Answer:

Step-by-step explanation:

The point-slope form of the equation that describes the line with a slope of <em>m</em> that contains the point (x₀, y₀) is: y - y₀ = m(x - x₀)

m = - 3

(1, 2) ⇒ x₀ = 1, y₀ = 2

Therefore:

y - 2 = -3(x - 1)

Compute the radius of the largest circle that is internally tangent to the ellipse at $(3,0),$ and intersects the ellipse only a

Artyom0805 [142]

Answer: radius of the largest circle is Zero.

Step-by-step explanation: A circle can't fit into an ellipse with such coordinate (3,0). What that coordinate means is that the ellipse lies along the x axis 3unit from the origin along the x axis and 0 unit from the origin along the y axis. At which no circle can fit in.

Moreso, the the coordinates at which the circle intercepts the ellipse as to be uniform not (3,0).

A circle as a constant radii coordinate on both axis.

I believe you can now see why my answer is Zero.

Which equation correctly shows how to determine the distance between the points (9, –2) and (6, 3) on a coordinate grid?

dybincka [34]

Hint: $\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 9}}\quad ,&{{ -2}})\quad 
% (c,d)
&({{ 6}}\quad ,&{{ 3}})
\end{array}\qquad 
% distance value
d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}$

According to the Rational Root Theorem, which of the following values is a possible rational root of the polynomial p(x)=x2+3x+1

slava [35]

Answer:

C. -2

Step-by-step explanation:

Since the leading coefficient is 1 and rational roots are of the form ...

±(divisor of the constant)/(divisor of the leading coefficient)

all of the possible rational roots must be whole number diviors of 12. The only one on the list is -2.
