Answer:
<u>B. (3,25)</u>
Step-by-step explanation:
x = level of the video game
y = number of points
At level 1, a player has 5 points.
At level 2, the player has 5 + 10 = 15 points
Therefore, we can use the function notation this way:
f(x) = 5x + 10
<u>The only ordered pair given that is from this function is:</u>
<u>B. (3,25)</u>
<u>f(3) = 5 * 3 + 10 </u>
<u>f(3) = 15 + 10 = 25</u>
The remaining three don't represent this function.
What is 0.00340.78 correct to 3 significant figures?
a significant fugure is when the number lean solething ,so its can anyone except 0
so if we are reducing 0.00340.78 to 3 significant number
first we have to look for the significant nulber ,which are 3,4,7,8
so the answer can be 0.0034.7
hopefully this helps

x = 45°
Step-by-step explanation:
Since this is an isosceles triangle, that means that x, and the angle opposite from x, are the same. We take 135° and subtract that from 180°. That gives us 45°. Since the angle opposing x is 45°, then x is 45° as well.

(a-b) X (a+b)
= aXa - bXa +aXb -bXb (distributing)
Now, cross product of a vector with itself = 0
so, aXa = 0, bXb = 0
Also, aXb = - bXa
so,
(a-b) X (a+b) = 0 + aXb + aXb + 0
= 2aXb
hence, proved :)
