Answer:
-1
Step-by-step explanation:
dy/dt = y² − 1 = (y + 1) (y − 1)
At t = 0, y = 0, and dy/dt = -1. Therefore, y is initially decreasing.
As y decreases, dy/dt increases. When y = -1, dy/dt = 0 and changes signs from negative to positive.
As y increases above -1, dy/dt again becomes negative. So y continues to approach -1 as t approaches infinity.
Answer with Step-by-step explanation:
We are given an expression:
28 + x - 2n + 7 - n - 5x + 4
We have to find its equivalent expression
On combining the like terms of the above expression
28+4+7+x-5x-2n-n
= 39-4x-3n
= -3n-4x+39
According to Tyrone the equivalent expression was:
-3n - 5x + 39 + x
The error Tyrone made was:
A. Tyrone neglected to combine the x terms
1. 200 Parsecs, 652.312 Light years 2. 8 Parsecs, 26.09248 Light years ; Use this formula, p=1/P(parallax), to solve the equation. Then multiply 3.26156 (light years per parsec) by the number of parsecs.
1. p= 1/0.005 = 200*3.26156 = 652.312
200 Parsecs, 652.312 Light years
2. p=1/0.125 = 8*3.26156 = 26.09248
8 Parsecs, 26.09248 Light years
You would get back $1
$9.99-$1.50= $8.49 <--- 15% off
$8.49x.06= .51 cents <--- Taxes
$8.49+.51<--cents= $9 <--- Total cost of the T-shirt
