Answer:(X^2-5)(x^2+5)(x^4+25)
Step-by-step explanation:
Answer:
252
Step-by-step explanation:
t50 = t1 + (n - 1)(d)
= 7 + (50 - 1) (5)
= 7 + (49)(5)
= 7 + 245
= 252
Answer:![8865=6000(1+\frac{5\times t}{100})](https://tex.z-dn.net/?f=8865%3D6000%281%2B%5Cfrac%7B5%5Ctimes%20t%7D%7B100%7D%29)
Step-by-step explanation:
Given
Liam deposited ![P=\$\ 6000](https://tex.z-dn.net/?f=P%3D%5C%24%5C%206000)
Rate of interest is ![R=5\ \%](https://tex.z-dn.net/?f=R%3D5%5C%20%5C%25)
If the amount after t years is ![A=\$\ 8865](https://tex.z-dn.net/?f=A%3D%5C%24%5C%208865)
Simple interest is given by
![S.I.=\dfrac{P\times R\times t}{100}](https://tex.z-dn.net/?f=S.I.%3D%5Cdfrac%7BP%5Ctimes%20R%5Ctimes%20t%7D%7B100%7D)
And amount is
![A=P+S.I.](https://tex.z-dn.net/?f=A%3DP%2BS.I.)
![A=P(1+\frac{R\times t}{100})](https://tex.z-dn.net/?f=A%3DP%281%2B%5Cfrac%7BR%5Ctimes%20t%7D%7B100%7D%29)
Substituting values we get
![8865=6000(1+\frac{5\times t}{100})](https://tex.z-dn.net/?f=8865%3D6000%281%2B%5Cfrac%7B5%5Ctimes%20t%7D%7B100%7D%29)
![1.4775=1+\frac{5\times t}{100}](https://tex.z-dn.net/?f=1.4775%3D1%2B%5Cfrac%7B5%5Ctimes%20t%7D%7B100%7D)
![0.4775\frac{5\times t}{100}](https://tex.z-dn.net/?f=0.4775%5Cfrac%7B5%5Ctimes%20t%7D%7B100%7D)
![5t=47.75](https://tex.z-dn.net/?f=5t%3D47.75)
![t=\frac{47.75}{5}=9.55\ years](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B47.75%7D%7B5%7D%3D9.55%5C%20years)
