Answer:
ED = 3.2 cm
Step-by-step explanation:
According to chord-chord power theorem,
(AE)(EB) = (CE)(ED)
2*4 = 2.5 *ED
8/2.5 = ED
ED = 3.2 cm
<span>Interest = Principle * rate * time
I = PRT
</span><span>P = 1000
R = 2.5% -- change to a decimal = .025
T = 3
</span>
<span>
now we sub
I = PRT
I = (1000)(.025)(3)
I = 75
so at the end of 3 years, there will be : 1000 + 75 = $ 1075 in the account</span>
Y is being multiplied by 0.6 so you have to divide by 0.6 on both sides to leave y alone.
y=10.3/0.6
