Ana needs 40 mg of medicine twice a day. Each medicine tablet contains 15 mg, how many tablets will Ana need for 2 days?
Stella [2.4K]

Answer:

She will need 10 full tablets and two thirds of a tablet

Step-by-step explanation:

First we will find how many tablets ana needs for one day:

In each day ana needs 40x2 mg of medicine, they come in tablets of 15 mg. In one day, she needs 80 / 15 =  5 and 1/3 of a tablet.

In two days, she needs double that amount. (5 and 1/3) x 2 = 10 and 2/3

Write a quadratic function f whose zeros are 3 and 12.<br> f(x) = ?
ololo11 [35]

Answer:

The above equation is a quadratic function whose zeroes are 3 and 12.

Step-by-step explanation:

The general quadratic equation is given by :

ax^2+bx+c=0

It is given that, the zeroes of a quadratic function are 3 and 12. It means they must be factors of it such that,

(x-3)=0\\\\(x-12)=0

So, we can write as :

(x-3)(x-12)=0

Multiplying both factors,

(x-3)(x-12)=0\\\\x^2-12x-3x+36=0\\\\x^2-15x+36=0

So, the above equation is a quadratic function whose zeroes are 3 and 12.
