Suppose you invest $78 a month in an annuity that earns a 2.8% APR, compounded monthly. How much money will you have in this acc

Alecsey [184]

Answer:

$87.23.

Step-by-step explanation:

We are asked to find the amount after 4 years compounded monthly at the rate of 2.8% APR.

We will use compound interest formula to solve our given problem.

$A=P(1+\frac{r}{n})^nT$ , where,

A = Final amount after T years,

P = Principal amount,

r = Interest rate in decimal form,

n = Number of times interest is compounded per year.

T = Time in years.

Let us convert our given rate in decimal form.

$2.8\%=\frac{2.8}{100}=0.028$

Upon substituting our given values in compound interest formula we will get,

$A=78(1+\frac{0.028}{12})^{12*4}$

$A=78(1+0.002333)^{48}$

$A=78(1.002333)^{48}$

$A=78*1.1183669447674708747$

$A=87.2326216918627282266\approx 87.23$

Therefore, we will have $87.23 in the account after 4 years.

Find the resultant force

Assoli18 [71]

951 1404 393

Answer:

61.03 N at 35° above the horizontal

Step-by-step explanation:

The forces operate at right angles, so the Pythagorean theorem can be used to find the magnitude of the resultant:

||F1 +F2|| = √(50² +35²) = √3725 ≈ 61.03 . . . . newtons

The angle (α) relative to F2 can be found using the tangent relation.

tan(α) = 50/35

α = arctan(50/35) ≈ 55.008°

Then the angle relative to the horizontal reference line is ...

55.0° -20° = 35.0°

The resultant is about 61.03 N at an angle of 35° above the horizontal.

Dean won a trip to the upcoming Winter Olympics and needs to plan which events to attend. During the first week of competition,

zlopas [31]

Answer:

6 different orders

Step-by-step explanation:

Given:

Number of events taking place = 3 (Speed skating, ice hockey and cross-country skiing)

Now, Dean plans to attend ne round from each one of them.

The questions asks us to find the different orders in which Dean can attend each event.

So, this is a question of permutations as order of events is important here.

So, number of ways to attend 1 event out of 3 events is 3.

Now, there are 2 events left. Number of ways of attending 1 event out of the remaining two events is 2 ways.

Now, only one event will be left. So, Dean will finally attend that event.

Thus, total number of different orders in which Dean can attend one round of all the 3 events is given as:

$=3\times2\times 1\\=6$

Hence, Dean can attend each of the three events in 6 different orders.
