Answer:
Option a.
Step-by-step explanation:
By looking at the options, we can assume that the function y(x) is something like:
such that, y(0) = √4 = 2, as expected.
Now, we want to have:
replacing y' and y we get:
Now we can try to solve this for "a".
If we multiply both sides by y(x), we get:
We can remove the x factor in both numerators if we divide both sides by x, so we get:
Now we just need to isolate "a"
Now we can subtract a*x^2 in both sides to get:
Then the solution is:
The correct option is option a.
it is given in the question that
You order two tacos and a salad.the salad cost $2.50.you pay 8% sales tax and leave a $3 tip.
Let the price of taco be $ x .
And 8 % of 2.50 is
So the equation is
So the price of the Taco is $4.05 .
