Answer:
You count how many significant figures there are and because it's division you see which one has the least amount. 1.3 only has two significant figures so the answer will only have 2 sig figs. So, 21.3 divided by 1.3 equals 16.385 but the answer is 16 because you only include 2 sig figs because that's how many are in 1.3. 21.3/1.3=16

Answer:
sin²Ф
Step-by-step explanation:
I doubt that you actually meant "cos 0" ... that has a value of 1.
If you meant (1-cos Ф)(1+cos Ф), then this product is 1 - cos²Ф.
That, in turn, is equal to sin²Ф
Step-by-step explanation:
Line 1 is a horizontal line so the equation of the line for line 1 is Y = 8 Line 2, first solve the slope of the line using points ( -4 , -5) and ( 0, -2) M = (y1 – y2) / (x1 – x2) M = ( -5 – ( -2)) / ( -4 – 0) M = ¾ Since its y intercept is at ( 0,-2) B = -2 Y = ¾ x -2 For c and d you should give a point at which the line is perpendicular or parallel
I think that's how to tell someone, right?
