The verticles of triangle A are (-1,3) B (7,9) and C (15,-3) Find the coordinates of the intersection of the medians.
please help

Answers

Answer 1

Step-by-step explanation:

Coordinates of A≡(−1,3)

Coordinates of B≡(7,9)

Coordinates of C≡(15,-3)

The median through the vertex C will meet at the mid point of AB.

Coordinate of mid-point on AB=[(-1+7)/2 , (3+9)/2]= (3,6)

Now,

Length of median through vertex C= Distance between (15,-3) and (3,6)

Therefore,

Length of median = √(3-15)²+(6-(-3))²=√144+81=15unit

Hence the length of median through the vertx C is 15 units.

Natasha is wrapping gifts for the holidays to donate to a local community center. Natasha has 240 square feet of wrapping paper. If Natasha can wrap 8 gifts with 15 sq feet of paper; how many gifts can she wrap in total?

Answers

Answer:

Natasha can wrap 128 gifts in total

Step-by-step explanation:

Let us use the ratio method to solve the question

∵ Natasha has 240 square feet of wrapping paper

∵ Natasha can wrap 8 gifts with 15 square feet

→ By using the ratio method

→ Gift : square feet

→ 8 : 15

→ x : 240

→ By using cross multiplication

∵ x × 15 = 8 × 240

∴ 15x = 1920

→ Divide both sides by 15

∵ x = 128

∵ x represents the number of gifts

∴ Natasha can wrap 128 gifts in total

Answers

Answer:

Input --- Output

1 ------------ 4

6 ------------9

8--------------11

Step-by-step explanation:

Given

Rule:

Output = Input + 3

Required

Complete the table

Represent the input with x and the output, y

So, the rule becomes

[tex]y = x + 3[/tex]

When Input = 1

[tex]x = 1[/tex]

[tex]y = x + 3[/tex]

[tex]y = 1 + 3[/tex]

[tex]y = 4[/tex]

This means:

Output = 4

When Input = 6

[tex]x = 6[/tex]

[tex]y = x + 3[/tex]

[tex]y = 6+3[/tex]

[tex]y = 9[/tex]

This means:

Output = 6

When output = 11

[tex]y = 11[/tex]

[tex]y = x + 3[/tex]

[tex]11 = x + 3[/tex]

[tex]x = 11 -3[/tex]

[tex]x = 8[/tex]

This means

Input = 8

So, the complete table is:

Input --- Output

1 ------------ 4

6 ------------9

What is the quotient of
(x^3+3x^2-4x– 12) (x^2+5x+6)?

O x + 2
O X-2
OX-8
Ox+8

Answers

Answer:

B) X-2

Step-by-step explanation:

The quotient of given polynomials division is (x-2). Therefore, option B is the correct answer.

What is a quotient?

A quotient is a quantity produced by the division of two numbers or two terms. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division, or as a fraction or a ratio.

The given polynomials are (x³+3x²-4x-12) and (x²+5x+6)

Here, (x³+3x²-4x-12) can be written as

x²(x+3)-4(x+3)

= (x+3)(x²-4)

= (x+3)(x+2)(x-2)

Now, (x²+5x+6) can be written as

x²+3x+2x+6

= x(x+3)+2(x+3)

= (x+3)(x+2)

So, (x+3)(x+2)(x-2)/(x+3)(x+2)

= (x-2)

Therefore, option B is the correct answer.

2p - q=2

Answers

Answer:

p = -1 q = -4

Step-by-step explanation:

a system of eq and solve for p and q ??? can do :)

Eq. 1) 8p + 2q = - 16

Eq. 2) 2p - q = 2

use Eq .2 and solve for q

2p - 2 = q

plug into Eq.1 with q

8p +2(2p - 2) = - 16

8p +4p -4 = -16

12p = - 12

p = -1

plug -1 into Eq. 1 for p and solve for q

8(-1) + 2q = - 16

-8 + 2q = - 16

2q = -8

q = -4
