20,10,5, ...<br> Find the 9th term.

iren [92.7K]

Answer:

0.078125.

Step-by-step explanation:

This is a geometric sequence with first term a1 = 20 and common ratio r = 10/20 = 5/10 = 0.5.

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

9th term = 20(0.5)^(9-1)

= 20(0.5)^8

= 0.078125.

Mary is flying a kite and has let out 50 yards of kite string. Mary’s kite is directly above Erika.

ch4aika [34]

The distance of Erika from kite directly is 35.71 yards

Step-by-step explanation:

Considering the given situation as a right triangle with string as hypotenuse and the distance between both girls as base

So,

$h = 50\ yards\\b = 35\ yards$

As the triangle is a right triangle, we can use pythagoras theorem to solve this problem.

$h^2 = b^2 + p^2\\p^2 = h^2 - b^2\\p^2 = (50)^2 - (35)^2\\p^2 = 2500-1225\\p^2 = 1275\\\sqrt{p^2} = \sqrt{1275}\\p = 35.707\ yards$

Rounding off to nearest hundredth

=> 35.71 yards

Hence,

The distance of Erika from kite directly is 35.71 yards
