IT SHOULD BE 9:26 BECAUSE TIME STARTS OVER AT 12:59 SO IF YOU COUNT 1,2,3,4,5,6,7,8,9 THEN ADD 26 IT IS <em><u>9:26</u></em>
Answer:
1, 9
Step-by-step explanation:
You're looking for the values of x where f(x) = g(x). Find the matching f(x) and g(x) values in the table. The value of x on that line is one of the solutions.
It’s 1,600 because 100times 10 is 1000 and 6 times 10 is 60 so 106 times 10 you just add 2 zeros and you get 1,600
Be just a bit clearer, please: "find the vertex."
You could either "complete the square" or use the "quadratic formula."
Here the coefficients are a=-1, b=11 and c=-18. Because a is -, the curve opens downward and the vertex is on top, representing the function's maximum.
Use the quadratic formula with the coefficients given above.
-b plus or minus sqrt(b^2-4ac)
x = -------------------------------------------
2a
#3 it will take him 40 mins because 8×5=40
