Let the cost of the hair dryer equal x.
The net cost plus a 40% markup equals 42, set up an equation and solve forex.
1.4x = 42
Divide both sides by 1.4
X = 42 / 1.4
X = 30
The net cost was £30
Answer:
(0.4,1)
Step-by-step explanation:
I hope that this is for homework and not a quiz or test.
Since we already know the value of y which is 1, we can substitute it into the equation above it.
-5x+3=1
-5x=-2
x=2/5=0.4
So in (x,y) format (0.4,1)
Answer:
Answer: OPTION B
Step-by-step explanation
By definition, the parent function is the simplest form of a function. In this case, you have the quadratic parent function
As you can see in the graph, the function g(x) is the obtained by shifting the parent function f(x) two units to the right, which is represented with:
Therefore, the equation of the function g(x) is:
We start with the more complicated side which is the left side, and show that, on using some trigonometric identities, we will get the term on the right side .

Using Quotient identity for tangent function, we will get


Taking out sine function from the numerator

Cancelling the common term of numerator and denominator
