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

1. Which of the following questions has a constant of
garik1379 [7]

Answer:

In B)  y = x/7 , the constant of proportionality is 7.

Step-by-step explanation:

Two quantities X and Y are said to be in proportion if and only if

X = kY   or, \frac{X}{Y}  = k,

where k =  Proportionality Constant.

Here, 7 is the constant of proportionality. Then,

A .   y = 14x

here, \frac{y}{x}  = 14  ≠ 7

B .   y = x/7

here, \frac{x}{y}  = 7  = constant of proportionality .

C.   y = x

here, \frac{y}{x}  = 1  ≠ 7
