X + y = -10
-3x -y = 2
We'll try with x as a small number and y with a big number to try and balance it out.
-3 - 7 = 10
9 - 7 = 2
X = -3
Y = -7
Hope this helps! :)

balandron [24]

Answer:

=  \frac{\sin(2 \alpha )  +  \cos(2 \alpha )  -  \cos(6 \alpha ) }{ \sin(4 \alpha )  + 2 { \sin }^{2}  \alpha  - 1}  \\  =  \frac{ \sin( - 270) +  \cos( - 270)  -  \cos( - 810)  }{ \sin( - 540)  + 2 { \sin }^{2}( - 135) - 1 }  \\  =  \frac{1}{ - 2}  \\  =  - 0.5

The water level in a tank can be modeled by the function h(t)=8cos(pi t /7)+11.5, where t is the number of
denis23 [38]

Answer:

NO amount of hour passed between two consecutive times when the water in the tank is at its maximum height

Step-by-step explanation:

Given the water tank level modelled by the function h(t)=8cos(pi t /7)+11.5. At maximum height, the velocity of the water tank is zero

Velocity is the change in distance with respect to time.

V = {d(h(t)}/dt = -8π/7sin(πt/7)

At maximum height, -8π/7sin(πt/7) = 0

-Sin(πt/7) = 0

sin(πt/7) = 0

Taking the arcsin of both sides

arcsin(sin(πt/7)) = arcsin0

πt/7 = 0

t = 0

This shows that NO hour passed between two consecutive times when the water in the tank is at its maximum height
