The equation to calculate percent error is # experimental - #theoretical / # theoretical * 100. The experimental value is 24 and the theoretical value is 42. Here's the calculation 24-42/42 * 100 = -42.86 rounded. Hope this helped :))
Thanks for the free points
Answer:
-3, -1, 1
Step-by-step explanation:
The values of x when f(x) = 0 are the points on the graph when the curve intercepts the x-axis.
From inspection of the graph, the curve intercepts the x-axis at
x = -3, x = -1 and x = 1
First, you should calculate the square footage of the fence.6ft∗300ft=1800ft2 Then to find the number of gallons of paint needed, divide the area of the fence by the area covered with each gallon of paint: 1800ft2÷400ft2=4.5 So, 4.5 gallons of paint, or rounding up, 5.
