Answer:
73.5%
Step-by-step explanation:
The question is incomplete, the complete question is shown in the image attached.
Half life (t1/2) = 9 days
Time taken (t) = 4 days
From;
0.693/t1/2 = 2.303/t log (No/N)
Substituting values;
0.693/9 = 2.303/4 log(No/N)
0.693/9 × 4/2.303= log(No/N)
2.772/20.727= log(No/N)
Antilog (2.772/20.727)=No/N
1.36 = No/N
Therefore;
N/No = (1.36)^-1
N/No = 0.735
Percentage remaining after 4 days= 0.735× 100= 73.5%
is the equation best represents the line.
Solution:
Take any two points on the line.
Let the points be (0, –4) and (4, 7).
General form of equation of a line is y = mx + c
where m is the slope and c is the y-intercept of the line.
<em>y-intercept is the point which line crosses at y-axis.</em>
In the given line, y-intercept is 4.
c = 4
Slope of the line:
Equation of the line:
y = mx + c
Hence is the equation best represents the line.
Answer:
In y-intercept form: X = 5
Step-by-step explanation:
Becuz the slope is Undefined
