Answer:
Step-by-step explanation:
hi there.
-11/18 please check photo for work.
given,
f(x)=x^2 +2
now
f(-x)=(-x)^2 +2 = x^2 +2= f(x)
since f(-x)=f(x)
the given function is even
Answer:
x = 200.674
Step-by-step explanation:
tan∅ = opposite/adjacent
Step 1: Find length of <em>z</em>
tan70° = 119/z
ztan70° = 119
z = 119/tan70°
z = 43.3125
Step 2: Find length <em>z</em> + <em>x </em>(denoted as <em>y</em>)
tan26° = 119/y
ytan26° = 119
y = 119/tan26°
y = 243.986
Step 3: Find <em>x</em>
y - z = x
243.986 - 43.3125 = x
x = 200.674
