If a basketball is bounced from a height of 20 feet, the function f(x)= 20 (0.9)^x gives the height of the ball in feet of each bounce number. What will be the height of the 6th bounce? Round your answer to the nearest tenth of a foot

10.6 feet to the nearest tenth.

Step-by-step explanation:

The first bounce will rise to the height 20(0.9)^1   ( putting x = 1).

= 18 feet.

So the height of the 6th bounce will be

20(0.9)^6

= 10.6 feet.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

i think it is 70
