Answer:
The first month new members have to pay 188 dollars for the membership.
The equation is 160x+28=y
x stands for the number of months and y stands for the total cost.
For the first month (membership starts) the total cost is 188$. For the second month the total money paid would be 348$. For the third month the total money paid would be 508$. And so on you can use the equation to solve for more months. Just substitute x for the number of months you are solving for.
This can be solved in several ways. First with the basic trigonometry identity of tangent and sine (or cosine)
tanα=opposite side/adjacent side...
tanα=20/3
α=arctan(20/3)
Then sinα=h/x
x=h/sinα where α found above and h=20m:
x=20/sin(arctan(20/3)) meters
x≈20.22m (to nearest one-hundredth of a meter)
...
We could also use the Pythagorean Theorem which is easier for this problem...
x^2=h^2+d^2
x^2=20^2+3^2
x^2=400+9
x=√409 meters
x≈20.22 meters...
...
We could also use the Law of Cosines:
x^2=a^2+b^2-2abcos90 (-2abcos90=0 so we essentially get what we just did above)
x^2=a^2+b^2
x^2=409
x=√409
x≈20.22 meters

Answer:
<em>B. Lands on red 120 times </em>
<em>D. Lands on yellow 44 times</em>
Step-by-step explanation:
<em>Mark me brainliest if i'm right </em>
Always multiply y by 2. And then add on any number you want as long as it’s positive
