Answer:
30+6+80+1= 117
Step-by-step explanation:
We can factor a polynomial by finding its roots. In particular, a quadratic equation has (at most) two roots , which would allow us to write the polynomial as
To find the solutions, we can use the quadratic formula
So, the two solutions are
And so we can factor the polynomial as follows:
We are given points (30,4) , (60,8) and (90,12)
To calculate the rate per minute at which the air freshener dispenses sprays,
we can use two points to find slope.
The formula for slope is given by :
let us use two points (60,8) and (90,12) to find the slope,
Slope = 4/30
So the rate per minute at which the air freshener dispenses sprays is 4/30.
So first option is correct answer .
