2sin^2 2x=2<br><br> In the domain [0, 2pi)

djverab [1.8K]

Please type this as 2(sin 2x)^2=2 <span>2sin^2 2x=2 is confusing.

Reducing this expression: (sin 2x)^2 = 1

Taking the sqrt of both sides, sin 2x = plus or minus 1

If sin 2x = 1, then 2x must be pi/2 or 3pi/2, and so x must be pi/4 or 3pi/4.

Now you do this for sin 2x = -1.</span>

The equations y = 30x + 10 and y = –x2 + 150x + 10 model the daily sales of two car models, where x represents the number of day

yuradex [85]

Answer:

day 0, day 120

Step-by-step explanation:

You want to find the value of x that makes both y-values be the same:

y = y

30x +10 = -x^2 +150x +10

x^2-120x = 0 . . . . subtract the right side of the equation

x(x -120) = 0 . . . . . factor

Values of x that make this true are x=0 and x=120.

The same number of each car was sold on day 0 and day 120.
