(64/9)^(-2/3) Simplify the expression

Answers

Answer 1

Answer: cubert64^2 = cubert 4096 then this equals 16
cubert9^2 = cubert81 then this equals 3 cubert3
therefore, ( 16 / 3cubert3)^ -1 so this would shift it to be 3cubert3 / 16

During a period of deflation, the graph of the consumer price index (CPI) will rise. True ? Or False ?

Answers

During a period of deflation, the graph of the consumer price index (CPI) will rise. False

Why is Deflation a problem?

Economists fear deflation due to the fact falling expenses causes a decrease in customer spending, which is a prime thing of economic growth. companies reply to falling charges by slowing down their production, which results in layoffs and revenue reductions. This similarly lowers call for and costs.

What happens when there is Deflation?

Deflation is when purchaser and asset charge lower over time, and purchasing strength will increase. essentially, you may purchase greater items or services the day after today with the equal amount of cash you have today. that is the mirror photograph of inflation, that's the sluggish boom in charges across the economic system.

What are the zeros of the polynomial function: f(x) = x3 + x2 – 6x ? ...?

Answers

The solution to the problem is as follows:

　
x³ + x² − 6x = 0
x (x² + x − 6) = 0
x (x − 2) (x + 3) = 0
x = 0, 2, −3

f(x) = 2x³ + 5x² + 6x − 4
f(−x) = −2x³ + 5x² − 6x − 4

Let's look at signs only and how many sign changes there are:
f(x) = + + + −
1 sign change ----> 1 positive root
f(−x) = − + − −
2 sign changes ----> 2 or 0 negative roots

Min. number of real roots = 1 ----> max. number of complex roots = 2
Max. number of real roots = 3 ----> min. number of complex roots = 0

Ava's dog weighs 56 kilograms. Marty's dog weighs 7/8 as much. How much does Marty's dog weigh?

Answers

Answer:

49 kg.

Step-by-step explanation:

We have been given that Ava's dog weighs 56 kilograms. Marty's dog weighs 7/8 as much. We are asked to find the weight of Marty's dog.

To find the weight of Marty's dog, we will multiply 56 by $(7)/(8)$ .

$\text{Weight of Marty's dog}=56\text{ kg}* (7)/(8)$

$\text{Weight of Marty's dog}=7\text{ kg}* 7$

$\text{Weight of Marty's dog}=49\text{ kg}$

Therefore, the weight of Marty's dog is 49 kilograms.

49 kilograms!
56:8=7 (is the 1\8)
so the 7\8 are 7*7=49 kilograms

At the metal-casting company where you work, you must set up a conveyor system to move castings from the furnace to the heat treatment area 55 yards away.
