We use sin in vector product and not using cosine because
Sin function is natural for physical process,
The value arise from zero to max
Hope this helps
The team will not make the first down.
Here are the integers that are represented by the scenario.
-2 + -2 + -2 = -6
-6 + 12 = 6 yard gain.
They are 4 yards short of the first down.
Pile Y has the greater mean number of pages per book because it is 5 books less than pile W.
<h3>How to calculate greater mean number of pages?</h3>
From the complete information, we can deduce that the number of each pile of book is given as follows:
<u>For pile W;</u>
Red books = 10 × 5 = 50 red books.
Blue books = 5 × 5 = 25 blue books.
Therefore, total books in pile W = 50 + 25 = 75 books.
Mathematically, the mean for each pile can be calculated by using the following formula:
Mean = [F(x)]/n
Mean = 75/10
Mean = 7.5.
<u>For pile Y;</u>
Red books = 10 × 5 = 50 red books.
Mean = [F(x)]/n
Mean = 50/5
Mean = 10.
In conclusion, pile Y has the greater mean number of pages per book because it is 5 books less than pile W.

Answer:
18
Step-by-step explanation:
We are to determine the value of a
to do this we have to make a the subject of the formula. this can be achieved by taking the following steps
divide both sides of the equation - 2(42 - a) = 48 - by 2
42 - a = 24
take a to the right hand side and bring 24 to the left hand side
a = 42 - 24
a = 18
