I think it May be b because it’s slope is rising by two
Step-by-step explanation:
step 1. the perfect square will look like this: (7x + a)(7x + a) = (7x + a)^2.
step 2. by performing FOIL you will get 49x^2 + 14xa + a^2.
step 3. 14a = 84. a = 6
step 4. a^2 = 36.
step 5. k = 36.
Answer:
Step-by-step explanation:
We are given that
Base side of square pyramid, a=3 m
Height of square pyramid, h=9m
We have to find the rate of change of the volume of the pyramid at that instant.
Volume of square pyramid, V=
Differentiate w.r.t t
Substitute the values
Hence, the rate of change of the volume of the pyramid at that instant=
