Explain how to graph the given piecewise-defined
Pavlova-9 [17]

The Piecewise -Defined function and how it is graphed is given below..

<h3>What is the explanation of how the Piecewise -Defined function is graphed?</h3>

Given the function in the attached image,

  • The Graph of f(x) = -x + 3 is drawn for x less than 2 because x is bounded.
  • The Graph of f(x) = 3 is draw for x greater than and equal to 2 and less than 4 because x is bounded.
  • The Graph of f(x) = 4 - 2x is draw for x greater than equal to 4 because x is bounded.

See the attached Graph for better understanding.

  • f(x) = -x + 3 is coded purple.
  • f(x) = 3 is coded orange.
  • f(x) = 4 - 2x is coded green.

Principle=$745 rate= 9% time= 4years
Dennis_Churaev [7]
Based on a yearly rate (which is the norm) I give you my answer ..

Your principle is at 745$
Annual Rate 9%

For the first year your principle will grow by 67.05 $ if untouched (9%) up to 812.05 $

2nd year .. 9% of the 812.05 $ is 73.0845 $ .. So by the 2nd year you reach 885.1345 $

3rd year .. 79.662105 $ .. Total 964.796605 $

4th year .. 86.83169445 $ .. <u>Final</u><u> 4 Years </u><u>Total 1051.62829945 $</u>

Given that AB parallels QR, AB bisects AE, QR bisects QT
enyata [817]

Answer:

  1. Dilate ΔABE by a factor of 2/5 to make ΔA'B'E'

  2. Translate A' to Q

Step-by-step explanation:

We notice the triangles have the same orientation, so no reflection or rotation is involved. The desired mapping can be accomplished by dilation and translation:

  1. Dilate ΔABE by a factor of 2/5 to make ΔA'B'E'

  2. Translate A' to Q

The result will be that ΔA"B"E" will lie on top of ΔQRT, as required.
