Answer:
yes
Step-by-step explanation:
By the "rule of 72", the amount will be doubled in 72/I years, where I is the annual interest rate in percent. That is, it can be estimated to take 72/4 = 18 years to double the $240 investment to $480. It would take another 18 years to double it again to $960. So, to achieve a balance of $1500 will be expected to take more than 36 years. The only reasonable answer choice is the one you have selected.
__
The exact solution is ...
log (1500/240)/log(1 +0.04) ≈ 46.72 years ≈ 47 years.
Answer:
A)
B)
C)
D)
Step-by-step explanation:
Let's go through each answer choice.
A) -3 is to the right of -4.5 on the number line, so it is greater than -4.5
B) -3/2 is to the right of -4.5 on the number line, so it is greater than -4.5
C) 1/3 is to the right of -4.5 on the number line, so it is greater than -4.5
D) 2.5 is to the right of -4.5 on the number line, so it is greater than -4.5
E) -5.2 is to the left of -4.5 on the number line, so it is less than -4.5
Therefore, the answers are A), B), C), and D).
Answer:
(x-5)*(x+5)
Step-by-step explanation:
= x^2 + 5x - 25 - 5x
= x^2 +5x - 5x -25
because +5x - 5x = 0 so
= x^2 + 0 - 25
= x^2 - 25
25 can be written as 5^2
= x^2 - 5^2
we know that a^2 - b^2 = (a-b) * (a+b)
so x^2 - 5^2
= (x-5) * (x+5)
