Answer:

Step-by-step explanation:
<u>Factored form of a parabola</u>

where:
- p and q are the x-intercepts.
- a is some constant.
Given x-intercepts:
Therefore:


To find a, substitute the given point (4, 8) into the equation and solve for a:




Therefore, the equation of the parabola in factored form is:

Expand so that the equation is in standard form:




 
        
             
        
        
        
Answer:
2.871*10^9
Step-by-step explanation:
add a decimal point at the end of the number ( 2,871,000,000.) then count how many places it takes to move the decimal point between the first and second number (2.8) then write the rest of the numbers higher than "0" after, giving you the 2.871
to show that the number written is in scientific notation you add 10 to the power of the amount of times you moved the decimal place. In this case, because the decimal point was moved a total of 9 times, it would be 10 to the 9th power (10^9).
 
        
                    
             
        
        
        
Answer:
To multiply fractions, first we simplify the fractions if they are not in lowest terms. Then we multiply the numerators of the fractions to get the new numerator, and multiply the denominators of the fractions to get the new denominator.
