An explicit formula for a sequence allows you to find the value of any term in the sequence. A recursive formula for a sequence allows you to find the value of the nth term in the sequence if you know the value of the (n-1)th term in the sequence.
84% of 50 is 42. So if your test was graded out of 50 you would've gotten 42/50. If you multiply 50 by 2 (50x2), you have 100, so then you'd just divide the 84% by 2 so you'd get 42%
a. 3^4 which is equal to (3^-3)(3^7)
Answer:
H= 121.25 meters
Step-by-step explanation:
To find the value of H after 30 months given the equation H=0.20x+115.25,
replace x by 30 in the equation and solve;
H=(0.20*30)+115.25
H=6+115.25
H= 121.25 meters
Therefore, the height will be 121.25 meters
