The long jump record, in feet, at a particular school can be modeled by f(x) = 19.6 + 2.5ln(x + 1) where x is the number of years since records began to be kept at the school. what is the record for the long jump 11 years after record started being kept? round your answer to the nearest tenth.

25.8

Step-by-step explanation:

The question is:

Evaluate 6t−20−32u when t=6 and u=1/4

8

Step-by-step explanation:

The given expression is:

We need to evaluate the expression for the given values of t and u. Substituting t=6 and u=1/4 in the above expression we get:

Thus, the give expression is equal to 8 for t=6 and u=1/4
