Answer:

Slope = -4

Step-by-step explanation:

Given:

Rate of change (Slope) formula:

[tex]\text{Slope} = \dfrac{\text{Rise}}{\text{Run}} = \dfrac{\text{y}_{2} - \text{y}_{1}}{\text{x}_{2} - \text{x}_{1} }[/tex]

Where:

Substitute the coordinates of the given points in the formula to determine the slope of the line (Rate of change).

[tex]\implies \text{Slope} = \dfrac{(-18) - (-10)}{8 - 6 }[/tex]

Finally, let's simplify the fraction on the right hand side as needed.

[tex]\implies\text{Slope} = \dfrac{(-18) + 10}{8 - 6 }[/tex]

[tex]\implies \text{Slope} = \dfrac{-8}{2 } = -4[/tex]

Therefore, the slope of a line that passes through (6 , -10 ) and (8, -18) is -4.

The function that represents the total cost, c(x), of this kayak tour package for x club members is 245 + 35x

According to the given question, we have the following parameters

Amount charged on tour guide = $245

Let the total number of club members charged be "x", such that if the company charges $35 per person, the total cost on "x" members will be 35x

Total cost =  Amount charged on tour guide + cost of "x" members

Total cost = 245 + 35x

Hence the function that represents the total cost, c(x), of this kayak tour package for x club members is 245 + 35x

Median = 58.5

Q1 = 55

Q3 = 65

Interquartile = 10

Step-by-step explanation:

first let’s correct the data set :

It’s 38 46 55 56 58 59 61 65 67 75  not   38 46 55 56 558 59 61 65 67 75

Data set : 38 46 55 56 58 59 61 65 67 75

Median:

After we put Our data set from Smallest to largest

we define the median as the middle number of the data set but our set consists of an even number which is 10

In this case the median is the average of the two middle numbers which are the 5th and 6th numbers

38 46 55 56 [58 59] 61 65 67 75

Then

Median = (58+59)/2 = 117/2 = 58.5

quartile 1 : It’s just the median of the lower set of numbers which means it’s the median of : 38 46 55 56 58

Then Q1 = 55 because it’s the middle number.

quartile 3 : It’s just the median of the upper set of numbers which means it’s the median of : 59 61 65 67 75

Then Q3 = 65  (Easy to spot)

Interquartile = Q3 - Q1 = 65 - 55 = 10

An equation is formed of two equal expressions. Janes should multiply both sides of the equation by (y²-1).

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The equation that is given is an equation with a mixed fraction, therefore, the denominator with the highest power should be multiplied on both sides of the equation. The equation that is given to us

[tex]y + \dfrac{y^2-5}{y^2-1} = \dfrac{y^2+y+2}{y+1}[/tex]

As we can see in the equation that there are 2 denominators, which are,

In the two of the expressions that are stated above the expression (y²-1) is of a higher power.

FOR CONNEXUS UNIT 3 LESSON 1 SOLVING SYSTEMS BY GRAPHING 1. C 2. A 3. A 4. A

Step-by-step explanation:

Answer:

y=e^x - 4

Step-by-step explanation:

The log functions decrease with increasing x.  The line shown increases as x increases, so it must be one of the two e^x equations.  We can decide which one by calculating which equation povides the correct values to match the two points the curve crosses the y and x axes.

The graph shows the line crossing the y axis at -3 (0,-3)

It shows it crossing the x axis at a little over 1, perhaps 1.4 (1.4,0).  

When x=0, e^0 = 1.  

Look at the point (0,-3):  

We know the e term will be 1 (e^0 = 1), so for y to be -3, we need to subtract 4:  The form e^x - 4  would yield a value for y, when x is 0, of y = 1 - 4 or -3.

Check the other point (1.4,0):

y = e^1.4  is equal to 4.00

y = 4.00 - 4

y = 0

This point is also correct (1.4,0)

The correct equation is y=e^x - 4

Answer:

b = 10 ft , h = 6 ft

Step-by-step explanation:

the area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

let base = b theh height h = b - 4

given A = 30 , then

[tex]\frac{1}{2}[/tex] b(b - 4) = 30 ( multiply both sides by 2 to clear the fraction )

b(b - 4) = 60 ← distribute parenthesis on left side by b

b² - 4b = 60 ( subtract 60 from both sides )

b² - 4b - 60 = 0

(b - 10)(b + 6) = 0

equate each factor to zero and solve for b

b - 10 = 0 ⇒ b = 10

b + 6 = 0 ⇒ b = - 6

however, b > 0 , then b = 10

and h = b - 4 = 10 - 4 = 6

then base is 10 ft and height is 6 ft

The area of the rhombus with length of diagonals 12 cm and 12 cm is 72 centimetre squared.

The area of a rhombus can be represented mathematically as follows:

area of a rhombus  = ab / 2

where

a = 6 + 6 = 12 cm

Therefore, let's find b

tan 45 = opposite / adjacent

tan 45 = 6 / x

x = 6 / tan 45

x = 6 / 1

x = 6

b = 6 + 6 = 12 cm

Therefore,

area = 12 × 12 / 2

area = 144 / 2

Step-by-step explanation:

Cheko must give $110 to Miko so that each of them has an equal amount of pocket money, which is $550.

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

We have,

The ratio of Miko's pocket money to Cheko's pocket money.

= 8:12

= 2:3

Now,

Let's represent Miko's pocket money as 2x and Cheko's pocket money as 3x.

We know that,

3x = $660
x = $220

Miko's pocket money.

= 2x

= 2($220)

= $440.

To make their pocket money equal,

Cheko needs to give half of the difference between their pocket money to Miko.

The difference between their pocket money.

= $220 (i.e., $660 - $440).

Half of that is $110.

Therefore,

Cheko must give $110 to Miko so that each of them has an equal amount of pocket money, which is $550.
