Hey There

☆— — — — — — — — — — — — — — — — — — — — — — — — — — — —☆

The answer to this is:

a=2, b=4, c=3

d=2, e=3

\frac{1}{2} : \frac{3}{4} = \frac{1}{2}  * \frac{4}{3} = \frac{1}{a} * \frac{b}{c} \\

\frac{1}{2} * \frac{4}{3} =\frac{2}{3} =\frac{d}{c}

Thus, the answer is:

a=2, b=4, c=3  

d=2, e=3

By the Segment Addition Postulate, SAP, we have

XY + YZ = XZ

so

YZ = XZ - XY = 5 cm - 2 cm = 3 cm

10.

M is the midpoint of XZ=5 cm so

XM = 5 cm / 2 =  2.5 cm

11.

XY + YM = XM

YM = XM - XY = 2.5 cm - 2 cm = 0.5 cm

12.

The midpoint is just the average of the coordinate A(-3,2), B(5,-4)

M = (A+B)/2 = \left( \dfrac{-3 + 5}{2}, \dfrac{2 + -4}{2} \right)

Answer: M is (1,-1)

You'll have to plot it yourself.

13.

For distances we calculate hypotenuses of a right triangle using the distnace formula or the Pythagorean Theorem.

AB^2 =(5 - -3)^2 + (-4 - 2)^2 = 8^2 + 6^2 = 100

Answer: AB=10

M is the midpoint of AB so

Answer: AM=MB=5

14.

B is the midpoint of AC.   We have A(-3,2), B(5,-4)

B = (A+C)/2

2B = A + C

C = 2B - A

C = ( 2(5) - -3, 2(-4) - 2 ) = (13, -10)

Check the midpoint of AC:

(A+C)/2 = ( (-3 + 13)/2, (2 + -10)/2 ) = (5, -4) = B, good

Answer: C is (13, -10)

Again I'll leave the plotting to you.

Solve: -4.878-(-8.96)=
Pepsi [2]
-4.878-(-8.96) can be changed to -4.878 + 8.96 because when you subtract a negative it becomes a positive so the answer would be 4.082 or B

Answer:

  D.  tan(-π/6)

Step-by-step explanation:

The tangent function is periodic with a period of π, so ...

  tan(5π/6) = tan(5π/6 ± kπ) . . . for any integer k

For k = -1, we have ...

  tan(5π/6) = tan(5π/6 -π) = tan(-π/6)
