Answer:

  k ≈ -0.06729

Step-by-step explanation:

The initial temperature difference is 85 -36 = 49 degrees. After 5 minutes, the temperature difference is 71 -36 = 35 degrees. The constant k is the natural log of the ratio of these temperature differences, divided by the time unit.

  k = ln(35/49)/5 ≈ -0.06729

__

The equation for the temperature T of the can in the refrigerator is ...

  T = 49e^(-0.06729t) +36

_____

<em>Additional comment</em>

Be careful with the sign. If you're filling in k in e^(-kt), then the sign of k will be positive. Above, we have taken the form of the exponential term to be e^(kt), so k is negative.

A figure is located at (2, 0), (2, -3), and (5, 0) on a coordinate plane. What kind of 3-D shape would be created if the figure
expeople1 [14]

When the shape is rotated around the x-axis, a 3-D shape would be formed

The 3-D shape is a tetrahedron with radius 2 and height 4

<h3>How to determine the 3-D shape?</h3>

The coordinates of the figure are given as:

(2, 0), (2, −3), and (5, 0)

The above coordinates represent a triangle that has one of its sides on the x-axis.

So, when the shape is rotated across the axis, the other two lines would make a diagonal the side on the x-axis.

This movement would form a tetrahedron with the following dimensions

  • Height = Distance (2, 0) and (5, 0) i.e. 3 units
  • Radius = Distance (2, 0) and (2, −3) i.e. 3 units

Hence, the 3-D shape is a tetrahedron with radius 3 and height 3
