Answer:

x = 5.6

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2+b^2 = c^2

4.8 ^2 + x^2 = 7.4^2

23.04 +x^2 =54.76

Subtract 23.04 from each side

x^2 = 54.76 - 23.04

x^2 =31.72

Take the square root of each side

x =5.632051136

Rounding to the nearest tenth

x = 5.6

Answer:

Both are correct

Step-by-step explanation:

A store is having a 20% off sale. Micheal says that he can find the sale price of an item that has a regular price of "p" by evaluating the expression 0.8"p". Susan says that she can find the sale price for the same item by evaluating the expression "p"-0.2"p"

Store is having 20% off sale. Discount is 20%

LEt the regular price is 'p'

The discount price is 20% of p that is 0.2p

Sale price is original price - discount price

that is p - 0.2p . So Suna is correct

p - 0.2 p = 1p- 0.2p = 0.8p

So Michel is also correct

Hence, Both are correct

Answer:

z^ {8/5}

Step-by-step explanation:

$(z^{\frac{-4}{3})^{\frac{-6}{5} } \\We\ know\ that\ a^{(b)^c} = a^{bc}\\\\Hence, \\\\{z^{\frac{-4}{3})^{\frac{-6}{5}}\\}={z^{\frac{-4}{3}*\frac{-6}{5}\\}\\=z^{\frac{24}{15}}\\=z^\frac{8}{5}$
