Okay, so YZ = 3 cm.  You have XM correct. And YM = 0.5.

Now, you have the midpoint M at the correct spot.

Use Pythagorean's theorem o find the length of AB.  a² + b² = c²   a=6,  b=8.

6² = 36   8² = 64    36 + 64 = 100      AB = 10!

If AB = 10   then AM = 5    MB also = 5

If B is the midpoint of AC,  C would be 12 rows down from A, and 16 columns to the right. The last spot where the line intersects.

There are your answers!

What is m<br> A.55°<br> B.58°<br> C.122°<br> D.125°
Andreyy89

Answer: k = 55 degrees

Step-by-step explanation:

to find J, subtract 122 from 180, you get 58. The total number of degrees is 180. Since L is given as 67, and 67+58=125. Simply subtract 125 from 180 which is 55 degrees

the sum of the reversed number and the original number is 154. Find the original number, if the ones digit in it is 2 less than
VladimirAG [237]

Answer:

The number is 86

Step-by-step explanation:

Let the number be  xy, then the reverse is yx

The sum of the reversed number and the original number is 154,

\implies (10x+y)+(10y+x)=154

We simplify this to get:

\implies 11x+11y=154....eqn(1)

If the ones digit in it is 2 less than the tens digit, then

y=x-2....eqn(2)

Putt equation (2) in (1)

\implies 11x+11(x-2)=154

\implies 11x+11x-22=154

\implies 11x+11x=154+22

\implies 22x=176

\implies x=8

Put x=8 in the second equation:

y=8-2=6

The original number is 86

F(x) = 3 sin x + 3 cos x
Darina [25.2K]
F ( x ) = 3 sim x + 3 cos x
f ` ( x ) = 3 cos x - 3 sin x
f `` ( x ) = - 3 sin x - 3 cos x = - 3 ( sin x + cos x )
The inflection points:
- 3 ( sin x + cos x ) = 0
sin x + cos x = 0
sin x = - cos x / : cos x
tan x = - 1
x 1 = 3π / 4
x 2 = 7π / 4
The function is concave up when f``(x) > 0
- 3( sin x+ cos x ) > 0
sin x + cos x < 0
tan x < - 1
f is concave up for:
x ∈ ( π/2, 3π/4 ) ∪ ( 3π/2, 7π/4)
f is concave down for: 
x ∈ ( 0, π/2 ) ∪ ( 3π / 4, 3π/2 ) ∪ ( 7π / 4, 2 π ).
