The zero for -2x+10x-16 is positive 2
Answer:
A.
Step-by-step explanation:
you have to find the discriminant
b²-4ac for each equation
if discriminant < 0 no real solutions because will be negative under the squareroot whhan you try to find the roots
if discriminant = 0 there is only one solution
if discriminant > 0 two real solutions
for your given problems
A. discriminant =(-2)²-4*2*15 will be negative
1) $600 deposited at 4% simple interest for one year generates:
$600 * 4% = $600 * 0040 = $24
2) If he wants to earn $132 in interest for the year, he yet needs to generate $132 - $24 = $108 (additional)
3) The interest rate to generate $108 on a deposit of $1200 in a year, at simple interest is:
$1200 * (r) = $108 => r = 108 / 1200 = 0.09 = 9/100 = 9%
Answer: 9%
Answer:
That's incorrect. He wrote the form for fifty-two and sixty-six thousandths. The correct number is 52.66.
