Answer:
a.) -1 < x < 5
b.) x <= 1
Step-by-step explanation: Domain is the independent variable (x).
For both question a and b, make sure that the number under the square root does not end up being negative. And the denominator of the fractional number is not equal to zero when variable x is being substituted for any value.
a.) y = √ x + 1 /√ 25 − x^2
Domain : -1 < x < 5
That is the minimum value for x is 0 and the maximum value is 4
b. f(x) = (√ 1 − x ) ln x
Domain : x <= 1
That is, x is less than or equal to 1
The maximum value for x is 1. x can be
1, 0, -1, -2, -3, ..........
Answer:
1/6, now can you answer my question
Step-by-step explanation:
Answer:
The height of the tree is 16.67 feet.
Step-by-step explanation:
Refering the figure, let the height be "x" feet.
It is evident that triangles ABC and triangle EDC are similar.
(as both man and tree are perpendicular to the ground)
thus, 
hence,
Thus, 
.
Rhett did because if u look at the graph it lands on -4
