Answer:
- 0.7
Step-by-step explanation:
We are given the general quadratic formula, as "
. " This can be represented by two separate formula's, which will come in handy when determining the positive and negative roots of the equation ( and here we need the negative root ):
1 )
,
2 ) 
We know that a = 1, b = - 5, and c = - 4 from the equation "
" ( which can be rewritten in the form
). Therefore, simply plug in these values into the quadratic formula to receive two solutions:
- This is our positive solution
__________
- And this is our negative solution
You can see that - 0.7 is the negative real number solution to Joline's quadratic equation!
Answer: I(x)=12x
Step-by-step explanation:
Let I represent the total money earned
Let x represent the number of toys sold
Since each toy is 12 dollars, then the company will earn 12 dollars for each toy that is sold.
Therefore, the equation is,
I(x)=12x
Sin(36)=a/16
16sin(36)=a
9.41=a
