Answer: (gºh)(25)=2

Step-by-step explanation:

1. This exercise is about Composition of functions, then you have:

2. Then, you have that

(gºh)(25) $=g(h(x))=\sqrt{x}-3$

3. Now, you must substitute 25 into the function, as you can see below:

(gºh)(25) $=\sqrt{25}-3$

4. Simplify the fucntion.

5. Therfore, you obtain:

Answer:

60.2 m

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you ...

Tan = Opposite/Adjacent

The width of the river is the side of a right triangle opposite the angle of 76°. The 15 m distance is the length of the side adjacent to the measured angle. So, we have ...

tan(76°) = width/(15 m)

Multiplying by 15 m, we get ...

width = (15 m)tan(76°) ≈ 60.2 m

The width of the river is about 60.2 m.
