Step-by-step explanation:

8x + x² - 2y + y² - 64 = 0

(x + 4)² + (y - 1)² - 81 = 0

(x + 4)² + (y - 1)² = 81

In the transformation ABC A'B'C', the preimage of B' is ____. . a0
Misha Larkins [42]

Answer:

Pre image of B' is B

Step-by-step explanation:

Given:

ABC is a triangle

A transformation is done on ABC so that the image is A'B'C'.

Note that transformations are of various types such as dilation, vertical shift, horizontal shift, rotation about a point, reflection on a line, etc.

In any type of transformation, corresponding vertices will be matched.  In other words, A will become A', B will become B' and C will become C'.

Because of the property of the transformation to keep images similar and also transforming correspondingly the vertices we get preimage of B' would be nothing but B itself.

Make U the subject of the formula <br> D = ut + kt2
natali 33 [55]

Remark

I'm going to interpret this equation as

D = ut + kt²  The only difference is the 2.

Solution

Subtract kt² from both sides.

D - kt² = ut   Now divide by u on both sides.

\dfrac{D - kt^2}{t} = \dfrac{ut}{t}

The t's cancel out. on the right.  You are left with u on the right.

\dfrac{D - kt^2}{t} =\text{u}

Flura [38]

<em>Answer:</em>

<em>Step-by-step explanation:</em>

Jonah knows that Mr. Robinson needs 14 tablets for a week's supply of an anti-inflammatory drug.

<em>Mr. Robinson is going on vacation and needs a 4-week supply.  </em>

<em>So </em><u><em>multiplying 4 with the weekly supply</em></u><em> will yield the required result.  </em>

So, number of tablets Jonia needs to fill is,

=4\times 14

=56

<em>Therefore, Jonah needs </em><u><em>56 tablets</em></u><em> in order to fill his prescription</em>
