Zinaida [17]

Answer: $ 2388.10

Step-by-step explanation:

Given: Principal value : P= $2,000

annual rate : r= 3% = 0.03

Time : t= 6 years

Formula to calculate the accumulated amount if compounded continuously :-

A=P(1+r)^t

A=2000(1+0.03)^6\\\\=2000(1.03)^6\\\\=2000(1.1940523)\\\\=2388.10

Hence, Money in Katie's account after 6 years = $ 2388.10

length of a rectangle is 3 times its width.If its perimeter is 24 centimetres what is the area of the rectangle?​
fgiga [73]

Answer:

<h3>27 cm²</h3>

Step-by-step explanation:

The length is 3 × width.

l = 3w

The perimeter is 24 centimeters.

P = 2l + 2w

24 = 2(3w) + 2w

24 = 6w + 2w

24 = 8w

3 = w

The width is 3 centimeters.

l = 3(3)

l = 9

The length is 9 centimeters.

Area is l × w.

A = l × w

A = 9 × 3

A = 27

The area is 27 squared centimeters.

Why does demand equal marginal revenue for perfectly competitive firms
shepuryov [24]
Specifically, price only equals marginal revenue in perfect competition. Price equals MR in perfect competition because your demand curve is horizontal. No matter how much you produce, it always sells at the same price. In other market structures, you can raise or lower prices.

Please explain how to do and set up
In-s [12.5K]

A

using the Cosine rule in ΔSTU

let t = SU, s = TU and u = ST, then

t² = u² + s² - (2us cos T )

substitute the appropriate values into the formula

t² = 5² + 9² - (2 × 5 × 9 × cos68° )

   = 25 + 81 - 90cos68°

   = 106 - 33.71 = 72.29

⇒ t = \sqrt{72.29} ≈ 8.5 in → A
