Answer:
Step-by-step explanation:
4³/4⁻⁶ = 4³⋅4⁶ = 4³⁺⁶ = 4⁹
10m/s
32m/s
83m/s
None of these
Answer :
C
Solution :
At any instant x2+y2=52
Differentiating w.r.t. time 2xxdt+2ydydt=0
Here dxdt=2,dydt=u⇒u=83m/s
F(-2) = 4x(-2) = -8;
g(f(-1))= g(-8) = 2x(-8) -1 = -16 - 1 = -17.
The correct answer is the last option
Sub the numbers in
7 + 9(6)
=7 + 54
=61
