The value of (f - g)(x) is as follows:
(f - g)(x) = 4x³ + 6x² - 7x - 1
<h3>How to solve functions?</h3>
f(x) = 4x³ + 6x² - 3x - 4
g(x) = 4x - 3
Let's find the function:
(f - g)(x)
Therefore,
(f - g)(x) = 4x³ + 6x² - 3x - 4 - ( 4x - 3)
Hence, let's open the bracket
(f - g)(x) = 4x³ + 6x² - 3x - 4 - 4x + 3
Let's combine like terms
(f - g)(x) = 4x³ + 6x² - 3x - 4x - 4 + 3
Therefore,
(f - g)(x) = 4x³ + 6x² - 7x - 1

Answer:
<h2> 55.10min </h2>
Step-by-step explanation:
This problem is on the mensuration of flat shapes.
given that the initial radius before Cody alerted the fire department is
10 ft
Then we can calculate the area of the fire as
Area= πr^2
Area=3.142*(10)^2
Area=3.142*100
Area=314.2ft^2
Also, given that the area of the circular fire has grown to 45401 square feet
let us solve for the radius first, then we can calculate the time taken since the radius was increasing by 2 ft/min
let the radius of the large fire be R
45401=πR^2
R^2=45401/3.142
R^2=14449.714
square both sides we have
R=√14449.714
R=120.2ft
The difference between the radius of the initial fire and the large fire is
R-r=120.2-10
=110.2ft
Hence the time taken can be calculated as
time= 110.2/2
time=55.10min
Answer:
1/2 or 50-50
Step-by-step explanation:
