Decay every two years over a period of t years:
Fourth option: f(t)=(0.75)^(t/2)
decay 2 times a year over a period of t years:
Second option: f(t)=(0.9306)^(2t)
Sixth option: f(t)=(0.8660)^(2t)
decay once per year over a period of t years:
First option: f(t)=(0.9306)^t
Third option: f(t)=(0.8660)^t
Answer:
Down there! Idk if it was what your looking for but this is what I got..
Step-by-step explanation:
(-∞,∞)
Step-by-step explanation:
PART A:
given
This is true for all values of x.
So,x∈-∞,+∞
PART B:
When ,left hand side=
right hand side=
so,left hand side =right hand side
When ,left hand side=
right hand side=
so,left hand side =right hand side
When ,left hand side=
right hand side=
so,left hand side =right hand side
Coordinates of the point that partitions the line into the given ratio is; (1, 5)
<h3>How to divide a line segment?</h3>
If the ratio dividing a line segment represents a:b, then the formula to divide the line segment is;
Coordinates = {(bx₁ + ax₂)/(a + b), (by₁ + ay₂)/(a + b)}
From our question, we have the ratio as;
1:2. Thus; a = 1 and b = 2
Our coordinate of CD is; C(-1,7) and D(5, 1)
Thus;
x₁ = -1
x₂ = 5
y₁ = 7
y₂ = 1
Coordinates of the point that partitions the line into the given ratio is;
Coordinate = {(2*-1 + 1*5)/(1 + 2), (2*7 + 1*1)/(1 + 2)}
Coordinate = (3/3, 15/3) = (1, 5)
