Write the equation of a sine function that has the following characteristics.
2 answers:
GIVEN :
Amplitude:– 7
Period:– 9π
Phase shift:– 1/4
ANSWER :
As we know that,
y = A sin{B(x + C)} + D , where A is amplitude; B is the period; C is the phase shift & D is the vertical shift.
Since, we know period is 2pi/B, Phase shift is -C & vertical shift is D.
So, y = 7sin{2π/9(x - 1/4)} + 0
y = 7sin{π(2/9x - 1/18 } .
Answer:
Step-by-step explanation:
we are given
Amplitude:7 Period:9π Phrase shift:¼ remember that,
where A is the Amplitude
B is the Period
C is the Phase shift
D is the vertical shift
note that, since D isn't given we'll take it 0
altogether substitute:
hence,
our equation is
and we are done!

Answer:
125.72
Step-by-step explanation:
radius equals pi(r)2
rectangle equals b times h
radius is 6.28
rectangle is 132
you now subtract them
132 minus 6.28 which is 125.72

Answer:
x=-1, y=2
Step-by-step explanation:
2(2x+4)=6x+10
2x=-2
x=-1
y=2(-1)+4
y=2
A sample would be easier then having to survey the entire population due to the amount of people in a population.
He has biked 2.85 miles. By multiplying 28.5 and 0.10 or dividing 28.5 by 10 you get the total 2.85. To check your answer you can multiply 2.85 by 10 which equals 28.5. Hope this helps!
