Hi there!
The correct answer for you is 270.88.
To round to the hundreth's place (.0<u>1</u><u />), you need to take the number in the thousand's place (.00<u>1</u>), and determine if the number needs to go up or down.
If the number in the thousand's place is <u>greater</u> than 4, then the number goes up.
360.72<u>7</u> --> This means that the hundreth's number goes up to 3.
If the number in the thousand's place is <u>lesser</u> than 5, then that number stays the same.
89.85<u>2</u> --> This means that the hundreth's number stays the same.
After you round, then just subtract:
360.73 - 89.85 = 270.88.
I hope this helps!

Answer:
y = -2x^2(x - 3)
Step-by-step explanation:
<em><u>Preliminary Remark</u></em>
If a cubic is tangent to the x axis at 0,0
Then the equation must be related to y = a*x^2(x - h)
<em><u>(3,0)</u></em>
If the cubic goes through the point (3,0), then the equation will become
0 = a*3^2(3 - h)
0 = 9a (3 - h)
0 = 27a - 9ah
from which h = 3
<em><u>From the second point, we get</u></em>
4 = ax^2(x - 3)
4 = a(1)^2(1 - 3)
4 = a(-2)
a = 4 / - 2
a = -2
<em><u>Answer</u></em>
y = -2x^2(x - 3)
So 1 would be 5r+20 and then the second one would be
84 is no less than 7 times K, 84 divided by 7= 12,
K=12
