What is amount of interest I earned on $4,000 deposited in a savings account with 4% interest compounded annually after 4 years?
amid [387]

Answer:

$ 679.43

Step-by-step explanation:

Since, the amount formula in compound interest is,

A=P(1+\frac{r}{n})^{nt}

Where,

P = initial amount,

r = annual rate of interest,

n = number of compounding periods in a year,

t = number of years,

Here, P = $ 4,000, r = 4% = 0.04, t = 4 years, n = 1,

So, the amount after 4 years would be,

=4000(1+0.04)^4\approx \$4679.43

Hence, the amount of interest,

I=A-P=4679.43-4000 = \$ 679.43

An airplane is flying in a direction of 75° north of east at a constant flight speed of 300 miles per hour. The wind is blowing
Nutka1998 [239]

Answer:

79.7°

Step-by-step explanation:

We resolve the speed of the plane into horizontal and vertical components respectively as 300cos75° and 300sin75° respectively. Since the wind blows due west at a speed of 25 miles per hour, its direction is horizontal and is given by 25cos180° = -25 mph.  We now add both horizontal components to get the resultant horizontal component of the airplane's speed.

So 300cos75° mph + (-25 mph) = 77.646 - 25 = 52.646 mph.

The vertical component of its speed is 300sin75° since that's the only horizontal motion of the airplane. So the resultant vertical component of the airplane's speed is 300sin75° = 289.778 mph

The direction of the plane, Ф = tan⁻¹(vertical component of speed/horizontal component of speed)

Ф = tan⁻¹(289.778 mph/52.646 mph)

Ф = tan⁻¹(5.5043)

Ф = 79.7°
