Step-by-step explanation:
Pick two points on the line and determine their coordinates
Select one to be (x1, y1) and the other to be (x2, y2)
Finally use the slope intersect equation to calculate the slope:
<em>Formula-</em><em> </em>
<em>y = mx + b </em>
<em></em>

60%; Since 1/5 is .2 or 20% and then multiply that by 3.
I think it would be $14 per book
7978 years
Step-by-step explanation:
A = A02^(-t/hl)
where hl = half-life.
Dividing both sides by A0 and taking the logarithm, we get
ln(A/A0) = -(t/hl)ln2
or solving for t,
t= -(hl)ln(A/A0)/ln2
note that A/A0 = 0.38
t = -(5715 yrs)[ln(0.38)/ln2]
= 7978 years
Answer:
3/2
Step-by-step explanation:
Recall that slope is y2 - y1 / x2 - x1.
Excellent. The question provides us with two points: (2,4) and (0,1). We can insert these two points into our equation.
Slope = (4 - 1) / (2 - 0) = 3 / 2.
Hope this helps!
