Answer:
We can have two cases.
A quadratic function where the leading coefficient is larger than zero, in this case the arms of the graph will open up, and it will continue forever, so the maximum in this case is infinite.
A quadratic function where the leading coefficient is negative. In this case the arms of the graph will open down, then the maximum of the quadratic function coincides with the vertex of the function.
Where for a generic function:
y(x) = a*x^2 + b*x + c
The vertex is at:
x = -a/2b
and the maximum value is:
y(-a/2b)
Answer:
58 minutes.
Step-by-step explanation:
From the question, Karen worked on the model in two windows;
1) 11.13 AM - 11.54 AM = 41 minutes
2) 1.29 PM - 1.46 PM = 17 minutes.
Hence, the total amount of time Karen spent working on the Shuttle model is:
41minutes + 17minutes = 58 minutes.
Answer:
Step-by-step explanation:
the standard equation of a line is in the form y=mx+b where m is the slope and b is the y intercept so if m = 1/4 and b = -3/4 you can just replace those spots giving you y=1/4x+-3/4
step 2 would be 10
step 4 would be 10x-x = 9x =7
x = 7/9
