This is a geometric sequence with first term a1 = -4 and common ratio r = 4

so nth term = a1* r^(n-1)

= -4 *4^(n-1)

5 miles ------> 8 km

we divide both sides by 5 to get the unit rate:

1 miles ------> 8/5 km

Therefore:

27.5 miles -----> 27.5 miles x (8/5) = 44 km

In the figure, what is the area of the shaded region?

Hatshy [7]

Use Pythagoras theorem
${(6 + 3)}^{2} + {x}^{2} = {15}^{2} \\ {x}^{2} = 144 \\ x = 12$
Two triangles are similar
$\frac{6}{9} = \frac{y}{12} \\ y = 8$
(6+3)*12/2 - 6*8 /2 = 30
