Answer:
7x²-12x-10
Step-by-step explanation:
(5x²-8x+1) + (2x²-4x-11)
combine like terms
7x²-12x-10
Answer:
Radius is <u>2.8</u> Circumference is <u>17.584 or 17.6 Rounded to the nearest Tenths </u>
Step-by-step explanation:
1. Find circumference with the Formula <u>C=πd</u>
C=3.14 x 5.6
<u><em>C=17.584 or 17.6 Rounded to the nearest Tenths </em></u>
2. Radius is Always half of the Diameter.
5.6/2 = 2.8
<em><u>2.8 is your radius.</u></em>
3. If you want to check you work try the formula C=2πr to see if things checks out.
C=2 x 3.14 x 2.8
<u><em>C= 17.584 or 17.6 Rounded to the nearest Tenths </em></u>

The velocity of the particle is given by
Since and , we get
Similarly, the position function is obtained via
We know and we're told that , so
making the answer A.
The value of A is 9. This is because 40-13= 27
3x?=27 3x9=27
