find the radian measure of the central angle of a circle of radius r that intercepts an arc of length s.
The central angle in radians is given by θ = s/r, where s is the arc length and r is the radius of the circle
For given question,
we need to find the radian measure of the central angle of a circle of radius r.
The central angle intercepts an arc of length s.
Let θ be the central angle in radians.
We know that the arc length of circle of radius r is,
s = r × θ
where s is the arc length
r is the radius of the circle
θ is the central angle measured in radians
From above equation,
we have, θ = s ÷ r
Therefore, the central angle in radians is given by θ = s/r, where s is the arc length and r is the radius of the circle

What is the value of X?
Answer:
61 degrees
Step-by-step explanation:
180 - 58 = 122
Since both sides are congruent, 122/2 = 61
Answer:
61
Step-by-step explanation:
Since ED and EF are congruent, Angle D = Angle F meaning angle F is also x degrees.
From here, we can use the total sum of angles in a triangle = 180 to calculate x:
180 = 58 + x + x
180 = 58 +2x
122 = 2x
x= 61 degrees
What is the
Measure of angle B in degrees?
Answer:
B = 119! The answer is 119!
Step-by-step explanation:
Determine which equation represents a function.
A. y = -2x + 1
B. x=4
C. x=y²-1
D. y²-x
The equation that represents a function is (A) y = -2x + 1.
A Function is defined as an equation for which any "x" we substitute in the equation will give only one output such as "y"
it is denoted by y=f(x).
In the given question
Option (A)
y=-2x+1
Yes the given equation is a function ,
because when we substitute a value in x ( let x=2) it gives only a single output (y=-3).
Hence , y=-2x+1 is a function .
Option (B)
x=4
No, it is not a function as ,
x=4 is a vertical line parallel to y axis ,
we know that for a function every value of x will have exactly one y .
For x=4 , y can 0 , -9 , 6 .
Hence , x=4 is not a function.
Option (C)
x=y²-1
No. it is not a function ,
we know that for a function every value of x will have exactly one y .
For x=0 , y=+1,-1 .
Hence , x=y²-1 is not a function .
Option (D)
y²-x
No , it is not a function
As y²-x do not have an equal to sign "=" , it cannot be considered as an equation.
Hence , y²-x is not a function .
Therefore , Only y = -2x + 1 represents a function , the correct option is (A) y = -2x + 1

Answer: $21000
Step-by-step explanation:
By uwing option A, the salesperson will make (40 × $21) = $840.
Let the amount of sales that is needed for the week to be thesame as option A be x. Therefore,
4% of x = $840
4% × x = $840
0.04x = $840
x = $840/0.04
x= $21000
The salesperson need to sell $21,000 worth of sales

In a recent year, Major League Baseball player Jack Wilson's batting average was 0.308. Melvin Mora hit safety 17 out of every 50 at-bats and Bobby Abreu hit safety 30.1% of the time. Find Mora's and Abreu's batting averages and order all three averages from least to greatest.
Answer:
Bobby Abreu (0.301) < Jack Wilson (0.308) < Melvin Mora (0.34)
Step-by-step explanation:
Jack Wilson = 0.308
Melvin Mora's average = Number of hits / Total number = 17 / 50 = 0.34
Bobby Abreu = 30.1% = 30.1 / 100 = 0.301
In order of least to greatest;
After coomparing all three batters;
Bobby Abreu (0.301) < Jack Wilson (0.308) < Melvin Mora (0.34)

Ms. deng can walk 1 mile in 20 minutes. her sister can walk 2 miles in 1 hour. who walks faster? why? show all work.
Answer:
she is faster
Step-by-step explanation:
first find how long sister takes to walk 1 mile - if she walks 2 miles in 1 hour she'll take less time to walk 1 mile, 2/2 = 1 mile
and 60mins/2 = 30mins
so sister walks 1 mile in 30 minutes and she walks 1 mile in 20 mins so she is faster by 10 mins
hope this helps :)

a. When x = -1, what is the value of y?
Continue on the following page.
b. When y = 7, what is the value of x?
c. What is the y-intercept of the graph?
d. What is the x-intercept of the graph?
e. What is the slope of the line?
f. What is the equation of the line?
Answer:
a. y = 3
b. x = 1
c. y-intercept = 5
d. x-intercept = -2.5
e. 2
f. y = 2x + 5
Step-by-step explanation:
Based on the graph, we can see the point where x is -1, y = 3.
Based on the graph, we can see the point where y = 7, x = 1.
Based on the graph, we can see the y-intercept is 5.
Based on the graph, we can see the x-intercept is -2.5.
To calculate the slope of the line, I will be using the points (-1, 3) and (0, 5).
Slope = [tex]\frac{rise}{run}[/tex]
= [tex]\frac{5-3}{0-(-1)}[/tex]
= [tex]\frac{2}{1}[/tex]
= 2
The equation of a line is: y = mx + c where m is the slope and c is the y-intercept. Thus, the equation of the line in this case is: y = 2x + 5

(r+1)th term of [tex](a+b)^n[/tex] is given by:-
[tex]T_{r+1}=\ ^nC_r(a)^{n-r}b^r[/tex]
For [tex](a+b)^6[/tex] , n= 6

Answer: 7 and 8
Step-by-step explanation:
Square root and squared cancel out
Answer:
a=7
b=32
Step-by-step explanation:
The first one (a) is 7 because if you square a square root, you get the number inside the root. Also, technically a square root has an exponent of (1/2) so when you have a power-to-a-power (power rule of exponents) you multiply the exponents. So ([tex]7^{1/2}[/tex])^2 is 7.
For (b) you have to take it in two parts. Square the square root and you get 2. Square the 4 in front, you get 16. Multiply those two numbers (16 and 2) together and you get 32.
Edit: Check on your calculator, you get the same answers I got! :)
Given trapezoid ABCD whose bases are segment AB and segment CD, what is mZB?
Answer:
x = 19
<B = 125°
Step-by-step explanation:
The sum f angle <D and angle <A is equal to 180° because these angles are supplementary
75° + 5x + 10 = 180° add like terms
85 + 5x = 180 subtract 85 from both sides
5x = 95 divide both sides by 5
x = 19
Same rule goes for angle <C and angle <B
<B + 55° = 180 subtract 55 from both sides
<B = 125°
Atticus is examining the equations: 4x + 2y = 10 and y = -2x + 5. He states that the equations are equivalent. Is he correct why or why not?
Answer:
He is correct
Step-by-step explanation:
Put the first equation into y = mx + b by isolating y:
4x + 2y = 10
2y = -4x + 10
Divide each side by 2:
y = -2x + 5
So, putting the first equation into y = mx + b got us the same equation as the second one, y = -2x + 5.
Since they are the same, the equations are equivalent.
Atticus is correct.
