You invest $2,000 in an account that is compounded annually at an interest rate of 5%. You never withdraw money from the account. Which equation below gives the amount of money you will have in the account after t years?A(t) = 2,000e5t
A(t) = 2,000e0.05t
A(t) = 2,000(1.5)t
A(t) = 2,000(1.05)t

Answers

Answer 1

Answer: The formula is: A ( t ) = I * ( 1 + r )^t. In this case: I = $2,000, r = 0.05 ( or%5) and t is the number of years. A ( t ) = 2,000 * ( 1 + 0.05 ) ^t ; A ( t ) = 2,000 * ( 1.05 )^t. For example: after 1 year: A ( 1 ) = 2,000 * ( 1.05 )^1 = $2,100 and after 2 years: A ( 2 ) = 2,000 * ( 1.05 )^2 = $2,205, and so on. Answer: D ) A ( t ) = 2,000 * ( 1.05 )^t

Answer 2

Answer:

Answer: D: A(t)= 2,000 (1.05) ^t

hancock building dimensions. the top of the john handcock building in Chicago is a rectangle whose length is 60ft more than width. the perimeter is 520 ft. find the width and the length of the rectangle. find the area of the rectangle.

Answers

Rectangle shape.
Length = x + 60 ft
Width = x
Perimeter = 520

Perimeter = 2(L+W)
520 = 2(x+60) + 2(x)
520 = 2x + 120 + 2x
520 = 4x + 120
520 - 120 = 4x
400 = 4x
400/4 = x
100 = x

Length = x + 60 = 100 + 60 = 160 ft
Width = x = 100 ft

Area = Length * Width
A = 160ft * 100ft
A = 16,000 ft²

If A and B are independent events, P(A and B) =

Answers

Answer:

If A and B are independent events, then the events A and B' are also independent. Proof: The events A and B are independent, so, P(A ∩ B) = P(A) P(B). From the Venn diagram, we see that the events A ∩ B and A ∩ B' are mutually exclusive and together they form the event A.

Answer:

Step-by-step explanation:

Given A and B are independent events, P(A and B) = P(A)*P(B)
