Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given the diameter of the circle 'd' = 58cm
The radius of the circle 'd' = 2r

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 !
Answer:
x=4.375
Step-by-step explanation:
-3(2x-7)+5=2x-9
-6x+21+5=2x-9
-6x+26=2x-9
-6x-2x+26=2x-2x-9
-8x+26=-9
-8x+26-26=-9-26
-8x=-35
-8x/-8=-35/-8
x=4.375
Answer:
This question requires us to change the subject of a formula. This can be achieved by following the order of operations in reverse. First, isolate the terms with our variable of interest, x:
ax - bx = z - y
Then, we take x out as it is being multiplied to both a and b:
x(a - b) = z - y
Dividing (a - b) on both sides, we get:
x = (z - y) / (a - b)
Thus, the answer is x= z-y/a-b
