Please note that in such questions, the ":" stands for ratio which in turn stands for divide. Thus, the given expression which is:
will become:
.....(Equation 1)
Now, we know that 3.8 can be rewritten as 
. Also, we know that the mixed fraction 
can be re-written as:
Using the above two expressions in (Equation 1) we get:
Cross-multiplication gives:
Or c=0.25
Thus, we may write the value of c as either the decimal 0.25 or the fraction 
.
Answer:
We put the value of the x in the formula
f(6)=
Step-by-step explanation:
Than solve equation.
a. The center of the circle will be the coordinate point of the marked point inside the circle.
center: (3,-5)
The radius is the distance between the center and any point on the circle.
radius: 4 units
b. standard form for circles: (x-h)²+(y-k)²=r² where (h,k) is the center
standard form: (x-3)²+(y+5)²=16
c. Simplify equation in standard form to get general form.
(x-3)²+(y+5)²=16
x²-6x+9+y²+10y+25=16
general form: x²+y²-6x+10y+18=0
