Answer:
Step-by-step explanation:
We know that exponential formula of depreciation
where
P is the initial amount
x is the interest rate
A is the amount after t years
we are given
The annual rate of depreciation, x, on a car that was purchased for $9,000
so, P=9000
we can plug value it
we are given
when x=5 , A=4500
so, we can plug it and solve for x
so, interest rate is 13%
now, we can plug x
and we get

Answer:
X= 7/5
Step-by-step explanation:
Let's solve your equation step-by-step.
12x−15=6−3x
Step 1: Simplify both sides of the equation.
12x−15=6−3x
12x+−15=6+−3x
12x−15=−3x+6
Step 2: Add 3x to both sides.
12x−15+3x=−3x+6+3x
15x−15=6
Step 3: Add 15 to both sides.
15x−15+15=6+15
15x=21
Step 4: Divide both sides by 15.
15x
/15
=
21
/15
X= 7/5
Answer:
Step-by-step explanation:
The given trigonometric identity is .
Jana has to recall that, the cosine function is an even function.
For that matter, .
Jana has to apply this property by substituting for in the given identity to obtain,
.
Note that, the sine and the tangent functions are odd functions
You should take into account that the radius is half the diameter and the diameter is the length from the side to side of a circle.
It would be the first one because it’s the only one with the same numbers. if all the numbers and xy match then that mean there’s an infinite numbering solutions
