Answer:

sec theta = (sqrt24/5) cos theta = -2/5 tan theta = (-[sqrt 21]/2) sec theta = 5/2 csc theta = (5sqrt21)/21 cot theta = (-2sqrt21)/21

Step-by-step explanation:

During the problem, secx = -5/2, we can assume that as cos = -2/5. -2 = x. 5 = r. find for Y with: x^2+y^2=r^2. After that, plug in for the variables and you get all the answers. Rationalize the square roots, don't forget.

Svetllana [295]

Answer:

correct value of x = 5

Step-by-step explanation:

$\frac{ {( - 2)}^{4x + 2} }{ {( - 2)}^{2x} } = {( - 2)}^{12} \\ = \frac{ {( - 2)}^{4 \times 5 + 2} }{ { ( - 2)}^{2 \times 5 } } \\ = \frac{ {( - 2)}^{22} }{ { ( - 2)}^{10} } \\ = \frac{4194304}{1024} \\ = 4096 = 4096(i.e \: {( - 12)}^{12} = 4096) \\$

Need answer to this problem

Lana71 [14]

Distribute the exponent in the numerator:

$\dfrac{(10w^3)^2}{5w}=\dfrac{10^2w^6}{5w}$

Then if $w\neq0$ , we can cancel one of each $w$ in the numerator and denominator:

$\dfrac{10^2w^6}{5w}=\dfrac{10^2w^5}5$

Finally, the square of 10 is 100, and 100 divided by 5 is 20, so we're left with (C),

$20w^5$
