Answer:
The constant speed with Ed is travelling is 60 mile per hour
Step-by-step explanation:
Given as :
The distance cover to travel from Jefferson to Holden is (D1) 250 miles
The distance cover to travel from Holden to Paxton is (D2) 50 miles
Total time taken to complete entire journey = T = 5 hours
Let The constant speed of Ed = S mph
Time =
Or, Time =
+
Or, 5 hour =
+
Or, 5 × S = 250 + 50
So, 5 × S = 300
∴ S =
I.e S = 60 mph
Hence , The constant speed with Ed is travelling is 60 mile per hour Answer
Answer:
(3,0),(2,0)
Step-by-step explanation:
The answer will be F^-1= x/4
The domain of a function f(x)/m(x) = 1/√x(x² - 4) is (0, ∞) - {0, 2, -2} for other function is shown in the solution.
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have:
f(x) = 1/√x
m(x) = x² - 4
Domain of f(x)/m(x):
f(x)/m(x) = (1/√x)/(x² - 4)
f(x)/m(x) = 1/√x(x² - 4)
The denominator cannot be zero:
√x(x² - 4) ≠ 0
x(x - 2)(x+2) ≠ 0
x ≠ 0, 2, -2
and x > 0
Domain of f(x)/m(x) is: (0, ∞) - {0, 2, -2} or 
Domain of f(m(x)):
f(m(x)) = 1/√(x² - 4)
x² - 4 > 0
Domain: 
Domain of m(f(x)):
= ((1/√x)² - 4)
Domain: 
Thus, the domain of a function f(x)/m(x) = 1/√x(x² - 4) is (0, ∞) - {0, 2, -2} for other function is shown in the solution.
