Answer:
the first one
Step-by-step explanation:
<span>It doesn't matter that she guessed correctly on the first two questions, guessing the third question correctly is independent of guessing any other question correctly. Therefore, the probability is one out of four, 1/4.</span>
It's D. a, b, and c refers to the coefficients of the numbers.
Let u = 4x^2, then y=e^u
dy/dx= dy/du x du/dx
dy/dx= 8xe^4x^2
Then do product rule to find d2y/dx2
d2y/dx2 = 64 x^2 e^4x^2 + 8e^4x^2
Substitute d2y/dx2 and dy/dx into the equation then will get equal to zero
