Answer:
y= x+1
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Gradient of line =
Using the above formula,
Gradient
Thus m=1. Substitute m=1 into the equation:
y= 1x +c
y= x +c
Susbt. a coordinate.
When x=3, y=4,
4= 3 +c
c= 4-3
c=1
Thus, the equation of the line is y= x+1.
Answer:
The graph is shown below.
The time to make the taste to half is <u>4.265 s.</u>
Step-by-step explanation:
Given:
Initial value of the taste is,
Therefore, the quality of taste over time 't' is given as:
Now, when the taste reduces to half,
Therefore,
Taking natural log on both the sides, we get:
Therefore, the time to make the taste to half is <u>4.265 s.</u>
