Answer:

(C)180° rotation

Step-by-step explanation:

For rotations about the origin, these are some basic rules

  • 90°clockwise rotation: (x,y)=(y,-x)
  • 90°counterclockwise rotation: (x,y)=(-y,x)
  • 180° rotation: (x,y)=(-x,-y)
  • 270°counterclockwise rotation: (x,y)=(y,-x)

Given point A(-3,4), x=-3, y=4

Point A'=(3,-4)=(-x,-y)

Therefore, the rotation that maps A to A' is 180 degrees rotation.

The correct option is C.

The daily water consumption for an Ohio community is normally distributed with a mean consumption of 722,500 gallons and a stand
Allisa [31]

Answer:

0.0060

Step-by-step explanation:

The z-score is given by

<em>z = (866,475-722,500)/57,429 = 2.51 </em>

The probability is given by the area under the Normal curve N(0,1) to the <em>right</em> of 2.51

In <em>Excel </em> this value is found with the formula

=1-NORMDIST(2.51,0,1,1)

and in <em>OpenOffice Calc </em>

=1-NORMDIST(2.51;0;1;1)

<em> (NORMDIST(2.51;0;1;1) gives the area to the left of 2.51, so 1-NORMDIST(2.51;0;1;1) gives the area to the right of 2.51) </em>

and equals 0.0060

Which graph represents exponential decay?
Reika [66]
Answer: the first graph


Reasoning: When a graph is going left to right it is a decay while when it’s going right to left it is an increase... think of linear equations where if it is going from left to right the slope is negative, it’s the same for the exponential decay and increase.
