Answer:
domain: x>3/5
Step-by-step explanation:
First we need to derive our function g(x) to get a new function g'(x)
To do this we will have to apply chain rule because we have an inner and outer functions.
Our G(x) = square root(3-5x)
Chain rule formula states that: d/dx(g(f(x)) = g'(f(x))f'(x)
where d/dx(g(f(x)) = g'(x)
g(x) is the outer function which is x^1/2
f(x) is our inner function which is 3-5x
therefore f'(x)= 1/2x^(-1/2) and f'(x) = -5
g'(f(x)) = -1/2(3-5x)^(-1/2)
Applying chain rule then g'(x) = 1/2 (3-5x)^(-/1/2)*(-5)
But the domain is the values of x where the function g'(x) is not defined
In this case it will be 3-5x > 0, because 3-5x is a denominator and anything divide by zero is infinity/undefined
which gives us x >3/5
Answer: 58.1 pounds
Step-by-step explanation:
Use proportion to solve peroblem.
30:249=7:x
30x=249*7
x=249*7/30
x=58.1 pounds
Answer:
ACB
Step-by-step explanation:
Answer:
x = 6
Step-by-step explanation:
An angle bisector divides the segments on either side of it so they are proportional. That is ...
x/12 = 5/10
x = 12(5/10) = 6 . . . . . multiply by 12
