Step-by-step explanation:
Answer:
Option A ![sin(A)=\frac{9}{15}](https://tex.z-dn.net/?f=sin%28A%29%3D%5Cfrac%7B9%7D%7B15%7D)
Step-by-step explanation:
we know that
![tan(A)=sin(A)/cos(A)](https://tex.z-dn.net/?f=tan%28A%29%3Dsin%28A%29%2Fcos%28A%29)
Solve for sin(A)
![sin(A)=tan(A)cos(A)](https://tex.z-dn.net/?f=sin%28A%29%3Dtan%28A%29cos%28A%29)
we have
![tan(A)=\frac{9}{12}](https://tex.z-dn.net/?f=tan%28A%29%3D%5Cfrac%7B9%7D%7B12%7D)
![cos(A)=\frac{12}{15}](https://tex.z-dn.net/?f=cos%28A%29%3D%5Cfrac%7B12%7D%7B15%7D)
substitute
![sin(A)=\frac{9}{12}(\frac{12}{15})](https://tex.z-dn.net/?f=sin%28A%29%3D%5Cfrac%7B9%7D%7B12%7D%28%5Cfrac%7B12%7D%7B15%7D%29)
![sin(A)=\frac{9}{15}](https://tex.z-dn.net/?f=sin%28A%29%3D%5Cfrac%7B9%7D%7B15%7D)
Answer:
(0,2)
Step-by-step explanation:
Answer:y=-10
Step-by-step explanation:
y=-1/2 4(6(2)+3)-2y
+2y 6(2) +2y
3y=-1/2 4(12+3)
multiplie 4 times 12 and 4 times 3
3y=-1/2 48+12
add 48 and 12
3y=-1/2 60
divide -1/2 and 60
3y/3=-30/3
y=-10
The water has no larvae at -10 degrees Celsius and 20 degrees Celsius
