<u>Let us assume that:</u>
We can also write it as:
Squaring both sides, we get:
By splitting the middle term:
<u>Therefore:</u>
<u>But x cannot be negative. </u>
Therefore, the value of the expression is 3.
Given:
We can also write it as:
This pattern will continue.
The answer is 452.16 cubic milimeters
The pitch depends on the value of frequency. The frequency can be calculated using this formula:
Frequency = wave speed / wavelength
where wave speed = 343.00 m/s
wavelength = 0.77955 m
Frequency = 343.00 m/s / 0.77955 m
= 434.00 s^-1
Therefore the pitch is low since the frequency is also low.
She ate 7 yards. This is because 3 feet=1 yard, so you can say that she ate 1 yard per day, for 7 days, so that makes it 7 yards.
