3 is the answer because you subtract 2 from each side and devide by 5
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:
4.08
Step-by-step explanation:
26.08 +(-6)²*(3.4-8.9)÷9
parenthesis first
26.08+36*(-5.5)÷9
then multiplication
26.08-198÷9
division
26.08-22
addition or subtraction
4.08
Answer:
Step-by-step explanation:
its A
Answer:
1. An Experimental
2. Dependent
3. Independent
Step-by-step explanation:
Considering the description of how the research was carried out, it can be concluded that This study is an example of AN EXPERIMENTAL study. This because the researcher is trying to study the effectiveness of a new drug for lowering cholesterol
The difference in cholesterol level is the DEPENDENT variable. This is because the difference in cholesterol level is what the researcher wants to determine.
The treatment with a drug or placebo is the INDEPENDENT variable. This is because this is what the researcher manipulates to determine the difference in cholesterol level which is the dependent variable in this experimental study.
