Answer:
4Hz
Step-by-step explanation:
Standard form of a sine or cosine function,
y = acos(b(x+c))
where a is the amplitude, b is the value to find the period. and c is the phase shift.
Period = \frac{2\pi}{b}
From the equation given in the question,

We can see:
Amplitude = 3,
Period = \frac{2\pi}{8\pi} = 1 / 4
Phase Shift = 1 / 16
Now we want to find the frequency.
Frequency = 1 / Period
= 1 / (1/4)
= 4Hz
Yes because if you look at the tenths place you will see that 8 is bigger than 7
Answer:
What to chat
Step-by-step explanation:
y r u working so late
We will check if y and 60cm are parallel.
If the lengths 28cm, 56cm and 15cm, 30cm are in proportion, then y and the segment 60cm are parallel.

OK. We know: y and 60cm are parallel. Therefore we have equation:

<h3>Answer: y = 90 cm.</h3>
Answer:
it already is less than $675
Step-by-step explanation:
if u multiply 20% by 3 then put it into decimal form, you get .60 which then u can then multiply that by $2500 and get $417
( might be wrong :'(
