Answer:

I'm not 100% sure, but I think the answer is continuous because it contains all real numbers whereas a descrete function consists of only certain numbers in an interval.

Value discounting refers to the fact that the percieved value of the reinforcer is less the longer you have to wait for it. See

Answer:

there is an economic principle that states that 1 dollar today is worth more than 1 dollar in the future, since an invested dollar could earn interests and gain value.

For example, we can assume a 6% interest rate (0.5% monthly interest rate), and using the present value formula we can determine the present value of $100:

given to us in 30 days = $100 / (1 + 0.5%)¹ = $99.50
given to us in 150 days = $100 / (1 + 0.5%)⁵ = $97.54
given to us in 300 days = $100 / (1 + 0.5%)¹⁰ = $95.13

In order to calculate the value of $100 given to us tomorrow, we would need to determine a daily interest rate = 6% / 360 = 0.00017

$100 given to us tomorrow = $100 / (1 + 0.00017)¹ = $99.98

since the amount of money is not that large and the interest rate is rather low, the difference in value is not that large. But imagine if you used a 24% interest rate instead of 6% (monthly interest rate = 2%)

$100 given to us in 30 days = $100 / (1 + 2%)¹ = $98.04
$100 given to us in 150 days = $100 / (1 + 2%)⁵ = $90.57
$100 given to us in 300 days = $100 / (1 + 2%)¹⁰ = $82.03

as the interest rate increases, the present value decreases.

How many solutions does these equations have? One, infinite or no solutions?

s2008m [1.1K]

Answer:

1. 7(y + 3) = 5y+8: one solution

2. 10 + 6x= 2(5+3x): infinite solutions

3. 3x + 5 - x=2x + 7: no solutions

4. 4x - 4 = 2x + 8: one solution.

Explanation:

1. 7(y+3)=5y+8

a) Distributive property of multiplication over addtion:

7y + 21 = 5y + 8

b) Subtraction property of equalities:

7y - 5y = 8 - 21

c) Combine like terms:

2y = - 13

d) Division property of division:

y = - 13/2

e) Conclusion: the equation has one solution.

2. 10 + 6x = 2(5+3x)

a) Distributive property of multiplication over addition:

10 + 6x = 10 + 6x

b) Subtraction property of equality:

6x - 6x = 10 - 10

c) Simplify (combine like terms)

0 = 0

That is an identity, i.e. that is always true, no matter the value of x.

d) Conclusion: the equation has infinite solutions.

3. 3x + 5 - x = 2x + 7

a) Combine like terms:

2x + 5 = 2x + 7

b) Subtraction property of equalities:

2x - 2x = 7 - 5

c) Combine like terms (simplify)

0 = 2

That is always false, no matter the values of x.

d) Conclusion: the equation does not have any solutions.

4. 4x - 4 = 2x + 8

a) Subtraction property of equality

4x - 2x - 4 = 2x - 2x + 8

b) Combine like terms

2x - 4 = 8

c) Addtiion property of equalities:

2x = 8 + 4

d) Combine like terms (simplify)

2x = 12

e) Division property of equalities:

x = 6

f) Conclusion: the equation has one solution
