The expression of the height is

$a_n=8\cdot (\frac{1}{2})^{n-1}$

the index "n" is the numbers of times that the ball is down, to n=1 the height is 8 inches, to n=2 the height is 4 inches.

An when n=5, the height is

$a_5=8\cdot (\frac{1}{2})^{5-1}=8\cdot (\frac{1}{2})^4=\frac{1}{2} =0.5$

the anwers is 0.5 inches

Find the missing length indicated. Leave your answer in simplest radical form.

Answer:

1). x = 81

2). x = 84

Step-by-step explanation:

1). By applying geometric mean theorem in the given triangle,

$\frac{x}{18\sqrt{14}}= \frac{18\sqrt{14}}{56}$

56x = (18√14)²

56x = 4536

x = $\frac{4536}{56}$

x = 81

2). By applying geometric mean theorem,

$\frac{x}{8\sqrt{21}}= \frac{8\sqrt{21} }{16}$

16x = (8√21)²

16x = 1344

x = $\frac{1344}{16}$

x = 84

18=a Over 2 How do you solve that as a one step

Aloiza [94]

Multiply both sides by 2
(2) 18 = x/2 (2)
the /2 (2) gets canceled out
so it's 36= x

Hope this helps

If y varies directly with x, write an equation for the direct variation. Then find each value.

Viktor [21]

1)
y = kx
-12 = k(9)
k = -4/3

y = (-4/3)(-4)
y = 16/3

2)
y = kx
8 = 20k
k = 2/5

y = (2/5)(10)
y = 4

3)
y= kx
-6 = k(-14)
k = 3/7

-4 = (3/7)x
-4(7/3) = x
x = -28/3
