Answer:
0
Step-by-step explanation:
f(x) = -3x^2 + 6x
Let x=2
f(2) = -3*(2)^2 + 6(2)
=-3(4) +12
= -12+12
=0
Answer:
50√3 ≈ 86.6 m
Step-by-step explanation:
The geometry can be modeled by a right triangle with the height of the kite being the leg opposite the 60° angle. The hypotenuse has the given length of 100 m.
The mnemonic SOH CAH TOA reminds you that the relation between angles and the sides of interest here is ...
Sin = Opposite/Hypotenuse
sin(60°) = (kite height)/(100 m)
kite height = (100 m)·sin(60°) = (100 m)(√3)/2
kite height = 50√3 m ≈ 86.6 m
<h3>Given :</h3>
<h3>To Find :</h3>
<h3>Solution :</h3>
From point A,



Now, we are given ∠A = 45°


Now, we know that tan45° = 1



Now, by Pythagoras' theorem,
AC² = BC² + AB²






Answer:
The area is 8
Step-by-step explanation:
If the perimeter is 12, we can just start guessing and checking. in this case, if 4 is the length, that means 2 is its width, since 4-2=2. then you find the area(basexhight) 4x2=8!
