Dy/dx when y=x^2e^5x

1 answer:

4 0

I believe the problem asks for the slope. This problem can be done by putting y=x^2e^5x into slope intercept form. However, the issue is that there is the variable "e", which does not match the slope intercept formula, y=mx+b. Long explanation short, the slope is $3e^5x^2$

Answer:

2.- 100

Step-by-step explanation 1:

$\frac{7}{25} + \frac{3}{4} = \frac{28}{100} + \frac{75}{100} = \frac{103}{100}$

↑ As we can see, the only common multiple between 4 and 25 that is given to is 100.

Step-by-step explanation 2:

$\frac{(7 * 4) + (3 * 25)}{4 * 25} = \frac{28 * 75}{100} = \frac{103}{100}$

↑ Another way of knowing the answer is by using a fraction solving method. As we can see, the denominator is once again 100.

Nancy's mother has a large collection of footwear.

I think A, C, D are right because of the 12 pairs of heels, 6 are black (6/12) That means half of them could be chosen and be black (0.5). Another way to write 0.5 is as a percentage, 50%.
