Answer:
Step-by-step explanation:
In the case of each of the answers listed above, the second derivative is equal to -4 times the function, as required by the differential equation.
For y = 2/3t^3, the second derivative is 4t, not -4y.
For y = e^(2t), the second derivative is 4y, not -4y.
__
The graph shows the sum of the second derivative and 4y is zero for the answers indicated above, and not zero for the other two proposed answers.

Answer:
b.
Step-by-step explanation:
The general form for a circle is:
(x - a)^2 + (y - b)^2 = r^2
where (a, b) is the centre and r = the radius.
So here (a, b) = (5, -9) and r = 12 giving:
(x - 5)^2 + (y - (-9))^2 = 12^2
(x - 5)^2 + (y + 9)^2 = 144.
Y = tan (√ t )
We will use chain rule.
( tan x ) ` = sec² x
( √ t ) ` = 1 / 2√t
y ` = sec² (√ t ) · 1 / 2√t
y` = 1/cos² ( √ t ) · 1 / 2√t
