A circle has a radius of 9 units and a center located at (-5, 2) on a coordinate plane.
Which of the following equations represent this circle?
A (x - 5)2 + (y + 2)2 = 81
B
Kx + 5)2 + (-2)2 = 81
(x - 5)2 + + 2)2 = 3
(x + 5)2 + (-2) = 3
Answer: (x+5)^2+(y-2)^2=81
Step-by-step explanation:
The equation of the circle will be equal to ( x + 5 )² + ( y - 2 )² = 81
What is an equation?The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.
Given that:-
A circle has a radius of 9 units and a centre located at (-5, 2) on a coordinate plane.The equation of the circle will be:-
( x - h )² + ( y - k )² = r²
( x + 5 )² + ( y - 2 )² = 81
Therefore the equation of the circle will be equal to ( x + 5 )² + ( y - 2 )² = 81

PLEASE ANSWER ASAP!!Find a rational function that might have the given graph. (More than one answer might be possible.)
Answer:
The rational function that might have the given graph is [tex]y = - \frac{x}{(x+1)\cdot (x-1) }[/tex].
Step-by-step explanation:
This graph shows a rational function whose numerator is a first order polynomial and denominator is a second order, due to the presence of vertical asymptotes at [tex]x = -1[/tex] and [tex]x = 1[/tex]. The lead coefficient of the numerator must be 1, since horizontal asymptote must be [tex]y = 0[/tex] and intercept must be [tex]0[/tex], since [tex]y(0) = 0[/tex].
Then, we conclude that a rational function that might have the graph is:
[tex]y = - \frac{x}{(x+1)\cdot (x-1) }[/tex] (1)
We present the proof that given function is appropriate.

What is the solution to the system of equations?
y = 3x - 4
2y - 6x = -8
Answer:
Infinite solutions.
Any number.
Step-by-step explanation:
First, substitute one of the variables, x or y into one of the equations.
Since y is already isolated, substitute it in 2y - 6x = -8.
2 (3x - 4) - 6x = -8
Distribute 2 to 3x and -4.
6x - 8 - 6x = -8
Bring like terms together.
6x - 6x - 8 = -8
move -8 over to the other side of the equation and change its sign.
Or just add 8 to both sides (it is the same thing.)
You add 8 because it is to cancel out the negative 8 and get rid of it.
6x - 6x = -8 + 8
This equals 0 = 0 so there are infinite solutions to this system of equations.
The value of y varies directly with x. When y=2 2/5,x=3/5 what is the value of y when x is 4/5
A 1 1/5
B 3 3/5
C 3 1/5
D 5 1/5
Answer:
the correct ans should be 88/15
Step-by-step explanation:
since, y is directly proportional to x then,
y=kx where k=proportionality constant
when y=22/5 and x=3/5
or,22/5=k*3/5
or,22/5*5/3=k
•°•k=22/3
now, when x=4/5
we know,
y=kx
or,y=22/3*4/5
•°•y=88/15
A statistical quality control process for cereal production measures the weight of a cereal box. The population standard deviation is known to be 0.09 ounces. If we wish to estimate the population average cereal box weight to within 0.011 ounces and be 94% confident, how large a sample should be used
Answer:
the sample should be 237
Step-by-step explanation:
The computation of the large the sample be used is shown below:
Given that
Standard deviation = 0.09 ounces
margin of error = 0.011
For 94% confidence interval, the z value be 1.88
As we know that
Margin of error = ((z score × standard deviation) ÷ (Sample size))^2
0.011 = (1.88 × 0.09) ÷ (Sample size))^2
0.011 = 0.1692 ÷ (Sample size))^2
So, the sample size be
= 15.38^2
= 236.60
Hence, the sample should be 237

Pls Convert the following base ten numbers to base six with formula
1. 12
2. 31
3. 41
This is urgent pls as fast as possible
The base ten numbers to base six for the following is
1. 12 (base 10) =20(base 6)
2.31 (base 10) =51(base 6)
3. 41 (base 10) =105(base 6)
The procedure to find the base ten number to base six
We have to divide the number 12 repeatedly by 6 until the quotient becomes 0.
When 12 is divided by 6 the quotient is 2 and the remainder is 0.
When 2 is divided by 6 the quotient is 0 and the remainder is 2.
Now, Write the remainder from top to bottom.
We get [tex]12_{10} =20_{6}[/tex]
Similarly we do, 31 and 41
When 31 is divided by 6 the quotient is 5 and the remainder is 1.
When 5 is divided by 6 the quotient is 0 and the remainder is 5.
Now, Write the remainder from top to bottom.
We get [tex]31_{10} =51_{6}[/tex]
When 41 is divided by 6 the quotient is 6 and the remainder is 5.
When 6 is divided by 6 the quotient is 1 and the remainder is 0.
When 1 is divided by 6 the quotient is 0 and the remainder is 1.
Now, Write the remainder from top to bottom.
We get [tex]41_{10} =105_{6}[/tex]
Therefore, The base ten numbers to base six for the following is
1. 12 (base 10) =20(base 6)
2.31 (base 10) =51(base 6)
3. 41 (base 10) =105(base 6)

If you see marginal cost increasing in a graph, this implies that
a. marginal product must be increasing, too.
b. the additional cost incurred in producing one more unit of output is decreasing.
c. the company is experiencing some inefficiency in production.
d. the productivity of the company is increasing.
If you see marginal cost increasing in a graph, this implies that; b. the additional cost incurred in producing one more unit of output is decreasing.
What is the interpretation of the marginal cost?
The marginal cost is the change in total production cost that comes from making or producing one additional unit.
When marginal product is rising, the marginal cost of producing another unit of output is declining and when marginal product is falling marginal cost is rising. Thus, Option A and D are not correct.
Option C is wrong because Marginal cost helps to increase efficiency in production.
Thus, option B is the correct answer.
