What is the d/dx tan^3x

Bad White [126]

$\frac{d}{dx}(tan^{3}x) = \frac{d}{dx}(tanx)^{3}$
$= 3(tanx)^{2} \cdot sec^{2}x$

$\therefore \frac{d}{dx}(tan^{3}x) = 3tan^{2}x \cdot sec^{2}x$

Help me please. what is the solution for 4≤n−4

notka56 [123]

Answer:

n $\geq$ 8

Step-by-step explanation:

You add 4 to both sides to make n the only thing on one side. Then to make the answer look better you move n to the left side and flip the symbol because n changed sides.

$4\leq n-4\\ 4+4\leq n-4+4\\ 8\leq n\\ n\geq 8$

d1i1m1o1n [39]

Answer:

Sample A Estimate: 330

Sample B Estimate: 420

Sample C Estimate: 360

Median: 360

Range: 90

Step-by-step explanation:

For the sample estimate, multiply 600 by 11/20, 7/10, and 3/5 in order.

600 * 11/20

6600/20

330 people for Estimate A.

600 * 7/10

420/10

420 people for Estimate B.

600 * 3/5

1800/5

360 people for Estimate C.

330, 360, 420

360 is the median of these estimates.

420 - 330 = 90

90 is the range of these estimates.
