1. You have the following quadratic equation and to solve it, you must follow the steps below:
<span>
x</span>²<span>+3=9x
2. The form of the equation that you need to apply the quadratic formula, is:
ax</span>²+bx+c=0
<span>
3. Then:
</span>
x²<span>+3=9x
</span> x²-9x<span>+3=0
</span><span>
4. The quadratic formula is shown below:
x=(-b±√(b^2-4ac))/2a
5. Then, you have:
a=1
b=-9
c=3
6. When you substitute the values into the quadratic formula, you obtain:
x1=0.34
x2=8.65</span>
C) Always anything more you want to know?
Answer:
The rate of change with respect to monthly sales is 4000 - 200t.
Step-by-step explanation:
The sales per month (monthly sales) of the new sound system being sold by Sunny Electronics is given by q(t) = 4000t - 100
units per month, where t is number of months from the introduction of the sound system.
The price of each unit of the sound system charged by Sunny Electronics is given by p(t) = 2000 -
.
The rate of change with respect to monthly sales will be given by the equation
.
