Arc: The length of any arc is s = r θ , where is the length of the arc, is the radius, and is the measure of the angle in radians. Use the fact that is equal to to convert between degrees and radians. A subtended arc is the part of the circle in between the two rays that make the central angle.
Arc length formula is used to calculate the measure of the distance along the curved line making up the arc (a segment of a circle). In simple words, the distance that runs through the curved line of the circle making up the arc is known as the arc length. It should be noted that the arc length is longer than the straight line distance between its endpoints.

The evaluations of the quadratic equation at the values of 0, 7 and - 5 are 5, 1356 and - 460, respectively.
How to evaluate a polynomial function
In this question we have the definition of a quadratic equation, which has to be evaluated at three distinct values of x. Evaluating a function consists in substituting the independent variable by a value and simplify the expression. Now we proceed to evaluate the function:
f(0) = 4 · 0³ - 7 · 0 + 5
f(0) = 5
f(7) = 4 · 7³ - 7 · 3 + 5
f(7) = 1372 - 21 + 5
f(7) = 1356
f(- 5) = 4 · (- 5)³ - 7 · (- 5) + 5
f(- 5) = - 460

This in other words mean the range of a function is the set of y values of the graph.
How to determine the value of x that cannot be evaluated in the function F(x)?The function is given as
f(x) = (x + 13)/(x - 3)
Set the denominator of the function to 0
So, we have
x - 3 = 0
Evaluate the equation
x =3
This means that x =3 is not in the domain of the function
Hence, the value of x that cannot be evaluated in the function F(x) is 3

there are two rates that relate meters and kilometers. in the second Model it, why is 1/1000 the unit rate that is used to convert 3,200 meters to kilometers
3200 meters by using the units of conversion will be equal to 3.2 km.
We are given:
3200 meters.
We know that the unit of conversion for the meters and kilometers is given by:
1 km = 1000 m
1 m = 1 / 1000 km
For 3200 m, we will use the operation of multiplication.
So, we get that:
3200 m = 1 / 1000 × 3200 km
3200 m = 3.2 km.
Therefore, we get that, 3200 meters by using the units of conversion will be equal to 3.2 km.

The statements that are also valid based on the proportion are given as follows:
(m/p) = (n/q).(n/m) = (q/p).(q/n) = (p/m).How to obtain the valid statements?
The proportion for this problem is given as follows:
(m/n) = (p/q).
Applying cross multiplication, the proportion can also be written as follows:
mq = pn.
Then each statement in which the application of cross multiplication results in this product is valid.
Thus the third, fourth, and fifth options are the correct options, as the application of the cross multiplication for each of them results in the expression mq = pn.
For the first, second and sixth statements, they are not valid, as the application of cross multiplication would result in a different expression to mq = pn.

let me give you a mouthful of something
the domain of f(x) is the range of its inverse, or namely the domain of f(x) is the same set as the range of f⁻¹(x), so for any (a , b) pair on the domain of f(x), there's a (b , a) on the range of f⁻¹(x).
now, that's a bit of of a mumble, but in short it means, if f(x) has a point of (3 , 5), then the graph of f⁻¹(x) has a point which is the same pair but flipped sideways, namely (5 , 3).

Twice the difference of m and 12 gives 72.
translate to algebraic equation
Answer:
[tex]2(m - 12) = 72[/tex]
Step-by-step explanation:
Part 1) "The difference of m and 12"
This simply means subtracting 12 from m. Therefore, we get [tex](m - 12)[/tex].
Part 2) "Twice the difference of m and 12"
This means we should double the same difference we got in Part 1. Therefore, we get [tex]2(m - 12)[/tex].
Part 3) "gives 72"
Finally, we are given that the algebraic expression we found under Part 2 should be equal to 72. Therefore, we get [tex]2(m - 12) = 72[/tex]
Suppose that two balls are selected with replacement from a bag that contains 10 white and 5 black balls. What is the probability that both balls are black?
The probability that both the balls are black is [tex]\frac{1}{9} \\[/tex] .
Probability is the section of mathematics which deals with the likelihood of an event happening.
The value of probability is a fraction which always lies between 0 and 1. it is defined as the ratio of the favorable outcomes of an event to the total outcome of an event.
Given the bag has 10 white balls and 5 black balls. Therefore the total number of balls in the bag is 15 .
Hence the sample space is 15 .
The balls are drawn with replacement. Therefore for the first ball pick:
Number of favorable outcomes = 5
Total number of outcomes = 15
Probability = favorable outcome ÷ total outcome
Therefore [tex]P_1=\frac{5}{15}=\frac{1}{3}[/tex]
Now the ball is placed back and the second ball is picked.
Number of favorable outcomes = 5
Total number of outcomes = 15
Probability = favorable outcome ÷ total outcome
Therefore [tex]P_2=\frac{5}{15}=\frac{1}{3}[/tex]
Now the total probability that both the balls are black is :
P = P₁×P₂
[tex]P=\frac{1}{3}\times \frac{1}{3}\\\\P=\frac{1}{9}[/tex]
Hence the probability of picking two black balls is [tex]\frac{1}{9} \\[/tex] .

How many times hotter is the Red Savina Habanero than the Thai Pepper?We know that the Thai Pepper has a hotness rating of 7.5*10⁴, while the Red Savina Habanero has a hotness rating of 4.6*10⁵.
We want to see how many times hotter is the Red Savina Habanero than the Thai Pepper, to find that we need to take the quotient between the rating for the Habanero and the rating for the Pepper.
It gives:
Q = (4.6*10⁵)/(7.5*10⁴)
This can be rewritten as:
Q = (4.6/7.5)*(10⁵/10⁴)
=0.613*(10 ⁵⁻⁴) = 0.613*10
Now, we want to write this in scientific notation, so we need to have a single digit different than zero in the left side of the decimal point.
