Answer:

B, y+6=-4(x-2)

Step-by-step explanation:

since you need a perpendicular line, the slope has to be the opposite reciprocal. 4/1 or 4 is the reciprocal of 1/4, and to make it the opposite reciprocal, you need to change it to negative. for the coordinates (-2,-6), you need to use it in the equation y-y1=m(x-x1)

Olin [163]

Answer:

Area covered by the fences will be 16.1 unit²

Step-by-step explanation:

Let the first parabola is represented by the function f(x) = 6x²

and second parabola by g(x) = x² + 9

point of intersection of the graphs will be determined when f(x) = g(x)

6x² = x² + 9

5x² = 9

x² = 1.8

x = ± 1.34

Now we will find the area between these curves drawn on the graph.

Area = $\int_{-1.34}^{1.34}[f(x)-g(x)]dx=\int_{-1.34}^{1.34}[6x^{2}-(x^{2}+9)]dx$

= $\int_{-1.34}^{1.34}(5x^{2}-9)dx$

= $[\frac{5}{3}x^{3}-9x]_{-1.34}^{1.34}$

= $[\frac{5}{3}(-1.34)^{3}-9(-1.34)-\frac{5}{3}(1.34)^{3}+9(1.34)]$

= $[-4.01+12.06-4.01+12.06]$

= 16.1 unit²

The domain is ?<br> The range is ?

DIA [1.3K]

This is a quadratic equation, which is also a polynomial. Polynomials all have the domain (-infinity, +infinity).

As for the range: You can see from the graph that the smallest y-value is -2. Thus, the range is [-2, infinity).
