What is the diameter of triangle?

In a triangle, the diameter is a line segment that passes through the midpoint of one side of the triangle and is perpendicular to that side. It is also the longest chord of the triangle. The length of the diameter is called the diameter of the triangle.

Draw the diameter from point (-1, -5) to point (2, 3).

The triangle has base 3 and height 8.

The diameter of the semicircle is the hypotenuse of the triangle.

d = root(3² + 8²)

d = 8.544

The radius is half the diameter.

r = d/2 = 8.544/2 = 4.272

The total area is the area of the triangle plus the area of the semicircle.

A = 3*8/2 + π*4.272²/2

The measure of angle K and L in the first figure is ∠L = 23 degrees and ∠K = 157. Second figure, the measure of ∠K = ∠L = 70 degrees.

A polygon's interior angle is the angle created between its two adjacent sides. Alternately, we may state that the internal angle of a polygon refers to the angle measured at the interior portion of a polygon.

For figure 2 the two lines are parallel to each other, and the line that meets the parallel line at points at M and L are from two equal lines.

Hence, the angle suspended by both are equal, that is:

∠L = ∠M

∠L = 23 degrees.

Now, the ∠K and ∠J are created by two parallel lines; hence they are equal:

∠K = ∠J = x

The sum of interior angles of a quadrilateral is 360, so:

∠L + ∠M + ∠J + ∠K = 360

23 + 23 + x + x = 360

46 + 2x = 360

2x = 360 - 46

x = 157

Hence, the measure of angle K and L is 157 and 23 respectively.

For the second figure, the angle K and L are created by equal length of segments.

∠K = ∠L = x

The sum of interior angles of a quadrilateral is 360, so:

∠L + ∠M + ∠J + ∠K = 360

x + 90 + 130 + x = 360

2x + 220 = 360

2x= 360 - 220

x = 70

Hence, the angle of K and L is 70 degrees.

The exact length (in inches) of the arc of a circle formed by given angle (in radians) and radius  is 5.233 inches.

The radius of a circle and the central angle determine the length of an arc. We are aware that given an angle of 360 degrees, the arc length corresponds to the circumference. Thus, the arc length is determined by multiplying the radius by the Centre angle (in radians).

Arc length = radius x angle(in radians)

Radius = 2 inches

Angle = 5pi/6 radians

Arc length = 2 x (5pi/6)

                = 5.233

Hence, the arc length is 5.233 inches.

The row in Pascal's triangle where three consecutive entries are in the ratio 3:4:5 is the 62nd row.

To find the row in Pascal's triangle where three consecutive entries are in the ratio 3:4:5, we will use the concept of binomial coefficients.

The binomial coefficient C(n, k) represents the number of ways to choose k items from a set of n items, and is given by the formula -

C(n, k) = n! / (k! (n-k)!).

In Pascal's triangle, the entries are arranged such that the nth row contains n+1 entries, and the kth entry in that row is given by C(n, k).

We can determine the ratio of three consecutive entries in Pascal's triangle by looking at the binomial coefficients C(n, k), C(n, k+1), and C(n, k+2) in a particular row.

In order to find the row where the ratio of these three consecutive entries is 3:4:5, we will set up the following equation:

C(n, k) / C(n, k+1) = 3/4 and C(n, k+1) / C(n, k+2) = 4/5

We will now use the formula for binomial coefficients to simplify these equations as follows -

(n! / (k! (n-k)!) ) / (n! / ((k+1)! (n-(k+1))!)) = 3/4

Similarly,

(n! / ((k+1)! (n-(k+1))!)) / (n! / ((k+2)! (n-(k+2))!)) = 4/5

Solving for n, we can get n = 62

Therefore, the row in Pascal's triangle where three consecutive entries are in the ratio 3:4:5 is the 62nd row.

The dimension of the largest possible rectangular area that can be fenced for $4800 is 300 yard × 150 yard. The area, A of the rectangle as a function of its width, w is A = 300w - 1.5w².

Let the width of the rectangular area be "w" and its length be "l".

The cost of the east-west direction fencing is

2w * 12 = 24w

and the cost of the north-south direction fencing is

2l * 8 = 16l

Since the rancher wants to spend exactly $4800 on fencing, we can write an equation to represent the cost:

24w + 16l = 4800

Divide by 8

3w + 2l = 600

Therefore, l = 300 - 1.5w

The area of the rectangle is given by "lw", so

A = lw

Substituting the value of "l" from the first equation into this second equation:

A = (300 - 1.5w)w

A = 300w - 1.5w²

Thus, the area of the rectangle is a function of its width and can be expressed as Area = 300w - 1.5w².

To find value of w with maximum area, dA/ dw = 0

300 - 3w = 0

w = 100

Therefore, l = 300 - 1.5*100

l = 150

Answer:

No, these ratios are not equivalent.

Step-by-step explanation:

The initial velocity is related to the maximum height by the relation [tex]v_{0}=\sqrt{\frac{2gH}{3} }[/tex]

The initial velocity (v0) is the velocity of an object at the beginning of its motion. In the scenario you described, the initial velocity of the rock is the velocity at which it is thrown upward from the edge of the roof of a building.

Without any information about the velocity at which the rock is thrown, it is not possible to determine the initial velocity.

Using the fact that the velocity at maximum height is zero, we can write the following:

      [tex]v_{y}=v_{y_{0,t} }+ a_{y}t[/tex]

at maximum height, the equation becomes

[tex]0=v_{0}-gT_{max}[/tex]

=> [tex]T_{max}=\frac{v_{0} }{g}[/tex]

Now, the displacement is (-H)−H) when the rock hits the ground, so we can use one of the kinematic equations to write the following

[tex]y-y_{0}=v_{0}t+\frac{1}{2}a_{y}t^{2}[/tex]

where [tex]y_{0} =0 and y=-H[/tex]

On substituting the values and rearranging we get:

[tex]v_{0}=\sqrt{\frac{2gH}{3} }[/tex]

Therefore, The initial velocity is related to the maximum height by the relation [tex]v_{0}=\sqrt{\frac{2gH}{3} }[/tex].

When converting fractions to decimal probabilities, it is important to include the percentage sign (%) at the end. This is because when converting a fraction to a decimal, the result is not a whole number, but a decimal probability. For example, 1/6 can be written as a decimal probability of 0.17, but it is usually written as 0.17% to indicate the probability of an event occurring. The percentage sign is essential for students to understand that the decimal is a probability, rather than an incorrect answer. Percentage sign also allows the decimal to be rounded to two decimal places, giving a more precise answer.

The answer to this question is determined on the volume of water coming from the faucet. When the tap is switched on but no water flows out, the tank can retain 275 gallons eternally. Yet, if water flows out of the tap at a constant pace, the tank will take a given period of time to empty.

A gallon is a volume unit used mostly in the United States, equivalent to 128 US fluid ounces or 3.785 liters.

To establish how long it will take to empty the tank, we must first know the flow rate of the tap, which is normally measured in gallons per minute (GPM). We may use the following calculation to calculate the time it will take to empty the tank once we have known the GPM:

Time (minutes) = 275 gallons per minute / GPM

For example, if the tap is running at a rate of 10 GPM, the time required to empty the tank is:

Time (minutes) = 275 gallons /10 GPM = 27.5 minutes

As a result, if the tap is set at 10 GPM, it will take 27.5 minutes for the tank to empty before Angel can turn off the water.
