Answer:
7.5
Step-by-step explanation:

Answer:
.1 approx.
Step-by-step explanation:
5/60 and x/100%
Cross multiplying...
5 x 100% = 5
5/60 ~= .1
( I dunno if I am right, so please check first.)
Answer:20 ^v^ Please follow me
Step-by-step explanation:
200/40=5
5+15=20
Answer:
D-2
Step-by-step explanation:
You can use elimination to get the value of y. Move numbers to one side and x and ys to the other side. To use elimination, multiply the first equation with 2. You will get 2x+2y=24. add it with the equation below. y will be eliminated and you will get the value of x. X=10. Plug in x and get the y value. Y=2
First find the critical points of <em>f</em> :



so the point (1, 0) is the only critical point, at which we have

Next check for critical points along the boundary, which can be found by converting to polar coordinates:

Find the critical points of <em>g</em> :



where <em>n</em> is any integer. We get 4 critical points in the interval [0, 2π) at




So <em>f</em> has a minimum of -7 and a maximum of 299.
