Answer:</h2>
<h2>
Step-by-step explanation:</h2>
In this problem we have two vectors:
So we need to find two things:
and:
FIRST:
In this case we have the multiplication of vectors by scalars. A scalar is a simple number, so:
SECOND:
If we name:
Then, is the magnitude of the vector . Therefore:
Answer:
Step-by-step explanation:
The standard form of an equation of a line:
We have the equation in the point-slope form. Convert:
<u><em>Answer: </em></u>
#9: 5
#10: -2
#11: -1.5
<em><u>Step-by-step explanation:</u></em>
<em><u>#9:</u></em> 3,8,13,18,23,(28),(33),(38),.. <em>Go up by 5 each time, so the common difference is </em><u><em>5</em></u><em>.</em>
<u><em>#10:</em></u> 11,9,7,5,3,(1),(-1),(-3),... <em>Go down </em><em>(-)</em><em> by 2 each time, so the common difference is </em><u><em>-2</em></u><em>.</em>
<u><em>#11:</em></u> 3, 1.5, 0, -1.5, -3, (-4.5), (-6), (-7.5),... <em>Go down </em><em>(-) </em><em>by 1.5 each time, so the common difference is </em><u><em>-1.5</em></u><em>.</em>
Answer:
h= -4.
Step-by-step explanation:
42= 6-9h
42-6=-9h
36=-9h
36/-9= -9h
-4=h
