Answer:
Domain: [-8. 4]
General Formulas and Concepts:
<u>Algebra</u><em><u> </u></em><u>I</u>
- Domain is the set of x-values that can be inputted into function f(x)
- Interval Notation
Step-by-step explanation:
From the graph, we can see that our x-values span from -8 to 4. Since both are closed dot, they are inclusive in the domain:
[-8. 4] or -8 ≤ x ≤ 4
Answer:
Total cost of cementing the path = Rs. 17,000.
Step-by-step explanation:
Let the square garden be ABCD
Let the region inside the garden (ABCD) be WXYZ.
<u>Given the following data;</u>
Length of sides of ABCD = 90m
Width of path = 5m
Cost = Rs. 10 per m²
Area of ABCD = 90 * 90
Area of ABCD = 8100m²
<em>To find the area of WXYZ;</em>
WX = WZ = 90 - (5 + 5)
WX = WZ = 90 - 10
WX = WZ = 80m
Area of WXYZ = WX * WZ
Substituting into the equation, we have;
Area of WXYZ = 80 * 80
Area of WXYZ = 6400 m²
Area of path = Area of ABCD - Area of WXYZ
Area of path = 8100 - 6400
Area of path = 1700 m²
Total cost of cementing the path = Area of path * cost
Total cost of cementing the path = 1700 * 10
<em>Total cost of cementing the path = Rs. 17,000</em>
Answer:
Step-by-step explanation:
2x+4 = 7x-1
4+1 = 7x - 2x
5 = 5x
x = 5/5
x = 1
