Julia invested $4,000.00 in a mutual fund with the simple interest rate of 3.5% per year. how much interest would she earn after 2 years

280$

Step-by-step explanation: Using the I=prt method.

P=Amount Borrowed or Invested

R=Interest Rate

T= Years

P=$4000.00

R=%3.5>>0.035

T=2 years

4000*0.035*2=280

$280

take it another

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
