Kaj is flying a kite, holding her hands a distance of 3.5 feet above the ground and letting all the kite’s string play out. She
Savatey [412]

Using trigonometric ratio, the height of the ground above the ground to the nearest hundredth is 44.85 ft

The situation forms a right angle triangle.

<h3>What is a right angle triangle?</h3>

Right angle triangle has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios.

Therefore, the length of the string is the hypotenuse side of the triangle formed . The opposite side of the triangle is the height of the kite form the ground.

Therefore, the height of the kite form the ground can be found as follows;

sin 33° = opposite / hypotenuse

sin 33° = h / 75

cross multiply

h = 75 × sin 33

h = 40.8479276261

h = 40.84

The height of kite from ground = 40.847 + 3.5  = 44.3479276261 = 44.85 ft

BigorU [14]

Answer:3125/6561


Step-by-step explanation: Because there are four digits and the question is asking the odds of have odd numbers, the chances of an odd number between 0-9 is 5. 5 out of 9.

(5/9)^4 gives you 3125/6561 or 48%

Will mark brainiest for simplest and most coherent answer. What does it mean if an x (input) or y (output) value doesn't make se
Maksim231197 [3]

Answer:

I tried to answer but I still would like to know what doesn't make sense.

Considering the identity:

\sec^2\theta-\tan^2\theta=1 \implies |\sec\theta|\geq1

$\forall\;\theta\in\mathbb{R}-\{(2n+1)\frac{\pi}{2}, n\in\mathbb{Z} \}$

The identity is true whenever both sides are defined. It is not supposed to hold the values when we have division by zero, because it is undefined.

If the value doesn't make sense, it is probably not a function, or it is undefined by the given value of x.

Let's go back to the definition of function again:

A function relates a set of inputs and a set of allowable outputs where each input is related to only one output. It basically defines the relation of ordered pairs.

Hope it helped you a bit.
