Answer:
The correct answer is option C
(f o g)(x) = 3x² + 7x + 2
Step-by-step explanation:
<u>Points to remember</u>
<u>Composite functions</u>
Let f(x) and g(x) be the two functions then (f o g)(x) can be written as
(f o g)(x) = f(g(x))
<u>To find the value of (f o g)(x)</u>
Here f(x) =x + 2 and g(x) = 3x² + 7x
(f o g)(x) = f(g(x))
= f(3x² + 7x)
= 3x² + 7x + 2
Therefore the correct answer is option C
(f o g)(x) = 3x² + 7x + 2
Given:
The scale of a map is 
.
The distance between two buildings is 60 miles.
To find:
The distance between the given building on the map.
Solution:
We have,
It means, 80 miles in real life = 
on the map.
1 mile in real life = 
on the map.
60 mile in real life = 
on the map.
= 
on the map.
= 
on the map.
Therefore, the buildings are apart on the map.
Answer:
15.01
Step-by-step explanation:
From the diagram above, the following were obtained:
Adj = 7
0 = 65°
Opp =?
Tan0 = Opp /Adj
Tan65° = Opp/ 7
Cross multiply
Opp =7 x Tan65°
Opp = 15.01
Answer:
Inverse.
Step-by-step explanation:
Inverse trigonometric functions.
e. g. tan-1 x means 'the angle whose tangent is x'.
They are also called arcsin, arccos and arctan.
