Match each radical expression to the corresponding expression in rational exponent form

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

figure c

step-by-step explanation:

hope this .

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
