Answer: 0.38065
in simpler terms x=± 0.145 =±0.38065
Step-by-step explanation: -490x2+71 = 0
Subtract 71 from both sides of the equation :
-490x2 = -71
Multiply both sides of the equation by (-1) : 490x2 = 71
Divide both sides of the equation by 490:
x2 = 71/490 = 0.145
When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:
x = ± √ 71/490
The equation has two real solutions
These solutions are x = ±√ 0.145 = ± 0.38065
Answer:
$0.63
Step-by-step explanation:
Raoul saves $14.50 each month for 3 months. Total amount saved is 14.50 * 3 = $43.50
He earned an interest of $0.33.
The total amount of money he has is thus: 43.50 + 0.33 = $43.83
Hector puts $3.60 each week for 12 weeks. Total amount save by Hector is thus 3.60 * 12 = $43.2
Now we are asked to get how much money Raoul has. To get this, we simply subtract the amount of money Hector has from that of Raoul
That would be 43.83 - 43.2 = $0.63
