Answer:
Options c and d
Step-by-step explanation:
Given is a graph with period pi.
ii) The graph is discontinuous
iii) x intercepts are say (a) units to the right of y axis and repeats for every interval of pi.
Fix the function
a) y = sinx cannot be this graph because sinx is a continuous graph
b) y =cosx cannot be this graph because cosx is a continuous graph
e) y = sec x is undefined for the range (-1,1) since the given graph is defined in this interval, secx is not answer.
f)y = csc x is undefined for the range (-1,1) since the given graph is defined in this interval, cscx is not answer.
c) y=tanx is a discontinuous graph at x = odd multiples of pi/2
Hence the given graph can be of the form y =- tan (2x+a) which shows reflection over y axis,
d) y = cotx can also be this graph with adjustments for period and horizontal shift.
So answers are c and d
Answer:
C = 7pi units or approximately 21.98 units
Step-by-step explanation:
The circumference is given by
C = pi * d
We are given the diameter of 7
C = 7pi
We can approximate pi by 3.14
C = 7 *3.14
C =21.98 units
Answer:
x are in all real number
Step-by-step explanation:
4k-32=-32+4k
there are infinity solution for that because there are away equal each other
Answer:
gradient = 
Step-by-step explanation:
Calculate the gradient m using the slope formula
Solution:
Let 
and 
.
m = 
So, the gradient of the line is - 1/2.
Hope this helps!
