Answer:
h - d = 477 meters
Where: h = original height
d = amount the helicopter descended
The original height of the helicopter is given to be h
Step-by-step explanation:
Using trigonometric ratio, the value of x is 63.6°
<h3>Trigonometric Ratio</h3>
This is the ratios of sides of a right-angled triangle with respect to any of its acute angles are known as the trigonometric ratios of that particular angle.
Trigonometric ratio are often coined as SOHCAHTOA
In the given triangle, we need to find the value of x using trigonomtric ratio.
Since we have the value of adjacent and hypothenuse, we definitely need to use cosine
cosθ = adjacent / hypothenuse
adjacent = 4
hypothenuse = 9
Substituting the values into the equation;
cos θ = 4 / 9
cos θ = 0.444
θ = cos⁻¹ 0.4444
θ = 63.6°

$17.80 in 1 hr
$1 in 1/17.80 hr
$675.00 in 675.00/17.80 hr
37.9 hours
Which is 38 hours after rounding it.
When the probability of an event is = 1 that means it's no longer a probability but a certainty, an assertion instead.
If today is Thursday, what is the probability tat tomorrow will be Friday?
It's equal to 1 since certainly tomorrow will be Friday
