The definition of the given piecewise function is:

  • y = x^3  - 3, x \leq 2
  • y = x^2 + 6, x > 2

<h3>What is a piecewise function?</h3>

A piecewise function is a function that has different definitions, depending on the input.

In this problem, for x until 2, the function is the cube function shifted down 3 units, hence the definition is:

y = x^3  - 3, x \leq 2

For x greater than 2, the function is the square function shifted up 6 units, hence the definition is:

y = x^2 + 6, x > 2

The equation of a circle is (x + 6)^2 + (y - 4)^2 = 16. The point (-6, 8) is on the circle.
pantera1 [17]

Answer:

y = 8 is the equation of tangent.

Step-by-step explanation:

The equation of the tangent to the circle at (-6,8) is of the form:

y = mx + c

where m is the slope of the tangent and c is the y-intercept.

The point (-6,8) lies on the circle and the tangent line as well.

Hence (-6,8) satisfies the line equation:

8 = m(-6) + c ⇒ c-6m = 8 -------------1

We know that slope of two perpendicular lines are related as:

m_{1}\times m_{2}=-1

At any point on the circle, the normal line at a point is always perpendicular to the tangent line at that point.

Hence :

m_{normal} \times m_{tangent}=-1

We can find the slope of the normal at point (-6,8) as it passes through the centre of the circle (-6,4) by using the two-points formula for slope.

m=\frac{y_2-y_1}{x_2-x_1}

         =\frac{8-4}{-6+6}

          = ∞

Slope of the normal is infinity and hence slope of tangent is -1/∞ = 0

Hence m=0

Putting m=0 in equation 1 we get:

c = 8

The equation of tangent line at (-6,8) is:

y = 8

juin [17]

Answer:

6 - yup        7 - nope

Step-by-step explanation:

If the triangle satisfies the pythagoreon theorem, then it is a right triangle

so 6 is a yeah

then for 7, the hypotunese always is greater than the legs in a right triangle, so 7 is no
