The relationship is a function. A function is an equation of graph that has no repeated x values. In this graph, each x value has a different y value, whether it's (1, 70) or (9,95)
If Rachel gets anything other than a 95, the x value of 2 will have more than one y value: 95 and whatever grade Rachel gets. Therefore it will no longer be a function.
Answer:
4k-6
Step-by-step explanation:
I know the equation is 1/cos
but is it negative sqrt(3)/2 or positive?
or is it negative 1/2 or positive?
This makes the reference angle π/6 or 30º which gives cos 30º=√3/2 or a sec value of 2/√3=2√3/3
sec(-5pi/6)=-2√3/3
Ted is incorrect because 3/10 is the same as .30 which is then multiplied by 100 and given the product of 30.
.3×100=30
