Both chords are the same distance from the center of the circle ( the 12 inch lines are the same length).
This means that both chords are the same length. The bottom chord has a dimension of 22.5.
B id half the top chord so would be equal to half of 22.5
b = 22.5 / 2 = 11.25

8) 5x^3 + xy^2= 5x^3y^3
9)y=(3x^4+5x^3-5)/2x^4-4
Answer:
7. (4x - 3xy^2 - 2y) / (3x^2y + 2x).
Step-by-step explanation:
Implicit differentiation:
7. 3x^2 y^2 = 4x^2 - 4xy
6x * y^2 + 3x^2 * 2y y' = 8x - 4(x y' + y)
6xy^2 + 6x^2y y' = 8x - 4x y' - 4y
6x^2y y' + 4x y' = 8x - 6xy^2 - 4y
y' = (8x - 6xy^2- 4y) / (6x^2y + 4x)
y' = 2(4x - 3xy^2- 2y) / 2(3x^2y + 2x)
= (4x - 3xy^2 - 2y) / (3x^2y + 2x).

Chris lost $5.29 playing poker in one week. If this continued, what would be his net winnings or losses after five weeks ?
Answer:
$26.45
Step-by-step explanation:
If Chris lost $5.29 playing poker in one week, in five weeks he would lose $26.45.
$5.29 lost per week.
5 weeks.
$5.29 x 5 = $26.45.
The net loss of Chris after five weeks will be $26.45.
Average value per week: -$5.29
Net loss after five weeks: -$5.29 x 5 = -$26.45
Angelo, Brandon, and Carl work in the same office. Angelo’s age is 4 years more than twice Carl’s age. Brandon is 5 years younger than Carl. The average of the three ages is 41.
Part A: Use a variable to define the age of one of the men.
Part B: Use the variable in part A to represent the ages of the other two men.
Part C: Write an equation that represents the average of the three men's ages equivalent to 41.
Part D: Find the age of each of the men.
Answer:
Angelo is 66 Brandon is 26 Carl is 31
Step-by-step explanation:
Variables a=Angelo b=Brandon c=Carl
Equation (1/3)(a+b+c) = 41
The age of each man is Carl (31), Angelo (66), and Brandon (26).
Explanation:Part A: Let's use the variable x to represent Carl's age.
Part B: Angelo's age is 4 years more than twice Carl's age, so we can write his age as 2x + 4. Brandon is 5 years younger than Carl, so his age is x - 5.
Part C: The average of the three ages is given as 41, so we can write the equation (x + 2x + 4 + x - 5) / 3 = 41.
Part D: To find the age of each man, we solve the equation:
(x + 2x + 4 + x - 5) = 3 * 41
4x - 1 = 123
4x = 124
x = 31
Carl's age is 31, Angelo's age is 2(31) + 4 = 66, and Brandon's age is 31 - 5 = 26.

A diameter is a line segment whose endpoints are on a circle. It is a special type of chord because it must contain the _____ of the circle HELP!!!!!!!!!!
A diameter is a special type of chord that passes through the center of a circle. It has its endpoints on the circle's circumference, with the center of the circle as its midpoint.
Explanation:In the field of mathematics, a diameter is indeed a special type of chord. The unique characteristic of a diameter, differentiating it from other chords, is that it must contain the center of the circle - that is the definition finds its completion. As a line segment, a diameter has its endpoints on the circumference of the circle and its middle point is the center of the circle. So, when referring to a diameter, you are essentially talking about the largest chord in a circle that passes through the center.

Is the line for the equation y = -8 horizontal or vertical? What is the slope of this
Answer:
Horizontal and it's slope is 0.
Step-by-step explanation:
y=a number is horizontal while x=a number is vertical.
The slope of horizontal lines are 0 because there is no rise.
The slope of vertical lines are undefined because there run is 0.
Slope is equal to rise over run.
y=-8 is horizontal because it represents all the points in the form (x,-8) where x is any real number.
Graph as many points as you want in the form (x,-8), you should see a horizontal line formed. The slope of y=-8 is 0.
Example of points in the form of (x,-8):
(-10,-8)
(-5,-8)
(-1,-8)
(0,-8)
(1,-8)
(5,-8)
(10,-8)
All of these go down 8 units after going left or right however many.
This is a horizontal line 8 units below the x-axis.
Answer:
Horizontal
0
Step-by-step explanation:
No matter what the x value is, the y value is - 8. Make a small table to see what that means.
x y
2 -8
0 -8
- 2 -8
See what's happening?
Look at the y intercept. The y value is - 8 when x = 0. It is also - 8 when x = 2.
Make a rough drawing on a scrap piece of paper. Plot just those 2 points. Roughly. You don't even need a ruler.
What do you see? The line must be going horizontally.
The next question is a little harder. It is not obvious, but you do know that this line either goes horizontally or vertically. So the slope can either be 0 or undefined. There is no third choice.
The general equation is y = mx + b
There is no x in y = - 8
Therefore the slope is 0. That's the only way you could get rid of the x.
You roll a 6-sided die with faces numbered 1 through 6, and toss a coin. What is the probability of rolling a 2 or getting heads
P(2 or H) = P(2) + P(H) - P(2 and H)
What is the probability of getting a 2 P(2)? = 1/6
What is the probability of getting heads P(H)? = 1/2
P(2 and H) is the product of those two events since the events are independent. = 1/6 * 1/2 = 1/12
P(2 or H) = P(2) + P(H) - P(2 and H)
P(2 or H) = 1/6 + 1/2 - 1/12 = 7/12
Which is a rational function?
a. y= x-3^x / x^2. b. y= x^2 - x + 4. c. y= x-5/ 2. d. y= 2/x
ANSWER
d.
[tex]y = \frac{2}{x} [/tex]
EXPLANATION
A rational function is of the form:
[tex]r(x) = \frac{p(x)}{q(x)} [/tex]
where p(x) and q(x) are polynomial functions and q(x)≠0.
The first option contains the exponential function
[tex] {3}^{x} [/tex]
This disqualifies it from being a rational function.
The second and third options are polynomial functions.
By definition, all polynomials are rational functions.
The last option is a typical rational function because it has at least an asymptote.
The most correct choice is
[tex]y = \frac{2}{x} [/tex]
Graph the data in the table below. Which kind of function best
models the data? Write an equation to model the data. Please help ASAP
Answer:
C
Step-by-step explanation:
Try to plug in the first pair of numbers to eliminate some equations, all but C fail to satisfy the equation. So C is the answer.
Answer:
CStep-by-step explanation:
Notice that the table doesn't have an exponential behaviour. Because an exponential function has the point (0,1), because all powers with a null exponent are equal to 1.
Also, notice that the table doesn't show a linear relation, because y-variable has all values positive.
Therefore, the only relation that follows the values of the table is
[tex]y=2.5x^{2}[/tex]
Let's evalue each x-value
[tex]y=2.5(-2)^{2} =2.5(4)=10\\y=2.5(-1)^{2}=2.5(1)=2.5\\ y=2.5(0)^{2}=2.5(0)=0\\y=2.5(1)^{2}=2.5\\y=2.5(2)^{2}=10[/tex]
Therefore, the right answer is C. The given values show a quadratic relation.
A faster way to deduct the quadratic pattern is observing that y-values are symmetric no matter if x-values are positive or negative, that meanst he function is pair, or quadratic.

Answer:
A) 6x2-2x-10
B) 2m+1n-6
C) 170c-68
Step-by-step explanation:
4x2 + 2x2 = 6x2 5x -7x = -2x -7 + -3 = -10
8m - 6m = 2m -2n + 3n = 1n -4 - 2 = -6
34 x 5c = 170 34 x -2 = -68
Answer:
Step-by-step explanation:
a) (4x2 + 5x - 7) + (2x2 - 7x - 3)
This is an addition question. We have to perform addition
The first step is open the parenthesis/brackets.
4x^2+5x-7 + 2x^2 -7x-3
Arrange the terms according to the exponents:
4x^2+2x^2-7x+5x-7-3
Combine the like terms:
6x^2-2x-10
Thus the answer is 6x^2-2x-10
b) (8m - 2n - 4) - (6m - 3n + 2)
We have to perform subtraction:
There is a rule in the subtraction that when you open the brackets then the signs of 2nd bracket will be multiplied by the negative sign:
Open the brackets:
8m - 2n - 4 - 6m+3n-2
Arrange the terms:
8m-6m+3n-2n-4-2
Combine the like terms:
2m+n-6
Thus the answer is 2m+n-6
c) (30+4) (5c-2)
This expression shows the operation of multiplication:
Solve the first parenthesis.
(34)(5c-2)
Now multiply 34 by each term of 2nd bracket:
=170c-68
Thus the answer is 170c-68....

Find the distance between the points. (-4, -2) and (5, 2) ^97 2^14 2^5 ^5
Answer:
The distance between 2 points is √97 or 9.84
Step-by-step explanation:
The distance between two points can be found using distance formula:
[tex]d(x_{1},x_{2})=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]
x₁ = -4, y₁ = -2 x₂ =5 and y₂ = 2
Putting values:
[tex]d(x_{1},x_{2})=\sqrt{(5-(-4))^2+(2-(-2))^2}\\d(x_{1},x_{2})=\sqrt{(5+4)^2+(2+2)^2}\\d(x_{1},x_{2})=\sqrt{(9)^2+(4)^2} \\d(x_{1},x_{2})=\sqrt{81+16}\\d(x_{1},x_{2})=\sqrt{97}[/tex]
So, the distance between 2 points is √97 or 9.84
Answer:
=sqrt(97)
Step-by-step explanation:
The distance between the two points is found by
d = sqrt(( x2-x1)^2 + (y2-y1)^2)
= sqrt( ( 5--4)^2 + (2--2)^2)
= sqrt( ( 5+4)^2 + (2+2)^2)
= sqrt( ( 9)^2 + (4)^2)
= sqrt( 81 + 16)
=sqrt(97)

What is the remainder when 3x^4 +2x^3-x^2+2x-24)/(x+2)
Answer:
remainder = 0
Step-by-step explanation:
Using the Remainder Theorem
Given f(x) divided by (x + h) then the remainder is found by evaluating f(- h)
Here the divisor is (x + 2), hence evaluate at h = - 2
Let f(x) = 3[tex]x^{4}[/tex] + 2x³ - x² + 2x - 24, then
f(- 2) = 3[tex](-2)^{4}[/tex] + 2(- 2)³ - (- 2)² + 2(- 2) - 24
= 3(16) + 2(- 8) - 4 - 4 - 24
= 48 - 16 - 4 - 4 - 24 = 0 ← Remainder
Remainder = 0 , hence (x + 2) is a factor of f(x)

Robin earned twice as much money this week as she did last week. Let d represent the amount of money she earned last week. Write a variable expression to represent how much money she earned this week? *
Answer:
2d=m
Step-by-step explanation:
d represents the amount of money she earned Last weekm represents the amount of money she earned this week2xd=m
The variable expression that represents the money Robin earned this week, if 'd' is the money she earned last week, is '2d'. This is because Robin earned twice as much this week as she did the previous week.
Explanation:In the context of this question, Robin earned twice as much money this week as she did last week. Because last week's earnings are represented by the variable, the expression to represent this week's earning becomes 2d. The number 2 is multiplied by d because Robin earned double this week of what she earned last week. Therefore, 2d accurately represents Robin's earnings for this week, if d is the amount she earned last week.
