If 5^3b-1=5^b-3 what is the value of b

Mathematics

Neporo4naja [7]3 years ago

Answer:

b=-1

Step-by-step explanation:

5^{3b-1} = 5^{b-3}

For any exponent, a^x

'a' is the base and x is the exponent

when the base are same on the both sides of equation then we equate the exponent

3b-1=b-3

we solve for b

Subtract 'b' on both sides

2b -1= -3

Add 1 on both sides

2b = -2

Divide by 2 on both sides

b=-1

Gnom [1K]

Answer:

The rule of 72 is used to determine how long it will take an investment to Double

For an Investment of $5,000 earning 7% annually, this will take about ten years

Step-by-step explanation:

The rule of 72 says that to find the number of years required to double your money at a given interest rate, you just divide 72 by the interest rate

Example:

If you want to know how long it will take to double your money at 9% interest, divide 72 by 9 you will get 8 years

The formula of the rule of 72 is Y = \frac{72}{r}

Let us complete the missing

The rule of 72 is used to determine how long it will take an investment to Double

The missing word is "Double"

∵ The investment is $5,000

∵ The annual interest is 7%

- By using the rule of 72

∵ Y = \frac{72}{r}

∵ r = 7

∴ Y = \frac{72}{7}

∴ Y = 10.29

- Round it to the nearest year

∴ Y ≅ 10 years

For an Investment of $5,000 earning 7% annually, this will take about ten years

The missing word is "ten"
