how do you find the radius of a circle when given the central angle and arc length
arc length = 82 central angle = 135 degrees
The radius of a circle is determined as 27.95 units.
What is relation between arc and radius of circle?The arc length formula for a circle is times the radius of a circle. The arc length formula in radians is as follows: arc length = θ × r, where is in radian.Now the formula for the arc length when the central angle is given in the degrees;
arc length = (θ/360°)×(2πr)
Where, r is the radius of the circle and π = 3.14.
Write the formula for r;
r = (arc length/2π)×(360°/θ)
For the given values in question;
arc length = 82 central angle = 135 degrees.
r = (82/2×3.14)×(360°/135°)
r = (13.05)×(2.67)
r = 27.95
Therefore, the radius of the circle is found as 27.95 units.

Write an equation in slope-intercept form of the line that bisects the angle formed by BA and BC
B
v=D
y = -x +2 an equation in slope-intercept form of the line that bisects the angle.
What exactly does slope intercept mean?
A method of formulating a line's equation that makes it simple to identify the slope and y-intercept is known as the slope-intercept form. The point where the line crosses the y-axis is known as the y-intercept, and the slope refers to how steep the line is.Given:
Angled formed by ray BA and ray BC is 90 degrees.
To find:
The equation of line that bisects the angle formed by ray BA and ray BC.
If a line bisects the angle formed by ray BA and ray BC, then it must be passes through point B and makes angles of 45 degrees with ray BA and ray BC.
It is possible if the line passes though point B(-1,3) and other point (-2,4).
Equation of line is
y - y₁ = y₂ - y₁/x₂ - x₁ ( x - x₁)
y - 3 = 4 - 3 / - 2 - ( -1) ( x - ( -1)
y - 3 = 1/-1 ( x + 1 )
y - 3 = -x -1
Add 3 on both sides
y = -x -1 + 3

I need to find out if this is a horizontal or vertical compression/stretch and by what factor and also if it is a vertical, up or down, or horizontal, left to right, translation -4f(x)
The transformation rule f(x) → - 4 · f(x) is the consequence of combining a reflection about the x-axis and a vertical stretch.
What kind of rigid transformation is behind a transformation rule?
According to the statement, we must conclude what kind of rigid transformations are behind the transformation rule f(x) → - 4 · f(x). Rigid transformations are transformations applied on a function such that its form is not altered. The most common transformations are listed below:
Horizontal translation: f(x) → f(x - k), right when k > 0.Vertical translation: f(x) → f(x) + k, up when k > 0.Horizontal compression: f(x) → f(k · x), 0 < k < 1Horizontal stretch: f(x) → f(k · x), k > 1Vertical compression: f(x) → k · f(x), 0 < k < 1Vertical stretch: f(x) → k · f(x), k > 1Reflection about the x-axis: f(x) → - f(x)Reflection about the y-axis: f(x) → f(- x)Then, we find that the transformation rule f(x) → - 4 · f(x) is the consequence of combining a reflection about the x-axis and a vertical stretch.

if so, we have
(-3(2x - 6) + 5x)/6 = 7 + (2(-4x + 1) - 6)/3
now, I usually remove the fractions first by multiplying both sides with both denominators :
1. multiply by 6
-3(2x - 6) + 5x = 42 + 6(2(-4x + 1) - 6)/3
2. I can skip the general multiplication by 3, because the denominator 3 goes away in interaction with the new factor 6
-3(2x - 6) + 5x = 42 + 2(2(-4x + 1) - 6)
now, we do all the multiplications and see what we get :
-6x + 18 + 5x = 42 + 2(-8x + 2 - 6) =
= 42 - 16x + 4 - 12
-x + 18 = -16x + 34

Use the properties of logarithms to evaluate each expression. 2 log 5+ log 40
The result obtained for the logarithms expression 2 log 5+ log 40 is 3.
What are the logarithmic functions defined as?The logarithm of a number is the exponent by which a fixed value recognized as the base must be raised in attempt to calculate that number. Because 1000 is ten to the third power, this same log of 1000 to base ten is three.
There is no such thing as a y-intercept.x = 0 is a vertical asymptote. *Note: An asymptote is a line that a graph reaches as absolute value of x as well as y increases.A logarithmic function has no horizontal asymptote.The value of the x-intercept is one.The function is spreading throughout the domain.If the base is between 0 and 1, the function reduces out over the domain.Some rules of the logarithmic functions are-
Quotient Rule: ㏒(A/B) = ㏒A - ㏒BProduct Rule : ㏒A + ㏒B = ㏒(AB)Power Rule: n㏒A = ㏒AⁿBase Rule = ㏒ₐb = ㏒ₓb/㏒ₓaExponent Rule = e∧lnx = xnow, the given expression to be evaluated is;
= 2 log 5+ log 40
Apply the Power Rule in the first term;
= log 5²+ log 40
= log 25+ log 40
Now, using the Product Rule, the expression becomes.
= log (25×40)
= log (1000)
If the base is taken as 10, then the value of the log (1000) = 3.
Therefore, the obtained value of the value of the logarithms expression 2 log 5+ log 40 is 3.

If Ax + By = Cz
If A, B, C, x, y, and z are all positive integers then A, B, and C should all have a common prime factor.
A common prime factor means that each of the numbers needs to be divisible by the same prime number. So 15, 10, and 5 all have a common prime factor of 5 (they're all divisible by the prime number 5).
So far, so simple, and it looks like something you would have solved in high school algebra.
But here's the problem. Mathematicians haven't ever been able to solve the Beale conjecture, with x, y, and z all being greater than 2.

Determine whether each function is an example of exponential growth or decay. Then find the y -intercept.
y=7/8(18)x
The function y = 7 / 8 ( 18 ) ˣ is an exponential growth function.
An exponential function is defined as y = a ˣ where x is a variable, and a is a constant called the base of the function.
We are given a function:
y = 7 / 8 ( 18 ) ˣ
We need to tell whether is is a exponential growth or decay function.
We can see that the value of a ˣ = (18) ˣ
So, the value of a = 18.
Since, it is an integer and not a fraction, its value will increase with the increase in exponent x.
So, it will be a exponential growth function.
Therefore, we get that, the function y = 7 / 8 ( 18 ) ˣ is an exponential growth function.

If Annie can mow 1/6 of an acre in 50 minutes, then in an hour, she can mow 1/5 of an acre.
How many acres can Annie mow per hour?Given the data in the question;
Annie can mow 1/6 of an acre in 50 minuteshow many acres can she mow per hour?Let x represent the number of acres that Annie can mow in hour.
Also convert 1 hour to minutes
1 hour = (1 × 60)min = 60min
Annie can mow 1/6 of an acre in 50 minutes
Annie can mow x of an acre in 60 minutes
Hence;
1/6 × 60 = x × 50
60/6 = 50x
50x = 60/6
50x = 10
x = 10/50
x = 1/5

The factors for the given expression will be calculated based on two factors -
1. The sum of factors should be equal to sum of numeral value of b (11 in this case)
2. The product of factors should be equal to product of numeral values of a and c (24 in this case)
As per the above rules, the appropriate factors should be 8 and 3.
Rewriting the given equation with possible factors -
4x² + 8x + 3x + 6 = 0
Taking common values
4x(x + 2) +3(x + 2) = 0
(x + 2) (4x + 3) = 0
x = -3/4, -2
Thus, the factors of given expression are -3/4 and -2.
To check the correctness of factors, we will keep each value of x in equation.
When x = -3/4
4x² + 11x + 6 = 0
4(-3/4) + 11(-3/4) + 6 = 0
9/4 -33/4 + 6 = 0
9/4 = 2.25 and 33/4 = 8.25
2.25 - 8.25 + 6 = 0
-6 + 6 = 0
0 = 0
When x = -2
4x² + 11x + 6 = 0
4(-2)² + 11(-2) + 6 = 0
16 - 22 + 6 = 0
22 - 22 = 0

What is a rational number?
Any real number that can be represented in the form of p/q, where q is not equal to 0 is called a rational number. The decimal expansion of rational numbers is terminating and repeating.
Simplifying the rational expression: x² + 3x - 10 / x² + 4x - 12 . 3x + 18 / x + 3
Given a rational expression,
x² + 3x - 10 / x² + 4x - 12 . 3x + 18 / x + 3
On simplifying, we get,
(x² + 3x - 10).(3x + 18) / (x² + 4x - 12).(x + 3)
For numerator, (x² + 3x - 10).(3x + 18), we have,
= 3(x + 5)(x - 2)(x + 6)
For denominator, (x² + 4x - 12).(x + 3)
= (x + 6)(x - 2)(x + 3)
Now, (x² + 3x - 10).(3x + 18) / (x² + 4x - 12).(x + 3) = 3(x + 5)(x - 2)(x + 6) / (x + 6)(x - 2)(x + 3)
