<h2>Step-by-step explanation:</h2>

Hlug\ in\ the\ value\ of \left.\ t.\right\}

The\ infital\ ampunt\ in\ the\ sample:

t=0_{-1}\ \ \ \ \ f(t)=39\omega\bullet(\frac{1}{2})^\frac{0}{14}

                        =3900\ g.

Ater\ bo\ busis.

t=6,\ \ \ \ \ A(t)=2900\times(\frac{1}{2})^\frac{60}{14}

                       =3900\times(\frac{1}{2})^\frac{30}{7}

Answer:

x = 88.2

Step-by-step explanation:

The angle at the top of the triangle = 90° - 10° = 80°

and the left side of the triangle is x ( opposite sides of a rectangle )

Using the tangent ratio in the right triangle

tan80° = \frac{opposite}{adjacent} = \frac{500}{x}

Multiply both sides by x

x × tan80° = 500 ( divide both sides by tan80° )

x = \frac{500}{tan80} ≈ 88.2
