question no.1
here, f (2) is given so
f (x)= x-4
f (2)=2-4
f (2)=-2
so ,the functional value f (x)= -2
1 yard = 3 feet
2.5×18=45 feet
45÷3= 15 yards
Answer:

Step-by-step explanation:
Given:
Distance for north side = 7 miles.
Distance for east side = 24 miles.
We need to find the displacement.
Solution:
Figure shows Point A is starting point and AB = 7 miles is North side distance and BC = 24 miles is east side distance and AC is shown as displacement.
Using Pythagoras theorem to find displacement (AC).

Substitute AB = 7 and BC = 24 in above equation.




Therefore, displacement of the car 
290, 9 - 0 = 9

The man’s original salary was 100%. when increased by 10% , it becomes 110% which is $154 000.
so,
110% -> 154 000
1% -> $1400
100% -> $1400 x 100
= $140 000
