Answer:
936m
Step-by-step explanation:
What we have here is a rght triangle, where one leg is the hight between the nest and the bird (400 - 20 =380) and the other is the distance between the bird and the nest linearly from the ground (name it X). The hypotenuse is the distance the bird will fly ( name it H).
Is not clear if we need to find X or H so we will find both.
First, to find H we use the trigonometric formula:
Sin(24) = leg opposed / hypotenuse
Sin(24) is 0.406 aprox
So,
0.406 = 380/h -> h = 380/0.406 = 936 (aprox)
Then we find X, the adjacent leg to 24° using the formula:
Cos(24) = X / hypotenuse
Cos(24) is approximately 0.91
So:
0.91 = X / 936 -> X=0.91*936= 852 (aprox)
So, the distance ir 936 ir 852, depending on what you need. The statement is not very clear (however I guess it is 936 as is the distance the bird Weill fly)
the coefficient is the number before x
in this case the coefficient is -1.

i am doing online school
Step-by-step explanation:
We have that
<span>y=(1/2)x+1
we know that
the point p h</span><span>as a y-coordinate of 5
therefore
</span><span>I substitute the value of y = 5 in the equation of the line
5=</span>(1/2)x+1--------> 5-1=(1/2)x------> 4=(1/2)x-----> 8=x
x=8
the answer is
the x coordinate of p is x=8
Hello! So the equation you have to solve is 49 + j = 81. You want to figure out j, so you have to isolate the variable. This means, you should subtract 49. In math, if you do something to one side of the equation, you have to do it to the other. So, you must subtract 49 from 81. This means j= 32.
I hope this helps! If you need help with how to do the subtraction equation 81-49, please let me know!
