10 times 11% is 11 dollars, so 11 times 10 equals 110. Then 110 plus 100 equals 210. So you'd have $210 after ten years with 11 percent interest.
To solve using completing square method we proceed as follows:
x^2-10x+8=0
x^2-10x=-8
but
c=(b/2)^2
c=(10/2)^2=25
thus we can add this in our expression to get
x^2-10x+25=8+25
factorizing the LHS we get:
(x-5)(x-5)=33
(x-5)^2=33
getting the square roots of both sides we have:
x-5=+/-√33
x=5+/-√33

Answer:
0.004 km; 400 cm; 4000 mm
Step-by-step explanation:
1 km = 1000 m
1 = (1 km)/(1000 m)
4 m * (1 km)/(1000 m) = 4/1000 km = 0.004 km
1 m = 100 cm
1 = (100 cm)/(1 m)
4 m * (100 cm)/(1 m) = 400 cm
1 m = 1000 mm
1 = (1000 mm)/(1 m)
4 m * (1000 mm)/(1 m) = 4000 mm
Answer: 0.004 km; 400 cm; 4000 mm
