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
<span>When you multiply a number by 10, 100, 1,000 and so forth, you move the decimal point to the right as many places as there are zeroes in the multiplier. When you’re multiplying, the order of the factors do not matter because you will still get the same answer. The law of grouping do not apply to multiplication.
The answers for the following numbers are:
a. 24.6 × 100 = 2,460
b. 37 × 1,000 = 3,700
c. 0.367 × 10,000 = 3,670
d. 0.005 × 100,000 = 500
</span><span>a. 973 × 80 = 77,840
b. 56 × 2,000 = 12,000
c. 5.7 × 300 = 1,710
d. 0.46 × 50 = 23</span><span>

The disease is rare with a prevalence of <span>one out of every thousand people have it. That means, the chance of Roberto has the disease without any test would be 1/1000 or 0.1%
The test sensitivity is 99%, which mean 99% of people with positive test result would have the disease. The chance is should not be influenced by the disease prevalence. </span>
