Answer:
Initial deposit P = 4,801 (Approx.)
Step-by-step explanation:
Given:
Amount after 4 year = 5,300
Number of year = 4 year
Rate = 2.5% = 0.025
Find:
Initial deposit
Computation:
A = P[1+r]ⁿ
5,300 = P[1+0.025]⁴
5,300 = P[1.025]⁴
5,300 = P[1.1038]
Initial deposit P = 4,801 (Approx.)
36 30%
____ = _____
x 100%
Cross multiply and divide
x=120
There are 30 men. the way to check this is my dividing 36/6 and you get 6.
F(x) = 9x² - 54x - 19 = 9x² - 57x + 3x - 19 = 3x(3x - 19) + 1(3x - 19)
= (3x - 19)(3x + 1)
f(x) = 0 if 3x - 19 =0 or 3x + 1 = 0
3x = 19 or 3x = -1
x = 19/3 or x = -1/3
