This means Square root (^1/2). this is kind of hard to read. anyways. 32^(1/2) separates into 4^(1/2) and 8^(1/2), which further separates into 4^(1/2) and 2^(1/2), root 4 becomes 2, their are two root 4's, so you get 2 x 2, and you are left with 2^(1/2) now why go to all this trouble. because now you can multiply the 4 you created (2x2) times, the 7... giving you 28*2^(1/2) now subtract it from the the other one with root 2. -5*2^(1/2), giving you 23*2^(1/2)-...idk what that last bit is. if its a odd number then this is the end of the problem, if you can get it to root 2. then do that and simplify.
Answer:
Similar but not congruent
Step-by-step explanation:
They look to be the same shape, but they aren't the same exact size so they cant be congruent. To be congruent they would have to be the same size and shape, but they are only the same shape, different sizes.
- Correct. This is the distance around the circle, aka the perimeter.
- False. Going from center (O) to the point A is the radius, which is half the diameter. Answer: radius
- Correct. The diameter is a chord that goes through the center. A chord is any segment where the endpoints are on the circle's edge.
- Correct. There are three radii shown in this diagram. The other radius is OC. Segment BC is a chord that is neither a diameter nor a radius.
In short, all you need to do is change "diameter" to "radius" in question 2. Other than that, you're perfect.
Answer:
the first one, x, is (n-6)/4
Step-by-step explanation:
x+(x+1)+(x+2)+(x+3)=n
4x+6=n
4x=n-6
x=(n-6)/4
First, find the slope of this line, if possible. Recall that slope = m = rise / run.
We see that x does not change:
the distance from 2 to 2 is 0, and thus the slope of this line would be undefined, due to division by zero. Thus, the line is vertical. if it passes thru (2,3), then the equation of the line can be taken to be x=2.
