A = -6 and B = 65
Completing the squareFrom the question, we are to express the given expression in the form (x + A)^2+B by completing the square
The given expression is
x² -12x + 101
Using the completing the square method
x² -12x + 101
Divide the coefficient of x by 2 and then square it
The coefficient of x is -12
Dividing by 2, we get
-12/2 = -6

A population of mold decays at a rate of 30 mold spores per day. If the initial population of mold spores is 1560 spores, how many days will it take for the population to be less than 1000 mold spores?
By using a linear equation, we can see that after the 19 day the population will be less than 1000 mold spores.
How many days will it take for the population to be less than 1000 mold spores?We know that the population decays at a rate of 30 spores per day, and we have an initial population of 1560 mold spores.
Then, the population of spores after x days is given by the linear equation:
P(x) = 1560 - 30*x
The population will be exactly 1000 spores when:
P(x) = 1000 = 1560 - 30*x
We need to solve that for x.
30x = 1560 - 1000 = 560
x = 560/30 = 18.67
So after 18.67 days the population is 1000, this means that after the 19 day the population will be less than 1000 mold spores.

1. I am a number between 120 to 130 and I am divisible by 3, 6 and 9. Who am I?
Answer:
126
Step-by-step explanation:
A number is divisible by 3 if its sum of digits is divisible by 3 (you can do it over and over again until it's one digit!).
A number is divisible by 2 if its last digit is 0, 2, 4, 6 or 8.
A number is divisible by 6 if it is divisible by 2 and by 3.
A number is divisible by 9 if its sum of digits is divisible by 9 (you can do it over and over again until it's one digit!).
So we need a number with last digit 0, 2, 4, 6, or 8 (because it's divisible by 6 hence by 2) and with a sum of digits divisible by 9 (because if it's divisible by 9 it's also divisible by 3).
130 is not divisible by 9, so the first digits must be 12X.
to get a number divisible by 9, we need to add a digit D so that 1+2+D is divisible by 9.
9 - 1 - 2 = 6
126 is divisible by 9 because it's sum of digits is 9. It's also divisible by 6, because it is divisible by 3 and its last digit is 6.

f(x) = 20x + 80. A senior citizen pays $20 less than half of
this price for x days. What is the total cost for a senior citizen to
go camping for three days in the park?
The total cost paid by the senior citizen for 3 days = $50
Function word problemsThe function representing the total cost of the annual pass is:
f(x) = 20x + 80
A senior citizen pays $20 less than half of this price for x days
The total cost paid by the senior citizen = [tex]\frac{f(x)}{2} -20[/tex]
The total cost paid by the senior citizen =[tex]\frac{20x+80}{2} -20[/tex]
Simplify the resulting expression:
The total cost paid by the senior citizen =10x + 40 - 20
The total cost paid by the senior citizen = 10x + 20
x represents the number of days
Substitute x = 3 into the resulting equation
The total cost paid by the senior citizen for 3 days =10(3)+20

C with a return rate of 2%. Use a weighted mean to find your average return rate.
Average return rate=
The Average return rate for the investment will be 3.2%.
The Return Rate can be defined as a profit that is made on investment .
In the Question
let the investment be "x" .
25% stocks in Company A have return rate of 6%.
Investment in Company A = (25% of x)
Return is 6% of investment = (25% of x) + 6% of (25% of x)
Return from company A= (25% of x)(1+0.06) ...as 25%=0.25 & 6%=0.06
= 0.25*x*(1.06) ...(i)
40% stocks in Company B have return rate of 2.5%.
Investment in Company B = (40% of x)
Return is 2.5% of investment = (40% of x) + 2.5% of (40% of x)
Return from company A = (40% of x)(1+0.025) ...
= 0.40*x*(1.025) ...(ii)
Stocks in Company C = 100 - 25 - 40 = 35%
35% stocks in Company C have return rate of 2%.
Investment in Company C = (35% of x)
Return is 2.5% of investment = (35% of x) + 2% of (35% of x)
Return from company C = (35% of x)(1+0.02) ...
= 0.35*x*(1.02) ...(iii)
Total Return = Return from Company A + Return from Company B + Return from Company C .
From equation (i) ,(ii) and (iii) we get
Total Return = 0.25*x*(1.06) + 0.40*x*(1.025) + 0.35*x*(1.02)
= 0.265x + 0.41x + 0.357x
= 1.032x
The Average rate of return = [tex]\frac{return- investment }{investment } \times100[/tex]
Substituting the value we get,
= (1.032x - x ) / x *100
= 0.032x /x * 100
= 0.032*100
= 3.2%
Therefore , the Average return rate for the investment will be 3.2%.

So probability that kayla rolls an even number on the red cube and a multiple of 3 on the blue cube is 16.66 ≈ 16%
Given that we have red number cube and blue number cube so as we all know that Probability is the ratio of the favourable number of outcomes to the total number of outcomes is known as Probability.
First, find the possible outcomes.
Kalya has a red number cube and a blue number cube. Each number cube has faces labeled 1 through 6
So, possible outcomes =6×6 =36
Let, S be the sample space.
Then, ⁿ(s) =36
Let, E = the event of getting an even number on the red cube and a multiple of on the blue cube.
E = (2,3),(2,6),(4,3),(6,3),(6,6)
Then, ⁿ(E)=6
Let, P is the probability of the event .
So, P(E)= [tex]\frac{n(E)}{n(S)}[/tex] = [tex]\frac{6}{36}[/tex] = [tex]\frac{1}{6}[/tex] = 16.67 percent or 16[tex]\frac{2}{3}[/tex] %

C. For a value y, it is possible that g (4) = y.
D. The point (4,7) is on the graph of y = g (x).
E. The point (7,4) is on the graph y = g (x).
Answer:
B and D
Step-by-step explanation:
The wording in the answer choices make a huge difference. It is possible implies that there is a possibility
A is false. The range of a function is the output value of the function for the input value in the domain of the function. So we can say with certainty that 7 is in the range since it is an output. But we cannot state that 4 is in the range because we have only one output value 7 for g(4)
A good example is a constant function such as g(x) = 7. Here, whatever the value of x, the y value is always 7. This represents a horizontal line passing through y = 7. So the range is just a single number {7}
B can be true. It is possible but not a certainty that f(a) = 4 for some value of a. For example, consider the function g(x) = x + 3.
At x = 4, g(4) = 4 .1 + 3 = 7
At x = 1, g(1) = 1 + 3 = 4 so it is possible for 4 to be an output
C is false. A well-defined function has only a unique value for a specific input of x. So we cannot get two different values for a single x value.
D is true. Since at x =4, y = g(x) = 7, this corresponds to a point on the graph. The point will be (x=4, y =7) or (4,7)
E is false. The x, y coordinates have been interchanged in this answer choice
The true statements are B and D.
The wording in the answer choices make a huge difference.
It is possible implies that there is a possibility
A. 4 is in the range of g.
A is false.
The range of a function is the output value of the function for the input value in the domain of the function. So we can say with certainty that 7 is in the range since it is an output. But we cannot state that 4 is in the range because we have only one output value 7 for g(4)
A good example is a constant function such as g(x) = 7.
Here, whatever the value of x, the y value is always 7.
This represents a horizontal line passing through y = 7.
So the range is just a single number {7}
B. For a value a, it is possible that g (a) = 4.
B can be true.
It is possible but not a certainty that f(a) = 4 for some value of a.
For example, consider the function g(x) = x + 3.
At x = 4, g(4) = 4 .1 + 3 = 7
At x = 1, g(1) = 1 + 3 = 4 so it is possible for 4 to be an output.
C. For a value y, it is possible that g (4) = y.
C is false.
A well-defined function has only a unique value for a specific input of x. So we cannot get two different values for a single x value.
D. The point (4,7) is on the graph of y = g (x).
D is true.
Since at x =4, y = g(x) = 7, this corresponds to a point on the graph.
The point will be (x=4, y =7) or (4,7)
E. The point (7, 4) is on the graph y = g(x).
False. The statement doesn't provide any information about g(7), and we cannot determine whether the point (7, 4) lies on the graph of the function y = g(x) based solely on the given information.

{(9 / 2, 1 / 4),(4 1 / 2, -4),(0, 5 / 6)}
We can also write it as:
{(9 / 2, 1 / 4),(9 / 2, -4),(0, 5 / 6)}
The domain of the relation will be:
Domain = { 9 / 2 , 0}
The range of the relation will be:
Range = {1 / 4, -4, 6}
We know that every function can be a relation but every relation cannot be a function.
A relation means the connection between the input and the output.
A function means that for every input there should only be one output.
Here, this relation is not a function because:
The input 9 / 2 has 2 outputs as 1 / 4 and -4 which is not possible in a function.
Therefore, we get that it is not a function with domain as { 9 / 2 , 0} and range as {1 / 4, -4, 6}.
