The future worth (F) of the current investment (P) with the compounded interest of i is calculated through the formula,
F = P x (1 + i)^n
Substituting the known values and the given values,
y = 360(1 + 0.03)^x
Simplifying,
y = 360(1.03)^x
Thus, the answer is letter D.
Answer:
65 dm and 52 dm
Step-by-step explanation:
If the scale factor of the sides is k, then the scale factor of the areas is k^2.
The scale factor of the areas is (32 dm^2)/(50 dm^2) = 0.64 = k^2
The scale factor of the sides is k = \sqrt(0.64) = 0.8
The perimeters are in a ratio of 1:0.8
x + 0.8x = 117
1.8x = 117
x = 65
0.8x = 0.8(65) = 52
The perimeters are 65 dm and 52 dm.
