Answer:
15/8
Step-by-step explanation:
tangent = opposite side over adjacent side.
AB= opposite side 15
BC= hypotenuse 17
CA=adjacent 8
in this case it will be 15/8
No it is not a real number
Answer:
the volume of cylinder = πr²h
h = 5cm
r = 6cm
volume = π × 6² × 5
= π × 6 × 6 × 5
= 180πcm³
Answer:
The interval of increase of g(x) is
.
Step-by-step explanation:
The interval of increase occurs when first derivative of given function brings positive values. Let be
, the first derivative of the function is:


The following condition must be met to define the interval of increase:

The first term is always position due to the quadratic form, the second one is a first order polynomial and it is known that positive value is a product of two positive or negative values. Then, the second form must satisfy this:

The solution to this inequation is:

Now, the solution to this expression in interval notation is: 
Answer:
A = bh = (17 km)(11 km) = 187 km^2
