Mika placed $4200 in a savings account which compounds interest continuously at a rate of 2.3%.
How much will she have in the account after 3 years?
1st year 4200 x 1.023 = 4296.60
2nd year 4296.60 x 1.023 = 4395.4218
3rd year 4395.4218 x 1.023 = 4496.5165
Round to the nearest dollar.

F(x) = C , hope this helped !
Ni : Zn: Cu = 7:2:9 =7x : 2x : 9x
7x+2x+9x = 3.8
18x=3.8
x=3.8/18=1.9/9≈0.21
Ni: 7x=7*0.21=1.47 ≈1.5 kg
Zn: 2x=2*0.21=0.42≈0.4 kg
Cu: 9x=9*0.21=1.89 ≈1.9 kg
Check 1.5+0.4+1.9 =3.8 True
38.15 ft is the height of the tower using tangent
