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.
Answer:
Principal amount (P) = $6000
Rate (R) = 12%
Time = 2 years
Simple interest, I = P X R X T / 100
= 6000 X 12 X 2 / 100
= 144000 / 100
= 1440
=> Simple interest, I = $1440
Amount they would owe at the end of 2 years,
= P + I
= 6000 + 1440
= $7440
Answer:
11
Step-by-step explanation:
3x - 7 = 26
+7 +7
3x/3 = 33/3
33/3 = 11
Since triangle ABC is a right triangle (90*), and angle ACB 45*, angle CAB must also equal 45*
Angles of triangle = 180=90+45+x
180=135+x
180-135=135-135+x
45=x
