If $1000 is invested in an account earning 3% compounded monthly, how long will it take the account to grow in value to $1500? R

My name is Ann [436]

Answer:

14 months

Step-by-step explanation:

1 month) 1.03(1000) = 1030

2 months) 1030(1.03) = 1060.9

3 months) 1060.9(1.03) = 1092.727

4 months) 1092.727(1.03) = 1125.50881

5 months) 1125.50881(1.03) = 1159.2740743

6 months) 1159.2740743(1.03) = 1194.05229653

7 months) 1194.05229653(1.03) = 1229.87386542

8 months) 1229.87386542(1.03) = 1266.77008139

9 months) 1266.77008139(1.03) = 1304.77318383

10 months) 1304.77318383(1.03) = 1370.01184302

11 months) 1370.01184302(1.03) = 1411.11219831

12 months) 1411.11219831(1.03) = 1453.44556426

13 months) 1453.44556426(1.03) = 1497.04893119

14 months) 1497.04893119(1.03) = 1541.96039912

I multiplied them all by 1.03 because 0.03 is 3% but if I multiplied the numbers by 0.03 it would give me 3% of that number instead of increasing it by 3% so by doing 1.03 x the number I am adding the 3% onto the number

in a proportional relationship the ratio y/x is constant. Show that this ratio is not constant for the equation y=a-14

Colt1911 [192]

To show that the ratio $\frac{y}{x}$ is not constant for the function $y=a-14$ we only need to evaluate this function at 2 points and then show that the ratio is not the same for those two points. Note that here $a$ represents $x$ .

To find the counter examples here, I will use the values $a=20$ and $a=28$ . For $a = 20$ , the equation tells us that the output is

$y=20-14=6$ . For this value of $a$ the point is point is $(20,6)$ . The ratio $\frac{y}{x} =\frac{6}{20}$ . For the $a=28$ , $y=28-14=14$ . For this value of $a$ the point is $(28,14)$ . The ratio $\frac{y}{x} =\frac{14}{28} =\frac{1}{2}$ . Clearly this ratio is not constant for all ordered pairs.
