Answer:
Step-by-step explanation:
pi*r^2=area
1*1=1
1*3.14=3.14
the area is pi itself
Answer:
(6x²-11x) that's the answer :)
The angles that are congruent to one are 4,5, and 8. So the answer would be B. 5.
Answer: a) -7/12 ft/s, -20 ft/s, -7 ft/s
b) 527/24 Ft²/s
c) 2/25 rad/sec
Step-by-step explanation:
a) b=7 ; a^2+b^2 = 25^2
a^2+b^2 = 625
Differentiate w.r.t = 2a (da/dt) + 2b ( db/dt) = 0

As found from above put a=24 b=7,15 and 24. You will get the reuqired answer.
b) Area of the triangle = 1/2 * b*h
differentiate wrt to time leads to the following relation:

c) sin (Θ) = b/25
differentiate it again to give

(X-7) is an answer and -300 is the reminder
