The weekly earning is an illustration of a linear function.
Her total earning when she sells a good worth $4800 is $637
The given parameters are:
Let the total sales be x and the total earnings be y.
So, we have:
Substitute known values
When she sold merchandise worth $4800, it means that <em>x = 4800</em>
So, we have:
Hence, her total earning is $637

Answer:
Step-by-step explanation:
(Tangent Length)^2 = y*(y + 11) You are going to have to use the quadratic formula on this.
Tangent Length = 7
7^2 = y * (y + 11)
49 = y^2 + 11y
0 = y^2 + 11y - 49
a = 1
b = 11
c = - 49
When you solve this quadratic equation you get
x1 = 3.40 which is the answer you go with.
x2 = -14.40 which can't be used. A negative length has no meaning.
