Answer:
The value of <em>x </em>is equal to 26 cm.
Step-by-step explanation:
We can use the Pythagorean Theorem to solve this problem.







Answer:
= 50
Step-by-step explanation:
Answer: f(x)=
has all real value as its domain.
Explanation: since, we have three functions f(x)=
,
while g(x) and p(x) are line segments.
Now, g(x) is a function by a line segment which passes through two points (-1.8,-3) and ( 1,3.8).
Thus it is clear that its domain will be the ends points. so domain of the function g(x) will be [-1.8, 3.8] which is the subset of real numbers set (R).
Similarly, domain of function p(x) will be [1.7, 1], which is also the subset of R.
But, when we talk about f(x) it contains all the possible value of x. Thus we can say that
has R as its domain.
Answer: Domain: x=-2. Range: -2<=y<1
Step-by-step explanation:
Domain: The line is only on one x-point and that is x=-2.
Range: The line is ranging form -2 to 1. However, y=1 is not included on the line but y=-2 is. Hence, the range is notated as -2<=y<1.
