How to solve duoble angle formulas with an angle not on the unit circle

Mathematics

lord [1]3 years ago

I dont really know how to answer tht but hope this helps....A trigonometric equation is one in which the unknown to be solved for is an angle (call it θ) and that angle is in the argument of a trigonometric function such as sin, cos or tan. A trigonometric equation always has an infinite number of solutions, but it is customary to list only those angles between 0° and 360°.

Answer:

Option B

Step-by-step explanation:

First identify which options are a match for the hyperbola with a foci of (- 12, 6) and ( 6, 6 ). If there is only one, we can claim that that is the solution. Otherwise we would have to take the vertices into account,

The first option can be eliminated as it is present with a decimal in the denominator, indicating that the foci should also be a decimal. However, the foci of this option should be valuable to us -

\left(h+c,\:k\right),\:\left(h-c,\:k\right),\\\left(-3+c,\:6\right),\:\left(-3-c,\:6\right),\\c = ( About ) 3.6,\\\\Foci = \left(0.55808 ,\:6\right),\:\left(-6.55808,\:6\right)

The second option squares the denominators of the first option, so the foci should be the following -

Foci = ( - 12, 6 ), ( 6, 6 )

Which is the given! The rest of the options are similar to this second option, but are altered, thus don't have the same foci,

<u><em>Solution = Option B</em></u>

Evaluate the function below for x = 4.<br> F(x) = x3 + 2x2 + 1
pav-90 [236]

Answer:

77

Step-by-step explanation:

Plug in:

F(4) = (4)3 + 2(4)2 + 1

F(4) = 12 + (8)^2 + 1

F(4) = 12 + 64 + 1

F(4) = 77

(assuming 2x2 = 2x squared)

<h2>x = 13</h2>

Step-by-step explanation:

\frac{2x + 1}{3}  =  \frac{x + 5}{2}  \\ 2(2x + 1) = 3(x + 5) \\  \:  \:  \:  \: 4x + 2 = 3x + 15 \\ 4x - 3x = 15 - 2 \:  \\  \:  \:  \: x = 13
