Answer:
A. The curve is a parabola with a vertex at (3,-4) and is traced from left to right for increasing values of t.
Step-by-step explanation:
x = 3 + t
y = t² − 4
Eliminating the parameter:
t = x − 3
y = (x − 3)² − 4
This is an upwards parabola with a vertex at (3, -4).
x = 3 + t, so as t increases, x increases.
So the curve is traced from left to right.
Assuming that (-3x + 4) and (2x + 7) are two legs of a rectangle, you can find the perimeter like this: P = 2*length + 2*width.
P = 2*(-3x + 4) + 2*(2x + 7)
P = -6x + 8 + 4x + 14
P = -2x + 22
Hope this helps! :)
Answer: 12 inches
Step-by-step explanation:
Answer:
s - 8
Step-by-step explanation:
TO find the function rule, substitute (s-2) in place of v. Then simplify.
h(v) = v - 6
h(s - 2) = (s - 2) - 6
h(s - 2) = s - 8
