side lengths must be 6. There are many ways to get two numbers that have a sum of 6. Here's one:

  counterexample: length = 5, width = 1

__

(c) All that is required is that the sum of angles be 30°. They don't have to be equal.

  counterexample: m∠ABC = 10°, m∠CBD = 20°

__

(d) We know the three angles of a triangle have a sum of 180°, but that does not require it to be an acute triangle. A triangle can also be right or obtuse.

  counterexample: m∠P = 10°, m∠Q = 20°, m∠R = 150°

Answer:

\(\frac{9344}{45}\)

Step-by-step explanation:

\(\frac{74752}{360}\)

Simplify by 8, and we get

\(\frac{9344}{45}\)

We can't simplify any more, so the answer is  \(\frac{9344}{45}\)

The required answer is the simplified fraction of the given problem 74752/360 is the whole fraction 9344/45, where 9344 represents the whole number part and 45 represents the fractional part.

To simplify the fraction 74752/360 as a whole fraction, we need to find the greatest common divisor (GCD) of the numerator and the denominator and divide both of them by it.

Step 1: Find the GCD of 74752 and 360. The GCD can be calculated using various methods, such as prime factorization or the Euclidean algorithm. In this case,  use the Euclidean algorithm.

Let's find the GCD using the Euclidean algorithm:

Divide 74752 by 360:

74752 ÷ 360 = 207 R 272

Divide 360 by 272:

360 ÷ 272 = 1 R 88

Divide 272 by 88:

272 ÷ 88 = 3 R 8

Divide 88 by 8:

88 ÷ 8 = 11 R 0

Since the remainder is 0, the GCD is the last non-zero remainder, which is 8.

Step 2: Divide both the numerator and denominator of the fraction by the GCD.

74752 ÷ 8 = 9344

360 ÷ 8 = 45

The simplified whole fraction is 9344/45.

A whole fraction refers to a fraction in which the numerator is equal to or greater than the denominator. It represents a whole number and a fraction together. For example, 3 1/4 is a whole fraction where the whole number part is 3 and the fractional part is 1/4.

Hence, the simplified fraction of the given problem 74752/360 is the whole fraction 9344/45, where 9344 represents the whole number part and 45 represents the fractional part.
