Find the distance between the two points rounding to the nearest tenth (if necessary).

iris [78.8K]

Step-by-step explanation:

Distance between (−3,6) and (−9,−2):

$(x_1, y_1)$

= coordinates of the first point

= (-3,6)

$(x_2, y_2)$

= coordinates of the second point

= (-9,-2)

$d = \sqrt{(x_2 - {x _1) }^{2} + (y_2 - {y _1) }^{2}}$

$d = \sqrt{ (- 9 - ( - 3) {)}^{2} + ( - 2 + 6 {)}^{2} }$

$d \: = \sqrt{ (- 6 {)}^{2} +( 4 {)}^{2} }$

$d = \sqrt{36 + 16}$

$d = \sqrt{52}$

$d = \sqrt{13 \times 2 \times 2}$

$d = 2 \sqrt{13}$

7. Jena has a triangular garden with a perimeter that can be represented by 25r ^ 2 - 9r + 14 . The sum of two sides of the gard

galben [10]

Answer: $15r^2-21r+5$

Step-by-step explanation:

Given: Perimeter of triangular garden = $25r^2 - 9r + 14$

The sum of two sides of the garden = $10r^2 + 12r + 9$

Perimeter is the sum of all sides of a triangle.

Third side = Perimeter of triangular garden - sum of two sides of the garden

$=25r ^ 2 - 9r + 14-(10r ^ 2 + 12r + 9)\\\\=25r ^ 2 - 9r + 14-10r ^ 2 - 12r - 9\\\\=15r^2-21r+5$

The expression represent the third side = $15r^2-21r+5$ .

How can $54,000 be invested part at 8% annual simple Interest and the remainder at 10% annual simple interest so that the intere

Nastasia [14]

Answer:

0.08x = $5400-0.1x Add 0.1x to both sides of the equation.

0.18x = $5400 Divide both sides by 0.18

x = $3000 and $54000-$3000 = $24000

$3,000 is invested at 8%

$2,400 is invested at 10%
