y-5x-7=0

Step-by-step explanation:

m = -2-3/1-2

m=5

y-y1 = m(x-x1)

y-2=5(x+3)

y-2=5x +5

y-5x-7=0

Answer:

In Geometry, we have several undefined terms: point, line and plane. From these three undefined terms, all other terms in Geometry can be defined.

Step-by-step explanation:

Answer:

point, line and plane.

Step-by-step explanation:

all other terms in Geometry can be defined.

Answer:

a. 482

b. 9.0

Step-by-step explanation:

The speed of the plane in still air is approx 482 miles per hour(mph). The speed of the jet stream, rounded to the nearest whole number, is 9 mph

Flight speed in air stream = Flight speed in still air + effect of air stream

If the flight is going opposit, then:

If the flight is going along with flight, then:

For this case, we're specified that:

Speed of flight along the stream is:

[tex]S = \dfrac{\delta D}{\delta T} = \dfrac{3930}{8} = 491.25 \: \rm mph[/tex]

Speed of flight against the stream is:

[tex]S = \dfrac{\delta D}{\delta T} = \dfrac{3930}{8.3} \approx 473.49 \: \rm mph[/tex]

Let the speed of air stream be y, and that of the flight in still air be x miles per hour, then we get:

Along air stream:

[tex]x + y =491.25\\[/tex] (in miles per hour)

and Against the stream:

[tex]x - y =473.49\\[/tex] (in miles per hour)

Adding both the equations side by side, we get:

[tex]2x + y - y = 491.25 + 473.49\\\\x = \dfrac{964.74}{2} =482.37 \: \rm mph[/tex]

Using this value, we get the value of y as:

[tex]x + y =491.25\\y = 491.25 - x = 491.25 - 482.37 = 8.88 \: \rm mph[/tex]

Rounding to the nearest whole numbers, we get:

x = 482 mph, and y = 9 mph

Thus, the speed of the plane in still air is approx 482 miles per hour(mph). The speed of the jet stream, rounded to the nearest whole number, is 9 mph

Answer:

2

Step-by-step explanation:

Answer:

11.25 or 11 1/4

Step-by-step explanation:

seeing as how tiled in this sense essentially means 'cut' we have to look at the following rectangle as 2 separate rectangles instead of one whole

so we'll let the biggest rectangle be rectangle one and the smallest rectangle two-

now we need the dimensions of each one-

rectangle one

l=5 w=2

rectangle two

l=5 w=1/4

now let us set up the equation and solve-

a=lw

rectangle one

a=5*2=10

rectangle two

a=5*1/4=1.25

and the last step is to add together the areas of both rectangles

10+1.25=11.25

and since you need your answer as a mixed number the answer is 11 1/4

(to do this you just put 11.25 over 100 and then simplify)

good luck :)

Step-by-step explanation:

Answer:

1028.5 is the mean

Answer:

481.75

Step-by-step explanation:

To find the mean add up all the numbers in the data set :

8 + 445 + 276 + 1198 = 1927

divide the numbers by how many numbers are in the data set :

1927 ÷ 4 = 481.75

Therefore, the mean in the data set 481.75

Answer:

23.2, exact is 22.9333334

Step-by-step explanation:

Step-by-step explanation:

Answer:

[tex]a_n=2n[/tex]

Step-by-step explanation:

The given sequence is 2, 4, 6, ....

We need to write an explicit formula for [tex]a_n[/tex]. The firts term is 2, second term is 4 and third term is 6 and so on.

Each term is 2 greater than the term before it. Thus we can write it as follows :

[tex]a_n=2n[/tex]

Where

n = 1,2,3....

Hence, the explicit formula is [tex]a_n=2n[/tex].
