<h3>Explanation:</h3>

The note "SAS Congruence" under the middle box tells you this proof will be accomplished by showing two sides and the included angle are congruent. (That's what S A S refers to.)

One of the angles is shown in the upper left box as ∠TMI. The note under that box tells you the other angle is a vertical angle with ∠TMI. By referring to the diagram, you see that the vertical angle is ∠EMR.

The middle box on the left and the bottom box on the left share the note "M is a midpoint." This tells you the segments of interest are the congruent segments of which M is the midpoint. The <em>Given</em> information tells you M is the midpoint of ET and of RI. The middle left box is already filled with TM ≅ EM, so the bottom box needs to be filled with the letters of the other segments: RM ≅ IM.

The three congruence relationships on the left, involving an angle and two  sides either side of that angle mean that you can invoke the SAS Congruence theorem to say ΔTMI ≅ ΔEMR. Be sure to write the triangle names so that T corresponds to E, and I corresponds to R. This is the relation that goes in the middle box.

The right side box is the desired conclusion, the whole point of the proof: ∠T ≅ ∠E. The corresponding note is "CPCTC" (corresponding parts of congruent triangles are congruent).

Answer:

y = 2x + 7

Step-by-step explanation:

Use Point Slope Form since we are given the slope and coordinates. Why is the slope 2x?

<em> </em><em>In</em><em> </em><em>Depth</em><em>:</em><em> </em><em>Parallel lines never touch so</em><em> </em><em>they</em><em> </em><em>are</em><em> </em><em> Lines that have same slope but different y intercept</em><em>.</em><em> An example is a square. A square has four parallel sides. The upper and lower sides will never touch because they are the same slope and they both have a finite distance vertically between them. </em>

<em>Back</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>question</em><em>,</em><em> </em><em>let</em><em> </em><em>use</em><em> </em><em>the</em><em> </em><em>Point</em><em> </em><em>S</em><em>lope</em><em> </em><em>Form</em><em>,</em>

<em>y -  y_{1} = m(x -  x_{1})</em>

<em>Where</em><em> </em><em>y1</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>y</em><em> </em><em>coordinate</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>given</em><em> </em><em>point</em><em>,</em><em> </em><em>m</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>slope</em><em> </em><em>and</em><em> </em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>x</em><em> </em><em>coordinates</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>given</em><em> </em><em>points</em><em>.</em>

<em>Substitute</em><em> </em>

<em>y  - ( - 1) = 2(x - ( - 4)</em>

<em>y + 1 = 2(x + 4)</em>

<em>Simplify</em>

<em>y + 1 = 2x + 8</em>

<em>y = 2x + 7</em>

Find how many years it takes for money to triple when invested at an annual interest rate of 4.3% compounded continuously. That’
malfutka [58]

9514 1404 393

Answer:

  25.5 years

Step-by-step explanation:

The multiplier for continuous compounding at annual rate r for t years is ...

  e^(rt)

You want the value of t when that is 3 and r=0.043.

  3 = e^(0.043t)

  ln(3) = 0.043t

  t = ln(3)/0.043 ≈ 25.549 . . . . years
