qaws [65]3 years ago
7 0

Answer:

range {3, 5, 6, 7 }

Step-by-step explanation:

to find the range substitute each value of x from the domain into f(x)

f(- 3) = -(- 3) + 4 = 3 + 4 = 7

f(- 2) = - (- 2 + 4 = 2 + 4 = 6

f(- 1) = - (- 1) + 4 = 1 + 4 = 5

f(1) = - 1 + 4 = 3

range y ∈ { 3, 5, 6, 7 }

Find the area of the figure. PLEASSEEEEEEEE!!!!!!!!
allochka39001 [22]

Given:

side length = 6 ft

To find:

The area of the figure

Solution:

Area of the square = side × side

                               = 6 × 6

Area of the square = 36 ft²

Diameter of the semi-circle = 6 ft

Radius of the semi-circle = 6 ÷ 2 = 3 ft

Area of the semi-circle = \frac{1}{2} \pi r^2

                                      $=\frac{1}{2} \times 3.14 \times 3^2

Area of the semi-circle = 14.13 ft²

Area of the figure = Area of the square - Area of the semi-circle

                              = 36 ft² - 14.13 ft²

                              = 21.87 ft²

Area of the figure = 21.9 ft²

The area of the figure is 21.9 ft².

Step-by-step explanation:

Given that Young millennials, adults aged 18 to 34, are viewed as the future of the restaurant industry. During 2011, this group consumed a mean of 192 restaurant meals per person (NPD Group website, November 7, 2012).

It is claimed that due to poor economy this average might have been subjected to a change.
