Answer:

x = 9.2 cm

Step-by-step explanation:

We can use a trigonometric relation in order to find the correct answer. In this case, since we know the opposite side to the angle and we want to know the adjacent side, the most convenient function is the tangent:

tan(40°) = opposite/adjacent  or  opposite = tan(40°)*adjacent

Substituting the adjacent side value and the tan(40°), we get:

x = 0.839 * (11 cm) = 9.229 cm (approximately 9.2 cm)

Therefore, the answer is 9.2 cm.

The number of adults who attend a county fair (measured in hundreds of people) is represented by the function a(d)=−0.3d2+4d+9 ,
Lesechka [4]

Given is the function for number of adults who visit fair at day 'd' after its opening, a(d) = −0.3d² + 4d + 9.

Given is the function for number of children who visit fair at day 'd' after its opening, c(d) = −0.2d² + 5d + 11.  

Any function f(d) to find excess of children more than adults can be written as follows :-  

f(d) = c(d) - a(d).

⇒ f(d) = (−0.2d² + 5d + 11) - (−0.3d² + 4d + 9)

⇒ f(d) = -0.2d² + 0.3d² + 5d - 4d + 11 - 9

⇒ f(d) = 0.1d² + d + 2
