Match each function formula with the corresponding transformation of the parent function y = (x - 1)2 1. y = - (x - 1)2 Reflecte
lawyer [7]

Answer:

  1. y = -(x-1)² . . . . reflected over the x-axis
  2. y = (x-1)² +1 . . . . translated up by 1 unit
  3. y = (x+1)² . . . . reflected over the y-axis
  4. y = (x-2)² . . . . translated right by 1 unit
  5. y = (x-1)² -3 . . . . translated down by 3 units
  6. y = (x+3)² . . . . translated left by 4 units

Step-by-step explanation:

Since you have studied transformations, you are familiar with the effect of different modifications of the parent function:

  • f(x-a) . . . translates right by "a" units
  • f(x) +a . . . translates up by "a" units
  • a·f(x) . . . vertically scales by a factor of "a". When a < 0, reflects across the x-axis
  • f(ax) . . . horizontally compresses by a factor of "a". When a < 0, reflects across the y-axis.

Note that in the given list of transformed functions, there is one that is (x+1)². This is equivalent to both f(x+2) and to f(-x). The latter is a little harder to see, until we realize that (-x-1)² = (x+1)². That is, this transformed function can be considered to be either a translation of (x-1)² left by 2 units, or a reflection over the y-axis.

The radius of the circle is 2 units
photoshop1234 [79]

Answer:

Diameter is basically double the radius, a physical representation of it is a full line that goes across the middle of the circle, if that makes sense. So you do 2 x 2 = 4 units

Hope that answers your question

Miguel is playing a game in which a box contains four chips with numbers written on them. Two of the chips have the number 1, on
creativ13 [48]

Answer:

The answer is "\bold{-\frac{1}{2}}"

Step-by-step explanation:

Miguel's choose the best way to win the 2 dollars by pulling the two chips with the number 1.  In total, there are four balls, so his probability of winning is:  

\to \frac{2}{4} \times \frac{1}{3}= \frac{1}{6}

The chances of losing a dollar add up to that amount, so 5/6.  

Price predicted = \frac{1}{6} \times (2) + \frac{5}{6}  \times (-1)

                          =\frac{1}{6} \times 2 + \frac{5}{6}  \times -1\\\\=\frac{1}{3} - \frac{5}{6}   \\\\=\frac{2-5}{6}\\\\=\frac{-3}{6}\\\\=- \frac{1}{2}\\

The final answer is "-\frac{1}{2}"
