The answer is C
first draw line y=x that's simply line that increases from left to right and has slope of one and goes thru origin.
you now see its reflected
Answer:
Answer:
B only
Step-by-step explanation:
In A and in C, only the angles of
one triangle are congruent to the
corresponding angles of the other
triangle. That proves similar triangles but
not necessarily congruent triangles.
Definition of congruent triangles:
Two triangle are congruent if all angles
of one triangle are congruent to all
corresponding angles of the other
triangle and all sides of one triangle are
congruent to all corresponding sides of
the other triangle.
That happens only with the triangles in B.
Answer: B only
The slope-intercept form: y = mx + b
(m - slope, b - y-intercept)
We have y = -2. It's the slope intercept form where m = 0 and b = -2.
y = -2 → y = 0x - 2
Answer:
The other leg X = 8m
Step-by-step explanation:
As per Pythagorean theorem-
Square of hypotenuse = sum of square of other two sides of the triangle
Substituting the given values in above equation, we get -
m
The other leg X = 8m
Answer:
solution:
If ║v(t)║= 1, for all t >= a, then the parameter t corresponds to arc length.
║v║=║r'║*║v║=√4t^2+16t^2+64t^2=√84t=2√21t is not equal to 1,
so it doesn't use arc length as a parameter.
Consider s = √21t
r(s) =(s/√21, 2s/√21, 4s/√21) for √21 <=s<=16√21
║r'(s)║=(1/√21)*√1+4+16
= 1
so now it does use arc length as its parameter.
