Answer:
Exact form : r=2squareroot2, -2squareroot2
Decimal form : r=2.8284212...,-2.82842712....
Step-by-step explanation: Take the root of both sides and then solve.
Hope this helps you out.
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>

Answer:
4D - 1
Step-by-step explanation:
So, if Ted saves $D for 4 weeks, then this amount will be equal to 4D because multiplication is simply repeated addition. We can imagine this situation as D+D+D+D, for the 4 weeks he is saving. We can simplify this to 4D in the expression.
Next, the question tells us that this will be 1 dollar more than needed. So, if we want to find the cost, we need to subtract that dollar.
Thus, the final expression is 4D - 1 because this represents 1 dollar less than the money he saves for 4 weeks.
