Answer:
<u><em>B: 6 root 2</em></u>
Step-by-step explanation:
this is a right angled triangle having two sides perpendicular and base equal to 6cm
Using the Pythagorean theorem
(Hypotenuse)² = (perpendicular)² + (base)²
c²= (6)²+ (6)²= 36+36
c= √72= √36*2= 6√2= 6 root 2
The volume of a sphere is equal to (4/3)pi*r^3
The volume of your sphere is then (4/3)*pi*r^3 = (4/3)*3.14159265*18^3 = 24429.024 cubic units. That is not one of the answer choices. The closest choice appears to be D.
Multiply tan(26°1') by 205 to find h; then, divide 205 from h to see if the answer is tan(26<span>°1). If it is, the answer is correct; if not, try again- - perhaps you typed in the numbers wrong.</span>
Answer:
<em>f(g(2))=7</em>
Step-by-step explanation:
<u>The Composite Function</u>
Given f(x) and g(x) as real functions, the composite function 
is defined as:
It can be found by substituting g into f.
The given functions are:
It's required to find f( g( 2 ) )
Find g(2):
Operating:
g(2)=1
Now find f(1):
Thus:
f( g( 2 ) )=7
The answer is D............
