Step-by-step explanation:
2.9 hours = 174mins
174 mins = 4.9miles
1 miles = 1740/49 mins
8.73 miles = 310.0mins (1dp)

Answer:
<em>(f-g)(x)=x+14</em>
Step-by-step explanation:
<u>Operations with Functions</u>
Given two functions f(x) and g(x), the following operations are defined:
(f+g)(x)=f(x)+g(x)
(f-g)(x)=f(x)-g(x)
(f*g)(x)=f(x)*g(x)
(f/g)(x)=f(x)/g(x)
We have f(x)=3x+10 and g(x)=2x-4. Use the second formula to find
(f-g)(x)=(3x+10)-(2x-4)
Operating:
(f-g)(x)=3x+10-2x+4
Joining like terms:
(f-g)(x)=x+14
Answer:
10 seconds
Step-by-step explanation:
we are given the height (s) which is 1600ft. and the formula—where t is time in seconds— t= 1/4
, so we can plug 1600ft in for s and solve:
t= 1/4
t= 1/4(40)
t= 10 seconds
The greatest common factor of 30, 60, and 75 is 15.
15 x 2 = 30
15 x 4 = 60
15 x 5 = 75
Net working capital is the sum of assets and liabilities.
Beginning of year,
net working capital = 316-220=$96
At end of year,
net working capital = 469-220=$249
change in networking capital = new capital - old capital
=249-96
=$153
