REVIEW: Find the slope for the following situations. a. Given the equation y = 5x + 1 b. Given the equation 2x + y = 6 c. Given
DanielleElmas [232]

Answer:

Part 1) The slope is m=5

Part 2) The slope is m=-2

Part 3) The slope is m=2

Step-by-step explanation:

Part 1) we know that

The equation of the line into slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem we have

y=5x+1

so

the slope is m=5

Part 2) we know that

The equation of the line in standard form is equal to

Ax+By=C

where

the slope is equal to m=-\frac{A}{B}

in this problem we have

2x+y=6

so

A=2,B=1,C=6

substitute

m=-\frac{2}{1}

m=-2

Part 3) we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

A(2,3)\ B(5,9)

Substitute the values

m=\frac{9-3}{5-2}

m=\frac{6}{3}

m=2

9. The function f (x) is shown graphed below. The function g is determined by the formula g(x) = 3f (x)-2 for all values of x in
Lady_Fox [76]

Answer:

  (1)  -5

Step-by-step explanation:

Put the value where the variable is, read the graph, and do the arithmetic.

  g(2) = 3f(2) -2 = 3(-1) -2

<em>   g(2) = -5</em>

__

<em>Additional comment</em>

f(2) is the point on the graph where it is 2 units to the right of the y-axis. At that point, the graph is 1 unit below the x-axis, so f(2) = -1.

<h3>Given:</h3>
  • w= 6 units
  • h= 6 units
  • l= 10 units
<h3>Note that:</h3>
  • w: width
  • h: height
  • l: length
<h3>To find:</h3>
  • The volume of the given triangular prism.
<h3>Solution:</h3>
  • Triangular prism is a 3 sided prism with same area of cross section with 2 triangular bases.

\large\boxed{Formula: V= \frac{wl}{2}×h}

Let's solve!

First, let's multiply width and height.

6×6

= 36

Now, we'll have to divide the answer by 2.

\frac{36}{2}

= 18

Then, multiply the answer by length.

18×10

\large\boxed{V= 180 \: {units}^{3}}

<u>Hence</u><u>,</u><u> </u><u>the</u><u> </u><u>volume</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>given</u><u> </u><u>triangular</u><u> </u><u>prism</u><u> </u><u>is</u><u> </u><u>1</u><u>8</u><u>0</u><u> </u><u>cubic</u><u> </u><u>units</u><u>.</u>

Adam must fly home to city A from a business meeting in city B. One flight option flies directly to city A from​ B, a distance o
g100num [7]

Answer:

The value  is  k =109.6 \ miles

Step-by-step explanation:

The diagram illustrating the question is shown on the first uploaded image

From the question we are told that

   The distance from city A to B is   AB =  467.3 miles

   The bearing from B to  C is  \theta_{BC} =  N 28.7E

   The bearing from B to  A is  \theta_{BA} =  N 60.7E

   The  bearing from A to  B is   \theta_{AB} =  S60.7W

    The  bearing from A to  C is   \theta_{AC} =  S79.1W

Generally from the diagram

     \theta_A  =  180 - 60.7 -79.1

=>  \theta_A  =  40.2 ^o

Also

     \theta_B  =  32^o

and  

      \theta_C  =  180 - (\theta_A  +\theta_B )

=>   \theta_C  =  180 - (40.2  + 32 )

=>   \theta_C  =  107.8 ^o

Generally according to Sine Rule

     \frac{BC}{sin (\theta_A)}  = \frac{CA}{sin (\theta_B)} =\frac{AB}{sin (\theta_C)}

=>   \frac{BC}{sin (40.2)}  = \frac{CA}{sin (32)} =\frac{467.3 }{sin (107.8)}    

So

     \frac{BC}{sin (40.2)}  = \frac{467.3 }{sin (107.8)}

=>  BC = 316.8 \ miles

Also  

    \frac{CA}{sin (32)} =  \frac{467.3 }{sin (107.8)}

    CA = 260 .1 \ miles

Generally the additional flyer miles that Adam will receive if he takes the connecting flight rather than the direct​ flight is mathematically represented as

      k = [CA +BC]  - AB

=>     k = [260 .1 +316.8]- 467.3

=>  k =109.6 \ miles
