What is period given by y=-2sin(2pi/7x)

1 answer:

7 0

Whenever the things contained by the sin function = a factor of 2pi , a complete cycle is made.
so in this case, whenever 2pi/7x = 2pi , a complete cycle is made.
2pi/7x = 2pi
1/7x = 2pi/2pi
1/7x = 1
7x = 1
x = 1/7
therefore, the period is x = 1/7 for every cycle

A landscaper is planting a row of 10 shrubs along the walkway shown below. There must be one shrub at the very beginning and one

rewona [7]

Answer:

$9d = 36$

Step-by-step explanation:

See attachment for complete question

$Length = 36ft$

$n = 10$

From the question, we understand that one shrub must be at both ends.

Taking the first as a point of reference, we're left with:

$(n - 1) * distance = 36$

Substitute 10 for n and d for distance

$(10 - 1) * d = 36$

$9 * d = 36$

$9d = 36$

Hence:

$9d = 36$ answers the question
