Answer:

Point on Midline (0,3)

Maximum (9π/2,3)

Minimum (-9π/2,-3)

Step-by-step explanation:

in the given sine function which is in the form of f(x) = a sin(bx+c) +d

a = amplitude

period = frequency = 18π

Therefore b = 2π/18π = 1/9

Y intercept = vertical shift = 3

Horizontal shift = d = 0

Therefore the sine function will be

f(x) = 6 sin(x/9) + 3

Now first point on the midline is (0,3)

Second point is maximum (9π/2,9)

Third point be a minimum value ( -9π/2,-3)

The product of two numbers is 20. If one of the numbers is 4/7 what is the other number?
TiliK225 [7]

Answer:

35

Step-by-step explanation:

1. Translate the question into an equation:

  • \frac{4}{7}x = 20

2. Multiply both sides by 7/4.

  • \frac{4}{7}x * \frac{7}{4} = 20 * \frac{7}{4}
  • x = \frac{140}{4}
  • x = 35

which ordered pairs are a solution to the question y=8× select all that apply (-1,-7)(2,16)(1,8)(-2,-6)​
abruzzese [7]

Answer:

(2,16) , (1, 8)

Step-by-step explanation:

(-1,-7), x = -1 and y = -7

plug in

y = 8x

-7 = 8 * -1

-7 = -8, false

(2,16), x=2 and y = 16

plug in

y= 8x

16 = 8 * 2

16 = 16, so it is a solution

(1,8), x = 1 and y = 8

plug in

y = 8x

8 = 8 * 1

8 =8 , so it is a solution

(-2,-6), x = -2, y = -6

plug in

y = 8x

-6 = -2 * 8

-6 = -16, false

Which of these properties is preserved exclusively under dilation?
masya89 [10]
The property that is preserved under dilation is the similarity. The answer is letter A. Dilation of a figure starts from the very center of it and then continually increased or decreased depending on the desired size. It is similarity that is under dilation because no matter how big or small the size of the figure is, it has a similar feature from the original one.
