Answer:

  f(x) = 2(x -3)² +5

Step-by-step explanation:

For vertex (h, k) and scale factor 'a', the vertex form is ...

  f(x) = a(x -h)² +k

We can fill in the values of h and k from your vertex, and use the values of the extra point to find 'a'.

  55 = a(-2 -3)² +5

  50 = 25a . . . . . . . . subtract 5

  a = 2 . . . . . . . . . . . divide by 25

So, the function is ...

  f(x) = 2(x -3)² +5

__

In standard form, that will be ...

  f(x) = 2x² -12x +23

Determine whether the number is a perfect square P.S there is a lot
mihalych1998 [28]

Answer:

okay so to figure out a perfect square a number has to be outlined by itself. 8 is not. 4 is because 2 times itself is 4. 81 is because 9 time itself is 81. 44 is not. 49 is because 7 times itself is 49. 125 is not. 150 is not. 144 is because 12 times itself is 144.

My grandson thinks he can cook better than any other
Molodets [167]

The answer is (B). Employing a comma to separate two independent phrases connected by the conjunction "and," avoids the mistake of the original.

<h3>What are jumbled words?</h3>

The reason was given for Wrong Answer A:  Incorrect coordination is present in Option (A). Where a comma is required, a semicolon is used instead.

The reason was given for the Wrong Answer C:  The sentence produced by option (C) is illogical. It illogically implies that the grandson's success in winning blue ribbons is due to his belief that he is the fair's top chef.

Justification for Wrong Answer D:  In the case of option (D), the sentence is irrational. The initial portion of the line, "To think... fair," and the latter section of the sentence has no connection to one another ("my grandson . . . to prove it.").

Justification for Wrong Answer E:  The sentence produced by option (E) is irrational. It is illogical to claim that the grandson's blue ribbons demonstrate that he was "thinking he can cook better... fair."

A student faculty government committee of 4 people is to be formed from 20 student volunteers and 5 faculty volunteers. Find the
Arte-miy333 [17]
A.) Probability of selecting two students and two faculty members from 20 students and 5 faculty volunteers = no of ways of selecting two students and two faculty members from 20 students and 5 faculty volunteers divided by the number of ways of selecting 4 people from 25 people = (20C2 x 5C2) / 25C5 = 1900 / 53130 = 0.036 = 3.58%

b.) Probability of selecting three students and one faculty members from 20 students and 5 faculty volunteers = no of ways of selecting three students and one faculty members from 20 students and 5 faculty volunteers divided by the number of ways of selecting 4 people from 25 people = (20C3 x 5C1) / 25C5 = 5700 / 53130 = 0.107 = 10.7%
