←→ is parallel to CD←→. AC¯¯¯¯¯ and BD¯¯¯¯¯ are perpendicular to AB←→ and CD←→ . What is the relationship between AC¯¯¯¯¯ and BD¯¯¯¯¯ ?

Answer:

40

Step-by-step explanation:

divide both by 2

40 percent of 100 is 40

or

80/200 = .4 or .40 which is 40%

Answer:

( z - 5 ) ( z - 5 )

Step-by-step explanation:

z² − 10z + 25

= z² − 5z - 5z + 25

= z ( z - 5 ) - 5 ( z - 5 )

= ( z - 5 ) ( z - 5 )

Answer:

The geometric mean of 125 and 5 is, 25

Step-by-step explanation:

Geometric mean(GM) of two number is given by:

As per the statement:

Given two numbers i.e 125 and 5

then by definition we have;

⇒

⇒

⇒GM = 25

Therefore, the geometric mean of 125 and 5 is, 25

Answer-

The coordinates of D' are (-1, -5)

Solution-

The coordinates of D are (-1, 5).

While reflecting any points across the x-axis with coordinates as (x, y) becomes, (x, -y). i.e sign of y-coordinate changes.

The rule is (x, y) → (x, -y)

Applying so, after reflecting point D, its reflection D' will have coordinates as (-1, -5)

Therefore, the y-coordinate is -5.

The answers are A and B, -5 and -1. Hope this helps!

• Slope Formula:

Step-by-step explanation:

Step 1: Define

Point (1, 9)

Point (6, 34)

Step 2: Find slope m

1. Substitute:                    
2. Subtract:                      
3. Divide:                          

Answer:

The slope is 5

Step-by-step explanation:

so you use formula m= y2-y1/x2-x1 and use 34 as y2, 9 as y1, 6 as x2 and 1 as x1 then plug in numbers when using the formula and do the math and get your slope
