It should be rational
hope it helps
Answer:
The multiplier is 0.85
The depreciation equation is;
P = I(0.85)^t
Step-by-step explanation:
Let us write an equation for the depreciation
It is in the form;
P = I( 1 - r)^t
where P is the present value
I is the value at which it was bought
r is the depreciation percentage = 15% = 15/100 = 0.15
t is the number of years after byte year it was bought
so we can have;
P = 1000(1 - 0.15)^t
P = 1000(0.85)^t
The
multiplier is 0.85
Answer:
<h2>Cubing both sides of an equation is reversible.</h2>
Step-by-step explanation:
Squaring both sides of an equation is irreversible, because the square power of negative number gives a positive result, but you can't have a negative base with a positive number, given that the square root of a negative number doesn't exist for real numbers.
In case of cubic powers, this action is reversible, because the cubic root of a negative number is also a negative number. For example
We cube both sides
If we want to reverse the equation to the beginning, we can do it, using a cubic root on each side
There you have it, cubing both sides of an equation is reversible.
The maximum number of intersections between a parabola and a line is 2.
The correct answer choice is C.2.
