Answer:
No complex roots; 3 real roots
Step-by-step explanation:
If a third order polynomial has any complex roots, then as a rule it has 1 real root and 2 complex roots. In this particular case, the polynomial has three real roots, as can be determined by graphing the function. The graph crosses the x-axis in 3 places.
For this case we have:
By trigonometric property we have:
Where:
Substituting:
Clearing x we have:
Thus, the equation is:
Answer:
Answer:
45.95x + 30.50
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
Matt's Mechanics charges $45.95 per hour to do a car repairs plus $30.50 for waste disposal.
<em>45.95x + 30.50</em>

Answer: 45.95x + 30.50
Product means multiplication.
0.6 * 7 = 4.2
I’m pretty sure it’s h because the lines meet in the x axis
