Find all solutions to the equation (sinx-cosx)^2=1
svetoff [14.1K]

Answer:

x=\dfrac{\pi k}{2},\ k\in Z.

Step-by-step explanation:

Simplify the equation (\sin x-\cos x)^2=1:

\sin^2 x-2\sin x\cos x+\cos ^2x=1,\\ \\ (\sin^2x+\cos^2x)-2\sin x\cos x=1.\\

Since

\sin^2 x+\cos^2 x=1

and

2\sin x\cos x=\sin 2x,

we have

1-\sin 2x=1,\\ \\\sin 2x=0,\\ \\2x=\pi k,\ k\in Z,\\ \\x=\dfrac{\pi k}{2},\ k\in Z.

PLEASE MATH HELP ALGEBRA 1
S_A_V [24]
F(x) shows number of bees and g(x) shows number of flowers
f(x)=1500*(0.88)^n
g(x)=800-25n
n shows month
B)n=6
1500*(0.88)^6=696
800-25*6=800-150=650
c)it's hard to say because you should find n in this equation
1500*(0.88)^n=800-25n
but it seem n is between 6 and 7
