The required polynomial in standard form with zeros –4, 0, 1, and 4 is x⁴- x³ - 16x²+16x
Polynomial functions are functions that have a leading variable of 3 and above.
Given the zeros of a polynomial as -4, 0, 1, and 4, their corresponding factors will be:
(x+4)), x-0, x-1 and x - 4
To get the polynomial function required, we will take the product of the factors as shown:
= x(x-1)(x+4)(x-4)
= (x²-x)(x²-4²) (Note that (x+4)(x-4) is from different of two square)
f(x)= x⁴-16x²-x³+16x
Rearranging
f(x) = x⁴- x³ - 16x²+16x
Hence the function x⁴- x³ - 16x²+16x gives the required polynomial in standard form.

The amount a tree grows in one month is directly proportional to the amount of water it is given. When a tree is giving 21 gallons of water it grows 8 cm that month. What is the constant of proportionality for this variation? record your answer to the nearest thousand.
Answer:
k = 0.381cm/gallon
Step-by-step explanation:
Let the amount a tree grows in one month be x
Let amount of water it is given be y
If the amount a tree grows in one month is directly proportional to the amount of water it is given, then;
x ∝ y
x = ky
k is the constant of proportionality
k = x/y
Given
x = 8cm
y = 21 gallons
k = 8/21
k = 0.381cm/gallon
A stainless steel patio heater is a square pyramid. The length of one side of the base is 23.6. in. The slant height of the pyramid is 90.9. in. What is the height of the pyramid?
Answer:
Step-by-step explanation:
The height of the heater is about 89.3 in.
You can solve this problem with the Pythagorean Theorem. The base is a square. So half way across the middle will the right under the tip of the pyramid. We can use the measurement with the slant height to write and solve the equation below.
23.8^2 + x^2 = 90.1^2
x will be about 89.3.

Each of students reported the number of movies they saw in the past year. Here is what they reported. 17,19,10,4,16,20
Answer:
14.3
Step-by-step explanation:
What you would do is add all 6 numbers together. After finding the sum, divide by 6. The 6 represents the amount of numbers in the data set. So you would find 86/6 and get 14.3333. That would be rounded to 14.3. Hope this helped!
Sam and Pam's pennies add up to 22. Same has 1 more penny than twice Pam's pennies. How many pennies do Sam and Pam have?
Answer:
pam has x = 7 pennies
sam has 2x + 1 = 14 + 1 = 15 pennies
Step-by-step explanation:
let's take the number of pennies that pam owns be x
sam's pennies = 2× ( pam's pennies ) + 1
=》2x + 1
if the total pennies owned by both = 22
then,
x + 2x +1 = 22
3x = 22 - 1
x = 21 ÷ 3
x = 7
so, pam has x = 7 pennies
sam has 2x + 1 = 14 + 1 = 15 pennies
the temperature fell 16 degrees fahrenheit from 50 to 34 degrees in 10 hours. How much would the temperature fall over 15 hours if the pattern continued?
Answer:
[tex]x = 24\ degrees[/tex]
Step-by-step explanation:
Given
16 degrees = 10 hours
Required
Determine the change over 16 hours
Let the change be represented with x,
So, we have:
16 degrees = 10 hours
x = 15 hours
Cross Multiply:
[tex]x * 10\ hours = 16\ degrees * 15\ hours[/tex]
[tex]x * 10 = 16\ degrees * 15[/tex]
Divide through by 10
[tex]x = \frac{16\ degrees * 15}{10}[/tex]
[tex]x = 16\ degrees * 1.5[/tex]
[tex]x = 24\ degrees[/tex]

A ball is taken from the bag at random, then replaced. A second ball is then selected at random. Find the probability that the first ball is red and the second ball is blue.
The probability that the first ball drawn is red and the second ball drawn is blue is 3/20.
The probability that the first ball drawn is red and the second ball drawn is blue, we need to multiply the probability of drawing a red ball on the first draw by the probability of drawing a blue ball on the second draw.
Given that there are 10 balls in total, with 5 red balls and 3 blue balls, the probability of drawing a red ball on the first draw is 5/10 = 1/2.
Since the ball is replaced after the first draw, the total number of balls remains the same for the second draw.
The probability of drawing a blue ball on the second draw is also 3/10.
To find the probability of both events occurring (the first ball being red and the second ball being blue), we multiply the probabilities:
Probability = (Probability of drawing a red ball) × (Probability of drawing a blue ball)
= (1/2) × (3/10)
= 3/20

To find:
The value of x.
Solution:
According to the geometric mean attitude theorem, if an altitude is drawn from the right angle vertex to the hypotenuse, then the altitude is the geometric mean of segments of hypotenuse.
Using geometric mean attitude theorem, we get
[tex]\dfrac{3}{x}=\dfrac{x}{5}[/tex]
[tex]3\times 5=x\times x[/tex]
[tex]15=x^2[/tex]
[tex]\pm \sqrt{15}=x[/tex]
But side cannot be negative. So,
[tex]\sqrt{15}=x[/tex]
Therefore, the value of x is [tex]\sqrt{15}[/tex].
State the domain and range of both the function and the inverse function. f(x) = 8 x + 8 f -1(x) = Domain of f(x): Range of f(x): Domain of f -1(x): Range of f -1(x)
Answer:
[tex]f^{-1}(x) = \frac{x+8}{8}[/tex]
Domain of f(x): All real values.
Range of f(x): All real values.
Domain of f -1(x): All real values.
Range of f -1(x): All real values
Step-by-step explanation:
We are given the following function:
[tex]f(x) = 8x + 8[/tex]
Since it is a line, we have that both the domain is the range is the real set.
Inverse function:
The domain of the inverse function is the range of the original function, and the range of the inverse function is the domain of the original function.
Finding the inverse function:
Exchange x and y in the original function, and isolate y. So
Original
[tex]y = 8x + 8[/tex]
Exchanging:
[tex]x = 8y - 8[/tex]
Isolating y:
[tex]8y = x + 8[/tex]
[tex]y = \frac{x+8}{8}[/tex]
[tex]f^{-1}(x) = \frac{x+8}{8}[/tex]

10a. This equation does not because 3/4 x 8 = 6 and not 9.
10b. This equation doesn’t because 3x8 does not equal 28.
10c. This equation does because 5 x 8 = 40 which means y = 8.
10d. This equation does because 8/2 = 4. Fractions are just division problems and 8 divided by 2 equals 4, meaning y = 8 was n this equation.

A total of 1,650 boxes of Girl Scout cookies were sold last week. Each large box cost $3.50 and each small box cost $2.00. The Girl Scout group
earned $4,650. How many large boxes and how many small boxes of cookies were sold?
Answer:
900 large boxes were sold, and 750 small boxes.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of large boxes of cookies sold.
y is the number of small boxes of cookies sold.
A total of 1,650 boxes of Girl Scout cookies were sold last week.
This means that
[tex]x + y = 1650[/tex]
So
[tex]x = 1650 - y[/tex]
Each large box cost $3.50 and each small box cost $2.00. The Girl Scout group earned $4,650.
This means that
[tex]3.5x + 2y = 4650[/tex]
Since [tex]x = 1650 - y[/tex]
[tex]3.5(1650 - y) + 2y = 4650[/tex]
[tex]5775 - 3.5y + 2y = 4650[/tex]
[tex]1.5y = 1125[/tex]
[tex]y = \frac{1125}{1.5}[/tex]
[tex]y = 750[/tex]
[tex]x = 1650 - y = 1650 - 750 = 900[/tex]
900 large boxes were sold, and 750 small boxes.
