Someone help I don't know this trig question

solong [7]

Answer:

Bill is 9.80 km apart from Concert

Step-by-step explanation:

It's given in the question,

m∠B = 75°

m∠C = 45°

By triangle sum theorem,

m∠A + m∠B + m∠C = 180°

m∠A + 75° + 45° = 180°

m∠A = 180° - 120°

m∠A = 60°

By sine rule,

$\frac{\text{sin}(\angle A)}{BC}=\frac{\text{sin}(\angle C)}{AB}$

$\frac{\text{sin}(60)}{BC}=\frac{\text{sin}(45)}{8}$

BC = $\frac{8\text{sin}(60)}{\text{sin}(45)}$

= 9.80 km

Therefore, Bill is 9.80 km apart from Concert.

A ball is thrown upward from the top of a building. The function below shows the height of the ball in relation to sea level, f(

ratelena [41]

Answer:

The average rate of change of f(t) from t = 3 seconds to t = 5 seconds is -80 feet per second.

Step-by-step explanation:

The function that models the height of the ball is:

$f(t)=-16t^2+48t=160$

At t=3, $f(3)=-16(3)^2+48(3)+160=160$

At t=5, $f(5)=-16(5)^2+48(5)+160=0$

The average rate of change is simply the slope of the secant line connecting.

$(3,f(3))$ and $(5,f(5))$ .

The average rate of change

$=\frac{f(3)-f(5)}{3-5}$

$=\frac{160-0}{-2}$

$=-80fts^{-1}$
