Sorry for my bad hand writing lol
Answer:
F(2) = 6
Step-by-step explanation:
Given that F(x) =x^2+2, evaluate F(2).
The above equation is a function of x
Such that for every value of x at a given time, the equation results to equation takes a different value at that time. For every value of x, the value is simply substituted into the equation to find the solution of the equation at that point. The above equation is a quadratic function since the highest power of x is 2.
F(x) =x^2+2,
To evaluate F(2),
Substitute x = 2 in equation x^2+2
It becomes
2^2 + 2 = 4 + 2 = 6
So F(2) = 6
Answer:
1303.45 cm
Step-by-step explanation:
The triangles formed by a rod and its shadow and a tree and its shadow are similar triangles, so the ratios of their heights to the lengths of their shadows are equal.
Let x be the height of the tree. Setting the ratios equal, we get:
180/116 = x/840
Solve for x:
x = 840 * (180/116)
x ≈ 1303.45 cm
Degree is 1 term is monomial
