The amount of money, in dollars, in an account after t years is given by A = 1000(1.03)t. The initial deposit into the account w

nadezda [96]

<span>Given
A = 1000(1.03)t

With the above equation, the initial deposit is $1000 and the interest rate on said deposit is 3%.

I am assuming that the above equation is a compounding interest where t is an exponent. t represents time period in years.

Let us assume t is 5.

A = 1,000(1.03)^5 = 1,000(1.159) = 1,159.00

After 5 years, the $1,000 deposit will earn an interest of $159 for a total of $1,159.</span>

Which mathematical property is demonstrated? if x= -3 and -3 =z,then x=z

Vladimir79 [104]

Basic Properties of Real Numbers:

Given that X, Y, Z, A, B, C, and D are real numbers, then the following are true:

Commutative Property of Addition: X+Y = Y+X

Commutative Property of Multiplication: XY = YX

Associative Property of Addition: (X+Y) + Z = X + (Y + Z)

Associative Property of Multiplication: ( X Y ) Z = X ( Y Z )

Additive Identity: For any real number X, X+0 = X where 0 is the additive identity

Additive Inverse: For any real number X, there exists -X such that X+(-X) = 0

Multiplicative Identity: For any real number X, 1●X = X where 1 is the multiplicative identity

Multiplicative Inverse: For any real number X where X≠0, there exists 1/X such that X ●(1/X) = 1

Zero Product Law: If XY = 0, then X=0 or Y=0 or both X and Y = 0

Ted invests $8,310 in a savings account with a fixed annual interest rate of 2% compounded continuously. How long will it take f

Vsevolod [243]

Answer: It will take 8 years.

Step-by-step explanation:

Equation for interest compounded continuously:

$A=Pe^{rt}$ , A = accumulated amount , P=Principal value , r =rate of interest , t= time.

Given: P= $8,310 , r = 2% , A= $9,751.88

$9751.88=8310e^{0.02t}\\\\\Rightarrow\ \dfrac{9751.88}{8310}=e^{0.02t}\\\\\Rightarrow\ 1.17351143201=e^{0.02t}$

Taking natural log on both sides

$\ln (1.17351143201)=\ln (e^{0.02t})\\\\\Rightarrow\ 0.160000478068=0.02t\\\\\Rightarrow\ t=\dfrac{0.160000478068}{0.02}\\\\\Rightarrow\ t=8.0000239034\approx8$

Hence, it will take 8 years.

How do you determine where an irrational number is located on a number line

zmey [24]

Answer:

Step-by-step explanation:

The square root of 2 is irrational, the square root of 3, 5, 6, 7, 8, 10, and any other positive number that is not a perfect square. You can find more by dividing an integer by an irrational number. (5 / sqr rt of 2...)

There are more irrational numbers than there are rational numbers. There are aleph-null rational numbers and aleph-one irrational numbers. (Aleph-null is the smallest size of infinity, aleph-one is the second size.)
