You can use the distance formula for this:
√(x2-x1)²+(y2-y1)²
so you'll get √(1-4)²+(11-7)² = √(-3)²+(4)² = √9+16 = √25 = 5 and 5 is your answer
Answer:
The answer is option 2, by simplifying 9 to 3² to make both powers base 3 and subtracting the exponents.
Step-by-step explanation:
You have to make the expressions into the same base :

Next, you have to apply Indices Law :




It is 15 degrees. A right angle is 90 degrees, so to find one sixth of that, you divide 90 by 6 (which is the same thing as multiplying 90 by one sixth). You get 15.
Y + 4/9 = 2/3
Let's convert 2/3 into 6/9 so it will be easier to subtract.
Y + 4/9 = 6/9
Subtract 4/9 on both sides.
Y = 2/9 Hope this helps!
