Answer:

26

Step-by-step explanation:

Data provided in the question:

set {1, 2, 3, 5, 11}

Now,

Total number of different choices of a number available = 5

Therefore,

Number of ways to choose 2 distinct numbers=  ⁵C₂

Number of ways to choose 3 distinct numbers=  ⁵C₃

Number of ways to choose 4 distinct numbers=  ⁵C₄

Number of ways to choose 5 distinct numbers=  ⁵C₅

therefore,

Total number we can get

= ⁵C₂ + ⁵C₃ + ⁵C₄ + ⁵C₅

= \frac{5!}{2!(5-2)!}+\frac{5!}{3!(5-3)!}+\frac{5!}{4!(5-4)!}+\frac{5!}{5!(5-5)!}

=  \frac{5\times4\times3!}{2!3!}+\frac{5\times4\times3!}{3!\times2!}+\frac{5\times4!}{4!\times1!}+\frac{5!}{5!\times0!}

= 10 + 10 + 5 + 1

= 26

Which table represents a direct variation function?
Luda [366]
Direct variation is y=kx where k is a constant

the fiest way to see if it is direct or not, is if x increases, then y increases as well,
then we see if y=kx is valid, basically if we have a constant of variation


the first one x increase and y increase
see if same constant
y=kx
-4.5=-3k
1.5=k
so

see next one
-1 and 3
-3=-1(k)
-3=-1(1.5)
-3=-1.5
false
not it




2nd is increase and y decrease, so not direct variation

3rd is x is same but y increase so nope

4th is x increase and y increase, now test the constant
-7.5=-3k
2.5=k

-1 and -2.5
-2.5=-1k
-2.5=-1(2.5)
-2.5=-2.5
true

1035.33156649 meters high is the helicopter flying over the building.

Given that, an observer (O) is located 900 feet from a building (B). The observer notices a helicopter (H) flying at a 49° angle of elevation.

We need to find how high is the helicopter flying over the building.

<h3>How to find the height of the building using trigonometry?</h3>

To measure the heights and distances of different objects, we use trigonometric ratios.

Here, use the Tangent rule to calculate the height of the building.

tan(angle) = opposite/adjacent

Now, tan 49°=h/900

⇒h=1035.33156649 meters

Therefore, 1035.33156649 meters high is the helicopter flying over the building.
