Answer:
For a line perpendicular to the line with the equation of y = -x + 3, the slope would be the negative inverse of -1. So the slope is 1.
The y-intercept would be the same for the line with the equation of y = -x + 3. So the y-intercept is 3.
13/25 because I got the answer right
Answer:
A) 2/9
Step-by-step explanation:
6 rolls out of 36 would be doubles. 6/36
2 rolls out of 36 would equal 11. 2/36
6/36+2/36=8/36 = 4/18 = 2/9
Answer:
30.06 degree Celsius at 4:00 PM.
Step-by-step explanation:
We have been given that on a hot Saturday morning while people are working inside, the air conditioner keeps the temperature inside the building at 24 degrees C. At noon the air conditioner is turned off, and the people go home. The temperature outside is a constant 35 degrees C for the rest of the afternoon. The time constant for the building is 5 hr. We are asked to find the temperature inside the building at 4:00 PM.
We will use Newton's law of cooling to solve our given problem.
, where
= Temperature after t hours.
= Temperature of surrounding environment,
= Time constant.
Upon substituting our given values in Newton's cooling law, we will get:
To find the temperature at 4:00 pm, we will substitute in our formula as:
Therefore, the temperature inside building would be approximately 30.06 degree Celsius at 4:00 PM.
