Answer: 8.4

Step-by-step explanation:

$Tan=\frac{opposite}{adjacent}$

$o=Tan*a\\o=tan(45)*4.2\\o=6.8$

Now use the pythagoream's theorem.

$c^2=a^2+b^2\\c=\sqrt[]{a^2+b^2}\\c=\sqrt[]{(6.8)^2+(4.2)^2}\\ c=\sqrt[]{46.24+17.64}\\c=\sqrt[]{63.88}\\ c=7.99\\c=8$

What is the range of this relation?

VARVARA [1.3K]

Answer:

Domain = {-5,2,4,6,8,9), range = (-3,-1,0,4,6,7}

Step-by-step explanation:

{(2,4), (8,-3), (-5,-1), (4,6), (6,7), (9,0)}

The domain is the input and the range is the output

domain is { 2,8,-5,4,6,9} and the range is {4,-3,-1,6,7,0}

We put the numbers in order from smallest to largest

Domain = {-5,2,4,6,8,9), range = (-3,-1,0,4,6,7}

Answer: 2.)non function 3.)non function 4.) function 5.)non function 6.) non function 7.)function 8.)non function PART B 1.)non function 2.)function 3.) function

Step-by-step explanation: a function is when the domain (x) all each have one answer like (-2.6)(7,4)(8,6) there can be repeating ranges (y) just not domains.

A non function is when one domain (x) has multiple ranges(y) like (7,2)(-9,6)(7,9) the 7 repeats twice giving it two ranges, which causes it to be non functional. hope that helped :))
