What is the approximate distance between the points (-5, 1) and (-2, 3) on a coordinate grid? A.7.81 units B.3.61 units C.2.23 u

andrey2020 [161]

The formula for distance between point in a coordinate grid is the following:

$\sqrt{(x2 - x1) {}^{2} + (y2 - y1) {}^{2} }$
Where 1 and 2 stands for the points, so in your case the formula is the following
$\sqrt{( - 2 - - 5) {}^{2} + (3 - 1) }$
$\sqrt{ {3}^{2} + 2 {}^{2} }$
$\sqrt{9 + 4}$
$\sqrt{13} =3.605...$
So your answer is about 3.61

Find a polynomial equation that has roots of -2 and double root 3

lbvjy [14]

Answer:

x³ + 2x² -3x +6

Step-by-step explanation:

We need to find the polynomial whose roots are ,

-2 , √3 and √3.

Say of we have zeroes as , α , β and γ , then the polynomial is ,

=> p(x) = k[ (x - α ) ( x - β) ( x - γ) ]

where k is constant. Substituting the respective values , we have ,

=> p(x) = k [ ( x - (-2)) ( x - √3) ( x -√3)]

=> p(x) = k[ (x+2)(x² - 3)]

=> p(x) = k[ x(x² - 3) + 2(x² - 3) ]

=> p(x) = k[ x³ - 3x + 2x² - 6 ]

=> p(x) = k[ x³ + 2x² - 3x - 6 ]

<h3>Hence the cubic polynomial is x³ + 2x² - 3x + 6 .</h3>

Dvinal [7]

Answer:

Step-by-step explanation:

A tree that is 100 feet tall casts a shadow that is 150 feet long ...

The angle at which the ray of the sun hit the ground is that which has a tangent equal to 100 / 150 or 2/3. This angle is equal to 33.69. Thus, the answer is letter B. 34°
