Answer:
56.6m
Step-by-step explanation:
Using SOH = opp/hyp
Where θ = 45°
Hpy = 80m
Opp = ?
Sin θ = opp/hpy
Sin 45 = opp/ 80
Sin 45 × 80 = opp
0.7071 × 80 = opp
Opp = 56.568
~ 56.6m
Hence the height of the top of the tree is 56.6m
Answer:
x=3, y=-1
Step-by-step explanation:
To find if a function even or odd, subsitutue x with -x or evaluate f(-x)
if it is even,then f(-x)=f(x)
if it is odd then f(-x)=-f(x)
if neither then neither
f(-x)=-2(-x)^3+3(-x)^2
f(-x)=-2(-1)(x^3)+3x^2
f(-x)=2x^3+3x
it is neither fully negative nor the same
neither even nor odd
