Answer:
$7420
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 2%/100 = 0.02 per year,
then, solving our equation
I = 7000 × 0.02 × 3 = 420
I = $ 420.00
The simple interest accumulated
on a principal of $ 7,000.00
at a rate of 2% per year
for 3 years is $ 420.00.
b=-8
9+1/4b=7
-2=1/4b
±1, ±2, and ±4
4x² + bx + c = (Ax + B) (Cx + D)
Distribute:
4x² + bx + c = ACx² + (AD + BC) x + BD
Matching the coefficients, AC = 4. So A must be a factor of 4. Possible values of A are therefore ±1, ±2, and ±4.
Sqrt 26 = 5.1
Sqrt [(1-6)^2 + (3-2)^2]
= sqrt (25+1) = sqrt 26 = 5.1
