Answer:
y = 20·2^x
Step-by-step explanation:
Use the given points to write two equations, then solve for 'a' and 'b'.
20 = a·b^0 = a
5120 = a·b^8 = 20·b^8 ⇒ 256 = b^8
b = 256^(1/8) = 2
Your function is ...
y = 20·2^x
16.15 because 33,60-1.30 is 32.30. 32.30 divided by 2 is 16.15
Well 1.25 meters per second so 1.25 x 8 = 10
so 10 meters in 8 seconds
