I'll teach and give you the answer for you problem (5 2/7 −1 1/2 )∙(1− 14/53 )
Convert mixed numbers to improper fractions 5 2/7 = 37/7:
(37/7-1 1/2) * (1- 14/53
Convert mixed numbers to improper fractions 1 1/2 = 3/2:
(37/7-3/2) * (1- 14/53
Join 37/7-3/2 = 53/14
53/14(-14/53+1)
Join 1-14/53 = 39/53
53/14 * 39/53
Cross-Cancel 53:
39/14
Your Answer As A Improper Fraction---> 39/14
Your Answer As A Mixed Number---> 2 11/14
plz mark me as brainliest :)
Answer:
I'm pretty sure figure A is the only one correct and also figure D
Answer:
If you want to draw a perpendicular line from a point on a line, you would measure a 90 degree angle from that point and then draw the line outward.
Explanation
On the other hand, if you wanted to draw a perpendicular line connecting a line and a point off of the line, you would have to connect the point to the location on the line that forms a 90 degree angle.
Both methods involve making a 90 degree angle between two lines. Can you think of any other similarities?
Answer:
The answer is cosx cot²x ⇒ the first answer
Step-by-step explanation:
∵ cot²x = cos²x/sin²x
∵ secx = 1/cosx
∴ cot²x secx - cosx = (cos²x/sin²x)(1/cosx) - cosx
= (cosx/sin²x) - cosx
Take cosx as a common factor
∴ cosx[(1/sin²x) - 1] ⇒ use L.C.M
∴ cosx[1-sin²x/sin²x]
∵ 1 - sin²x = cos²x
∴ cosx(cos²x/sin²x) = cosx cot²x
