In △ M N O , points R and T are the midpoints of their respective sides. MT and OR intersect at point C.

hichkok12 [17]

Answer:

3. 15 units

Step-by-step explanation:

When medians intersect, the point of intersection divides the median into parts in the ratio 2:1. That is ...

OC : CR = 2 : 1 = 4 units : 2 units . . . . . . OR = (4+2) units = 6 units

MC : CT = 2 : 1 = 6 units : 3 units . . . . . . MT = (6+3) units = 9 units

The sum of lengths OR + MT is ...

6 units + 9 units = 15 units

Anybody know the right answer?

qwelly [4]

Quadrant I : cot(x) > 0 → -cot(x) < 0

Quadrant II : cot(x) < 0 → -cot(x) > 0

Quadrant III : cot(x) > 0 → -cot(x) < 0

Quadrant IV : cot(x) < 0 → -cot(x) > 0

------------------------------------------------------------------

$a)\ \left(\dfrac{11\pi}{6},\ -\sqrt3\right)\\\\\dfrac{11\pi}{6}\in\text{Quadrant IV, then -cot(x)} > 0,\ \text{we have}\ -\cot\dfrac{11\pi}{6}=-\sqrt3 < 0$

Answer: a)

$b)\\\dfrac{2\pi}{3}\in\text{Quadrant II},\ -\cot(x) > 0,\ \text{we have}\ \dfrac{\sqrt3}{3} > 0\\\\c)\\\dfrac{5\pi}{4}\in\text{Quadrant III},\ -\cot(x) < 0,\ \text{we have}\ -1 < 0\\\\d)\\\dfrac{4\pi}{3}\in\text{Quadrant III},\ -\cot(x) < 0,\ \text{we have}\ -\dfrac{\sqrt3}{3} < 0$

We know that one answer is only true, so we did not check the correctness of the cotangent value, only to the number sign

4 5/7 subtract 1 6/7 is what in simplest form please show your work

BaLLatris [955]

Change the mixed fractions to an improper fraction.
4 5/7 = 32/7
1 6/7 = 13/7

Now you can easily subtract since both fractions have common denominators
32/7 - 13/7
(Think: 32 - 13 = 19)

Change the improper fraction to a mixed fraction
19/7 = 2 5/7

Answer: 2 5/7

Hope I helped =)
