Answer:
(0,3) ; (2,3) ; (0,0) ; (3.5,0)
Step-by-step explanation:
Firstly, we have to plot all the giving inequalities as constraints
Not to forget, f(x) can be written as y
Kindly find the plot as an attachment
Upon plotting, we have the following vertices;
(0,3) ; (2,3) ; (0,0) ; (3.5,0)
Answer:
a=3, b=-5, c=2
Step-by-step explanation:
0=3x^2-5x+2
a=3
b=-5
c=2
Answer:
16m
Step-by-step explanation:
Answer:
2½ h
Step-by-step explanation:
Assume the graph is like the one below.
The graph shows how Erin's distance varies with time.
To find out how long it takes Erin to cover 25 mi, find 25 mi on the vertical axis.
From there, draw a horizontal line until it hits the graph.
Then drop a vertical line to the horizontal axis.
It hits half-way between 2 and 3.
It takes Erin 2½ h to run 25 mi.
Cotx = Cosx/sinx
1/Cotx = sinx/cosx
Sinx + cosx *1/cotx = sinx + cosx * sinx/cosx = 2sinx
