X,y another way to remember it is d,r. x is domain y is range.
9 because 16 plus 9 is 25 and 21 plus 9 is 30. now you have 25/30
Now you have to simplify:
25 divided 5 is 5 and 30 divided 5 is 6. So 5/6
To get the resultant magnitude and direction of the forces we need to separate the force into its x and y components. For the x components it is the sum of 2000cos(30) and 900cos(45), which is 2368.4469 N. For the y components it will be the sum of 2000sin(30) and -900sin(45), the value for the second force is negative because it is pointing downwards, their sum would be 363.6038 N. The magnitude for the resultant force can be determined using the pythagorean theorem R=sqrt(2368.4469^2 + 363.6038^2) while its direction is found using tan^-1(363.6038/2368.4469). The final answer would be 2396.1946 N with an angle of 8.7279 degrees from the right side of x axis.
The answer would be D: an infinite number, because you can put as far as numbers can go, which is infinite.
Hello! What we need to do first in this kind of problem is multiply the numbers at be beginning of those notations. In this case, those numbers are 6.3 and 8.4. 6.3 * 8.4 is 52.92. We'll come back to this number in a bit. Now, let's worry about the exponents. When it comes to simplifiying scientific notations by multiplying, we need to add the exponents together. In this case, those are 8 and -3. 8 + (-3) is 5. Going back to 52.92, that number is greater than 10, so this will not work in scientifc notation. A number beign multiplied by a power of 10 is supposed to be greater than or equal to 1, but less than 10. We can make that number become less than 10 by moving the decimal to the left once to get 5.292. That works. But we're not done, now we must add 1 into the exponent, which is 5. 5 + 1 is 6. We can now write this in scientific notation:
5.292 * 10^6
There's our answer! That would be 5,292,000 in standard form, because 10^6 is 1,000,000. The notation simplified is 5.292 * 10^6.
