Which relations are functions? Select function or not a function for each graph

1 answer:

7 0

This is NOT a function. The reason why is because we are able to pass a single vertical line through more than one point on the cure. It fails the vertical line test.

For it to be a function, every input x must lead to exactly one output y

Two angles are complementary. one of the angles is twice the other.the larger angle has a measure of

horrorfan [7]

Complimentary angles will add up to 90 degrees

x + y = 90
x = 2y

2y + y = 90
3y = 90
y = 90/3
y = 30......this is one angle

x = 2y
x = 2(30)
x = 60.....this is ur other angle

and ur larger angle is 60 degrees

fie abc un triunghi cu masura unghiului a de 90 de grade ab este 6 cm bc=10 si ca=8 calculati;sin b; tg b; sin c; tg c; cos b; c

lions [1.4K]

SinB = cosC = AC / BC = 8/10 = 4/5;
tgB = ctg C = AC/AB = 8/6 = 4/3, because we use T. Pitagora for calculating AB;
sinC = cosB = AB/ BC = 6/10 = 3/5;
tgC = ctgB = AB/ AC = 6/8 = 3/4.
