Irrational, Rational, and Complex Roots

Step-by-step explanation:

Irrational roots cannot be written as a fraction, for example, √2 is an irrational root because 2 is not a square number

Rational roots can be written as a fraction. For example, √4 is a rational root because it can be either -2 or 2 which are both rational.

Complex/imaginary roots take the form of [tex]a+bi[/tex] where "a" is the real part and "b" is the imaginary part. For example, √(-1) = i which is complex/imaginary.

Two triangles will be better than one half times five times thirteen. We'll also have a single rectangular piece. It measures 12 by 10. 20 times 2 equals 40. 13 divided by 2 divided by 2 is equal to 4. I am capable of 44 times two times two. 13 is 52 One is equal to 10 x 2 x 1/2. 12 times 10 is 120, and 5 times 13 is 65.

The required amount of sweets Steve will get is 42.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

here,
Ali and Steve share some sweets in a ratio of 2:7 Steve gets 30 more sweets than Ali.

Let the amount of sweet Ali and steve be x and y,
According to the question,
x / y = 2/7

x = 2y/7 - - - - (1)

And

y = 30 + x

From equation 1
y = 30 + 2y / 7
5y = 30 × 7
y = 42

Now,
x = 2 × 42 /7
x = 12

Thus, the required amount of sweets Steve will get is 42.

The mean of the distribution of sample proportions is 179.8 and the standard deviation is 0.019

The sample distribution of the proportions is used to measure the proportion with which success is achieved. The chance of an event taking place is the proportion computed by dividing the number of successes by the size of the sample.

Given that, You intend to draw a random sample of size n = 580 from a population whose parameter is p = 0.31, we are asked to find the mean of the distribution of sample proportions and standard deviation of the distribution of sample proportions.

Under the sampling distribution of the proportions, the mean and standard deviation are calculated by :

a) The mean is given as ;

μ = nP

Where, n is the sample size

P is the population proportion

Therefore,

μ = 580(0.31)

μ = 179.8

b) The standard deviation is given as follows :

δ = [tex]\sqrt{\frac{P(1-P)}{n} }[/tex]

δ = [tex]\sqrt{\frac{0.31(1-0.31)}{580} }[/tex]

δ = 0.019

Hence, the mean of the distribution of sample proportions is 179.8 and the standard deviation is 0.019

A rental car company charge $50 per day to rent a car and $0. 15 for every mile driven, then the inequality for the number of days will be represented as x ≤ 2.21 days.

It is referred to as being unfair when two terms are joined by a sign like "not equal to," "more than," or "less than." The inequality illustrates the relationship between variables and numbers in terms of greater than and less than.

In mathematics, a relationship between two expressions or values that are not equal to each other is called 'inequality'. So, a lack of balance results in inequality.

Given that a rental car company charges $50 per day to rent a car and $0.15 for every mile driven.

The equation of inequality will be written as,

C ≥ [tex]0.15m + 50x[/tex]    

Here, C is the total cost, m is the number of miles, and x is the number of days.

C ≥ [tex]0.15m + 50x[/tex]    

C ≥ ( [tex]0.15*100[/tex] ) + [tex]50x[/tex]

130 ≥ 19.5 + [tex]50x[/tex]

130 - 19.5 ≥ [tex]50x[/tex]

[tex]50x[/tex] ≤ 110.5

x ≤ 110.5 / 50

x ≤ 2.21 days

The perimeter of the rectangle, given that the rectangle has an area of 40 ft² and a length of 8 ft is 26 ft

We'll begin by obtaining the width of the rectangle. The width of the rectangle can be obtained as follow:

Area = Length × Width

40 = 8 × Width

Divide both sides by 8

Width = 40 / 8

Width = 5 ft

Finally, we shall determine the perimeter of the rectangle. Details below:

Perimeter = 2(Lenght + Width)

Perimeter = 2(8 + 5)

Bianca will earn interest of $382.5 for a period of 3years.

Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time. In simple interest, the principal amount is always the same.

Simple interest is calculated with the following formula:

S.I. = P × R × T,

where P = Principal, R = Rate of Interest in % per annum, and T = Time

Given,

Principal P = $3000

Rate of interest R = 4.25% = 4.25/100 = 0.0425

Time T = 3 years

Simple interest S.I. = P × R × T

                               = 3000 × 0.0425 × 3

                               = 127.5 × 3

                       S.I.   = $382.5

There is a concept known as an analogous expression, which is an expression that has the same value as another expression but has a different appearance.

Expressions that are equivalent do the same thing even when they have distinct appearances. When we enter the same value for the variable, two algebraic expressions that are equivalent have the same value.

To solve the problem, we must first find the slope of the line containing (4, -2) and (x, -6). The slope of a line is calculated as the change in y-coordinates divided by the change in x-coordinates, or (y2 - y1) / (x2 - x1). In this case, the slope of the line containing (4, -2) and (x, -6) is (-6 - (-2)) / (x - 4) = -4 / (x - 4)

Since the line containing (4, -2) and (x,-6) is perpendicular to the line containing (-2,-9) and (3,-4), we know that the product of the slopes of these two lines is -1. We can use that information to find the slope of the second line: -1 = (-4 / (x - 4)) * m, where m is the slope of the second line. Solving for m, we get m = -1 / (-4 / (x - 4)) = (x - 4) / 4.

We can now use the point-slope form of a linear equation to find the equation of the line containing (-2,-9) and (3,-4). The point-slope form is y - y1 = m(x - x1). In this case, we can use (-2,-9) as (x1, y1) and (x - 4) / 4 as m:

y - (-9) = (x - 4) / 4 * (x + 2)

Simplifying we get y = (x-4)/4 + (-9) = (x-4)/4 - 9

Now we can substitute x = -2 and y = -9 to check if it belongs to this line:

-9 = (-2 - 4)/4 - 9

-9 = -2/4 - 9

-9 = -0.5 - 9

-9 = -9.5

It match so this line is the correct one.

The value of x that satisfies the given conditions is x = -2

You can graph this line on a separate sheet of paper by plotting the point (-2, -9) and using the slope (x-4)/4 to find additional points on the line.

Sarah will make 6 baskets in her next 6 shots.

If Sarah made a basket on one of her first shots in a basketball game, and she continues to make baskets at the same rate, we can use that information to predict the number of baskets she will make in her next 6 shots.

Since we know that Sarah made a basket on one of her first shots, we can assume that the probability of her making a basket on any given shot is 1/1 or 100%.

If the probability of Sarah making a basket on any given shot is 100%, then we can expect her to make a basket on all 6 of her next shots. Therefore, Sarah will make 6 baskets in her next 6 shots.

In the exponential form, the exponent indicates the number of times the base is used as a factor.

For example, in the case of 16 it can be written as 2 × 2 × 2 × 2  = [tex]2^{4}[/tex], where 2 is the “base” and 4 is the “exponent.

A product in which the factors are identical is called a power of that factor.  The number that is repeated is called the base, and the number of times it repeats is called the exponent, power or degree.

A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, whereas B is a constant. A linear equation with two variables has the standard form Ax + By = C. Here, the variables x and y, the coefficients A and B, and the constant C are all present.

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

A linear equation is an algebraic equation in which each term has an exponent of 1, and which, when plotted on a graph, always yields a straight line. It is called a "linear equation" for this reason.
