Answer:

The sentence that describes the reflected point (x,-y) over the y-axis

Step-by-step explanation:

Since not sure if specific options are available lets answer this question in a general notation.

Let us consider the Co-ordinate system in two dimensions (i.e.  and ); where the horizontal line represents the  values and the vertical line representes the  values.Now we are told that we have a point with a positive x-coordinate and a negative y-coordinate, thus:

This means our point is located at the 4th Quadrant (where  values are positive and  values are negative).

Reflecting it over the y-axis means that our point is now located on the 3rd Quadrant (where both  and  values are negative).

Therefore the new reflected point will now be:

''a point with a negative x-coordinate and a negative y-coordinate''

MissTica

The answer choice which represents the domain and range of the function h(t) as given in the task content in which case, values are rounded to the nearest hundredth is; Domain: [0, 3.85] and Range: [0, 18.05].

<h3>What are the domain and range of the function as given in the task content?</h3>

It follows from convention that the domain of a function simply refers to the set of all possible input values for that function.

Also, the range of a function is the set of all possible output values for such function.

On this note, by observing the graph in the attached image, it follows that the Domain of the function in discuss is; [0, 3.85].

While the range is the difference between the minimum and maximum height attained and can be computed as follows;

At minimum height, t = 0; hence, h(t) = 0.

At maximum height; h'(t) = 0 where h'(t) = h'(t)=-9.74t+18.75 and hence, t = 1.92.

Hence, h(1.92) = 18.05.

The range is therefore; [0, 18.05].

Verify the identity:<br> tan(x+pi/2)=-cotx<br><br> please!!
olya-2409 [2.1K]
First we use sin(a+b)= sinacosb+sinbcosa
and cos(a+b)=cosa cosb -sinasinb

tan(x+pi/2)= sin(x+pi/2) / cos(x+pi/2)
and sin(x+pi/2) = sinxcospi/2 + sinpi/2cosx =cosx, 
<span>cos(x+pi/2) = cosxcospi/2- sinxsinpi/2= - sinx, 
</span> because <span>cospi/2 =0,  </span>and <span>sinpi/2=1

</span><span>=tan(x+pi/2)= sin(x+pi/2) / cos(x+pi/2)= cosx / -sinx = -1/tanx = -cotx
</span>from where <span>tan(x+pi/2)=-cotx</span>

What do you do when your mom is crying? probably not the best place to ask but im grounded so i cant ask on any other platform l
FromTheMoon [43]

Answer:

Ask her why she is crying. If she explains why, listen and comfort her. If she says to "go away" or "i don't want to talk about it," give her space and come back later. She needs to let it out, so have patience :)

Hope this helps!!
