Answer:
Slope = 9/6
Step-by-step explanation:
Step 1: We have formula to find the slope if we are given two point.
<h3>slope =Given points (-1, -5) and (5, 4)
Here x1 = -1, y1 = -5 and x2=5 and y2 = 4
Step 2: Plug in those values into formula and simplify.
Slope = (4 - (-5)) / (5 - (-1))
= (4 + 5)/(5 + 1) -(-5)= 5 and -(-1) = 1
Slope (m) = 9/6
Thank you.

Answer:
The time is 135 min.
Step-by-step explanation:
For this situation we are going to use Newton's Law of Cooling.
Newton’s Law of Cooling states that the rate of temperature of the body is proportional to the difference between the temperature of the body and that of the surrounding medium and is given by
where,
C = surrounding temp
= temp at any given time
t = time
= initial temp of the heated object
k = constant
From the information given we know that:
- Initial temp of the cake is 310 °F.
- The surrounding temp is 72 °F.
- After 30 minutes the cake's temperature is 220 °F.
We want to find the time, in minutes, since the cake's removal from the oven, at which its temperature will be 100°F.
To do this, first, we need to find the value of k.
Using the information given,
Next, we find the time at which the cake's temperature will be 100°F.
