What is the best method for determining an improvement curve slope

KonstantinChe [14]

Answer:

You calculate the derivative of a given function f(x), f'(x), and see when it is positive:

f'(x) > 0

It will give you an interval of values where the slope is positive.

In ΔWXY, x = 680 inches, w = 900 inches and ∠W=157°. Find all possible values of ∠X, to the nearest degree.

ikadub [295]

Given:

In ΔWXY, x = 680 inches, w = 900 inches and ∠W=157°.

To find:

The all possible values of ∠X, to the nearest degree.

Solution:

Law of Sines:

$\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}$

For ΔWXY,

$\dfrac{w}{\sin W}=\dfrac{x}{\sin X}=\dfrac{y}{\sin Y}$

Now,

$\dfrac{w}{\sin W}=\dfrac{x}{\sin X}$

$\dfrac{900}{\sin (157^\circ)}=\dfrac{680}{\sin X}$

$900\sin X=680\sin (157^\circ)$

$\sin X=\dfrac{680}{900}\sin (157^\circ)$

$\sin X=0.295219$

$X=\sin^{-1}(0.295219)$

$X=17.17067$

$X\approx 17$

Therefore, the value of ∠X is 17 degrees.

What’s the correct answer for this?

katovenus [111]

Answer:

FIRST option is the correct answer

Step-by-step explanation:

First option is the correct answer.

$(x+11)^2 + (y+ 6)^2 = 324\\ (x+11)^2 + (y+ 6)^2 = 18^2 \\$

Equating it with:

$(x-h)^2 + (y-k)^2 = r^2 \\- h = 11\implies h = - 11\\- k= 6\implies k = - 6\\Center = (-h, \: - k) = (11,\: 6)\\r^2 = 18^2 \\Radius= 18\: units$
