The answer is 12.69, you just need to put all the groceries together!!
Since in y=8, the slope is 0 (because there is no x) and b is 8 in y=mx+b, we know that the perpendicular line is x=(something) because the perpendicular lines of y=<number> are x=<number> due to that y=<number> equations are strictly horizontal while x=<number> equations are strictly vertical. Since we know that x=<number> has to pass through (7, 8), x =7
**y=x+2
when x=0,y=2; A(0,2)
when x=1,y=3; B(1,3)
**y=-x+8
when x=0,y=8; C(0,8)
when x=5,y=-3; D(5,-3)
The solution from the graph is S(2,4).
Answer:
A. 70% Decrease
Step-by-step explanation:
Before we find the percentage decrease, we need to find the difference first.
Difference = 70 - 21
= 49
Difference percentage = × 100%
= 70%
Answer:
The doomsday is 146 days
<em></em>
Step-by-step explanation:
Given
First, we calculate the solution that satisfies the initial solution
Multiply both sides by
Take integral of both sides
Integrate
To find c; let t= 0
Substitute in
Multiply through by -c
Take exponents of
i.e.
Next:
i.e. 3 months
--- initial number of breeds
So, we have:
-----------------------------------------------------------------------------
We have the growth term to be:
This implies that:
By comparison:
--- 16 rabbits after 3 months:
-----------------------------------------------------------------------------
Take -1/100th root of both sides
Recall that:
This implies that:
Make T the subject
Substitute: , and
<em>The doomsday is 146 days</em>
