20,000 Hz = 2 × 10^4 Hz
150,000 Hz = 1.5 × 10^5 Hz
Answer:
The time it took for the bottle rocket to reach a height of 200 feet is 60 seconds.
Step-by-step explanation:
The function for the height of the bottle rocket (in feet), <em>t</em> seconds after it is launched is:

Compute the value of <em>t</em> as follows:




Thus, the time it took for the bottle rocket to reach a height of 200 feet is 60 seconds.
The vertex’s coordinates are (-1,4)
Answer:
length of the photograph will be 4.2 in. after pressing the button 5 times.
Step-by-step explanation:
By pressing the button, every time size of the photograph gets reduced by 12%.
Therefore, the sequence formed by the reduced sizes of the photo will be a geometric sequence and the formula for the size of the reduced image will be,
L = 
Where l = Actual length of the photograph
L = length of the reduced image
n = Number of times the button has been pressed
For l = 8 in. and n = 5
L = 
= 
= 4.22 in
L ≈ 4.2 in.
Therefore, length of the photograph will be 4.2 in. after pressing the button 5 times.
<u><em>Answer:</em></u>
37/96
<u><em>Explanation</em></u>:
Hazel uses 1yd for 60 charms, so for 5/8yd she would use 5/8×60=37.5.
Because she can’t use a fraction of a charm, she would use 37 charms which is 37/96 of the charms she has.
