Step 1 : Rewrite the problem ...
(3^8 x 2^ -5 x 9^0)^ -2 x (2^-2/3^3)^4 x 3^28

Any non-zero expression raised to the power of equals

Step 2:(3^8 x 2^-5 x 1)^-2 x (2^-2/ 3^3)^4 x 3^28

Step 3: (3^8 x 2^-5 x1)^-2 x 2^-8/ 3^12 x 3^28

Any expression multiplied by remains the same

Step 4 : (3^8 x 2^-5)^-2 x 2^-8/3^12 x 3^28

To raise a product to a power, raise each factor to that power

Step 5 : 3^-16 x 2^10 x 2^-8/ 3^12 x 3^28

Reduce the expression with

Step 6: 3^-16 x 2^10 x 2^-8 x 3^16

Calculate the product

2^2

Evaluate , and then your answer is 4!!!!

The total cost of renting a popcorn machine for 6 hours is $48. What equation can be used to model the total cost y for renting
scoray [572]

Answer:

y=8x

Step-by-step explanation:

Let

y ----> the total cost for renting the popcorn machine

x ----> the time in hours

we know that

The total cost of renting a popcorn machine for 6 hours is $48

so

using proportion

Find out the total cost for renting the popcorn machine for x hours

\frac{48}{6}=\frac{y}{x}\\\\y=(48x)/6\\\\y=8x

Is a linear direct variation

The constant of proportionality or slope is equal to

k=8\frac{\$}{h}

That means ----> the total cost is $8 per hour

A pizza shop sells three sizes of pizza, and they track how often each size gets ordered along with how much they profit from ea
kari74 [83]

Answer:

μy = $6.56 ; σy = 2.77

Step-by-step explanation:

Given the data :

Mean μx= $8.56

Standard Deviation σx ≈ 2.77

Profit, Y on pizza with current promo :

Price off on pizza = $2

Y = x - 2

μx = E(x) = $8.56

μy = μ(x - 2)

μy = μx - $2

μy = $8.56 - $2

μy = $6.56

For the standard deviation of y

σx ≈ 2.77

σy = σ(x - 2)

σy = σx - 2

Constants are treated as 0 for standard deviation

σy = 2.77

A tissue can be 0.000075 meters thick.
Setler [38]

Answer:

The required expression is 7.5\times 10^5

Step-by-step explanation:

Consider the provided information.

A tissue can be 0.000075 meters thick and we need to represent it into scientific notation.

Steps to write a number in scientific notation.

  • Move the decimal place to the right so that the new number from 1 up to 10.
  • Determine the exponent, the exponent is the number of times you moved the decimal.

Now, consider the number 0.000075

Move the decimal point to 5 place right so that the new number from 1 up to 10.

Now, put the exponent the number of times you moved decimal. 7.5\times 10^5

Hence, the required expression is 7.5\times 10^5

Oliga [24]

A. 4y(2y + 5) = 4y(2y) + 4y(5) = 8y² + 20y

B. 7a(3a + 8b) = 7a(3a) + 7a(8b) = 21a² + 56ab

C. 13x³(3y + 2x²) = 13x³(3y) + 13x²(2x²) = 39x³y + 26x⁴ units²

D. 7m²(3m - 5) = 7m²(3m) - 7m²(5) = 21m³ - 35m² units²

Ok done. Thank to me :>
