Answer:

The scale factor is k = 1/30

a)

<u>The length of the wing on the model:</u>

  • 9 m * 1/30 = 900 cm * 1/30 = 30 cm

b)

<u>The area of the tail section of the plane:</u>

  • 80 cm² : (1/30)² =
  • 80 cm² * 900 =
  • 72000 cm² =
  • 72000 * (1/100)² m² =
  • 7.2 m²

Answer:

The real plane's tail section is 2400 cm^2

Step-by-step explanation:

Well since the model is 1/30 of the real planes size

By multiplying the area of the tail section by 30 we should get the area of the real tail section in the plane

80*30= 2400 cm^2

The real plane's tail section is 2400 cm^2

PLEASE HELP!!! Write the equation of a line that goes through the point (6, 3) and is perpendicular to the line y = 4x + 1.
Tpy6a [65]

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

y-y_ {0} = m (x-x_ {0})

Where:

m: It is the slope of the line and (x_ {0}, y_ {0})is a point through which the line passes.

We have the following equation of the slope-intersection form:

y = 4x + 1

Where the slope is m = 4

By definition, if two lines are perpendicular then the product of their slopes is -1.

Thus, a perpendicular line will have a slope:

m_ {2} = \frac {-1} {m_ {1}}\\m_ {2} = \frac {-1} {4}\\m_ {2} = - \frac {1} {4}

Thus, the equation will be of the form:

y-y_ {0} = - \frac {1} {4} (x-x_ {0})

Finally we substitute the given point and we have:

y-3 = - \frac {1} {4} (x-6)

Option B
