Which sets of vectors are orthogonal? Check all that apply. a = 〈–1, 0〉 and b = 〈1, 0〉
c = 〈1, 0〉 and d = 〈0, –1〉
e = 〈–4, –6〉 and f = 〈12, 8〉
g = 〈4, –6〉 and h = 〈12, 8〉
v = 〈10, –5〉 and w = 〈–10, –20〉
x = 〈10, –5〉 and y = 〈–10, –2〉

Arecipe uses 2 cups of sugar to make 32 brownies. how many cups of sugar are needed to make 72 brownies?

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
