Answer:

The graph in the attached figure

Step-by-step explanation:

we know that

In a reflection across the y-axis the y-coordinate remains the same, but the x-coordinate is transformed into its opposite

we have

f(x)=2(0.4)^{x}

The reflection of f(x) across the y-axis is equal to the function g(x)

g(x)=2(0.4)^{-x}

The graph in the attached figure

Two equations are given below: m + 4n = 8 m = n - 2 What is the Solution ?
Sophie [7]
M+4n=8
m=n-2
we see that m=n-2
so we can subsitute 'n-2' for m in the first equation
(n-2)+4n=8
n-2+4n=8
5n-2=8
add 2 to both sides
5n=10
divide by 5
n=2
subsitute
n=2
m=n-2
m=2-2
m=0

m=0
n=2

the answer is c. 0,2

PROVE :<br><br>sin^2(-300°).cos^2 (120)+ cos^2(-240 ).sin^2(390)=1/4​
leva [86]

Step-by-step explanation:

\sin {}^{2} ( - 300)  \cos {}^{2} (120)  +  \cos {}^{2} ( - 240)  \sin {}^{2} (390)  =  \frac{1}{4}

\sin {}^{2} (60)  \cos {}^{2} ( {}^{} 120)  +  \cos {}^{2} (120)  \sin {}^{2} (30)

\frac{3}{4}  \frac{1}{4}  +  \frac{1}{4}  \frac{1}{4}

\frac{3}{16}  +  \frac{1}{16}  =  \frac{4}{16}  =  \frac{1}{4}
