If xy=0, assume that x and/or y=0
so we already gots factored
therfor
assume
3n-2=0 and 4n+1=0
solve
3n-2=0
3n=2
n=2/3
4n+1=0
4n=-1
n=-1/4
n=2/3 and/or -1/4
she went down the slope 10.2 meters, -10.2
then she jumped down to the lake 1.5 meters, -1.5
-10.2 - 1.5 = -11.7 meters.
so she pretty much went 11.7 meters down from her original location.
La formula para calcular cualquier descuento esta dada por (100 - descuento)/100
en ese caso seria Y = (1-0.3)X = 0.7X
<h3>
Answer: 30.78181 meters</h3>
The value is approximate. Round that however you need to.
========================================================
Explanation:
- lowercase a = side opposite angle uppercase A
- lowercase b = side opposite angle uppercase B
- b = AC
Using the law of sines, we can say:
a/sin(A) = b/sin(B)
45/sin(30) = b/sin(20)
b/sin(20) = 45/sin(30)
b = sin(20)*45/sin(30)
b = 30.78181 approximately
You'll need to make sure your calculator is in degree mode.
