I need help with someone explaining how to find the range of this! This course didn’t explain anything!

zaharov [31]

Answer:

$(-infinity,3)$ , D

Step-by-step explanation:

3 if x is greater than or equal to 1 is nothing. That leaves us with $h(x)=2x+1$ if x<1. If you substitute in 1 for x, you get 3, but of course that isn't possible, so the range is $(-infinity,3)$ , which is D.

can someone please help me out with this problem ? i been trying to do this for like 2 days now and i still don’t get it .. also

kotykmax [81]

Answer:

Step-by-step explanation:

the Pythagorean theorem is

c is the hypotenuse which is the side opposite of the right angle

plug the numbers into the Pythagorean theorem

$x^2+(\sqrt{26})^2=13^2$

when squaring a square root, just take the number in the radical and get rid of the radical

$x^2+26=169$

subtract 26 from both sides

$x^2=$ $143$

find the square root of 143

143 is prime so it can just be written as

$x=\sqrt{143}$
