Approximately there are some of these on the we
This looks like scalar matrix multiplication. The idea here is to multiply the scalar 3 by each item inside the matrix.
Doing so leads to the answer [3 -12 15 -21]
Side note: I'm assuming the matrix given to you has 1 row and 4 columns.
I’m confused what do we have to do with the promblem do we Evaluate the function or..... if u evaluate the function the answe is 2x +10= x= 10=18x =
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.
