Answer: ![3^{\circ}C](https://tex.z-dn.net/?f=3%5E%7B%5Ccirc%7DC)
Step-by-step explanation:
Given
The temperature on Monday was ![-5^{\circ}C](https://tex.z-dn.net/?f=-5%5E%7B%5Ccirc%7DC)
By Tuesday, it becomes ![-2^{\circ}C](https://tex.z-dn.net/?f=-2%5E%7B%5Ccirc%7DC)
Change in temperature is the difference between the two temperatures.
![\Rightarrow \Delta T=-2-(-5)\\\Rightarrow \Delta T=-2+5\\\Rightarrow \Delta T=3^{\circ}C](https://tex.z-dn.net/?f=%5CRightarrow%20%5CDelta%20T%3D-2-%28-5%29%5C%5C%5CRightarrow%20%5CDelta%20T%3D-2%2B5%5C%5C%5CRightarrow%20%5CDelta%20T%3D3%5E%7B%5Ccirc%7DC)
Therefore, the change in temperature is
.
It’s D(15)
(3)*3+(2)*3
9+6=15
The answer would be 56.10
