You can say an object slow down when the acceleration is negative which can be observed on a negative slope during the graph of acceleration, from a position equation lets derive 2 times to attain the acceleration equation
<span>x(t) = 81/2*t^2-3/4*t^4
V(t) = 81X - 3t^3
A(t) = 81 - 9t^2
</span>81 - 9t^2 < 0<span>
t^2 > 9
-3 > t > 3

Answer:
y-2=3(x-8) or y=3x-22
Step-by-step explanation:
Point slope form is y-y1=m(x-x1)
Here, y1 is 2 and x1 is 8 because of the ordered pair given. The slope, m, is 3. When you put those into the equation, you get y-2=3(x-8). Depending on whether you want to simplify that, the answer could also be y=3x-22 (distribute the 3 and you get y-2=3x-24, add the two and voila!) Hope this was useful! :)
If the angles PLN = PNL, that means they are 45 each. A triangle's angles add to 180 and LPN is 90.
Knowing that these angles are equal, we also know that the length of PN is equal to LP because the angle opposite to the two sides are the same. So PN = 12.
If PN is 12, then MP = 17-12= 5.
Then use Pythagorean Theorem to find LM
5^2 + 12^2 = c^2
LM = 13
Use order of operations or PEMDAS
this is order of simplification
work from left to right
Parentahsees (grouping symbols)
Exponents
multiplication or division
addition or subtraction
so
replace a with 1, b=2 and c with -8
now exponents
multiply and divide, working from left to right (remember, division is multiplication by a fraction)
addition and subtraction
The correct answer would be A) 3/4=21/28
Explanation: 3 x 7=21; 4 x 7=28. None of the other answer choices demonstrate a proportion. Hope this helps:)
