The answer to the problem I think is a>-4.
You have to flip it if it is a negative. I could be wrong..
Answer:
Option 1 and option 5.
Step-by-step explanation:
The given graph is a downward parabola. It means the value of function increases and after reaching its maximum point the value of function decreases.
Scenario 1 : The height of a stone shot by a catapult reaches a maximum height and then falls on the ground.
The graph of this scenario is a downward parabola. Therefore option 1 is correct.
Scenario 2 : The speed of a car increases constantly by 10 miles per hour.
The graph of this scenario is a straight line with slope 10. Therefore option 2 is incorrect.
Scenario 3 : The radioactivity of a substance decreases by 10% every year.
The graph of this scenario is an decreasing curve which represents an exponential function. Therefore option 3 is incorrect.
Scenario 4 : The amount of money in an account decreases for a few months and then increases.
The graph of this scenario is a upward parabola. Therefore option 4 is incorrect.
Scenario 5 : The sale of product increases at first and then decreases.
The graph of this scenario is a downward parabola. Therefore option 5 is correct.
Therefore, the correct options are 1 and 5.
Answer:
48
Step-by-step explanation:
For the answer to the question above, asking to d<span>etermine the finance charge on a $6,500 loan with an interest rate of 9.5% compounded monthly over 36 months.</span>
6500( 1+ 0.95/36)^1
6500 (1+0.0263888888888889)
6500(1.0263888888888889)
=6671.527777777778
Now deduct that to the original FV
6671.53-6500=
The answer is
171. 53 is the interest
i hope my answer helped you.
To solve this equation, we have to use the distributive property to multiply 5y through the parentheses.
-45y - 15y^2 = 13
-15y^2 - 45y - 13 = 0
15y^2-45y-13=0
<span>y=<span><span>32</span>+<span><span><span><span>130</span><span>√2805</span></span><span> or </span></span>y</span></span></span>=<span><span>32</span><span><span><span>−1</span>30</span><span>√<span>2805, when you use the quadratic formula.</span></span></span></span>
