Circumference = 2π

Step-by-step explanation:

The formula for a circle's circumference is:

C = 2πr

Here is a quick breakdown:

C = circumference

r = radius

Since we are given that the radius is 1 mile, we can plug in r into the formula above:

The provided rectangular box's surface area as a function of the base's side length is S(a) = a² + 8/a.

A solid object's surface area is a measurement of the overall space that the object's surface takes up.

In comparison to the definition of arc length for one-dimensional curves or the definition of surface area for polyhedra (i.e., objects with flat polygonal faces), where the surface area is the sum of the areas of its faces, the mathematical definition of surface area in the presence of curved surfaces is significantly more complex:

Let a be the base's side length and h be the box's height. We are aware that the formula: can be used to calculate the volume of a rectangular box.

V = length * Width * Height

Since the base of this particular box is square,

l = a

w = a

h = h

Now, if we plug these values into the volume formula, we'll get:

2 = a*a*a

2  =a²h

h = 2/a²

Since the surface area up until this point will depend on only two variables, the objective was to minimize the number of variables.

We had to calculate h in terms of a because we wanted to make it a function of a.

We may now apply these to the box's surface area.

Given that this is an open rectangular box, one of the bases in the formula must be removed.

[tex]\begin{aligned}S & =2(b h+h l)+l b \\S & =2(a h+h(a))+a(a) \\S & =2(2 a h)+a^2 \\S & =a^2+4 a h \\S(a) & =a^2+4 a\left(\frac{2}{a^2}\right) \\S(a) & =a^2+\frac{8}{a}\end{aligned}[/tex]

Therefore, the provided rectangular box's surface area as a function of the base's side length is S(a) = a² + 8/a.

To earn back the amount Helen spent on certification, she would need to earn $90. Since her base salary is $55 per month, she would need to teach an additional $90 - $55 = $35 in classes. Since she earns $5 per class, she would need to teach $35 / $5 = 7 classes.

So, Helen will need to teach 7 classes to earn back the amount she spent on certification.

Her total earning for teaching 7 classes would be $55 (base salary) + $5 (per class) * 7 (classes) = $110

Therefore Helen's expenses and earning would be $90 (certification cost) and $110 (earning) respectively.

Using the information given, select the statement that can deduce the line segments to be parallel. If there are none, then select none.

When m8 = m4, the line segments are parallel.

When two line segments have the same slope (m8 = m4), then the line segments are parallel. Therefore, the statement that the line segments are parallel can be deduced if m8 and m4 are equal.

When two line segments have the same slope, then they will be parallel to each other. This can be deduced when the slopes of both line segments are equal, which is represented by m8 = m4. If the two line segments have the same slope, then they will be parallel to each other and will never meet or intersect. This is because parallel lines always have the same slope and never touch each other. In conclusion, the statement that two line segments are parallel can be deduced if m8 and m4 are equal.

Answer: 2/3

Step-by-step explanation: you are looking for the constant of proportionality. We find this with the following formula: K = Y/X

Student A has visited Website B: w(A,B).

This statement can be expressed in English as: "Student A has visited Website B." The formula for this statement is w(x, y), where x is the student, and y is the website. To calculate this statement, we would substitute A for x, and B for y, resulting in w(A, B). This tells us that Student A has visited Website B., we can use the formula w(x,y) = x * y, where x is the total number of students in the school and y is the total number of websites. For instance, if there are 100 students and 10 websites, then the total number of visits would be 100 * 10, or 1000 visits.

The statement "Student A has visited Website B" can be expressed in the formula w(x, y), where x is the student, and y is the website. To calculate this statement, we would substitute A for x, and B for y, resulting in w(A, B), which tells us that Student A has visited Website B.

The graph of the ordered pairs is plotted using the x- coordinates and the y-coordinates. As the straight line does not pass through all the points the relationship is not a linear function.

One variable is directly proportionate to the other in a linear connection, which is a sort of connection between two variables. To put it another way, one variable rises or falls linearly as the other one rises or falls, correspondingly. A line graph, in which the rate of progression is constant, is a frequent graphic depiction of a linear connection. Numerous branches of research, such as physics, psychology, and economics, utilize linear correlations.

The graph of the ordered pairs is plotted using the x- coordinates and the y-coordinates.

When the points are connected using a straight line, the line does not pass through the last point (4, 4). Thus, the ordered pairs do not represent a linear function. This can be determined using the graph, and the points through with the straight line passes.

Answer:

Step-by-step explanation:

-7y=-34+29

-7y=-5

y=-5/-7

y=5/7

Answer:

y = 9

Step-by-step explanation:

-x -7y = -34

if x = -29:

-(-29) -7y = -34

+29 - 7y = -34

-7y = -34 - 29

-7y = -63

y = -63/-7

y = 9

Check:

-(-29) - (7*9) = -34

29 - 63 = -34

Answer:



Step-by-step explanation:

sin 300° = sin (300° - 360°) = sin (-60°) = -sin 60° = -(1/2)

cos 945° = cos (945° - 360°) = cos (585°) = cos (-295°) = -cos 295°

tan (-675°) = -tan (675° - 360°) = -tan 315°

so

sin 300° − cos 945° + tan(−675°) = -(1/2) - (-cos 295°) + (-tan 315°)

It is not a trivial task to simplify the above equations without using a calculator.



= -(1/2) + cos 295° + tan 315°

As we know that cos(x) = cos(360°-x) = -cos(x) and tan(x) = -tan(360°-x) = -tan(x)

= -(1/2) - cos 295° - tan 315°

As we know that cos(295°) = cos(360°-65°) = cos(65°) and tan(315°) = tan(360°-45°) = tan(45°)

= -(1/2) - cos(65°) - tan(45°)

= -(1/2) - 0.4226 - 1

= -0.5 - 0.4226 - 1

= -1.4226

The slope-intercept form of the equation is y = (-5/3)x + 19

Her set-up time decrease by 5/3 hours/day

The equation of a line is an algebraic form of representing the set of points, which together form a line in a coordinate system

(a) The slope-intercept form of  the equation of a line is y = mx+b,

where m is the slope (rate) and b is the y-intercept (starting point)

Let y be the set up time (hours) and x be the time (days)

m = (y₂-y₁)/(x₂-x₁)

where (x, y) are the coordinate of points on the line

From the graph: x₁ =3, y₁ = 14 and x₂ = 6, y₂ = 9

m = (9-14)/(6-3) = -5/3

y = mx + c

14 = (-5/3)×3 + c

14 = -5 + c

c = 14 + 5

c = 19

Thus, the equation is y = (-5/3)x + 19

(b) At day 0, x = 0:

y = (-5/3)x + 19

y = (-5/3)(0) + 19

y = 19 hours

n = 400: 0.9984

b. The advantage of a larger sample size when attempting to estimate the population mean is that it increases the precision and accuracy of the estimate. As the sample size increases, the sample mean becomes a more reliable estimate of the population mean, and the standard error of the mean decreases.
