Answer:

MN = b - a

Step-by-step explanation:

N = $\frac{1}{2}$ BA

BA = a - b = 4a - 2b

$\frac{1}{2}$ BA = $\frac{1}{2}$ (4a - 2b) = 2a - b

Thus

MN = MO + OB + $\frac{1}{2}$ BA

= - 3a + 2b + 2a - b

= b - a

Answer:

$m(n) = 24 (0.75)^n$

Step-by-step explanation:

1) The two points are:

a) On the first swing she swings forward by 18 degrees: (1, 18)

b) On the second swing she only comes 13.5 degrees forward: (2,13.5)

2) The general equation using the form given is:

$m(n)=A(B)^n$

3) Substitute the two points:

$18=A(B)\\ \\ 13.5=A(B)^2$

4) Divide the second equation by the first one:

⇒ 13.5 / 18 = B

⇒ B = 0.75

5) Substitue B = 0.75 into the first equation:

18 = A (0.75) ⇒ A = 18 / 0.75 = 24

Hence, the equation is:

$m(n) = 24 (0.75)^n$
