Answer:
hi
Step-by-step explanation:
Here is the answer. Since the given amount $250 is compounded monthly over a 5 year period with an interest of 2.3%, here is the answer. First, we get 2.3% of $250 and the answer is $5.75. In a year, there is 12 months. 12 months times 5 years is 60 months. Now we multiply 60 by 5.75 and the answer is $345. Therefore, the present value of $250 is $595. Hope this helps.
Julio is x years old and his father is y years old:
y = 4 x
x + y ≥ 55
x + 4 x ≥ 55
An inequality is:
5 x ≥ 55
x ≥ 55 : 5
x ≥ 11
The youngest age Julio can be is 11.
X^4 + 2x^2 - 24
= (x^2 + 6)(x^2 - 4)
= (x^2 + 6)(x - 2)(x + 2)
x^4 - 9x^2 + 18
= (x^2 - 6)(x^2 - 3)
