18.84
Step-by-step explanation:
divide 12 by 2 which is 6 then times that by 3.14
Answer:
Vertex : 5
Y - intercept : (0,-4)
Step-by-step explanation:
-4 is on the y-axis.
Vertex is the maximum or the minimum point of the parabola.
Answer:
2
Step-by-step explanation:
Given g(x) = sin(x)-1/cos2(x), we are to find the limit if the function g(x) as g(x) tends to π/2
Substituting π/2 into the function
lim x-->π/2 sin(x)-1/cos 2(x)
= sin(π/2) - 1/cos(2)(π/2)
= 1 - 1/cosπ
= 1- 1/-1
= 1 -(-1)
= 1+1
= 2
Hence the limit of the function h(x) = sin(x)-1/cos2(x) as x--> π/2 is 2
