Newton’s Law of Cooling expresses the relationship between the temperature of a cooling object y and the time t elapsed since co
True [87]

Answer:

79 °F

Step-by-step explanation:

Newton’s Law of Cooling:

y = ae^{-kt} + c

Data

  • The initial temperature of a liquid is 160 °F
  • The temperature in the room (c) is 76 °F
  • Then a = 160 - 76 = 84 °F
  • k = 0.23
  • t = 15 minutes

Replacing into the equation:

y = 84e^{-0.23 \times 15} + 76

y = 79 °F

I NEED HELP PLEASE, THANKS! :)
natka813 [3]

Answer:

Step-by-step explanation:

Cos θ =<u> u*v     </u>

             IuI *IvI

u * v = 7*(-1) + (-2)*2

       = -7 - 4

      = -11

IuI = \sqrt{7^{2}+(-2)^{2}}\\

    = \sqrt{49+4}\\\\

    = \sqrt{53}

I vI = \sqrt{(-1)^{2}+2^{2}}\\

     = \sqrt{1+4}\\\\

      = \sqrt{5}\\

Cos θ = \frac{-11}{\sqrt{53}*\sqrt{5} } \\\\

          = \frac{-11}{16.28}\\\\

   Cos θ = -0.68

θ = 132.5°

How do you determine if the graph opens<br> up or opens down?
strojnjashka [21]

Answer:

There is an easy way to tell whether the graph of a quadratic function opens upward or downward: if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward.
