A scale model of an airplane has a length of 19 centimeters and a wingspan of 18 centimeters. The length of the real airplane is
deff fn [24]
The wingspan is 36 m.

Using a proportion to solve this, we write the scale factor as a ratio first:  19/38, since 19 is the size of the model's length and 38 is the real length.  For the second ratio, we have 18 for the size of the model wingspan and x for the real wingspan:

19/38 = 18/x

Cross multiply:
19*x = 38*18
19x = 684

Divide both sides by 19:
19x/19 = 684/19
x = 36 m

Equation of the tangent line
GalinKa [24]
Find the eqn. of the tangent line to the curve of f(x) = x^2 + 5x -5 at (0,-5).

Differentiate f(x) to obtain an expression for the derivative (slope of the tangent line):

             f '(x) = 2x + 5

Subst. 0 for x here:  f '(0) = 2(0) + 5 = 5     (at the point (0, -5))

Use the point-slope equation of a str. line to find the eqn of the tan. line:

y-k = m(x-h), where (h,k) is a point on the line and m is the slope:

y - [-5] = 5(x-0), or y+5 = 5x.  Then y = 5x - 5 is the eqn. of the TL to the given curve at (0,-5).
