The scuba diver must descend 3 feet in the fifth minute to meet the goal.
Why?
To find how many feet does the scuba diver need to descend to reach the goal of 35 feet in 5 minutes, we need to calculate how many feet he did descend on the first 4 minutes.
So, calculating we have:

Hence, we can see that at the 4 minute, he has only descended 32ft. It means that he need to descend 3 feet more in the fifth minute.
Have a nice day!
Answer: Degree of polynomial (highest degree) =4
Maximum possible terms =9
Number of terms in the product = 5
Step-by-step explanation:
A trinomial is a polynomial with 3 terms.
The given product of trinomial: 
By using distributive property: a(b+c+d)= ab+ac+ad

Maximum possible terms =9
Combine like terms

Hence, 
Degree of polynomial (highest degree) =4
Number of terms = 5
Answer:
Answer is TU = 15cm since n = 6 and n + 9 is 6 + 9 which is 15
Answer:
No solutions
Step-by-step explanation:
Solve for x the system of two inequalities:

First, solve each inequality separately:
1.

2.

Now, we get

and

There are no common values for x, for which both inequalities hold, so the system of two inequalities has no solutions.
Because 6 * 8 + ( - 2 )* 24 = 48 - 48 = 0 , the vectora u and v are orthogonal ;
Two vectors are orthogonal if their dot product is zero.<span />
