The correct options are B and C.
Answer:
48π
Step-by-step explanation:
Given that,
The radius of the sphere is increasing at a rate of 3cm/minute,
The volume of a sphere is given by :
Differentiating both sides wrt t.
Put r = 2 cm and dr/dt = 3 cm/minute
So,
Hence, the correct option is (a) "48π".
No, C is correct. 13 and 2 are prime numbers, 6 is not
Answer:
Answer D
Step-by-step explanation:
Triangle XYZ is rotated by a composition of 50°+40°=90° counter-clockwise. When a geometrical figure is rotated by any degree, then its shape or size does not change. A 90 degree rotation is a rotation by one quadrant, if you think of it on a coordinate plane. This inference should show you that choice D is the correct answer.
I believe it would be jack Dorsey and jim Mckelvey since they were the ones who made the perfect square
