Answer:

  see attached

Step-by-step explanation:

The cosine function crosses the midline at x = pi/2 = 1.57, so point (pi/2, 0) will be on the graph. It has a peak at x=0. The vertical scale factor of 4 mean the peak is (0, 4).

Your sine tool will be able to plot the graph using these two points.

__

If you need a maximum or minimum that is to the right of the midline point, you can use the minimum at (pi, -4) = (3.14, -4).

castortr0y [4]

Answer:

Extra 4 cups to make up 11 cups a day

Step-by-step explanation:

Here we have that Jan obtains 15% of her fluid needs from food, therefore, she gets the remaining 85 % from drinking water

If the recommended daily intake = 2.7 liters  or 91.3 oz

And she already consumes 48 oz of water and  16 oz of milk

Note milk is equivalent to 0.87 water therefore total intake = 48 + 16*0.87= 61.92 oz

She needs to take additional (91.3 - 61.92) = 29.4 oz or 3.68 ≈ 4 cups extra to meet her recommended daily dosage.

Answer:

Step-by-step explanation:

Total outcome is 10 and favorable outcome is 2 ⇒ the probability that the first number is a multiple of five is \frac{2}{10} = \frac{1}{5}

Total outcome is 9 and favorable outcome is 3 ⇒ the probability that the first number is a multiple of three is \frac{1}{3} if first draw was successful, and \frac{2}{9} if the first number was multiple of three.
