The answer in scientific notation is: 4.32 x 10^-2
The second and the fourth
Two other ways to write 0.632 is to turn it into a percent. To turn 0.632 into a percent just multiply it by 100. You can do this simply by moving the decimal point to the right twice and adding the percent sign: 63.2%
Another way is by fraction form. To put in in fraction form just look at the decimal and see which is the last place. The last placement it a thousandth. So your denominator is automatically 1000. Then, you look at the decimal and write the decimal and disregard the zero. The fraction you get is 632/1000. Hope this answer helps and mark as brainliest!
Answer:
1) 270 degrees
2) pi/4 rad
Step-by-step explanation:
1.) For which value of theta is sine theta = negative 1?
Given
sintheta = -1
theta = arcsin(-1)
theta = -90degrees
Since sin is negative in the third and 4th quadrant
In the third quadrant, theta = 180 + 90 = 270degrees
In the fourth quadrant, theta = 360 - 90 = 270 degrees
Hence the required value of theta is 270degrees
2) Given the radius of the circle to be 1, the y axis value will also be 1 units
Opposite = 1
adjacent = 1
hyp = √1²+1²
hyp = √2
sin theta = opp/hyp
sin theta = 1/√2
theta = arccsin(1/√2)
theta = 45 degrees
Express in radians
45 degrees = pi/4 radians
Hence the required angle in the first quadrant is pi/4 rad
