For this, the first thing to do is to assume that the function of temperature with respect to r is written in one of the following ways:
Way 1:
Way 2:
To find the instant variation we must find the derivative of the temperature with respect to the distance r.
We have then:
For function 1:
Rewriting
For function 2:
Rewriting
Answer:
The instantaneous variation of the temperature with respect to r is given by:
Assuming function 1:
Assuming Function 2:
Answer:
The total number of couples attending the banquet was 52.
Step-by-step explanation:
Given that a school reserved a banquet hall for the spring dance, and that, in addition to a $ 100 deposit, each couple must pay $ 20, to determine the total number of couples attending if the total cost of the banquet hall was $ 1,140 is due perform the following calculation:
100 + (20 x X) = 1140
20X = 1140 - 100
X = 1040/20
X = 52
Thus, the total number of couples attending the banquet was 52.
Answer:
<h2>
</h2>
Option D is the correct option.
Step-by-step explanation:
Given,
A ( 4, 5 ) , B ( 2 , 2 ) , C ( 4 , 2 )
Let,
A ( 4 , 5 ) → ( x1 , y1 )
B ( 2 , 2 ) → ( x2 , y2 )
Now, finding the length of AB
Use the distance formula to find the length of AB
plug the values
Calculate the difference
Evaluate the power
Add the numbers
Hope this helps..
Best regards!!
Do 21/100, which is the fraction....
