59.4cm
Use Pythagorean theorem to find the diagonal (^ means exponent)
a^2 + b^2 = c^2
42^2 + 42^2= c^2
1764+1764=c^2
3528=c^2
square root both sides
c= 59.39696962
round and you get 59.4 cm
<span>My answer -
f(x)=x^3+2
To find the inverse function f(x)^-1 , we will assume"
y=x^3+2
y-2= x^3
==> x= (y-2)^1/3
==> f(x)-1= (x-2)^1/3</span>
P.S
Happy to help you have an AWESOME!!!!! day
You would have to find the proportionality of the two. If his shadow is 3 feet long, and the tree's shadow is 9 that means it is proportioned by 3. So the height of the tree would be 15.
2x+3x=
X is simply a letter
