Answer:
Step-by-step explanation:
Hi!
Lets call:
T = temprature of the object
T₀ = temperature of surroundings
t = time
The rate of change of T is its derivative with respecto to time. If T > T₀, the object looses heat, so T decreases. Then, being k > 0:
In this case T₀ = 70ºF and k = 0.05/min. Then the differential equation is:
Answer:
Step-by-step explanation:
I am joyous to assist you anytime.
Answer:
angle B is angle M
Look at the position.
Or the name of figures
(PMNO) and (ABCD) ,M and B are the second.
Given:
Steven wrote this equation:
To find:
The error in Steven's reasoning and then find the correct product.
Solution:
We have,
This statement is incorrect because we cannot write product directly as Steven wrote.
We need to multiply the place values of each digit of first number with the place values of second number and then we need to add the resulted values.
Therefore, the correct product is 72.
