A 20,000 deposit earns 4.8 interest for 4 years . What is the final account balance if the interest is compounded semiannually ?

Bad White [126]

Answer:

Semi-annually: A = $24 178.51

Quarterly: A = $24 205.73

Monthly: A = $24 224.13

Step-by-step explanation:

The formula for compound interest is

A = P(1 + r)ⁿ

A. Compounded semi-annually

Data:

P = $20 000

APR = 4.8 %

t = 4 yr

Calculations:

n = 4 × 2 = 8

r = 0.048/2 = 0.024

A = 20 000(1+ 0.024)⁸

= 20 000 × 1.024⁸

= 20 000 × 1.208 926

= $24 178.51

B. Compounded Quarterly

n = 4 × 4 = 16

r = 0.048/4 = 0.012

A = 20 000(1+ 0.012)¹⁶

= 20 000 × 1.012¹⁶

= 20 000 × 1.210 286

= $24 205.73

C. Compounded monthly

n = 4 × 12 = 48

r = 0.048/12 = 0.004

A = 20 000(1+ 0.004)⁴⁸

= 20 000 × 1.004⁴⁸

= 20 000 × 1.211 207

= $24 224.13

Heres an ez question for yall

SSSSS [86.1K]

Answer: Choice B

$\left\{ \ 3, 5, \sqrt{34} \ \right\}$

=========================================================

Explanation:

We'll be using the converse of the pythagorean theorem.

If we had a triangle with sides a,b,c and $a^2+b^2 = c^2$ was true, then we have a right triangle. Note: c is always the longest side

For the first answer choice we have: a = 5, b = 8, c = 12

Then,

$a^2+b^2 = c^2\\\\5^2+8^2 = 12^2\\\\25+64 = 144\\\\89 = 144\\\\$

which is false. This shows that we do not have a right triangle with sides 5,8,12. This rules out choice A. Choice C is a similar story.

Choice B on the other hand works because

$a^2+b^2 = c^2\\\\3^2+5^2 = (\sqrt{34})^2\\\\9+25 = 34\\\\34 = 34\\\\$

We have a true statement at the end, which confirms choice B is a right triangle.

Traveling to Vietnam,a plane encounters a tailwind and averages 289 mph.However ,on the return trip the plane , now traveling ag

Daniel [21]

2 * plane speed in still air = 289mph + 257mph = 546
plane speed in still air = 273 mph

plane speed in still air + wind speed = 289
273 + wind speed = 289
Therefore, wind speed = 16 mph

A bus has velocity 20 m/s towards east and another bus has velocity 15 m/s in west direction. If they start to move from a point

Mashutka [201]

Answer:

The first bus has covered 2,400 m and the second bus has covered 1,800 m. They are separated by 4,200 m

Step-by-step explanation:

Constant Velocity Motion

A bun has a velocity of 20 m/s towards the east. It means it travels 20 meters each second in that direction. Assuming the east direction is positive, the distance traveled by this bus can be calculated as follows:

X1=20*t

Where t is the time in seconds.

Similarly, the distance traveled by the second bus towards the west is:

X2=-15*t

Note the negative sign because the direction points at the negative reference.

After 2 minutes = 120 seconds have passed, the distance of each bus is

X1= 20*120=2,400 m

X2=-15*120 = 1,800 m

They are separated by 2,400-(-1,800) = 4,200 m

The first bus has covered 2,400 m and the second bus has covered 1,800 m. They are separated by 4,200 m
