according to the question the distance between the points (1, 5) and (3, 8) is √13 units.

Distance is an object's total, aimless movement. Without regard to whether an object represents a starting or finishing point, distance can be defined as the total distance travelled. Distance is referred to as the breadth or height of the difference between two locations. It should be highlighted that the distance between each of the vantage points as well as the distance travelled from one to the other are not the same thing. The total length of a path connecting two locations counts as the distance travelled. Distance is the real distance that a body travels. It also goes by the name "path length." For instance, the length of the route for an object moving from point O to point P would be OP = 360 m.

given,

To find the distance between the points (1, 5) and (3, 8), we can use the distance formula:

distance = √[(x2 - x1)² + (y2 - y1)²]

Substituting the given values, we get:

distance = √[(3 - 1)² + (8 - 5)²]

distance = √[4 + 9]

25 - 20 = 5

19 - 15 = 4

26 - 19 = 7

The find the average of the set of scores

24.4 , 19.8, 1.52

Hypothesis formulation

H0: µ1 = µ2

Ha: µ1 ≤ µ2

Decide the test statistic and the level of significance:

alpha = 0.05

df = 5 - 1 = 4

The upper critical value at the level of significance = 2.7764

And the lower critical value at the level of significance = -2.7764

The decision rule

Reject H0 if |t| > 2.7764

The line of symmetry of the parabola is t = 1.875 and the vertex of the parabola is (1.875, 77).

A function is a mathematical concept that relates an input value (or values) to an output value (or values) according to a specific rule or set of rules. It can be thought of as a machine that takes in one or more inputs and produces a corresponding output. Functions are often represented using function notation, such as f(x) or g(t), where the variable in the parentheses (x or t) represents the input and the value of the function (f(x) or g(t)) represents the output.

To identify the line of symmetry and vertex of the parabola given by the function [tex]f(t) = -16t^2 + 60t + 16[/tex], we need to use the formula:

t = -b/2a

where "a" is the coefficient of the [tex]t^2[/tex] term (-16 in this case) and "b" is the coefficient of the t term (60 in this case).

Part A: Identify the line of symmetry of the parabola.

Using the formula above, we get:

t = -60 / 2(-16) = 1.875

So the line of symmetry of the parabola is t = 1.875.

Part B: Identify the vertex of the parabola.

To find the vertex, we need to substitute the value we found for t into the original function:

[tex]f(1.875) = -16(1.875)^2 + 60(1.875) + 16 = 77[/tex]

So the vertex of the parabola is (1.875, 77).

Therefore, the line of symmetry of the parabola is t = 1.875 and the vertex of the parabola is (1.875, 77).

The guests in the birthday party ate 33 cookies.

We know that Mrs. Smith made 6 1/4 dozen cookies and there were 3 1/2 dozen cookies left.

Let's first convert these fractions to a common denominator of 4, so we can easily subtract them.

6 1/4 dozen = 25/4 dozen

3 1/2 dozen = 14/4 dozen

Now we can subtract the number of cookies that were left from the number of cookies that were made:

25/4 - 14/4 = 11/4 dozen

To find out how many cookies this represents, we need to multiply by the number of cookies in one dozen.

To find the perimeter of the polygon with vertices at   [tex](1, 2), (4, 6),[/tex] and  [tex](7, 2),[/tex] we need to find the length of each side of the polygon and add them up.

Using the distance formula, we can find the length of each side:

The length of the side connecting (1, 2) and (4, 6) is:

[tex]\sqrt((4-1)^2 + (6-2)^2) = \sqrt(3^2 + 4^2) = 5[/tex]

The length of the side connecting [tex](4, 6) and (7, 2) is:\sqrt((7-4)^2 + (2-6)^2) = \sqrt(3^2 + (-4)^2) = 5[/tex]

The length of the side connecting [tex](7, 2) and (1, 2) \ is:\ \sqrt((1-7)^2 + (2-2)^2) = \sqrt((-6)^2 + 0^2) = 6[/tex]

The proof that f(2x)=3f(x)+1/f(x)+3 is shown below.

To show that f(2x) = 3f(x) + 1/f(x) + 3, we substitute 2x for x in the expression for f(x):

f(x) = x - 1 / x + 1

f(2x) = 2x - 1 / 2x + 1

Next, we substitute x into the expression for f(x) and add the result to itself twice:

f(x) = x - 1 / x + 1

f(x) + f(x) + f(x) = (x - 1 / x + 1) + (x - 1 / x + 1) + (x - 1 / x + 1)

= 3x - 3 / 3x + 3

We can simplify the expression by dividing both the numerator and denominator by 3:

f(x) + f(x) + f(x) = x - 1 / x + 1

= (1/3) (3x - 3) / (1/3) (3x + 3)

= (x - 1) / (x + 1)

= f(x)

Now, we substitute f(x) and f(2x) back into the original equation:

f(2x) = 2x - 1 / 2x + 1

3f(x) + 1/f(x) + 3 = 3(x - 1 / x + 1) + 1/(x - 1 / x + 1) + 3

= (3x - 3 / x + 1) + (1 / (x - 1 / x + 1)) + 3

= (3x - 3 + (x + 1) / (x - 1)) / (x + 1)

= (2x + 2) / (x + 1)

= 2(x + 1) / (x + 1)

= 2

Thus, we have shown that f(2x) = 3f(x) + 1/f(x) + 3.

Answer:

 a.  1492 kg

  b.  20.8 m

Step-by-step explanation:

Given a tree is initially 20 m high and has a diameter of 0.5 m, you want the mass of the trunk if its density is 380 kg/m³. If it adds a growth ring of 4 mm per year and adds height of 0.2 m in the first year, you want the height of the tree after 5 years, assuming the same amount of wood is added each year.

The volume of the tree trunk is that of a cylinder. The formula is ...

  V = (π/4)d²h

  V = (π/4)(0.5 m)²(20 m) ≈ 3.9270 m³

The mass is the product of volume and density:

  M = Vρ

  M = (3.9270 m³)(380 kg/m³) ≈ 1492 kg

The mass of the tree trunk is about 1492 kg.

In the first year, the diameter of the tree increases by 8 mm, and the height increases by 0.2 m,. This means the volume of the tree increases to ...

  V = (π/4)(0.508 m)²(20.2 m) ≈ 4.0942 m³

The volume increase is the same each year for 5 years, so after 5 years, the volume is ...

  3.9270 m³ + 5(4.0942 -3.9270) m³ ≈ 4.7630 m³

At that time, the diameter is about 0.540 m. Solving the volume equation for the height, we find it to be ...

  h = 4v/(π·d²)

  h = 4(4.7630 m³)/(π·(0.54 m)²) ≈ 20.797 m

The height of the trunk after 5 years is about 20.8 m.

__

Additional comment

We note that the wood added in the first year includes the cylindrical shell represented by the tree ring, and a cylindrical "plug" that is 0.2 m high and equivalent in diameter to the rest of the tree. This seems an odd way for the tree to grow, but may be a reasonable approximation to the actual growth.

The height, diameter, and growth are all given to 1 significant figure. Hence the 4- and 3-significant figures used in the answers may be unsupported by the precision of the given numbers. Keeping 2 significant figures, we might report the initial mass as 1500 kg, and the final height as 21 m.

The graph is drawn by a function formulated to have the correct height at the x-intercept: v(d, h) - (final volume) = 0.

<95141404393>

We can use the formula for the volume of a cylinder: V = Ah, where A is the base area and h is the height.

Substituting the given values, we have:

720 cm³ = 36 cm² x h

Simplifying, we can divide both sides by 36 cm²:

20 cm = h

Therefore, the height is 20 cm.

The total number of 6 tickets will be earned when 54 points are earned.

Given that the total number of tickets earned for 9 points was earned = 1 ticket

the tickets earned when every 18 points are earned = 2 tickets

the tickets earned when every 27 points are earned = 3 tickets

Let's divide the points by tickets to find out how many points are earned for each ticket.

9/1 = 18/2 = 27/3 = 9

This shows for every ticket 9 points are earned. So, to find out the no. of tickets for 54 points, we can divide the 54 by 9.

no. of tickets earned for 54 points = 54/9 = 6 tickets.

From the above analysis, we can conclude that the 6 tickets are earned for 54 points.

To find the lower and upper quartiles and the interquartile range, we first need to order the data from smallest to largest:

20, 22, 25, 28, 29, 30, 32, 33, 34

Next, we find the median (middle value) of the entire dataset:

Median = (29 + 30) / 2 = 29.5

This median value divides the data into two halves. We then find the median of the lower half of the data, which includes all values less than or equal to 29.5:

Lower half: 20, 22, 25, 28, 29

Median of lower half = (25 + 28) / 2 = 26.5

This value, 26.5, is the lower quartile (Q1).

Similarly, we find the median of the upper half of the data, which includes all values greater than or equal to 29.5:

Upper half: 30, 32, 33, 34

Median of upper half = (32 + 33) / 2 = 32.5

This value, 32.5, is the upper quartile (Q3).

Finally, we can calculate the interquartile range (IQR) as the difference between the upper and lower quartiles:

IQR = Q3 - Q1 = 32.5 - 26.5 = 6

Therefore, the lower quartile is 26.5, the upper quartile is 32.5, and the interquartile range is 6.
