if you had only 5 and 11 cent stamps. whats the smallest number that would be impossible to make with those stamps.
If you had only 5 and 11 cent stamps, it would be impossible to make a postage stamp for any amount less than 16 cents.
This is because 16 cents is the smallest amount that can be made with those two denominations of stamps.
To prove this, let's start by looking at the possible combinations of 5 and 11 cent stamps that can be used to make a postage stamp:
5 cent stamps x 11 cent stamps
1 x 0 = 0
1 x 1 = 11
2 x 0 = 10
2 x 1 = 16
As you can see, the smallest possible combination of 5 and 11 cent stamps is 2 five cent stamps and 1 eleven cent stamp, which totals 16 cents. Therefore, it is impossible to make a postage stamp for any amount less than 16 cents using only 5 and 11 cent stamps.

neil uses 41-cent stamps and 8-cent stamps to mail a gift card to a friend. if the postage is $1.95, how many of each stamp did neil use?
If Neil uses 41-cent stamps and 6-cent stamps to mail a gift card to a friend , then the number of 41 cent stamp used is 3 and number of 6 cent stamps used is 12 .
Let number of 41 cents stamps used be = x ;
and let number of 6 cents stamps used be = y ;
converting amount 41-cents in dollars is = $0.41 ;
and converting amount 6-cents in dollars is = $0.06 ;
the amount for which Neil used 41-cent stamps , 6-cent stamps is = $1.95 ;
this situation in equation form is written as ⇒ 0.41x + 0.06y = 1.95
Multiplying on both sides by 100 , we get
⇒ 41x + 6y = 195 ;
⇒ y = (195 - 41x)/6 ;
We will test this equations for values of x and y , the number of stamps must be whole numbers .
If x = 1 , then value of y is = 25.66
If x = 2 , then value of y is = 18.833
If x = 3 , then value of y is = 12
If x = 4 , then value of y is = 5.166 .
the only value of x and y which shows a whole number as an output is : If x = 3 , then y = 12 .
Therefore , Neil used "3" 41-cents stamps and "12" 6-cent stamps .

What are all values of x for which the graph of y = x^4 - 6x^2 + x is concave downward? Show your work and justify your answer.
Answer:
A function is concave downward if its second derivative is negative. To find the values of x for which the graph of y = x^4 - 6x^2 + x is concave downward, we need to find the values of x for which the second derivative of y is negative.
The second derivative of y = x^4 - 6x^2 + x is y'' = 12x^2 - 12x
To find the values of x for which y'' is negative, we need to find the roots of the equation 12x^2 - 12x = 0.
We can factor the equation as: 12x(x-1) = 0
which gives us x = 0 and x = 1 as the roots.
Now, we need to test the sign of the second derivative in the intervals between the roots.
In the interval (0,1)
y'' = 12x^2 - 12x is positive, therefore the function is not concave downward in this interval.
In the interval (-infinity,0)
y'' = 12x^2 - 12x is negative, therefore the function is concave downward in this interval.
In the interval (1,infinity)
y'' = 12x^2 - 12x is negative, therefore the function is concave downward in this interval.
Therefore, the values of x for which the graph of y = x^4 - 6x^2 + x is concave downward are all values of x less than 0 or greater than 1.
what single transformation will you have to apply to this parabola to make it fit the inside curve of the banana? answer
The shape of the banana curve is a parabola, the number of zeros is 1, the zeros of the polynomial are (-3, 4), and the quadratic polynomial is a(x² - 16).
(i) The shape of the banana curve from the figure is a parabolic shape.
(ii) The number of zeros of the polynomial for the shape of the banana is 1.
(iii) To find the zeroes of f(x) = x² - x - 12, we need to solve the equation x² - x - 12 = 0 using the quadratic formula.
x = (-b ± √(b² - 4ac)) / 2a, where a = 1, b = -1, c = -12
x = (1 ± √(1 + 48)) / 2
x = (1 ± √49) / 2
So, the zeroes are (1 + 7) / 2 = 4 and (1 - 7) / 2 = -3.
(iv) If the representation of the banana curve whose one zero is 4 and the sum of the zeroes is 0, then the equation is x = -4 and x = 4.
The quadratic polynomial is f(x) = a(x - 4)(x + 4) = a(x² - 16).
Since the coefficient a is not given, we cannot determine the exact polynomial, but we know it must be of form f(x) = a(x² - 16).

What is an arithmetic sequence?It is a series of numbers that increase or decrease by a constant amount called the ratio of the progression. It is increasing when the ratio is positive and decreasing when it is negative.
To solve this exercise we are going to apply the formula of the arithmetic sequence:
S = (n/2)[a1 + a1 + d(n - 1)]
Where;
n= number of termsa1= first terma1 + d(n - 1) = last termd = common difference between termsInformation about the problem:
a1 = 7d = 5S = 5000Clearing the (n) variable we get:
S = (n/2)[ 7 + 7 + 5(n-1) ] > 5000
(n/2) [ 9 + 5n ] > 5000
n[ 9 + 5n ] > 10000
5n^2 + 9n - 10000 > 0
Solving the quadratic question we get the values for the (x) number
x= {- b ± √ [b² - (4* a*c)]} / (2 *a)
x= {- 9 ± √ [9² - (4* 5*-10000)]} / (2 * 5)
x= {- 9 ± √ (81+ 200000)} / 10
x= {- 9 ± √200081} / 10
x= (- 9 ± 447.30) / 10
x = 43.83
n > 43 then n = 44
Calculating the 44th term, we get:
aₙ= a + d*(n-1)
a44 = [ 7 +5(44 - 1) ]
a44 = [ 7 +5(43) ]
a44 = 222

y=-x² - 7x - 10
Using the factor method, the other x-intercept for the parabola defined by the equation is; (-5, 0)
How to find the x-intercept of a parabola?We are given the equation of the parabola as;
y = -x² - 7x - 10
We are given one of the x-intercepts as (-2, 0). Thus, let us factorize the equation of the parabola by setting it to zero to get;
-x² - 7x - 10 = 0
Let's factor it as;
-x² - 2x - 5x - 10
Factorizing it out gives;
-x(x + 2) - 5(x + 2) = 0

In how many ways can four people with different heights line up single-file so that exactly two people are taller than the person immediately behind them?
Are 5 ways for four people with different heights to line up single-file so that exactly two people are taller than the person immediately behind them.
What is Principle of Inclusion-Exclusion?Let's call the four people A, B, C, and D, and let's assume that their heights are distinct and that A is the shortest. Then, there are 3! = 6 ways for them to line up single-file without any restrictions on their heights. However, this counts the cases where A is taller than B, which is not allowed.
To correct for this overcounting, we can subtract the number of ways where A is taller than B, which is 2! = 2, since there are 2! ways to arrange B, C, and D in this case.
However, this also subtracts the case where A is taller than both B and C, which is not allowed.
So, we need to add the number of ways where A is taller than both B and C, which is 1, since there is only 1 way to arrange B, C, and D in this case. Therefore, by PIE, the number of ways for A, B, C, and D to line up single-file so that exactly two people are taller than the person immediately behind them is:
6 - 2 + 1 = 5
So, there are 5 ways for four people with different heights to line up single-file so that exactly two people are taller than the person immediately behind them.

feet
As per the perimeter of rectangle, the the amount area of fence does she need to buy to build around her new garden is 40 feet.
In math the term called perimeter is defined as the length of the outline of a shape. And the general form to calculate the perimeter of the rectangle is written as,
=> P = 2(l + b)
here l refers the length of rectangle and b refers the breadth of rectangle.
Here we know that the gardens old measurements is written as,
=> length = 14 feet
=> breadth = 16 feet.
Then the perimeter of garden is calculated as,
=> P1 = 2(14 + 16)
=> P1 = 2(30)
=> P1 = 60
Then the new measurement is given that,
length = 28 feet
width = 12 feet.
Then the new measurement is calculated as,
=> P2 = 2(28 + 12)
=> P2 = 2(40)
=> P2 = 80
Then additional fence does she need to buy to build around her new garden is

Identify the simplest polynomial function having integer coefficients with the given zeros.
4i, 3, −1
The simplest polynomial function having integer coefficients with the given zeros is: x⁴ -2x³ + 14x² - 32x - 48
How to solve for the polynomialThe polynomial is of degree 4
We have the values as 4i, 3 , -1
Hence we would have the following in brackets
for 4i = (x - 4i) (x + 4i)
for 3 = (x - 3)
for - 1 = (x + 1)
We would have to multiply these
(x - 4i) (x + 4i) (x - 3) (x + 1)
f(x) = x² + 4ix - 4ix (-4i)² (x² + x - 3x - 3)
f(x) = (x² + 16)(x² - 2x - 3)
This can also be expanded to standard form if you wish
x⁴ - 2x³ - 3x² + 16x² - 32x - 48
properly arrange
x⁴ -2x³ + 14x² - 32x - 48

at the city museum, child admission is $6.50 and adult admission is $9.60. on tuesday, four times as many adult tickets as child tickets were sold, for a total sales of $1436.80. how many child tickets were sold that day
A total of 31 child tickets were sold that day.
System of Equations:
Problems with two unknown values require a system of equations containing two variables.
A unique solution is obtained only when the lines formed by the equations intersect at only one point.
Let C be the number of child tickets and A be the number of Adult tickets
Now, like most coin, cost, or earnings problems, you can make a number balance and a money balance and get two equations for the two unknowns defined above:
4C=adults, because four times as many tickets were sold
6.50C+9.80(4C)=1436.80
6.50C+39.2C=652.50
45.7C=1436.80
C=31

y=x^2+6x+8 solve by factoring.
Answer:
To factor the equation y = x^2 + 6x + 8, we can use the method of finding the factors of the constant term (8) that add up to the coefficient of the x term (6).
In this case, the factors of 8 are 1 and 8, and -1 and -8. But only -1 and -8 add up to 6, so we can factor the equation as:
(x + 8)(x + 1) = 0
So the solutions are x = -8 and x = -1.
