A tourist looks out from the observation deck of the Space Needle in Seattle. The deck is at a height of 520 ft. She sees her fr

WARRIOR [948]

Answer:

Last option 527.7 ft

Step-by-step explanation:

From the diagram attached we can see the angle of depression is 80.2 which is equal to ∠ACB (alternate angles)

Height of the deck AB = 520 ft. and we have to calculate the distance H between the tourist and her friend.

Sin ∠ACB = $\frac{AB}{AC}$

Now we apply sin rule sin 80.2 = $\frac{520}{H}$

$.9854=\frac{520}{H}$

$H = \frac{520}{.9854} = 570 ft$

So the tourist and her friend are 527.7 ft apart.

What is the zero of the function below?

Ymorist [56]

x = 1

Step-by-step explanation:

Given data: $f(x)=3 \sqrt{x+3}-6$

Recall: If f(x) = 0, then x is called the zero of the function.

To find zero of the function, take f(x) = 0.

$\Rightarrow 3 \sqrt{x+3}-6=0$

Add 6 to both sides of the equation.

$\Rightarrow 3 \sqrt{x+3}=6$

Divide both sides of the equation by 3.

$\Rightarrow \sqrt{x+3}=2$

Taking square on both sides of the equation.

$\Rightarrow(x+3)=2^{2}$

⇒ x + 3 = 4

⇒ x = 1

Hence, the zero of the function is 1.
