If your question is "what time was it before the elapsed time", then the answer will be 9:38. All you have to do is to deduct the time by 30 minutes based on your clock, and you will be able to get the answer right away. Also, if you add 9:38 by 30 minutes, you will get 10:08 as well.
Answer:
1/2, since 1 whole is 18/18 and 1/2 is equal to 9/18
Step-by-step explanation:
Answer:
Function 1
Step-by-step explanation:
The y-intercept is the y-value when the x-value = 0.
In Function 1 the y-intercept is 1 because (0, 1).
In Function 2 the y-intercept is -3 because x = 0 y = -3.
And 1 > -3 so Function 1 is the answer.
Answer: Vertical line x = 1
<u>Step-by-step explanation:</u>
(1, 1) (1, 2) (1, 3) (1, 4)
Notice that the x-value for each coordinate is 1.
The line is a vertical line (up & down) through x = 1
A trig identity is <span>asinucosu=<span>a/2</span>sin(2u)</span>So you can write your equation as<span>y=sin(x)cos(x)=<span>1/2</span>sin(2x)</span>Use the crain rule here<span><span>y′</span>=<span>d/<span>dx</span></span><span>1/2</span>sin(2x)=<span>1/2</span>cos(2x)<span>d/<span>dx</span></span>2x=cos(2x)</span>The curve will have horizontal tangents when y' = 0.<span><span>y′</span>=0=cos(2x)</span>On the interval [-pi, pi], solution to that is<span><span>x=±<span>π4</span>,±<span><span>3π</span>4</span></span></span>
