Suppose that the function g is defined, for all real numbers, as follows.
Find g (-2), g (1), and g (4).
Answers
The values of the functions, when g is defined for all real numbers is as follows:
g(-2) = -3
g(1) = 3
g(4) = 0
Given, the function g is defined for all real numbers.
g(x) = { 1x²/4 - 4 if x≠1
3 if x=1 }
g(-2):
here, x = -2
where x ≠ 1
therefore, g(-2) = 1x²/4 - 4
substitute x as -2
g(-2) = 1(-2)²/4 - 4
g(-2) = 4/4 - 4
g(-2) = 1 - 4
g(-2) = -3
g(1):
here, x = 1
where x = 1
therefore, g(1) = 3
g(4):
here, x = 4
where x ≠ 1
therefore, g(4) = 1x²/4 - 4
substitute x as 4
g(4) = 1(4)²/4 - 4
g(-2) = 16/4 - 4
g(-2) = 4 - 4
g(-2) = 0
Hence we get the values of g(-2), g(1) and g(4) as -3,3 and 0 respectively.

12 Bernadette has recently opened her own soup store. It costs her $360 a month plus $2.50 for each bowl of soup she makes. Bernadette brings in $5.50 on each bowl of soup she sells. How many bowls of soup would Bernadette need to sell to make money each month? Explain.
Answers
Answer:
So, to make money each month, Bernadette would need to sell at least 121 bowls of soup.
Step-by-step explanation:
Cost function:
Has a fixed cost($360), and a variable cost($2.5 per bowl). So the cost of each making b bowls is given by:
C(b) = 360 + 2.5b
Profit function:
She earns $5.5 for each bowl of soup she sells. So the earnings of selling b bowls are given by:
P(b) = 5.5b
How many bowls of soup would Bernadette need to sell to make money each month?
Bernadette will make money if the profit is higher than the cost, that is:
P(b) > C(b)
Then
5.5b > 360 + 2.5b
5.5b - 2.5b > 360
3b > 360
b > 360/3
b > 120
So, to make money each month, Bernadette would need to sell at least 121 bowls of soup.

Answers
The result of the equation 2(x-4)-9 = 3(2x+1)+4 is x= -6
The equation is
2(x-4)-9 = 3(2x+1)+4
The distributive property states that multiplying the sum of two or more variables by a number will produce the same result as multiplying each variables individually by the number and then adding the products together.
2(x-4)-9 = 3(2x+1)+4
Apply distributive property in the equation
2x-8-9 = 6x+3+4
Add the like terms in the equation
2x-17 = 6x+7
Rearrange the terms and combine the like terms in one terms
2x-6x = 7+17

For an algorithm bounded by a loop such as this one, due to the command while (i≤n), the length of the loop is bound of the complexity of the algorithm, hence we can begin the complexity equation as follows:

Inside the loop, for each iteration of the loop, that is, each value of i, two addition operations are made, adding i to t and incrementing the count control variable i by 1.

The regression equation y= - 0.434x+72.21 approximates the percent of people in an audience who finish watching a documentary, y, given the length of the film in minutes, x.
What percentage is the best prediction for the percent of people in an audience who will finish watching a documentary that is 27 minutes long? Round your answer to the hundredths place
Answers
Using the regression equation we can estimate that 60.49% of people will finish the documentary.
Regression analysis is a group of statistical procedures used in statistical modelling to determine the associations between a regression model and one or more relationship between the independent variable.
Y is the variable (the variable that is plotted on the Y axis), X is the independent variable (i.e., it is displayed on the X axis), b is the slope of the line, and an is the y-intercept.The equation has the form Y= a + bX.The equation is given as Y= - 0.434X+72.21
At X=27 , the value of Y can be estimated as :
Y = -0.434 × 27 +72.21
or, Y = 60.492
or, Y ≈ 60.49
Therefore 60.49 % is the best prediction of people will watch the documentary completely.

Please provide working out for a and b. Thanks.
Answers
a) 102 is the smallest of the dropdown number
b) 1025 is the smallest dropdown number
c) 9874 is the largest 4-digit dropdown number
Explanation:Given:
All digits in a dropdown number are different and one of its digits is the average of all its digits.
It has at least two digits.
To find:
a) the smallest dropdown number
b) the smallest and largest 4-digit dropdown numbers
a) From the information given, the numbers are at least two digits. This means the smallest of the digits from the dropdown is 2
We can't have 0 as the starting number because it will reduce the digits by 1. The list will start from the smallest to the highest since we are looking for the smallest number.
For two digits: 12, 13, 14, etc
We can only have a 2-digit number whose average is part of digits if the numbers are the same digit.
As a result, we will move to 3 digits.
For 3 dgits: 102, 103, 104, 105, etc
We will check if any of the above will have one of its digits as average
102: 1 + 0 + 2 = 3
Average = 3/3 = 1
One of the digits of this number is the average of the number.
Hence, 102 is the smallest of the dropdown number
b) To get the smallest 4 digit dropdown number, we will list from smallest to highest
For 4 digits: 1023, 1024, 1025, 1026, 1027, ...
We will check if any of the above will have one of its digits as average
1023: 1+0+2+3 = 6
Average = 6/4 = 1.5
1024: 1+0+2+4 = 7
Average = 7/4 = 1.75
1025: 1+0+2+5 = 8
Average = 8/4 = 2
One of the digits of this number is the average of the number.
Hence, 1025 is the smallest dropdown number
To get the largest 4-digit dropdown number, we will list from largest to smallest
For 4 digits: 9876, 9875, 9874, 9873, 9872, etc
We will check if any of the above will have one of its digits as average
9876: 9+8+7+6 = 30
Average = 30/4 = 7.5
9875: 9+8+7+5 = 29
Average = 29/4 = 7.25
9874: 9+8+7+4 = 28
Average = 28/4 = 7
One of the digits of this number is the average of the number.
Hence, 9874 is the largest 4-digit dropdown number

What is a formula for the nth term of the given sequence? Also how do I find it with further questions
Answers
option (D) aₙ = 300 (5 / 3)¹⁻ⁿ is a formula for the nth term of the given sequence.
The sequence given is:
300, 180, 108
The initial term = a = 300
We will first calculate the common ratio between the terms:
Common ratio = r
r = 180 / 300
r = 18 / 30
r = 3 / 5
Also,
108 / 180 = 3 / 5
Now, the formula for the nth term is given by:
aₙ = a rⁿ⁻¹
Substitute the values:
aₙ = 300 (3 / 5)ⁿ⁻¹
which can also be written as:
aₙ = 300 (5 / 3)¹⁻ⁿ
Therefore, we get that, option (D) aₙ = 300 (5 / 3)¹⁻ⁿ is a formula for the nth term of the given sequence.
