The equation of the line that goes through the point (3, 1) and is perpendicular to the line 2x + 4y = 5 can be written in the form y = mx + b where m= 2 and b= -5.

According to the question,

We have the following information:

Points = (3,1)

Equation of the line: 2x+4y = 5

Now, converting this line into y = mx+b form:

4y = -2x+5

y = -2y/4+5/4

y = -y/2+5/4

Now, the slope of this line is -1/2.

Slope of the line perpendicular to this line will be 2 (-1/m).

Now, the equation of the line will be:

(y-y') = m(x-x')

x' = 3 and y' = 1

y-1 = 2(x-3)

y-1 = 2x-6

y = 2x-6+1

y = 2x-5

The value of m is 2 and b is -5.

Hence, the equation of the line that goes through the point (3, 1) and is perpendicular to the line 2x + 4y = 5 can be written in the form y = mx + b where m= 2 and b= -5.

The exact interval notation of given equation is  x > - 8.

What is interval notation for compound inequalities?

The numbers that bound a continuous set of real numbers can be used to express the continuous set in interval notation. Intervals have many characteristics in common with ordered pairs when written.

We have,

            3x+1 > 2x-3 > x-11

Apply the rule that if m > v > n, then m > v and v > n to the given compound inequality to find the solution.

∴ m = 3x + 1,

   v = 2x - 3,

   n = x - 11.

Hence, by applying the rule of compound inequality we get,

          3x + 1 > 2x - 3 and 2x - 3 > x - 11

3x + 1 > 2x - 3

3x + 1 - 1 > 2x - 3 -1

3x > 2x - 4

3x - 2x > 2x - 4 - 2x

x > - 4

2x - 3 > x - 11

2x - 3 + 3 > x - 11 + 3

2x  > x - 8

2x  - x > x - 8 - x

x > - 8

The two computations above indicate that the acquired intervals, x > - 4 and x > - 8, will be combined to yield the answer to the given inequality.

Continuous compounding equation:

Now find the time t for the balance to grow to $51806.67:

The time required is about 9 years.

Answer:

9 years

Step-by-step explanation:

Continuous Compounding Formula

[tex]\large \text{$ \sf A=Pe^{rt} $}[/tex]

where:

Given values:

Substitute the given values into the formula and solve for r to find the annual interest rate:

[tex]\implies \sf 39786.15=36000 \cdot e^{2.5r}[/tex]

[tex]\implies \sf \dfrac{39786.15}{36000}= e^{2.5r}[/tex]

[tex]\implies \sf \ln \left(\dfrac{39786.15}{36000}\right)=\ln e^{2.5r}[/tex]

[tex]\implies \sf \ln \left(\dfrac{39786.15}{36000}\right)=2.5r[/tex]

[tex]\implies \sf \dfrac{1}{2.5}\ln \left(\dfrac{39786.15}{36000}\right)=r[/tex]

[tex]\implies \sf r=\dfrac{2}{5}\ln \left(\dfrac{39786.15}{36000}\right)[/tex]

[tex]\implies \sf r=0.03999996933...[/tex]

[tex]\implies \sf r=0.04\;(2\;d.p.)[/tex]

Therefore, the annual interest rate is 0.04 = 4%.

To calculate how many years it will take for $36,000 to grow to $51,806.67, substitute the values into the formula and solve for t:

[tex]\implies \sf 51806.67=36000 \cdot e^{0.04t}[/tex]

[tex]\implies \sf \dfrac{51806.67}{36000}= e^{0.04t}[/tex]

[tex]\implies \sf \ln\left(\dfrac{51806.67}{36000}\right)= \ln e^{0.04t}[/tex]

[tex]\implies \sf \ln\left(\dfrac{51806.67}{36000}\right)= 0.04t[/tex]

[tex]\implies \sf \dfrac{\ln\left(\dfrac{51806.67}{36000}\right)}{0.04}=t[/tex]

[tex]\implies \sf t=9.10 \; (2\;d.p.)[/tex]

Therefore, it will take about 9 years for $36,000 to grow to $51,806,67.

Using the distance formula, the distance between A to point Z to the nearest tenth is 4.1 .

The 2D distance formula gives the shortest distance between two points in a two-dimensional plane.

d = √(y₂ - y₁) + (x₂ - x₁)²

let's use the distance formula, to find the distance between point A and XZ.

Using the coordinates,

A(3, 3) and XZ(4, -1)

Therefore,

x₁ = 3

x₂ = 4

y₁ = 3

y₂ = -1

d = √(4 - 3)² + (-1 - 3)²

Answer: f(x) = x³ + 7x² -8x

Step-by-step explanation:

Zeros means that at that x-value, the graph crosses the x-axis and y = 0. Hence, to meet those criteria, the function would be:

[tex]f(x)=x(x+8)(x-1)[/tex]

At those three x-values, the corresponding y-values would equal 0.

Multiply them out to find the polynomial function:

[tex]f(x)=x(x+8)(x-1)=x(x^{2} -x+8x-8)=x^{3} +7x^{2} -8x[/tex]

By applying the distributive property of multiplication, this mathematical expression can be rewritten as -3(-4x + 5) = 12x - 15.

The distributive property of multiplication states that when the sum of two (2) or more addends are multiplied by a particular numerical value, the same result and output would be obtained as when each addend is multiplied respectively by the same numerical value, and the products are added together.

Mathematically, the distributive property of multiplication can be represented by this mathematical expression:

a(b + c) = ab + ac.

By applying the distributive property of multiplication to the given mathematical expression, we have the following:

-3(-4x + 5) = -3(-4x) + [-3(5)]

The probability of more than 5 people is 0.4729

Since 49% of the people in a community use the emergency room at a hospital in one year, a sample of 11 people use the emergency room. To find the probability of more than 5 people use the emergency room, we use binomial probability.

The binomial probability of x is given by  P(X = x) = ⁿCₓpˣ(1 - p)ⁿ⁻ˣ

where

Since

We determine the probability of x ≤ 5.

So, P(X ≤ 5) = ¹¹C₀p⁰(1 - p)¹¹⁻⁰ + ¹¹C₁p¹(1 - p)¹¹⁻¹ + ¹¹C₂p²(1 - p)¹¹⁻² + ¹¹C₃p³(1 - p)¹¹⁻³

So, P(X ≤ 5) = 0.5271, the probability of more than 5 people is P(X ≥ 5) = 1 - P(X ≤ 5)

Probability refers to possibility. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events. The degree to which something is likely to happen is basically what probability means. You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution. Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is.

c) P(green then blue) =  0.083 = 8.3%.

d) P(blue and red, any order) = 0.333 = 33.3%.

The probability of an event in an experiment is calculated as the number of desired outcomes in the context of the experiment divided by the number of total outcomes in the context of the experiment.

In this problem, the are nine marbles, of which four are red, hence the probability of both red is:

p = 4/9 x 3/8 = 0.167 = 16.7%.

(the marble is not replaced, hence for the second marble there will be eight possible marbles, of which 3 are red).

For red then green, the probability is:

p = 4/9 x 2/8 = 0.111 = 11.1%.

For green then blue, the probability is:

p = 2/9 x 3/8 = 0.083 = 8.3%.

For blue or red, there are two possible outcomes, blue then red or red then blue, hence:

The geometric sequence in which the 3rd term is of 18 and the 7th term is of 29/8 is defined as follows:

[tex]a_n = 40(0.67)^{n - 1}[/tex]

A geometric sequence is a sequence in which the result of the division of consecutive terms yields always the same result, called common ratio q.

The nth term of a geometric sequence is given by the rule presented as follows:

[tex]a_n = a_1q^{n-1}[/tex]

In which [tex]a_1[/tex] is the first term.

The rule for the nth term is also called the general rule.

The general takes the first term as the reference term, however, the 7th term can be written as a function of the 3rd term, as follows:

[tex]a_7 = a_3q^{4}[/tex]

The fraction that represents the mixed number 3 and 5/8 is:

(3 x 8 + 5)/8 = 29/8.

Then the common ratio of the sequence is calculated as follows:

[tex]\frac{29}{8} = 18q^{4}[/tex]

[tex]q^4 = \frac{29}{144}[/tex]

[tex]q = \sqrt[4]{\frac{29}{144}}[/tex]

[tex]q = \left(\frac{29}{144}\right)^{\frac{1}{4}}[/tex]

q = 0.67.

Then the first term of the sequence is obtained as follows:

[tex]a_3 = a_1q^2[/tex]

[tex]a_1 = \frac{a_3}{q^2}[/tex]

[tex]a_1 = \frac{18}{(0.67)^2}[/tex]

[tex]a_1 = 40[/tex]
