<u>Part 1) </u>

we know that

The Centroid of a Triangle is the centre of the triangle that can be calculated as the point of intersection of all the three medians of a triangle.

The Centroid divides each median into two segments whose lengths are in the ratio 2:1

so

VZ=\frac{1}{3}RV

RV=3VZ

we have

VZ=6\ in

substitute

RV=3*6=18\ in

Find RZ

RZ=\frac{2}{3}RV

RZ=\frac{2}{3}*18=12\ in

therefore

<u>the answer Part 1) is the option C</u>

12\ in

<u>Part 2) </u>

Statements

<u>case A)</u> ∠BEC is an exterior angle

The statement is False

Because, ∠BEC is a internal angle

<u>case B</u>) ∠DEC is an exterior angle.

we know that

An <u>exterior angle</u> is formed by one side of a triangle and the extension of another side

therefore

The statement is True

<u>case C)</u> ∠ABE and ∠EBC are supplementary angles.

we know that

∠ABE+∠EBC=180\° -------> by supplementary angles

therefore

The statement is True

<u>case D) </u>∠BCF and ∠BEC are supplementary angles  

The statement is False

Because

the only way that is true is that the triangle BEC is isosceles and that the ∠BEC is equal to the ∠BCE  

<u>case E)</u> ∠BEC is a remote interior angle to exterior F.∠BCF

we know that

<u>Remote interior angles</u> are the interior angles of a triangle that are not adjacent to a given angle. Each interior angle of a triangle has two remote exterior angles.

In this problem  ∠BEC has two remote exterior angles (∠BCF and ∠EBA)

therefore

The statement is True

Given the center of the circle (-3,4) and a point on the circle (-6,2), (10,4) is on the circle
Anastasy [175]

Answer:

Part 1) False

Part 2) False

Step-by-step explanation:

we know that

The equation of the circle in standard form is equal to

(x-h)^{2} +(y-k)^{2}=r^{2}

where

(h,k) is the center and r is the radius

In this problem the distance between the center and a point on the circle is equal to the radius

The formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

Part 1) given the center of the circle (-3,4) and a point on the circle (-6,2), (10,4) is on the circle.

true or false

substitute the center of the circle in the equation in standard form

(x+3)^{2} +(y-4)^{2}=r^{2}

Find the distance (radius) between the center (-3,4) and (-6,2)

substitute in the formula of distance

r=\sqrt{(2-4)^{2}+(-6+3)^{2}}

r=\sqrt{(-2)^{2}+(-3)^{2}}

r=\sqrt{13}\ units

The equation of the circle is equal to

(x+3)^{2} +(y-4)^{2}=(\sqrt{13}){2}

(x+3)^{2} +(y-4)^{2}=13

Verify if the point (10,4) is on the circle

we know that

If a ordered pair is on the circle, then the ordered pair must satisfy the equation of the circle

For x=10,y=4

substitute

(10+3)^{2} +(4-4)^{2}=13

(13)^{2} +(0)^{2}=13

169=13 -----> is not true

therefore

The point is not on the circle

The statement is false

Part 2) given the center of the circle (1,3) and a point on the circle (2,6), (11,5) is on the circle.

true or false

substitute the center of the circle in the equation in standard form

(x-1)^{2} +(y-3)^{2}=r^{2}

Find the distance (radius) between the center (1,3) and (2,6)

substitute in the formula of distance

r=\sqrt{(6-3)^{2}+(2-1)^{2}}

r=\sqrt{(3)^{2}+(1)^{2}}

r=\sqrt{10}\ units

The equation of the circle is equal to

(x-1)^{2} +(y-3)^{2}=(\sqrt{10}){2}

(x-1)^{2} +(y-3)^{2}=10

Verify if the point (11,5) is on the circle

we know that

If a ordered pair is on the circle, then the ordered pair must satisfy the equation of the circle

For x=11,y=5

substitute

(11-1)^{2} +(5-3)^{2}=10

(10)^{2} +(2)^{2}=10

104=10 -----> is not true

therefore

The point is not on the circle

The statement is false

Length and breadth of a rectangle is 28 and 20 respectively. It's perimeter is ....... *
vampirchik [111]

Answer:

96

Step-by-step explanation:

Because the perimeter of a rectangle is 2 * (length) + 2 * (breadth),

P = 2 * 28 + 2 * 20

P = 56 + 40 = 96
