Let F of x equals the integral from 1 to 3 times x of the natural logarithm of t squared. Use your calculator to find F″(1).
eduard
Reading that as

F(x)=\displaystyle\int_1^{3x}(\ln t)^2\,\mathrm dt

By the fundamental theorem of calculus, the first derivative is

F'(x)=3(\ln(3x))^2

and so the second derivative would be

F''(x)=\dfrac{6\ln(3x)}x

which means

F''(1)=6\ln3

Shaneen has $30 to spend on CDs that each cost $10. She wants to calculate n, the number of CDs she can buy with her $30. Which
weqwewe [10]

Answer:

10n \le 30

n \le 3

Step-by-step explanation:

Given

Total = \$30

Cost (each) = \$10

Required

Determine the inequality

Assume she wants to buy n CDs.

If 1 CD costs $10, then n CDs costs 10n.

So, the inequality is:

10n \le 30

<em>We used </em>\le<em> because the amount she wants to spend cannot exceed 30</em>

Divide both sides by 10, to solve for n

n \le 3
