Relative extrema occur where the derivative is zero (at least for your polynomial function).
So taking the derivative we get
<span>20<span>x3</span>−3<span>x2</span>+6=0
</span><span>
This is a 3rd degree equation, now if we are working with complex numbers this equation is guaranteed to have 3 solutions by the fundamental theorem of algebra. But the number of real roots are 1 which can be found out by using Descartes' rule of signs. So the maximum number of relative extrema are 1.</span>
Answer:
$960
Step-by-step explanation:
Given data
Principal=$800
rate= 4%
time= 5years
Applying the compound interest expression we have]
A=P(1+rt)
substitute
A=800(1+0.04*5)
A=800(1+0.2)
A=800*1.2
A=$960
Answer:
The rate is 
Step-by-step explanation:
The rate, in cents per minute, is given by the multiplication of the how much you paid by 100 and divided by the number of minutes.
The multiplication by 100 happens because the cost is in dollars, and each dollar has 100 cents. So
4+x=7
Move +4 to the other sign. Sign changes from +4 to -4.
4-4+x=7-4
x=3
Answer: x=3
Answer:
1332 1/4
Step-by-step explanation:
(36 1/2)² = (73/2)² = (73 * 73)/(2 * 2) = 5329/4 = 1332 1/4
