Answer:
the third option
Step-by-step explanation:
Our equation is
Equation of a vertical parabola is
where (h,k) is the center
The focus is
(h+p, k)
Equation of directrix is
x= h-p,
Here the center is (10,0)
Next, we factor out 4 in the original equation
So we have
So our p=9,
So our focus is
(10+9,0) or (19,0)
The third option is the answer
Answer:
<em>The largest number of glasses of juice Isabella can have from the carton is 8.</em>
Step-by-step explanation:
<u>Ratios</u>
Knowing the total capacity of the carton of apple juice Ct, and the capacity of each glass Co, we can calculate how many glasses can be taken from the carton by finding the ratio:
There are 1,000 milliliters in one liter, thus the carton has a capacity of
C t= 1.75*1,000 = 1,750 milliliters
Thus,
n=8.75
Since we cannot have 8.75 glasses, we round to the previous integer, then:
The largest number of glasses of juice Isabella can have from the carton is 8.
