A curve is given the equation xy=25 and the equation of a line y=mx+b.
i. Express m in terms of b given that the line and the curve have one and only one point of intersection.
ii. If the line intersects the curve in two distinct points, find the set of values of b, given m=-5
Answers
Answer:
Below in bold.
Step-by-step explanation:
i, This is a rectangular hyperbola with symmetry about the line y = -x
If it touches the graph at one point only then
y = 25/x
y = mx + b so
25/x = mx + b
mx^2 + bx + 25 = 0
Using the quadratic formula:
x = (-b + sqrt(b^2 - 25*4*m)) / 2m
Now there's only one value of x so
b^2 - 25*4*m = 0
b^2 = 100m
m = b^2/100.
m = +/-b/10.
ii In this case b^2 > 100m
If m = |-5|
b^2 > 500
b > +/-√500
So b > √500 or b < -√500.
What’s the area of the shaded region???
Answers
Answer:
90
Step-by-step explanation:
Answer: So you need to find the area of the big circle and the little circle, if you add the diamaters they add up to 16 so we do pi*r^2 if the diameter is 16 we need the radius so we divide by 2, so we do pi*8^2, pi*64, 200.96 if we use 3.14, then we find the area of the little circle which is pi*r^2 which since the diameter is 8 we divide by 2 and get 4 so it is pi*4^2 which gets us pi*8 using 3.14 it is 25.12, now if we subtract 200.96-25.12 we get 175.84 mm
