Estimate the domain

natima [27]

Take a look at the horiz. line. It has arrows at both ends. That means that x goes on forever in both directions. Thus, the domain of this function is (-inf, +inf).

FIND Y IN XYZ, help please

kumpel [21]

Given:

In triangle $XYZ,m\angle X=90^\circ, m\angle Y=45^\circ, m\angle Z=45^\circ, XZ=y,YZ=15\sqrt{2}$ .

To find:

The value of y.

Solution:

In a right angle triangle,

$\sin \theta =\dfrac{Perpendicular}{Hypotenuse}$

Using the above ratio for the triangle XYZ, we get

$\sin Y =\dfrac{XZ}{YZ}$

$\sin 45^\circ =\dfrac{y}{15\sqrt{2}}$

$\dfrac{1}{\sqrt{2}}=\dfrac{y}{15\sqrt{2}}$

$\dfrac{15\sqrt{2}}{\sqrt{2}}=y$

$15=y$

Therefore, the correct option is C.

What are some differences between observational studies and experiments and what are issues that may arise during data collectio

gavmur [86]

The disadvantage of observational studies and experiments is the difficulty of collecting accurate data. In this case, the data that is collected may be unreliable since it underwent subjectively and not objectively. This may alter the results without you knowing it and will result in an unreliable interpretation of the data.
