take the number to the right of the underlined digit. if its 4 or less, the digits of the underlined one to the left stay the same, while the digits on the right are turned into 0's.
I'll do a few to help you out:
1. *1*60,656 = 200,000
2. *1*49,590 = 100,000
3. 117,*8*21 = 117,800
Answer:

Answer:
Equal the gradient of the given points & of some arbitrary point
Step-by-step explanation:
The gradient of the line = 
Select some arbitrary point 
on that line and rewrite the relationship for the gradient with either point (given) and then equal it to what we just calculated.
I assume you're asked to solve
4 cos²(<em>x</em>) - 7 cos(<em>x</em>) + 3 = 0
Factor the left side:
(4 cos(<em>x</em>) - 3) (cos(<em>x</em>) - 1) = 0
Then either
4 cos(<em>x</em>) - 3 = 0 <u>or</u> cos(<em>x</em>) - 1 = 0
cos(<em>x</em>) = 3/4 <u>or</u> cos(<em>x</em>) = 1
From the first case, we get
<em>x</em> = cos⁻¹(3/4) + 2<em>nπ</em> <u>or</u> <em>x</em> = -cos⁻¹(3/4) + 2<em>nπ</em>
and from the second,
<em>x</em> = <em>nπ</em>
where <em>n</em> is any integer.
Answer:
quadrant 1 - (2,4)
quadrant 2 - (-3,4)
quadrant 3 - (-1, -5)
quadrant 4 - (6, -1)
Step-by-step explanation:
quadrant one consists of both x and y being positive.
quadrant two being the x is negative but the y is negative.
quadrant 3 has its x and y both negative.
finally, quadrant 4 has its x positive, but y is negative.
