use cross products

(3r+6) *2 = 9*(2r-4)

6r+12 = 18r-36  distribute

12    = 12 r -36    subtract 6r from each side

48 = 12r  add 36 to each side

4=r  divide by 12

State 7m to 250cm as a ratio in its lowest terms
madam [21]
First you have to convert the numbers to the same units.  Either m to cm or cm to m.
To go from meters to centimeters you multiply the number by 100.
7*100=700cm
Now you have 700cm/250cm.  This needs simplified
I divided each number by 50 to get 14 and 5
14cm/5cm or 14cm:5cm

The height of the tide over time is shown on the graph. Which of the following equations can be used to reasonably model the dat
Murljashka [212]

Answer:

Option 1.f(x) = -3sin(\frac{\pi }{6}x)+3

Step-by-step explanation:

The height of the tide over the time is shown on the graph.

Its a periodic function (sine graph) plotted on a graph in which variables are

Amplitude a = (6-0)/2 = 3

Period = 15-3 = 12

Therefore b = 2π/period = 2π/12 = π/6

horizontal shift = 0

Vertical shift = 3

Since the function starts with negative sign that means its below the x-axis.

So as per standard formula of f(x) = asin(bx+c)+d

option which matches all these parameters is Option 1. f(x) = -3sin(\frac{\pi }{6}x)+3
