What are x and y if angle A is (2x), angle B is (y+x), and angle C is (y-x)?
Value of x is 30 and y is 30, if angle A is (2x), angle B is (y+x), and angle C is (y-x).
Define angle.The names of fundamental angles include acute, obtuse, right, straight, reflex, and full rotation. A geometrical shape called an angle is created by connecting two rays at their termini. In most cases, an angle is expressed in degrees. In geometry, there are several different kinds of angles. a geometric shape made up of two lines that meet at the same point or two planes that meet at the same line. the distance in degrees between such lines or planes.
Given
Angle A = 2x
Angle B = y + x
60 = y + x
y = 60 - x
Angle C = y - x
60 = y - x
60 + x = y
As we know, sum of triangle is 180
2x + 60 - x + 60 + x = 180
2x - x + x = 180 - 120
2x = 60
x - 30
For value of y, equating value of x in y = 60 - x
y = 60 - 30
y = 30
Value of x is 30 and y is 30, if angle A is (2x), angle B is (y+x), and angle C is (y-x).

A 4-cylinder engine with 543 Cubic Centimeters volume per cylinder has what approximate displacement?
Answer:
you would times them both so 4x543 =2172
Step-by-step explanation:
543 cubic centimeters has 0.543 L approximate displacement.
What is Engine displacement?Engine displacement means the displacement of the piston inside cylinder from Bottom Dead Center into Top Dead Center in one cycle.
Basic formula to calculate engine displacement is =
V = π/4 x D² x H x N
Where :
D = Bore Diameter
H = Length of Stroke
N = Number of Cylinder
Since the question has already stated cubic centimeter, it has already shown the displacement. So, we can ignore above formula and the 4-cylinder engine information.
First, we state what is known. It is the displacement at cubic centimeter.
Cubic centimeter = 543 cc
Next, we change the unit of cubic centimeter (cc) into liter (L)
Displacement = cc / 1000 L
= 543 / 1000 L = 0.543 L

When the sequence limn→∞ (1 n! ∫x t = a f(n+1)(t)(x−t)n d t) converges to zero, as seen on the left side equation the Taylor series will accurately converge to f(x). For the Taylor series of f, this side is known as the integral form of the remainder (x).
What is Taylor's formula with remainder?Rn(x) = f(n+1)(c) (n + 1); thus, (x a)n + Rn(x)! when there is a c between a and x, (x a)n+1. The Taylor formula is the name given to the second equation. The residual of order n or error term for the Pn(x) over I approximation of f is known as the function Rn(x) (x). To integrate a Taylor Series function, expand the Taylor Series as usual before integrating each term. There is a general expression for the new series. Prior to determining the generic phrase, it is essential to avoid simplification.
Assume that f(x) is a real or composite function and that f(x) is a differentiable function of a real or composite neighborhood number. The following power series is then described by the Taylor series: F (x) = F a F ′ a 1! (x−a)+f”(a)2!

Create a proportion using the form %/100= is/of to represent the following word problem:
15 is 1 1/2 % of what number?
Answer:
To create a proportion using the form %/100 = is/of, we can first write the given information in the form %/100 = is/of. In this case, we know that 1 1/2% represents 15, so we can write:
1 1/2%/100 = 15/of
Next, we need to solve for the "of" value, which is the number we are trying to find. To do this, we can multiply both sides of the equation by 100 and then divide both sides by 1 1/2% to get:
(1 1/2%/100) * 100 = (15/of) * 100
of = (15/1 1/2%) * 100
Finally, we can evaluate the right-hand side of the equation to find the value of "of". Since 1 1/2% is the same as 1.5%, we can substitute 1.5 for 1 1/2% in the equation to get:
of = (15/1.5%) * 100
of = (15/0.015) * 100
of = 1000
Therefore, the number we are trying to find is 1000.
In summary, the proportion that represents the given word problem is:
1 1/2%/100 = 15/1000
Answer:

What is a function in mathematics?A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences. German mathematician Peter Dirichlet initially offered the standard concept of function in 1837.
y and x are coupled in such a way that there is a distinct value of y for each value of x, and this relationship is frequently represented as y = f(x), or "f of x." In other words, the same x cannot have more than one value for f(x).
We need to check by substituting value of y in every equation to check correct option.
(a) Substituting y=6 and x=3 in function
L.H.S = 6
R.H.S = 3x= 3×3=9
L.H.S≠R.H.S
So, it is not a correct option.
(b) Substituting y=6 and x=3 in function
L.H.S = 6
R.H.S = x-3= 3-3=0
L.H.S≠R.H.S
So, it is not a correct option.
(c) Substituting y=6 and x=3 in function
L.H.S = 6
R.H.S = x+2= 3+3=5
L.H.S≠R.H.S
So, it is not a correct option.
(d) Substituting y=6 and x=3 in function

A bank teller hourly wage will increase from $18 to $21.60. What percent increase does this represent?
The percentage increase is about 16.66%.
What is a percentage increase?
The percentage increase formula is the ratio of value increased to the original value and multiplied by 100. It is expressed in percentage. If there is an increase in the value of anything, then there is an increase in the percentage.
The initial amount was $18 and the final amount is $21.60.
By using the percentage increase formula, we can write
Percentage increase = (final value - initial value)/|Final value| * 100
= ((21.60 - 18)/21.60)*100
= 16.66%

Step-by-step explanation:
A bus company took a tour bus on the ferry when there were 30 people aboard. The ferry charged the bus company $180. The following week, the bus had 50 people on board and the ferry charged them $220. How much is the "base rate" for the empty bus? hint: look at the difference between number of people and cost to get cost per person and then cost without people
How much does each person cost?
Write an equation to show cost, c, of a bus with x number of people on it.
1) The base rate for the empty bus is $120.
2) The variable cost (slope) for each person on board the bus is $2.
3) An equation to show the cost, c, of a bus with x number of people on it is C = 120 + 2x.
How the base rate and slope for the equation are derived:The total charge for taking 30 people aboard = $180
The total charge for taking 50 people on board = $220
The differences in the number of people and charges are 20 and $40, respectively.
Let x = the number of people boarding the bus and n = the fixed rate per bus.
30x + n = 180 ... Equation 1
50x + n = $220 ... Equation 2
Subtract Equation 1 from Equation 2:
20x = $40
x = $2 ($40/20)
The variable cost per person = $2 ($40/20)
The base rate for the empty bus = 30(2) + n = $180, where n is the base rate or fixed cost per bus.
= 60 + n = $180
n = $120
OR:
50(2) + n = $220
100 + n = $220
n = $120

To get the area of your shaded section, you would just need to add up the areas of the 4 semi circles and 2 equi. triangles.
To get the area of a semi circle, work out the area of one of the sectors, i.e sector ABC, then subtract area of an equilateral triangle.
(Note, due to symmetry all semi circles have same area)
________________________________________________________
For example, for the picture below:
Area of equi triangle = absinC = 1*1*sin60 = √(3) --> (C is angle)
Area of sector = (angle/360) * πr² = (60/360) * π * (1)² = π/6
So area of 1 semi circle = Area of Sector - Area of equi triangle
= π/6 - √(3)
Now you would just add the areas of 4 semi circles, and 2 equi triangles, and compare coefficients to get a, b, c.

Now you would do the same for your question, except radius is now 6cm instead of 1cm.

give a big-o estimate for each of these functions. for the function g in your estimate f (x) is o(g(x)), use a simple function g of smallest order. of(x)
The big-o estimate for each of these functions are:
nlog(n^2 + 1) = o (n^2 logn)
What is the big O notation?It is a commonly used notation in algorithms and data structures domain to get an approximate upper bound of the time the algorithm in question will take to run.
For example, if you want to find the maximum element in a list of n elements, the worst case scenario is that the maximum is the last number. Then we write O(n) .
How do you calculate big O notation for a function?If the function is not too unweildy, it's pretty easy to do.
Consider the function f(x) = 4x^3 + (7x^2)(log(x)) + 3x +8
Look for the highest order term - the term that grows faster than the other terms, as x gets larger. For this function, that term is 4x^3.
Now just get rid of the constant out front to get x^3.
Then put a Big O in front: O( x^3 ).
So we say that f(x) is O( x^3 ).
Since,
nlog(n^2 + 1 ) + n^2 logn is approximately equals to n^2logn
which implies,
nlog(n^2 + 1) + (n^2 logn) = O (n^2 logn)

PLEASE HELP ME SOMEONE!!!
Enola wants to invest $8,600.00 in a savings account that pays 5.1% simple interest.
How many years will it take for this investment to triple in value?
Round your answer to the nearest tenth of a year.
It will take ________ years for this investment to triple in value.
Step-by-step explanation:
To find the number of years it will take for Enola's investment to triple in value, we can use the formula for simple interest:
I = P * r * t
where I is the total interest earned, P is the principal (the initial amount invested), r is the interest rate, and t is the number of years.
Since the investment will triple in value, the total interest earned will be equal to two times the initial investment, or 2 * $8,600.00 = $17,200.00. Substituting these values into the formula and solving for t, we get:
$17,200.00 = $8,600.00 * 5.1% * t
t = $17,200.00 / ($8,600.00 * 5.1%) = 3.28 years
Rounding this value to the nearest tenth of a year, we get t = 3.3 years. Therefore, it will take approximately 3.3 years for Enola's investment to triple in value.
Work out angle bcc give a reason for each angle you work out
Answer:
70 degrees
Step-by-step explanation:
Triangle XBC is an isosceles triangle.
From the question given, you already know that angle XBC = 55 degrees. This means that angle XCB = 55 degrees. This is because the two sides XB and XC are of equal length, which means that the angles are also equal to each other.
Using this info, we can calculate angle BXC:
The sum of a triangle adds up to 180, so call the unknown angle x:
55 + 55 + x = 180
110 + x = 180
x = 180 - 110 = 70 degrees
