Answer:
y=75+2x
Step-by-step explanation:
Given data
Loading fee=$75
Charge per mile= $2
Let the distance be x
and the total charge be y
Hence the expression for the total charge is
y=75+2x
THE AREA OF THE RING WHICH IS INSIDE CIRCULAR TARGET IS 12CM.
Step-by-step explanation:
A circular target which is divided into four rings of equal areas as given in the information
The area of the circular target is
Area =
* R².
As per the given data radius of the target 'R' is 24cm,
Area of circular target =
* 24²
=> 576
.
let us consider radius of ring equals to 'r',
So, each of the ring has area of
=> Area of ring = (
* 576) / 4
=> 144 * 
Now let us consider area of the small ring inside circular target
Area of ring =
* r²
* r² = 144 
Taking off the
from both sides
r² = 144
r = 12.
Therefore radius of ring which is inside circular target is 12 cm.
The quadratic formula is expressed as:
x = (-b +/- √(b^2 - 4ac) ) / 2a
where a, b and c are the coefficients of the quadratic equation with the form ax^2 + bx + c=0
Therefore, the quadratic equation would be:
a = 3
b = -6
c = 8
x = (-(-6) +/- √((-6)^2 - 4(3)(8) ) / 2(3)
Hope this helps.
