The vertices of triangle ABC are A(5,2), B(-1,-6) and C(1,5). If Triangle DEF is similar to Triangle ABC and AB/DE=5, what could

astraxan [27]

Answer:

D(-5,3) and E(-5,1)

Step-by-step explanation:

|AB|² = (-1-5)² + (-6-2)²

|AB|² = 36 + 64

|AB|² = 100

|AB| = 10

AB/DE = 5

|DE| = 10/5 = 2

D(-5,3) and E(-5,1)

|DE|² = (-5+5)² + (3-1)²

|DE|² = 4

|DE| = 2

6t-10is the awsner. If s is the number of nautical miles separating the ships, express s in terms of t(the number of hours after 12 noon). I formed the equation s squared to the second power equals (12t) squard to the second power + (10 - 16) squared to the second power

The Quadratic Formula, x equals negative b plus or minus the square root of b squared minus 4 times a times c, all over 2 times

DedPeter [7]

Answer:

The correct option is 2 .

Therefore ,the missing denominator of the solution. 4 plus or minus the square root of 2, all over is  2 . 

$x=\dfrac{4\pm\sqrt{2}}{2}$

Step-by-step explanation:

For a Quadratic Equation ax² + bx + c = 0

By Formula Method we get

$x=\dfrac{-b\pm\sqrt{b^{2}-4ac}}{2a}$

So we have Quadratic Equation is 2x² - 8x + 7 = 0

On Comparing we get

$a=2\\b=-8\\c=7$

Substituting a , b, c values we get

$x=\dfrac{-(-8)\pm\sqrt{(-8)^{2}-4(2)(7)}}{2(2)}\\\\x=\dfrac{8\pm\sqrt{64-56}}{4}\\\\x=\dfrac{8\pm\sqrt{8}}{4}\\\\x=\dfrac{8\pm2\sqrt{2}}{4}\\\\x=2(\dfrac{4\pm\sqrt{2}}{4})\\\\x=\dfrac{4\pm\sqrt{2}}{2}$

Therefore ,the missing denominator of the solution. 4 plus or minus the square root of 2, all over is  2 .

The lines p and q intersect at point O. What is the value of x? Enter your answer in the box. x =

Romashka-Z-Leto [24]

Answer:

x = 16

Step-by-step explanation:

The two angles are vertical angles, which means they are equal

3x-3 = 2x+13

Subtract 2x from each side

3x-3-2x =2x-2x+13

x-3 =13

Add 3 to each side

x-3+3 =13+3

x = 16

Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle:

MA_775_DIABLO [31]

Answer:

The length of the side BC is 6 units

Step-by-step explanation:

Distance Between two Points in the Plane

Given two points A(x1,y1) and B(x2,y2), the distance between them is:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We need to calculate the distance between B(7,5) and C(7,-1):

$d=\sqrt{(7-7)^2+(5+1)^2}$

$d=\sqrt{36}$

d=6

The length of the side BC is 6 units
