Answer:
y = x² - 2x - 3
Step-by-step explanation:
y + 4 = C(x - 1)²
To determine C, use x = 4, y = 5
5 + 4 = C(4 - 1)²
9 = 9C, C = 1
y + 4 = (x - 1)² = x² - 2x + 1
y = x² - 2x - 3

y=0x-3 because the slope is undefined, so it is 0 and the y intercept is -3 because it goes across the y axis.
Answer:
Total cost of cementing the path = Rs. 17,000.
Step-by-step explanation:
Let the square garden be PQRS
Let the region inside the garden (PQRS) be KLMN.
<u>Given the following data;</u>
Length of sides of PQRS = 90m
Width of path = 5m
Cost = Rs. 10 per m²
Area of PQRS = 90 * 90
Area of PQRS = 8100m²
<em>To find the area of KLMN;</em>
KL = KN = 90 - (5 + 5)
KL = KN = 90 - 10
KL = KN = 80m
Area of KLMN = KL * KN
Substituting into the equation, we have;
Area of KLMN = 80 * 80
Area of KLMN = 6400 m²
Area of path = Area of PQRS - Area of KLMN
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>
