Answer:
2
Step-by-step explanation:
The curve's highest value is -1.
The curve's lowest value is -5.
For a symmetrical wave like this*, the amplitude is half the difference between the highest and lowest values:
1/2(-1 -(-5)) = 2
The amplitude is 2.
_____
* There is no general agreement as to how to compute the amplitude when the wave is asymmetrical. Some authors use the same formula. Some consider the amplitude to be the maximum deviation from average. Some define only a "peak-to-peak" amplitude in those cases. The meaning of "amplitude" in those cases depends on the context in which the question is asked.
2 * 864 = 1728 (lol) and then 1728 / 3 = 576 square feet
Answer:
Step-by-step explanation:
y = mx + b
Here, slope = m
y = 2x - 3
m = 2
Y would be the output value after inputting an X value and solving the necessary equation.
On the pictured graph, the numbers along the bottom are the X values and the numbers along the side are the Y values.
Looking at where the yellow dots are located on the X axis, there ia a dot at 0, 7, 14, 21, 28 and 35.
Now look at the corresponding Y values for each of those dots, they are at 0, 42, 84, 126, 168 and 210.
To find the proportionality of the graph using the equation y =kx, we can fill in the Y and X values and solve for k.
using x = 7 and Y = 42, the equation becomes 42 =k(7).
To solve for k divide both sides by 7: k = 42/7 = 6
When you replace the x and Y with the other numbers on the graph k is also equal to 6, so the correct equation would be B. y = 6x
