Answer: The co-ordinates of the point P after transformation are (4, -3).

Step-by-step explanation:  Given that a point P(-4, -3) is rotated Point P(−3, −4) is rotated 90° counterclockwise about the origin.

We are given to find the co-ordinates of its image after the transformation.

We know that,

If a point (x, y) is rotated 90° counterclockwise about the origin, then its co-ordinates after the transformation becomes

(x, y)  ⇒  (-y, x).

Therefore, if P changes to P' after the transformation, then co-ordinates of the point P' will be

P(-3, -4)  ⇒  P'(4, -3).

Thus, the co-ordinates of the point P after transformation are (4, -3).

The 90° CCW transformation is

... (x, y) ⇒ (-y, x)

For your point, this is ...

... (-3, -4) ⇒ (-(-4), -3) = (4, -3)

Sure.  From those choices, the only one that makes sense is that he
didn't perform enough trials.  Technically, you can't expect the experimental
probability to match the theoretical probability until you've rolled it an infinite
number of times.

I have a hunch that even for only 60 trials, such a great discrepancy between
theory and experiment is beginning to suggest that the cubie is loaded.  But
you really can't say.  You just have to keep trying and watch how the numbers
add up.

D) Suppose you pick one marble from the bag at random. Find the expected value of its number.
Vaselesa [24]

C) The probability that you pick at least one purple marble is 98%.

<h3><u>Probability</u></h3>

The question is incomplete, since the number of marbles of each color in the bag is missing: 3 blue, 5 green, and 2 purple marbles.

Now, to answer the questions, the following calculations must be done:

  • C) 100 - (2/9x9) = X
  • 100 - 2 = X
  • 98 = X

The equation a = 640s gives the relationship between s square miles and a acres. Pam owns 7.5 square miles of farmland. How many
stich3 [128]
Quantity of farmland owned by Pam = 7.5 square miles.
The other important information given in the question is the equation relating square miles and acres. Using that information, the answer to the question can be easily reached.
a = 640s
   = 640 * 7.5 acres
   = 4800 acres.
From the above deduction, we can conclude that the correct option among all the options that are given in the question is the third option or option "C".

Answer:

  6.5e^(i·(-157.38°)) ≈ 6.5e^(-2.7468i)

Step-by-step explanation:

A suitable calculator can find the value of this ratio for you.

  ((2+3i)/(1-i))² = -6 -2.5i ≈ 6.5∠-157.38° ≈ 6.5e^(-2.7468i)

__

The second attachments shows the calculator set to radian mode for the angle measure.
