You have to remember P.E.M.D.A.S. when doing problems like this.
Drew used PEMDAS so we know he isn't wrong. However, Sam didn't use PEMDAS. She multiplied 2&5 instead of raising 5 to the second.
The correct answer for Sams' problem would be 30.
Hope this helps! :)

If RB = 4 and OR = 3, then OB = 5 7 2√3

pogonyaev

The complete question in the attached figure

we know that

triangle OBR is a right triangle
so
applying the Pythagorean theorem

OB²=OR²+RB²----> OB²=3²+4²-----> 25
OB=√25-----> OB=5 units

the answer is
OB=5 units

For what value of \$x\$ is the function \$\\frac{1}{x-2}\$ not defined?

natima [27]

for the value of $x=2$ we have the function f(x) = 1/(x-2) or $f(x)=\frac{1}{x-2}$ as undefined or not defined .

Step-by-step explanation:

Function undefined: A function is undefined when it gives results which are not defined for example , infinity .

Here we have , Function f(x) = 1/(x-2) or $f(x)=\frac{1}{x-2}$ . We need to find a value of for which this is not defined . Let's find out:

We can clearly see that it's a fractional function with numerator as 1 and denominator as x-2 . For a fractional function to be undefined it's denominator must be zero i.e. x-2 = 0 or $x-2=0$

⇒ $x-2=0$

⇒ $x-2+2=0+2$

⇒ $x=2$

Therefore, for the value of $x=2$ we have the function f(x) = 1/(x-2) or $f(x)=\frac{1}{x-2}$ as undefined or not defined .
