Mathematics
1 answer:
Ulleksa [173]3 years ago
8 0

using the pythagorean theorem

a^2 +b^2 =c^2

x^2 + 8^2 = 15^2

x^2 +64 = 225

subtract 64 from each side

x^2 = 161

take the square root of each side

x =sqrt (161)

x=12.6886

PLEASE HELP!!! ASAP The function graphed approximates the height of a rock, in meters, x seconds after it falls from a cliff
nasty-shy [4]

The vertical numbers are the distance and the horizontal numbers are the time in seconds.

Look at where the line is located at the number 20.

It si between the 2 and the 3 on the horizontal line, but you can see it is closer to the 2 than it is the 3, so the time would be 2.2s

what is the recursive definition and explicit formula of the sequence 3, 5.5, 8, 10.5, 13, 15.5? I know the pattern is +2.5 ​
Delicious77 [7]

Answer:

a_{n} = a_{n-1} + 2.5

Step-by-step explanation:

This is an arithmetic sequence with common difference d = 2.5

The recursive formula allows any term in the sequence to be found by adding d to the previous term, thus

a_{n} = a_{n-1} + 2.5 ← recursive formula with a₁ = 3
