The slope of CD is

m = \dfrac{6 - -4}{2 - 0} = 5

The slope of the perpendicular bisector is the negative reciprocal,

n = -1/m = - \dfrac 1 5

The perpendicular bisector passes through M, the midpoint of CD

M =( (0+2)/2, (-4 + 6)/2) = (1, -1)

So point slope form for the perpendicular bisector is

y - -1 = - \frac 1 5(x - 1)

Solving for y gives slope intercept form.

y = - \frac 1 5 x - \frac 4 5

Not sure how to type that without spaces; we didn't have online homework back then.

Answer: y=(-1/5)x-4/5

(6+√-64)(3-√-16) Multiply. This is urgent, please explain this to me!
romanna [79]

Answer:

50

Step-by-step explanation:

\sqrt{-64} and \sqrt{-16} can be expressed in complex form, with \sqrt{-1} = i

\sqrt{-64} = \sqrt{64(-1)} = \sqrt{64} × \sqrt{-1} = 8i

\sqrt{-16} = \sqrt{16(-1)} = \sqrt{16} × \sqrt{-1} = 4i

the factors can then be expressed as

(6 + 8i)(3 - 4i) ← expand using FOIL

= 18 - 24i + 24i - 32i² [ i² = (\sqrt{-1} )² = - 1 ]

= 18 - 24i + 24i + 32 ← collect like terms

= 18 + 32 + 0

= 50

Forty-six students go on a field trip. The students are divided into groups of 7 students. How many groups of 7 will there be?
Greeley [361]

Answer:

6

Step-by-step explanation:

Given that :

The school children are going for a school field trip. There are total forty - six number of students for the field trip.

They are asked to form groups of seven students in a group.

Therefore they will form = $\frac{46}{7}$

                                      = 6.5

Therefore there will 6 number of groups having 7 students. And the remaining  4 students will form another group.

So there will be 6 groups of seven in each group.

Draw scalene triangle ABC and extend side BC to the right of vertex C.
Doss [256]
Mark Brainliest please


See the image for the drawing
Let’s say the side BC is extended till D

1) measure of angle ACD = 105° ( angle ACD is exterior angle)
45 + 60 = 105
2) I found the answer by adding the values of Angle A and Angle B or by using the exterior angle property.
3) I observed that exterior angle property can be used here. Exterior angle property is that an exterior angle of a triangle is equal to the sum of the opposite interior angles.
