Find a point on the y-axis that is equidistant from the points (8, −8) and (1, 1).
artcher [175]

\text{We know that any point on the y-axis is of the form (0, y),}\\&#10;\text{because on y-axis we have x=0.}\\&#10;\\&#10;\text{So let (0, y) be the point on the y-axis that is equidistance from}\\&#10;\text{the points }(8,-8) \text{ and }(1,1)\\&#10;\\&#10;\text{so using the distance formula, we have}\\&#10;\\&#10;\text{Distance between (0, y) and }(8,-8)=\text{Distance between (0,y) and }(1,1)\\&#10;\\&#10;\Rightarrow \sqrt{(0-8)^2+(y-(-8))^2}=\sqrt{(0-1)^2+(y-1)^2}

\Rightarrow \sqrt{64+(y+8)^2}=\sqrt{1+(y-1)^2}\\&#10;\\&#10;\text{Squaring both sides, we get}\\&#10;\\&#10;(\sqrt{64+(y+8)^2})^2=(\sqrt{1+(y-1)^2})^2\\&#10;\\&#10;\Rightarrow 64+(y+8)^2=1+(y-1)^2\\&#10;\\&#10;\Rightarrow 64+(y^2+16y+64)=1+(y^2-2y+1)\\&#10;\\&#10;\Rightarrow y^2+16y+128=y^2-2y+2\\&#10;\\&#10;\Rightarrow y^2+16y-y^2+2y=2-128\\&#10;\\&#10;\Rightarrow 18y=-126\\&#10;\\&#10;\Rightarrow y=\frac{-126}{18}\\&#10;\\&#10;\Rightarrow y=-7

So the point on the y-axis that is equidistant from the points (8,-8) and (1,1) is: (0,-7)

F(x) = x2 + 10<br> What is the average rate of chan<br> hange of f over the interval [-2, -1]?
Readme [11.4K]

The average rate of change is given by [f(b) - f(a)]/(b - a), where a and b represent the interval [a, b].

Let a = -2

Let b = -1

[(-1)^2 + 10 - ((-2)^2 + 10)]/(-1 -(-2))

[1 + 10 - (4 + 10)]/(-1 + 2)

[1 + 10 -4 -10]/(1)

[1 - 4]/(1)

-3/1

Answer: -3
