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
Answer:
-2,4
Step-by-step explanation:
i think
X = {0, 2, 4, 6, 8}.
=> f(x) = 2x - 1
x f(x) = 2x - 1
0 2*0 - 1 = - 1
2 2*2 - 1 = 3
4 2*4 - 1 = 7
6 2*6 - 1 = 11
8 2*8 - 1 = 15
Answer: {-1, 3, 7, 11, 15}
