In June, Clarissa used 1 gigabytes of data on her cell phone. Given that June has 30 days, how much data did she use on average per day?​

Answers

Answer: 33.33 megabytes per day

Step-by-step explanation:

From the question, we are informed that in June, Clarissa used 1 gigabytes of data on her cell phone. Since June has 30 days, the amount of data she uses on average per day? will be:

= 1000megabyte/30

= 33.33mb

Note that:

1000 megabytes = 1 gigabyte

Subtract.
(3x - 8) - (x2 - 5x - 2)

Answers

Answer:

  -x^2 +8x -6

Step-by-step explanation:

Distribute the minus sign and collect terms.

  (3x -8) -(x^2 -5x -2)

  = 3x -8 -x^2 +5x +2

  = -x^2 +8x -6

WILL MARK BRAINLIEST TO QUICKEST ANSWER! PLEASE HURRYThe graph of the even function f(x) has five x-intercepts. If (6, 0) is one of the intercepts, which set of points can be the other x-intercepts of the graph of f(x)?

A.(–6, 0), (–2, 0), and (0, 0)
B.(–6, 0), (–2, 0), and (4, 0)
C. (–4, 0), (0, 0), and (2, 0)
D.(–4, 0), (–2, 0), and (0, 0)

Answers

There seems to be a flaw with this question because it says that there are five x-intercepts but the given information only gives you 4 x-intercepts to work with.

Even means the graph is symmetric about the y-axis

The best answer is A.(–6, 0), (–2, 0), and (0, 0)

because you do not have to worry about another point (0,0). Plus we need (-6,0) for it to be symmetric with (6,0).

Consider function f(x) = x²(x-6)(x+6)(x+2)²(x-2)². It is even and fits these conditions as it has x-intercepts at (6,0), (-6,0), (-2,0), (2,0), and (0,0). again, the question does not tell us the fifth x-intercept, so we need to assume that there is another one that needs to be there...and so (-2,0) must have (2,0) for it to be even as well.
The set of points are (0, 0)(–6, 0)

Answer:

  (-2, -2)

Step-by-step explanation:

Compare the two functions ...

  f(x) = -|x +2| -2

  f(x) = a·g(x -h) +k

where f(x) is a translation and scaling of function g(x). Here, you have ...

  g(x) = |x|

The scale factor is a = -1.

The horizontal shift is h = -2.

The vertical shift is k = -2.

_____

The original vertex at (0, 0) has been shifted by (h, k) to ...

  (0, 0) + (h, k) = (0, 0) + (-2, -2) = (-2, -2).

Answer:

(-2,-2)
