Set up an equation 20=k(0.4)....to find k divide 20 by 0.4
It is the letter A your welcome
Y = 18( 0.58) ^t
It would be written as :
Y = 18(0.11) ^ (t/4)
Y = 18 (0.11 ^ (1/4)) ^ t
But
0.11 ^ (1/4) = 0.5759
Plug the value
Y = 18 (0.5759) ^ t
Two decimal point :
Y = 18 (0.58) ^ t
Answer: 49.2 cm
Explanation: I don’t know how to explain it without a visual so I hope you end up figuring it out! All I can say is: use Pythagorean’s theorem for that triangle to the left (if you know what I mean) to find the hypotenuse and then add all the sides up!
Have a great day!
