Given:
are in geometric sequences.
To find:
The value of x.
Solution:
If a, b, c are in geometric sequences, then
...(i)
It is given that are in geometric sequences. By using (i), we get
On further simplification, we get
Therefore, the value of x is 0.
Answer:
The unit cost is 6
Step-by-step explanation:
Notice how the first point lands on (2,12) and how a "unit cost" is per one unit. So, if you divide 12 by 2, you would get a unit cost of 6.
The given triangle is a right-angled triangle. This means that special trig identities can be applies
<u>These identities are as follows:</u>
sin (theta) = opposite / hypotenuse
cos (theta) = adjacent / hypotenuse
tan (theta) = opposite / adjacent
<u>Now, for the unknown theta in the triangle:</u>
The opposite side is 16 and the hypotenuse is 20
This means that we will use the <u>sin</u> not the cos as Bob did
<u>The solution will be as follows:</u>
sin (theta) = opposite / hypotenuse
sin (theta) = 16 / 20
theta = sin^-1(16/20)
theta = 53.13°
Hope this helps :)
