the function p(t)p(t)p, left parenthesis, t, right parenthesis models the average high temperature, in degrees celsius, of paity
Mnenie [13.5K]

The solution set for the last equation represents the set of all days when the towns have the same average high temperature.

  • The hotness of matter or radiation is expressed by the physical quantity known as temperature. The average air temperature for a specific time period, often a day, a month, or a year, as measured by a thermometer that has been properly exposed.
  • P(t) is the average high temperature, in degrees Celsius, of Paityn's town on t days.

       \begin{aligned} P(t)&=22.5+7.5\cos\left(\dfrac{2\pi (t-28)}{365}\right)\\\\  \end{aligned}

  • V(t) is the average high temperature, in degrees Celsius, of Vince's town on t days.

        \\ V(t)&=30.5+1.5\cos\left(\dfrac{2\pi (t-90)}{365}\right)

  • So, P(t) = V(t) represents the set of all the days when both towns have the same average high temperature.

7%of what length is 200 feet?
Aneli [31]

Step-by-step explanation:

Let the length be x

7% of x = 200ft

7/100 × x = 200

7x/100 = 200

7x = 200 × 100

7x = 20000

x = 20000/7

x = 2,857.14

How do i find the mean of a group of number's
inna [77]

Lets say your numbers are these...

10,20,30,40,50,60,70,80,90 and 100

you would add those to get 650

Now how many numbers did you add?

You added 10

so now divided

650 by 10

you get 65

that is the mean of those numbers!
