For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cutoff point with the y axis

[tex]m = \frac {y2-y1} {x2-x1}[/tex]

According to the data we have two points through which the line passes, then we can find the slope:

[tex](x1, y1) = (0,3)\\(x2, y2) = (7,0)[/tex]

[tex]m = \frac {0-3} {7-0} = - \frac {3} {7}[/tex]

Then, the equation is given by:

[tex]y = - \frac {3} {7} x + b[/tex]

We substitute a point to find "b":

[tex]3 = - \frac {3} {7} (0) + b\\b = 3[/tex]

Finally, the equation is:

[tex]y = - \frac {3} {7} x + 3[/tex]

Answer:

[tex]y = - \frac {3} {7} x + 3[/tex]

Answer:

x = 16

y = 11

Step-by-step explanation:

Let the larger number = x

Let the smaller number = y

x  - y = 5

x = 2*y - 6

Put the second equation into the first. Substitute for x

2y - 6 - y = 5                          

combine

y - 6 = 5

and 6 to both sides.

y - 6 + 6 = 5 + 6

Combine

y = 11

=======================

Find x

x - y = 5           Substitute for y

x - 11  = 5          Add 11 to both sides.

x - 11+11=5+11

x = 16

Option C - Simplify the right side using the "difference of two logs is the log of the quotient" property.

Step-by-step explanation:

Given : Expression [tex]\ln (x-1)=\ln 6-\ln x[/tex]

To find : What is the first step in solving  the expression ?

Solution :

Expression [tex]\ln (x-1)=\ln 6-\ln x[/tex]

Step 1 - Simplify the right side using the "difference of two logs is the log of the quotient" property.

i.e. [tex]\ln a-\ln b=\ln(\frac{a}{b})[/tex]

Therefore, Option C is correct.

To determine the minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum of a data set, you need to follow these steps:

1. Order the Data Set: Arrange the data set in ascending order.

2. Minimum and Maximum: Identify the smallest and largest values in the ordered data set.

3. Median (Q2): This is the middle value of the data set. If there is an odd number of observations, it is the middle one. If there is an even number of observations, it is the average of the two middle values.

4. First Quartile (Q1): This is the median of the first half of the data (the lower 50%). If the number of observations is odd, do not include the median in this half.

5. Third Quartile (Q3): This is the median of the second half of the data (the upper 50%). If the number of observations is odd, do not include the median in this half.

Let's consider an example data set to illustrate these steps:

Example Data Set: 3, 7, 8, 5, 12, 14, 21, 13, 18

1. Order the Data Set: 3, 5, 7, 8, 12, 13, 14, 18, 21

2. Minimum and Maximum:

  - Minimum = 3

  - Maximum = 21

3. Median (Q2):

  - Since there are 9 data points (odd number), the median is the 5th value.

  - Median = 12

4. First Quartile (Q1):

  - The lower half of the data (excluding the median) is: 3, 5, 7, 8

  - Median of this lower half = (5 + 7) / 2 = 6

5. Third Quartile (Q3):

  - The upper half of the data (excluding the median) is: 13, 14, 18, 21

  - Median of this upper half = (14 + 18) / 2 = 16

So, the five-number summary for the example data set is:

- Minimum = 3

- First Quartile (Q1) = 6

- Median (Q2) = 12

- Third Quartile (Q3) = 16

- Maximum = 21

Answer:

The solution set is { (3, 4), (5 , 0) }.

Step-by-step explanation:

x^2 + y^2= 25

2x   +   y =  10

We use substitution:

From the second equation y = 10 - 2x.

Substituting for y in the first equation:

x^2 + (10 -2x)^2 = 25

x^2 + 100 - 40x + 4x^2 - 25 = 0

5x^2 - 40x  + 75 = 0

Divide through by 5:

x^2 - 8x + 15 = 0

(x - 3)(x - 5) = 0

x = 3, 5.

when x = 3 , y = 10 - 2(3) = 4.

when x = 5, y = 10 - 2(5) = 0.

Answer:

(3,4) (5,0)

Step-by-step explanation:

The answer is:

In 2036 there will be a population of 32309 rabbits.

We can calculate the exponential decay using the following function:

[tex]P(t)=StartAmount*(1-\frac{percent}{100})^{t}[/tex]

Where,

Start Amount, is the starting value or amount.

Percent, is the decay rate.

t, is the time elapsed.

We are given:

[tex]StartAmount=144,000\\x=7.2(percent)\\t=2036-2016=20years[/tex]

Now, substituting it into the equation, we have:

[tex]P(t)=StartAmount(1-\frac{percent}{100})^{t}[/tex]

[tex]P(t)=144000*(1-\frac{7.2}{100})^{20}[/tex]

[tex]P(t)=144000*(1-0.072)^{20}[/tex]

[tex]P(t)=144000*(0.928)^{20}[/tex]

[tex]P(t)=144000*(0.928)^{20}[/tex]

[tex]P(t)=144000*0.861=32308.888=32309[/tex]

Hence, we have that in 2036 the population of rabbis will be 32309 rabbits.

Have a nice day!

The population of rabbits in 2036 is 32309 and this can be determined by using the exponential decay function.

Given :

The formula for the exponential decay function is given by:

[tex]\rm A = P(1-\dfrac{r}{100})^t[/tex]

Now, substitute the value of known terms in the above formula.

[tex]\rm A = 144000(1-\dfrac{7.2}{100})^{20}[/tex]

Simplify the above expression.

[tex]\rm A = 144000\times (0.928)^{20}[/tex]

[tex]\rm A = 32308.888[/tex]

A [tex]\approx[/tex] 32309

So, the population of rabbits in 2036 is 32309.

Answer:

4.3

Step-by-step explanation:

Answer:  26.67%

Step-by-step explanation:

32 touchdowns divided by 12 interceptions

32/12 = 26.66666%

26.66666 rounds up to 26.67%

Final answer:

The simplified ratio of touchdowns to interceptions that Max threw is 8:3, found by dividing both the number of touchdowns (32) and interceptions (12) by their greatest common divisor, which is 4.

Explanation:

To find the most simplified form of the ratio of touchdowns to interceptions that Max threw, we divide the number of touchdowns by the number of interceptions. Max threw 32 touchdowns and 12 interceptions. To simplify this ratio, we need to find the greatest common divisor (GCD) that both numbers share. In this case, the GCD of 32 and 12 is 4.

Dividing both numbers by the GCD, we get: 32 ÷ 4 = 8 and 12 ÷ 4 = 3. Therefore, the simplified ratio of touchdowns to interceptions is 8:3.

(-2,4] and [7,∞).

The second choice is correct:

Answer:

(-2,4] and [7, infinity)

Step-by-step explanation:

Answer:

Dividing two binomials will not always result in a polynomial. For instance, divide (x+2) over (x+3) and we won't get a polynomial. The result is known to be a rational expression but not a polynomial. So that's why division is not closed for polynomials.

Contrast that with addition, subtraction and multiplication. For any of those operations taking two polynomials and adding them, subtracting them, or multiplying them will lead to another polynomial. That's why these operations are closed for polynomials.

Step-by-step explanation:

Since we know the length and width cannot both be 12 (to make 144), other factors of 12 can be tested to be a product of 144. Half of 12 is 6, and 24 * 6 = 144. If we add up 12 + 12 + 6 + 6, we get 60, or the given perimeter.

The length and width of the rectangle, set up and solve a system of equations based on the given area and perimeter. By factoring the quadratic equation obtained from the area and perimeter formulas, it is determined that the rectangle's width is 12 inches and its length is 18 inches.

The length and width of a rectangle with an area of 144 square inches and a perimeter of 60 inches, we can set up a system of equations using the formulas for area and perimeter of a rectangle, which are Area = length  imes width and Perimeter = 2  imes (length + width), respectively. Let the length be represented by 'l' and the width by 'w'.

Step 1: Set up the equations

Area = l  times w = 144
Perimeter = 2l + 2w = 60

Step 2: Solve the system of equations

First, simplify the perimeter equation to get l + w = 30. Then, express l in terms of w: l = 30 - w. Now substitute l in the area equation: (30 - w)w = 144.

Step 3: Solve the quadratic equation

Expand the equation: 30w - w² = 144.
Rearrange to form: w²- 30w + 144 = 0.
Factoring the quadratic equation gives: (w - 12)(w - 18) = 0.

Step 4: Find w and l

Setting each factor equal to zero gives us two possible widths: w = 12 or w = 18. If w = 12, then l = 30 - w = 18. If w = 18, then l = 30 - w = 12. Since both options give us the same pair of numbers, and a rectangle's sides can be switched without changing its shape, the rectangle's width is 12 inches and its length is 18 inches, or vice versa.

Let D = difference between mean and median of data.

Mean = (22 + 8 + 10 + 18 + 12 + 20)/6

Mean = 90/6

Mean = 15

Let m = median

m = 8, 10, 12, 18, 20, 22

m = (12 + 18)/2

m = 30/2

m = 15

D = M - m

D = 15n- 15

D = 0

we can simplify it to this:

[tex]y = - 2 {x}^{2} - 12x - 16 [/tex]

so we know it , the intercept in a standard equation of a parabola is C:

[tex]a {x}^{2} + bx + c[/tex]

so the intercept is (-16) and for the vertex use:

x=-b/2a

[tex]x = \frac{12}{ - 4} = - 3 [/tex]

so now put it in the equation and get the y of vertex:

y=-18+36-16=2 ==>vertex(-3,2)

Final answer:

The vertex of the function y=-2(x+3)²+2 is (-3, 2). The y-intercept is at (0, -16).

Explanation:

To identify the vertex and the y-intercept of the graph of the function y=-2(x+3)2 +2, we need to understand the structure of a quadratic function in vertex form, which is y=a(x-h)2+k, where (h, k) is the vertex of the parabola and a determines the direction and width of the parabola.

For the given function, the vertex can be found by looking at the values inside the parentheses and the constant term outside. In this case, the vertex is at x = -3 and y = 2, so the vertex is (-3, 2). The y-intercept occurs where x = 0. Substituting x = 0 into the function, we get y = -2(0+3)2+2 = -2(9)+2 = -18+2 = -16. Therefore, the y-intercept is at (0, -16).

TLDR: The answer is -2.

What you have here is a function with a point on the graph. It is understood that “x” represents the input and “y” represents the output, so we’re looking for the right “x” that will give y = 1/100.

To start, we can substitute the y-value into the function like this:

y = 10^x

1/100 = 10^x

From here, we can take two different pathways; one requires conceptual knowledge while the other relies on the knowledge of logarithms.

Conceptual

For the conceptual, we know that 100 = 10^2, so 1/100 is the same as 1/10^2. We also know that the inverse of a fraction is the same as the number to the negative of its power (for example, 1/2 is equal to 2^-1), so we know that 1/10^2 is the same as 10^-2. So far, we have learned that:

1/100 = 10^x

1/10^2 = 10^x

10^-2 = 10^x

So, to satisfy this, “x” must equal -2.

Logarithms

For logarithms, we can use powers and math to actually calculate the value of “x”. We know that:

1/100 = 10^x

To solve this, we need “x” to be by itself on one side of the equation. To do this, we can perform the inverse function of an exponent, which is a logarithm. In this case, the base of 10^x is 10, so we need a “base 10” logarithm to solve this function. Apply this function to both sides and simplify:

1/100 = 10^x

log10(1/100) = log10(10^x)

log10(1/100) = x

The log10 function is the inverse of 10^x, so they cancel out to leave “x”. Plug log10(1/100) into a calculator, and you find that x = -2.

Hope this helps!
