Answer:
I graphed it in the pic below
Step-by-step explanation:
The first one is in green and the second in red
+4 and +6 is where the line intercepts the y axis
-4x and -2x are the slopes.
Its 16.5 m^2
if i am wrong i am sorry
i am not the best at math
Answer:
The equations of both cups after t minutes is given by:
Step-by-step explanation:
The complete exercise says:
Two cups of coffee are poured from the same pot. The initial temperature of the coffee is 180°F, and is 0.2337 (for time in minutes).
Newton's law of cooling:
where,
= room temperature
= initial temperature
k=cooling constant
Hence,
<u>Cup 1:</u>
= 75 °F
= 180 °F
<u>Cup 2:</u>
= 75 °F
= 162 °F
Answer:
x= 0
Step-by-step explanation:
Let's form an equation using the slope of the line.
☆ (x₁, y₁) is the 1st coordinate and (x₂, y₂) is the 2nd coordinate
Let the gradient of line be m.
The product of the gradients of 2 perpendicular lines is -1.
m(⅓)= -1
m= -1 ×3
m= -3
x= -1 +1
x= 0
