It took a submarine 30 seconds to sink 225 feet, moving at a constant speed. The captain wants to know the submarine's speed.
Vladimir [108]

Answer:

Speed per second= 7.5 feet per second

Step-by-step explanation:

Giving the following information:

We have a distance (225 feet), and a time (30 seconds). Also, we know that the speed was constant.

<u>All we have to do is divide the distance by the time and determine the speed per second:</u>

Speed per second= distance / time

Speed per second= 225 / 30

Speed per second= 7.5 feet per second

Is the expression below completely factored? If not, complete the factorization.
Ket [755]

Answer:

A) No, because the greatest common factor is 8y?, and the completely factored form is 8y2(4y2 - 6y + 3).

Step-by-step explanation:

Considering the expression

4y(8y3 – 12y2 + 6y)

From the elements in the parenthesis, 2 and y can still be factored out such that what will be left of each element

8y3/2y = 4y2

12y2/2y = 6y

6y/2y = 3

Hence

4y(8y3 – 12y2 + 6y) = 4y*2y(4y2 - 6y +3)

= 8y2(4y2 - 6y + 3)
