Answer:

x = 6

Step-by-step explanation:

CT is a median, which means it divided AB into two equal parts so we can write the following equation:

7x + 9 = 5x + 21 transfer like terms to the same side of the equation

7x - 5x = 21 - 9 do the extraction

2x = 12 divide both sides by 2

x = 6

A train whistle is 580 Hz when stationary. It is coming toward you at 18.8 m/s. What frequency do you hear?

Usimov [2.4K]

Answer:

612 Hz.

Step-by-step explanation:

The frequency of the sound will be proportionally higher when coming towards you. The increase is related to the speed of the train.

So the frequency will be:

580 + (580 / 343) * 18.8

= 612 Hz.

This is called the Doppler effect.

Which of the following is equal to (3^-3)(3^7)? 3 ^-10 3 ^10 3 ^4 3 ^-4

bixtya [17]

Answer:

3⁴

Step-by-step explanation:

Hey there! To evaluate $\displaystyle \large{3^{-3} \cdot 3^7}$ , we can simply do by using one of exponent laws.

Laws of Exponent

$\displaystyle \large{a^m \cdot a^n = a^{m+n}}$

Hence, let m = -3 and n = 7. Therefore, $\displaystyle \large{3^{-3} \cdot 3^7 = 3^{-3+7} \to 3^4}$

Let me know if you have any questions regarding the exponent!
