<h2>Answer</h2>
<h2>Explanation</h2>
Remember that the square root function is not defined, in the set of real numbers, for negatives values, so its radicand (the thing inside the square root) must be zero or bigger than zero. In other words, to find the domain of a square root function, you should set the thing inside the radical bigger or equal to zero and solve for x. Let's find the domain of each one of our functions:
For
The thing inside the square root is 
, so we are setting that bigger or equal than zero and solve for x to find the domain of the function:
domain
For 
domain
For 
and 
domain
As you can see, the only one that has the domain is the first choice.
1 meter=100 centimeters
14 meters=100*14=1400
I multiplied by 100 because I wanted to convert meters to centimeters, so I can compare the numbers.
140 cm<1400 cm
1400 cm=14 meters, and 14 meters wins!
Answer:
no
Step-by-step explanation:
We can use the Pythagorean theorem to check
a^2 +b^2 = c^2
11^2+13^2 = 17^2
121+169 =289
410 does not equal 289
This is not a right triangle
Answer:
f(5) = 136.71875
Step-by-step explanation:
f(5) if f(1)=3.5 and f(x+1)=5\2 f(x)
f(2) = (5/2)* f(1) = (5/2)* 3.5 = 8.75
f(3) = (5/3)*f(2) =(5/2) * 8.75
f(4) = (5/3)*f(3) =(5/2)*(5/2) * 8.75
f(5) = (5/3)*f(4) = (5/3)*(5/2)*(5/2) * 8.75
f(5) = (5/2)^4 * 3.5 = (625/16) * 3.5 = 136.71875
f(5) = 136.71875
