You can just use a calculator but it’s 65.23
This is an example of a
sine wave function. A given sine wave function has a standard form of:
y = A sin [B (x + C)] + D
Where,
A = absolute value of
amplitude
2 π / B = the period of
the sine wave
D = is the midline of y
C = phase of the sine
wave
Rewriting the given
equation into this form will yield:
f (x) = -7 sin[4 (x – π / 4)]
+ 2
Therefore from this form,
we can get the answers:
Amplitude = 7
Period = 2π / 4 = π / 2

Answer:
10,935 meters.
Step-by-step explanation:
Find how many meters she walks in 1 week, so you add the 1,720 and the 1,925 and you would get 3,645. If she does the same thing for 3 weeks, you multiply the 3,645 by 3, so you get 10,935 meters
Answer:
Yes
Step-by-step explanation:
The idea is to group up the terms into two groups, factor each group and then factor out the overall GCF
2x+16+xy+8y
(2x+16)+(xy+8y)
2(x+8)+(xy+8y)
2(x+8)+y(x+8)
(2+y)(x+8)
(x+8)(2+y)
Answer: Choice A
