Answer:
C' = (2, 1)
Step-by-step explanation:
The co-ordinates of C from the graph is: C(6, 3).
When a co-ordinate is dilated by a factor, say 'a' then each term in the co-ordinate is dilated by 'a'.
Therefore, here, we will have: (6, 3)
= (2, 1)
Call this C'. Therefore, the co-ordinate of C' = (2, 1).
Hence, the answer.
Answer:
Step-by-step explanation:
Use a cofunction identity on the right hand side or left hand side...
So .
We have the equation:
Make the above replacement:
Since cotangent has period 180 degrees, we can also write this as:
So solving the following will give us a set of solutions for :
Add on both sides:
Subtract 10 on both sides:
Divide both sides by 2:
Symmetric property:
Answer:
$1.6
Step-by-step explanation:
The price of $2.32 already includes the 45% mark up hence taking the original cost to be x, it means the cost of $2.32 is 145% of the original cost
Using the concept of cross multiplication we say that if
1.45 is equivalent to $2.32
1 is equivalent to x
Therefore, the company incurs $1.6 for each plug
