B. (-2,1)

By checking the x coordinates, I saw there was two -2, but the output was different, so one of them had to be taken out to make it a function.

Given:<br>AC – AR<br>&lt;1 = &lt;2<br>Prove:<br>&lt;3 =&lt;4<br><br>​
Katena32 [7]

Answer:

ΔCTA ≅ ΔDRA

Step-by-step explanation:

Triangles CTA and DRA are congruent by ASA postulate. This is because:

  • ∠1 ≅ ∠2 (given)
  • AC ≅ AR (given)
  • ∠A is the same for both triangles (they are opposite angles)

Then, correspondent angles and sides are congruent, for example, ∠3 ≅ ∠4

Answer:

The change of concentration surely made the difference since the last drink contained more juice with respect to the water

Step-by-step explanation:

The concentration of a drink

We can know how much of a certain ingredient there is with respect to the entire mix. This is known as the concentration and is commonly expressed in percentage %

Sylvia and her friends made a drink with 6 quarts of pineapple juice in 4 quarts of sparkling water. The total quantity of water is 10 quarts, so the concentration of pineapple juice is

\frac{4}{10}=\frac{2}{5}=40\%

The next week, their drink consisted of 5 quarts of pineapple juice and 3 quarts of sparkling water, so the new concentration is

\frac{5}{8}=62.5\%

The change of concentration surely made the difference since the last drink contained more juice with respect to the water

B(7,8) and B’(-8,-7) represent a 90 degree clockwise rotation. true or false?
Juli2301 [7.4K]

90 degree clockwise rotation is described by the matrix,

\begin{bmatrix}0&1\\-1&0\\ \end{bmatrix}

If you apply the matrix to the vector B you get,

\begin{bmatrix}0&1\\-1&0\\ \end{bmatrix}\begin{bmatrix}7\\8\\ \end{bmatrix}=\begin{bmatrix}7\cdot0+8\cdot1=8\\ -1\cdot7+8\cdot0=-7\\ \end{bmatrix}

So false.

Hope this helps.
