Answer:
39.6
Step-by-step explanation:
Given in the right angled triangle above are:
Ѳ = 49°,
Adjacent length = 26
Hypotenuse length = x
To find x in the right angled triangle given above, apply the trigonometric formula, cos Ѳ = adjacent length/hypotenuse length
Thus,

Multiply both sides by x



Divide both sides by 0.6561 to find x




x = 39.6 (to nearest tenth)
20%
Because Suppose x% of 20 is 4
That is
x100×20=4
or
x5=4
—> =4×5=20
So 20% of 20 is 4

Answer:
k
Step-by-step explanation:
k
The correct answer is A.
lets discard the other options:
For B:
B is always positive, but f(x) is not, so B graph is not the answers
For C:
C is always positive too, so it cannot be the desire graph.
For D:
D is always negative, but we know that x exponent 3 is positive for all positive numbers,
