Trigonometry:The study of correlations between triangles' side lengths and angles is known as trigonometry. The field was created in the Hellenistic era in the third century BC as a result of the use of geometry in astronomical research.Trigonometry is the branch of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (cosec).Given -
[tex]sin(x)=0\\cos(x)=1[/tex]
So [tex]cot(x)=-[/tex].
Therefore, [tex]cot(x)[/tex] is undefined.

y + 2 = negative 2 (x minus 5)
What is the equation in slope-intercept form?
Answer:
[tex]y = -2x + 8[/tex]
Step-by-step explanation:
Step 1: Solve
[tex]y + 2 = -2(x - 5)[/tex]
[tex]y + 2 - 2 = -2x + 10 - 2[/tex]
[tex]y = -2x + 8[/tex]
Answer: [tex]y = -2x + 8[/tex]
Answer:
y= -2x + 12
Step-by-step explanation:
y +2 = -2 ( x - 5 )
y+2 = -2x + 10
-2 -2
y= -2x + 12
y=7x + 10
y=-4x – 23
Answer:
x = -3
y = -11
Step-by-step explanation:
to solve this linear equation using substitution method
let us say that
y=7x + 10.........................................................equation 1
y= -4x – 23...................................................... equation2
substitute equation 1 into equation 2
7x + 10 = -4x - 23
collect the like terms
7x + 4x = -23 -10
11x = -33
divide both sides by the coefficient of x which is 11
11x/11 = -33/11
x = -3
put the value of x = -3 into equation 2
y= -4x – 23...................................................... equation2
y = -4(-3) - 23
y = 12 - 23
y = -11
therefore the value of x and y is -3 and -11 respectively
Solution is x=-3 , y=-11.
We set the ys equal.
[tex]7x+10=-4x-23\\7x+4x=-23-10\\11x=-33\\x=-3[/tex]
For x=-3,
[tex]y=7x+10\\y=7(-3)+10\\y=-21+10\\y=-11[/tex]

is the area of its base? (Round to the nearest tenth)
Answer:
1) The height of the prism is 8 units.
2) The area of its base is 27 square cm.
Step-by-step explanation:
The formula of a rectangular prism is
[tex]\text{Volume}=\text{Area of base}\times \text{Height}[/tex]
1) Given : The area of the base of a rectangular prism is 225 units square If the volume is 1800 cubic units.

-12m-8m+5=-25m-20 solve equation
Answer:
m=-5
Step-by-step explanation:
Given: -12m-8m+5=-25m-20
Combine like terms on left side: -20m+5=-25m-20
Add 25m to both sides: 5m+5=-20
Subtract 5 on both sides: 5m=-25
Divide both sides by 5: m=-5
So m=-5
Answer:
m = -5
Step-by-step explanation:
-12m-8m+5=-25m-20
Combine like terms
-20m +5 = -25m -20
Add 25m to each side
-20m+25m+5=-25m+25m-20
5m +5 = -20
Subtract 5 from each side
5m+5-5=-20-5
5m = -25
5m/5 = -25/5
m = -5

What is the probability of rolling at least one 5 or 6 when rolling the dice three times?
Answer:
19/27
Step-by-step explanation:
Each time that you roll a dice, there is a 1/3 chance you get a 5/6(assuming you have a fair dice). The probability of rolling that atleast once is the inverse of the probability of rolling a 1-4 each time. There is a [tex]\frac{2}{3}[/tex] chance each time you roll the dice. Thus raising this to the third power results in [tex]\frac{8}{27}[/tex]. Since we are looking for the inverse probability, we can do:
[tex]1-\frac{8}{27}[/tex] In order to get our final answer.

No solutions
Step-by-step explanation:
If we try to solve this system for y at x = 1, we get an impossible situation:
[tex]y=-7(1)+8=-7+8=1\\y=-7(1)-8=-7-8=-15\\1=-15[/tex]
Clearly, 1 ≠ -15, and we'll see that any value of x that we pick gives us two contradictory values for y, so this system has no solutions.

Volume of a shape
Jacob’s dad gave him a soda can to use. He was able to cut off the top to have a full opening. The can is 5 inches tall and the opening has a diameter of 3 inches.
Jacob’s little sister ate her ice cream, but didn’t want to eat the cone. Jacob decided to use the cone to scoop sand and build his castle. The cone is 5 inches long and has an opening diameter of 3 inches
Answer:
The can's volume is 35.34 inches
the cone's volume is 11.78 inches
hope it helps you!!
The question asks for the volume of a cylinder and a cone, both with a height of 5 inches and a diameter of 3 inches. The volume of the cylinder is calculated as approximately 35.34 inches³, and the volume of the cone is about 11.78 inches³.
The question involves finding the volume of two different 3-dimensional shapes: a cylinder (soda can) and a cone (ice cream cone). To calculate the volume of the cylinder, we use the formula V = π r² h, where r is the radius of the circular base, and h is the height of the cylinder.
Since the diameter of the soda can is given as 3 inches, the radius (which is half of the diameter) would be 1.5 inches. For the cone, the formula for volume is V = {1}/{3} π r² h, using the same measurements for r and h as the soda can. The calculations then proceed as follows:
Cylinder: V = π (1.5)² × 5 = π × 2.25 × 5
Cone: V = {1}/{3} π (1.5)² × 5 = {1}/{3} π × 2.25 × 5
The volume of the cylinder would be approximately 35.34 inches³ and the volume of the cone would be about 11.78 inches³, assuming π is approximately 3.14159.
To own and operate a home printer, it costs $100 for the printer and an additional $0.05 per page for ink. To print out pages at an office store, it costs $0.25 per page. Let p represent number of pages.
(1) For the costs to be the same, how many pages do you need to print?
(2) How much does it cost to print that many pages?
Answer:
1.) 500 pages
2.) $125
Step-by-step explanation:
Given that the printer cost $100. To operate at home will cost
100 + 0.05P
To print out pages at an office store, it will cost 0.25P
1.) For the costs to be the same, then
100 + 0.05P = 0.25P
0.25P - 0.05P = 100
0.20P = 100
P = 100/0.2
P = 500 pages
500 pages need to be printed
2.) How much does it cost to print that many pages?
Cost = 0.25P
= 0.25 × 500
= 125 dollars
Answer: (1) You would need to print 500 pages
(2) To print 500 pages from home would cost $125
Step-by-step explanation: The cost of printing at home has been given as a fixed cost of 100 plus an additional variable cost of 0.05 per page for ink, that is, Cost = 100 + 0.05p. Also, to print at the office, the cost has been given as 0.25 per page, that is, Cost = 0.25p.
Therefore for the costs to be the same, we need to equate both cost functions (that is, C = C) as follows;
100 + 0.05p = 0.25p
Collect like terms and we now have,
100 = 0.25p - 0.05p
100 = 0.20p
Divide both sides of the equation by 0.2
500 = p
To print 500 pages at home therefore would cost,
C = 100 + 0.05p
C = 100 + 0.05(500)
C = 100 + 25
C = 125
Therefore to print 500 pages from home would cost $125

Cole is studying employment trends.
He found that 20% of the social workers he surveyed, or 45 social workers,
work part time. How many social workers did Cole survey altogether?
Answer:
225
Step-by-step explanation:
So we know that 20% of the social workers he surveyed was 45 people. The easiest way to find all 100% of the social workers is to do 45 x 5 because 20% x 5 = 100%. So 45 x 5 = 225.
