which equation represents a parabola that opens upward, has a minimum at x = 3, and has a line of symmetry at x = 3?

Step-by-step explanation:

All the parabolas open upwards because they all have an 'a' value of a=1 which is positive.

The axis of symmetry of a parabola is calculated using the formula;

We have x=3 and a=1.

We substitute the values to get;

Therefore the equation is of the form;

Looking at the given options, the required equation is

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
