write a polynomial function of least degree with integral coefficients that has the given zeros. -1, 3+3i

Answers

The least degree polynomial function with integral coefficients and the given zeros, -1, 3+3i is f(x) = x³ + x².

What do we mean by polynomial function?A polynomial function is one that involves only non-negative integer powers or positive integer exponents of a variable in an equation such as the quadratic equation, cubic equation, and so on. For example, 2x+5 is a polynomial with an exponent of one.

So, given zeroes are -1, 3+3i.

We got: x = -1Then, x + 1 = 0.Hence, one factor of the polynomial function is (x+1).

Similarly,

We have: 3+3iRewrite as: x = 3 + √-9Square both the sides: x² = 9 - 9So, the other factor is x².

So, the polynomial has the function: (x+1)x²

(x+1)x²x³ + x²f(x) = x³ + x²

Therefore, the least degree polynomial function with integral coefficients and the given zeros, -1, 3+3i is f(x) = x³ + x².

'DesTunes is a new music streaming service.
Write an equation to represent each scenario, where x represents the number of months and y represents the total charge.
Scenario 1: DesTunes charges adults $15 per month.

Answers

The equation that represent scenario 1 is y = 15x while the equation that represent scenario 2 is y = 5x + 20

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represents the number of months and y represents the total charge.

Scenario 1: DesTunes charges adults $15 per month.

Hence:

y = 15x

Scenario 2: DesTunes charges students a $20 sign-up fee and $5 per month, hence;

y = 5x + 20

A water molecule has a mass

of 3 x 10-29 kg. A bottle

contains 1.7x 1028 molecules of water. Calculate the mass

of water in the bottle.

Answers

Answer:       5.1 x 10⁻¹ kg

To find the mass of water in the bottle, we can multiply the mass of one molecule by the number of molecules.

Dimensional Analysis

By using dimensional analysis, or by cancelling out units, we can figure out what to multiply or divide. Dimensional analysis uses fractions written with units. Dividing the same unit cancels out units we don't need.

To solve:

Figure out what units we need in the answer.Write the fractions using given information from the question.Put the fractions in an equation.Cancel out units to solve.

Units we need in the answer

We are looking for the mass of H₂O in the bottle.

The units we need in the answer are:      [tex]\displaystyle{ \frac{kg}{bottle} }[/tex]

Write fractions with given information

The question tells us:

the mass of one H₂O molecule is 3 x 10⁻²⁹ kg:   [tex]\displaystyle{ \frac{(3 * 10^{-29}\ kg)}{1\ H_{2}O}}[/tex]the bottle has 1.7 x 10²⁸ molecules of H₂O:    [tex]\displaystyle{ \frac{(1.7*10^{28}\ H_{2}O)}{1\ bottle}}[/tex]

Write an equation

Our equation puts the fractions in an equation, making them multiply to get the units we need.

[tex]\displaystyle{ \frac{(3 * 10^{-29}\ kg)}{1\ H_{2}O} \ *\ \frac{(1.7*10^{28}\ H_{2}O)}{1\ bottle}}\ =\ \frac{kg}{bottle}[/tex]

Why is this equation correct?

Remember that dividing the same unit will cancel them out. In the equation, we have H₂O in a numerator and H₂O in a denominator. So, H₂O will cancel out. In the end, we will only have kg in the numerator and bottle in the denominator.

Cancel out units to solve

Take the equation we wrote. Now that we know our equation gives us the right units, we only need the front part.

[tex]\displaystyle{ \frac{(3 * 10^{-29}\ kg)}{1\ H_{2}O} \ *\ \frac{(1.7*10^{28}\ H_{2}O)}{1\ bottle}}[/tex]

Cancel out H₂O:

[tex]=\displaystyle{ \frac{(3 * 10^{-29}\ kg)}{1} \ *\ \frac{(1.7*10^{28})}{1\ bottle}}[/tex]

Simplify the equation:

[tex]=\displaystyle{ \frac{(3 * 10^{-29})*(1.7*10^{28})\ kg}{1\ bottle}[/tex]

[tex]=\displaystyle{ \frac{3 * 10^{-29}*1.7*10^{28}\ kg}{1\ bottle}[/tex]

Use exponent rules to multiply 10⁻²⁹ with 10²⁸:

[tex]=\displaystyle{ \frac{3 *1.7*10^{28-29}\ kg}{1\ bottle}[/tex]

[tex]=\displaystyle{ \frac{3*1.7*10^{-1}\ kg}{1\ bottle}[/tex]

Multiply within the numerator to simplify:

[tex]=\displaystyle{ \frac{5.1*10^{-1}\ kg}{1\ bottle}[/tex]

∴ The mass of water in the bottle is 5.1 x 10⁻¹ kg.

The container that holds the water for the football team is 2/5 full. After pouring in 6 gallons of water, it’s 7/10 full. How many gallons can the container hold

Answers

Answer:

20

Step-by-step explanation:

We need to determine what fraction of the container 6 gallons is. We know the difference between 2/5 and 7/10 is 6 gallons, so all we have to do is solve for 7/10 - 2/5. The common denominator is 10, as both 5 and 10 are factors of 10. 10/5 is 2, so we multiply the numerator of 2/5 by 2.

7/10 - 4/10 = 3/10

We now know that 6 gallons is 3/10 of the container. Now we solve.

10/3 = 3 1/3

So:

6 x 3 1/3 = 20

Answer:

20 gallons.-

Step-by-step explanation:

Let x be the number of gallons that the container holds.

The we have the equation

2/5 x + 6 = 7/10 x

Multiply through be 10

4x + 60 = 7x

3x = 60

x = 20.

However, confounding factors could include the number of new buildings constructed in 2013, which was not factored in by the architectural company and the state of the economy in 2013.

You measure a foam roller in the shape of a cylinder. The foam roller has a diameter of 5.9375 inches and a height of 53.5 inches. About how many cubic inches of foam were used to make the roller?

Answers

Answer:

Volume V ≈ 1481.3269 cubic inches

Step-by-step explanation:

Volume V of a cylinder is given by the formula

V = πr²h  where r = radius of the base of the cylinder and h the height

Here we are given the diameter, d = 5.9375 inches

Radius r = d/2 = 5.9375/2 = 2.96875 in

Height h = 53.5 in

V = π x 2.9685² x 53.5 ≈ 1481.3269 cubic inches

Answers

The claim made by Morehouse college make more sense as their ratio of winning a game than losing it is higher.

a) In home games, the Spelman college won 10 wins whereas Morehouse College won only 9 games.

So, Spelman College has a better team than Morehouse College in home games.

b ) In Away games, Morehouse College won 56 games whereas Spelman College only won 12 games. So, Morehouse College has a better team than Spelman College in Away games.

c ) In total, Spelman College has won 22 games and lost 23 games. The ratio of win is to lose is 22 : 23 that is it won 0.96 games against it lost 1 game. In total, Morehouse College won 65 games and lost 39 games. The ratio of win it to lose is 65 : 39 that is it won 1.67 games against the 1 game it lost.

The option yes, d = -2 is correct

The arithmetic sequence or progression is a sequence of numbers such that the difference between the consecutive terms is constant.

The formula of an arithmetic sequence is

           [tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n-1)d

Here the sequence is 18, 16, 14, 12, 10...... which is in arithmetic sequence as there is a common difference between them.

Now we have to find the common difference between the two consecutive terms of the series,

common difference (d) = 16- 18 = 14 - 16 = -2

Therefore the series is an arithmetic sequence and the common difference between them is -2.

The difference of the squares of two positive consecutive even integers is 84. Find the integers. Use the fact​ that, if x represents an even​ integer, then x + 2 represents the next consecutive even integer.

Answers

Answer:

The integers are 20 and 22

Step-by-step explanation:

Let the first even integer be x . Then the next consecutive even integer
= x  + 2
The relationship between these two integers is the difference of the squares = 84

This means
(x + 2)² - x² = 84

Use the relationship a² - b² = (a + b) (a -b)

Here a = x + 2 and b = x

So

a + b = (x + 2 ) + x = x + 2 + x = x + x + 2 = 2x + 2
a  - b = (x + 2) - x = x + 2 - x = x -x + 2 = 2

Therefore

(a + b)(a - b) in terms of x is
(2x + 2) x 2 = 4x + 4

We know this is 84

So 4x + 4 = 84

Subtract 4 on both sides:
4x = 84 -4

4x = 80

x = 20

So the next consecutive even integer = 22

The integers are 20 and 22

[(5 · n - 1) / (n + 1)] · (n / n)

[(5 · n - 1) / n] / [(n + 1) / n]

(5 - 1 / n) / (1 + 1 / n)

Answers

Using linear functions, it is found that 4 movies would cause the two plans to have an equal monthly cost.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

For the functions in this problem, we have that:

The fixed cost is the intercept.The cost per movie is the slope.

Hence the cost functions are given as follows:

C1(x) = 22 + x.C2(x) = 14 + 3x.

The costs will be the same when:

C1(x) = C2(x).

Hence:

22 + x = 14 + 3x

2x = 8

x = 4.
