Answer:
Step-by-step explanation:
n²+2 where n is number of small squares forming maximum corner square.
in step 1,n=1
step 2,n=2
step 3,n=3
step 4,n=4
when n=1
number of squares=1²+2=1+2=3
when n=2
total numbers=2^2+2=4+2=6
when n=3
total numbers=3²+2=9+2=11
when n=4
total numbers=4²+2=16+2=18
The answer is going to be five because five plus five is ten!!!
We are given with the equation <span>f(x) = ax3 + bx2 + cx + d
Substituting, (3,11)
</span><span>11= 27a + 9b + 3c + d
</span><span>@(5, 9)
</span><span>9 = 125 a + 25 b + 5c + d
@</span><span>(4, 10)
</span><span>10 = 64 a + 16 b + 4c + d
@inflection point, second derivative is equal to zero
</span><span>f'(x) = 3ax2 + 2bx + c
</span>f''(x) = 6ax + 2b = 0
when x is 4, 24 a + 2b = 0 or 12a + b = 0.
There are 4 equations, 4 unknowns: answer is
<span>0.5 x^3 - 6x^2 + 22.5 - 24 = 0</span>
