Let θ = 855∘. Complete parts (a), (b), and (c) below. (a) Sketch θ in standard position. (b) Find an angle between 0∘ and 360∘ that is coterminal with θ. (c) Find an angle between −360∘ and 0∘ that is coterminal with θ
Let θ be equal to 855∘. Sketch θ in standard position. θ = 855∘ is in the fourth quadrant of the coordinate plane θ = 855∘
The given angle, θ, is a positive angle. It is measured in the counterclockwise direction from the initial side to the terminal side.Hence, we sketch θ in the standard position with its initial side along the positive x-axis.
Find an angle between 0∘ and 360∘ that is coterminal with θ.
The angle between 0∘ and 360∘ that is coterminal with θ is given by:
θ1 = θ - n × 360∘θ1 = 855∘ - 2 × 360∘θ1 = 855∘ - 720∘θ1 = 135∘
Therefore, an angle between 0∘ and 360∘ that is coterminal with θ is 135∘.Find an angle between −360∘ and 0∘ that is coterminal with θ.
The angle between −360∘ and 0∘ that is coterminal with θ is given by:
θ2 = θ + n × 360∘θ2 = 855∘ + 2 × 360∘θ2 = 855∘ + 720∘θ2 = 1575∘
Therefore, an angle between −360∘ and 0∘ that is coterminal with θ is 1575∘.To learn more about “angle” refer to the https://brainly.com/question/25716982

The _____ in which ratio is expressed is important
In mathematics, a ratio is a comparison of two quantities or numbers expressed in terms of division. The order in which the quantities are expressed in a ratio is also important.
Ratios are used in various mathematical applications such as in finance, geometry, and physics. The units or quantities being compared in a ratio are crucial in determining the meaning and significance of the ratio.
For example, if the ratio is expressed as 2:1, it could mean that the first quantity is twice the size of the second quantity, or it could mean that the second quantity is half the size of the first quantity. Therefore, it is important to clearly define the units or quantities being compared to avoid any ambiguity or misunderstanding.
In the example above, if the ratio was expressed as 1:2 instead of 2:1, the meaning of the ratio would be reversed. Therefore, the order of the quantities in a ratio should be consistent with the context in which it is being used. In summary, the units and the order in which the quantities are expressed in a ratio are important in conveying accurate and meaningful information.

Find the solution(s) to the system, if it exists. State the solution as a point (be sure to use parentheses), use parameter(s) s and t if needed. If the system is inconsistent, then state no solution.
The system has infinitely many solutions, which can be written as (x, y, z) = (1 - 60s, -10 + 600s, s) where s is a parameter.
To solve the system of equations:
1x + 0y + 60z = 1
1x + 10y + 0z = 0
0x + 0y + 0z = 0
The third equation is an identity, implying that it does not give us any new information. The first two equations can be used to solve for x, y, and z:
From the first equation, we get x = 1 - 60z
From the second equation, we get y = 0 - 10x = -10(1 - 60z) = -10 + 600z
Therefore, the solution to the system can be written as a point in terms of z as:
(x, y, z) = (1 - 60z, -10 + 600z, z)
Since z can take on any value, there are infinitely many solutions to the system, which can be parameterized as:
(x, y, z) = (1 - 60s, -10 + 600s, s) where s is a parameter.

The bank statement that is shown in the question shows a loss of £285.00 and calculated by subtracting the total expenses (money out) from the total revenue (money in).
Define profit or loss?Profit or loss is a measure of the financial performance of a business, organization, or individual over a given period of time.
Profit refers to the positive difference between the revenue earned by a business or individual and the expenses incurred during a given period.
A loss occurs when the expenses incurred exceed the revenue earned during a given period.
To calculate the profit or loss, you need to subtract the total expenses (money out) from the total revenue (money in).
In this case, the total revenue is £315.00 + £265.00 + £190.00 = £770.00, and the total expenses are £210.00 + £30.00 + £450.00 + £100.00 = £790.00.

The observer deck of a ship is located at the origin of a coordinate system. Find the bearing of an object located at the point (5, 5).
Answer:
The observer deck of a ship is located at the origin of a coordinate system. Find the bearing of an object located at the point (5, 5).
Step-by-step explanation:
To find the bearing of an object located at the point (5, 5) relative to the observer deck at the origin of a coordinate system, we need to find the angle between the positive x-axis and the line connecting the observer deck to the object.
First, we calculate the slope of the line connecting the observer deck at (0, 0) to the object at (5, 5):
slope = (change in y) / (change in x)
= (5 - 0) / (5 - 0)
= 1
Next, we use the inverse tangent function to find the angle whose tangent is equal to the slope:
angle = arctan(slope)
= arctan(1)
= 45°
Therefore, the bearing of the object located at (5, 5) relative to the observer deck at the origin is 45 degrees.
Answer:
45° north of east
Step-by-step explanation:
tan⁻¹(y/x) = tan⁻¹(5/5) = tan⁻¹(1) = 45°

From midnight to 8:00 am, the temperature rose 1. 51. 5°C each hour. If the temperature at midnight was -3−3°C, what was the temperature at 8:00 am?
the temperature at 8:00 am is 9°C This means that every hour from midnight to 8:00 am, the temperature increased by 1.5°C, resulting in a total increase of 12°C over the 8 hour period.
To solve this problem, we need to use the formula for calculating the final temperature based on the initial temperature and the rate of change per hour.
The formula for this is:
Final Temperature = Initial Temperature + (Rate of Change per Hour x Number of Hours)
In this case, the initial temperature is -3°C, the rate of change per hour is 1.5°C, and the number of hours is 8.
Plugging these values into the formula, we get:
Final Temperature = -3 + (1.5 x 8)
Final Temperature = -3 + 12
Final Temperature = 9°C
Therefore, the temperature at 8:00 am is 9°C.
This means that every hour from midnight to 8:00 am, the temperature increased by 1.5°C, resulting in a total increase of 12°C over the 8 hour period.
It's important to note that this problem assumes that the rate of change per hour remains constant throughout the 8 hour period. In reality, the temperature may fluctuate based on various factors, such as wind, cloud cover, and humidity. However, for the purposes of this problem, we can assume that the rate of change per hour remains constant.

To find out the equation of the line , we need to find out the slope first. It can be calculated as ,
[tex]\implies m =\dfrac{\Delta y}{\Delta x }=\dfrac{y_2-y_1}{x_2-x_1} \\[/tex]
And here ,
[tex] y_1[/tex] = 20[tex]y_2[/tex] = 25[tex]x_1 [/tex] = 3[tex]x_2 [/tex] = 8On substituting the respective values, we have;
[tex]\implies m =\dfrac{25-20}{8-3} \\[/tex]
[tex]\implies m=\dfrac{5}{5}\\[/tex]
[tex]\implies m=\boxed{1} \\[/tex]
Hence the slope of the line is 1 . Now we may use point slope form of the line to find out the equation of the line. Point slope form of the line is,
[tex]\implies y - y_1 = m(x-x_1) \\[/tex]
Take any of the given two points. Here i am taking (3,20) . So here we have;

Luis can drive 4 times fast as Rico can ride his bicycle. If it takes Rico 3 hours longer than Luis to travel 24 miles, how fast can Rico ride his bike
The Rico ride his bike at a speed of 6 miles per hour.
Define the term speed?Speed is a measure of how quickly an object moves, calculated as the distance traveled per unit of time.
Let's take Rico's speed on his bicycle is 'r'.
So, Luis's speed can be expressed as 4r.
Time = Distance / Speed
For Luis, the time it takes to travel 24 miles is:
Time = 24miles / 4r
For Rico, the time it takes to travel 24miles is:
Time = 24miles / r
Since Rico takes 3 hours longer than Luis to travel the same distance (24miles), we can set up an equation:
24miles / r = (24miles / 4r) + 3hour
Simplifying this equation, we get:
⇒ 24 = 6 + 3r
⇒ r = 6
Therefore, Rico can ride his bike at a speed of 6 miles per hour.

2. This is because the circumference and area of a circle are directly proportional to the radius.
3. To determine if triangles ABC and DEF are similar, we need to check if their corresponding angles are congruent and if their corresponding sides are in proportion. From the diagram, we can see that angle A is congruent to angle D, angle B is congruent to angle E, and angle C is congruent to angle F. This satisfies the angle-angle (AA) similarity criterion. Additionally, we can use the side-side-side (SSS) similarity criterion to determine if the corresponding sides are in proportion. From the diagram, we can see that side AB is parallel to side DE, side AC is parallel to side DF, and side BC is parallel to side EF. Therefore, we can conclude that triangles ABC and DEF are similar.

Percentage:
In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. If we need to calculate the percentage of a number, we divide the number by the whole number and multiply by 100. So , percent means one hundredth and the word percent means every 100th. It is represented by the symbol "%".
Calculate the percentage of a total value:
Since percent implies 100, we will split the total portion into 100 parts and then multiply it by b to gather b things per 100 items.
The percentage increase is found as:
[tex]% increase = \frac{change in value}{original value}[/tex][tex]%increase = \frac{change in value}{original value}[/tex][tex]%[/tex]% increase = Change in value/ Original value
⇒ % increase = [tex]\frac{13-25}{25} * 100[/tex]
⇒ % increase = 72
Hence, the percent increase rounded to the nearest hundredth will be 72.
