Answer:

8√2

Step-by-step explanation:

A = ( -2 , 2 ) and B = ( 6 , -6 )

→ State the distance formula

√ ( ( x₂ - x₁ )² + ( y₂ - y₁ )² )

→ Assign values

x₂ = 6 , x₁ = -2 and y₂ = -6, y₁ = 2

→ Substitute into the formula

√ ( ( 6 - (-2) )² + ( -6 - 2 )² )

→ Simplify

√ ( 8 )² + ( -8 )²

→ Further simplify

8√2

Answer: Its 11.31 or \sqrt{128}

Step-by-step explanation:

So the distance formula is d=√((x_2-x_1)²+(y_2-y_1)²).

Point A is (-2,2) and Point B is (6,-6).

So then we replace the numbers

d=√(6+2)²+(-6-2)²

d=√(8)²+(-8)²

d=√64+64.

d=√128.

d=11.31

What is the polynomial function of least degree whose only zeros are -3, ,-2, and 4 ?
victus00 [196]

Answer: (x³ - 2x² - 11x + 12)

Step-by-step explanation:

Recall that zeroes can be transformed into factors by subtracting them from x. This gives us the following factors:

(x - 1)(x + 3)(x - 4)

Now, if you multiply the first two factors together, you get the following:

(x² + 2x - 3)

Multiply that by the last factor, (x - 4), and you get this:

(x³ + 2x² - 3x - 4x² - 8x + 12)

This can be simplified:

(x³ - 2x² - 11x + 12)

And there's your final answer. Hope this helped! (x³ - 2x² - 11x + 12)
