I think the answer is number two
Answer:
300%
Step-by-step explanation:
$2.25 divided by $0.75 = 3 (new price divided by old price)
This means the price has gone up by 300% as $0.75= 100%
(I’m not sure I explained this very clearly, if you want me to rewrite it just say!)
Answer:
B. y = tan x and C. y = cot x
Step-by-step explanation:
Range:
range is defined as the set of values that any given function y=f(x), can take for which the x values are defined. It is the value that y can take for the values of x.
Given:
From the given options
the range of tanx and cotx are all real numbers
as the period of tanx and cotx are π
where as range of secx is all real numbers except π/2 + n*π i.e.
(-∞ , -1] U [1 , + ∞)
And range of cscx is all real numbers except n*π i.e.
(-∞ , -1] U [1 , + ∞)
So from the given option:
option B and C are correct while A and D are not !
-9 to the second power will most likely be 81. A negative x a negative equals a positive. Hope this helped.
