The temperature would be -7 degrees
romanna [79]2 years ago

Answer:

-7

Step-by-step explanation:

First determine the number of hours that have past from 10PM to 1 AM

10PM to 11 PM is 1 Hour

11PM to 12 AM is 1 Hour

12AM to 1 AM is 1 hour

for a total of 3 hours

Next multiply the average number of degrees the temperature is rising by the number of hours that passed

3 x 3 =9 which is the total number of degrees the temperature has risen by.

Now add 9 to -16

-16 + 9 = -7

Waves with an amplitude of 2 feet pass a dock every 30 seconds. Write an equation for a cosine function to model the height of a
kolbaska11 [484]

Answer:

The cosine function to model the height of a water particle above and below the mean water line is h = 2·cos((π/30)·t)

Step-by-step explanation:

The cosine function equation is given as follows h = d + a·cos(b(x - c))

Where:

\left | a \right | = Amplitude

2·π/b = The period

c = The phase shift

d = The vertical shift

h = Height of the function

x = The time duration of motion of the wave, t

The given data are;

The amplitude \left | a \right | = 2 feet

Time for the wave to pass the dock

The number of times the wave passes a point in each cycle = 2 times

Therefore;

The time for each complete cycle = 2 × 30 seconds  = 60 seconds

The time for each complete cycle = Period = 2·π/b = 60

b = π/30 =

Taking the phase shift as zero, (moving wave) and the vertical shift as zero (movement about the mean water line), we have

h = 0 + 2·cos(π/30(t - 0)) = 2·cos((π/30)·t)

The cosine function is h = 2·cos((π/30)·t).

VikaD [51]

Answer:

A) 3/50

Step-by-step explanation:

2 + 5 + 3 = 10

Probability of drawing red = 2/10 = 1/5

Probability of drawing blue = 3/10

\frac{1}{5} *\frac{3}{10}

3/50
