Answer:
20x5=100
Step-by-step explanation:
$20 a year for 5 years is 20x5. 20x5=100
To answer the question, I assume that the interest (i) is compounded. To solve for the future worth (F) of the present investment (P) is calculated by the equation,
F = P x (1 + i)^n
where n is the number of years. Substituting the known values,
F = ($2000) x (1 + 0.025)^3 = $2,153.78
Thus, the answer is approximately $2,153.8.
Answer:
4+16=0
4=−16=162
2=±4
Case 1 2=+4
=±2√
√=±(12√+12√)
=±2‾√+2‾√
Case 2 2=−4=43
=±23/2=±2()1/2
∵√=±(12√+12√)
=±(2‾√+2‾√)
So in all,
=2‾√+2‾√
=−2‾√+2‾√
=2‾√−2‾√
=−2‾√−2‾√
Let √=+
Squaring both sides, we have
=(+)2
0+1=2−2+2⟹
2−2=0(1)
2=1
=12
Plugging in (1) … ⟹
2−1(2)2=0
4=14
2=12
∴=±12‾√
∴=±12‾√
∴√=+=±(12+12)
This can also be shown as below
√=12+12
Or
√=−12−12 \
