Answer:
2+x
Step-by-step explanation:
Sum= addition
If the number is not provided we always include a variable and the most common one is X never use t, o, i, l, because you might confuse yourself because they look like numbers when they are variables.
Answer:
it is orthogonal
Step-by-step explanation:
if you do the dot product.
U dot V = 0
(3 times 0) + (0 times 6 ) = 0
0 + 0 = 0
therefore it is orthogonal.
the dot product says that if u dot v equals zero, then you can say that it is orthogonal.
Answer:
y = 1/2x
Step-by-step explanation:
The slope is the rise (up) over run (left or right depending on if the number is negative) between points. So the next point on the graph is up 5 and over 10. this simplified is 1/2. Then you put this into y=mx which is y=1/2x
Given that the triangle is an isosceles right angled triangle, then the value of x will obtain using the Pythagorean theorem, given by:
c^2=a^2+b^2
where
c is the hypotenuse, a and b are the legs
thus
x^2=12^2+12^2
x^2=144+144
x^2=288
hence
x=√288
x=√(2×144)
x=2√12
