1 = x^2 - x
x^2-x-1=0
quadratic formula:

the positive root is special because it's equal to the
golden ratio
Answer:
104 in
Step-by-step explanation:
Answer:
length = 1696 m
breadth = 571 m
Step-by-step explanation:
perimeter = 4534 m
let breadth be b
so length = b + 1125 m
so
perimeter of rectangular garden = 2(l+b)
4534 m = 2(b+1125m+b) {substituting the value}
or, 4534 m = 2(2b+1125m)
or, 4534 m = 4b + 2250 m
or, 4534 m - 2250m = 4b
or, 2284m = 4b
or, b = 2284m/4
so, b = 571m
so, l = b + 1125 m
= 571 m + 1125m
= 1696 m
Answer:
1.
Step-by-step explanation:
First find the derivative of sin-1x.
This is a standard derivative and it is 1 /√(1 - x^2)
This is the slope of the graph at x.
Slope at x = 0 = 1 /√(1 - 0^2)
= 1/1 = 1,
