If M angle 4=25 degrees, then what is M angle 8? Please help me, I need this done today, and I have tried everything
Alex73 [517]

Answer:

65 degrees

Step-by-step explanation:

The question is not complete but we can assume that m<4 and m<8 are complementary i.e they both act at right angle.

If the both act at right angle, then m<4 + m<8 = 90

Given

m<4 = 25°

Substitute into the formula

m<4 + m<8 = 90

m<8 = 90 - m<4

m<8 = 90 - 25

m< 8 = 65 degrees

Hence the measure of m<8 is 65 degrees

<em>Note that we assumed that both angles acts at right angles </em>

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
