Answer:
D) 
Step-by-step explanation:
Acceleration is the derivative of velocity, which is the derivative of position, so we must differentiate the function twice:
Position of Particle: 
Velocity of Particle: 
Acceleration of Particle: 
After
seconds, the acceleration of the particle is 
9514 1404 393
Answer:
- common denominator: (x² -4)
- simplified complex fraction: (2x +1)/(9 -2x)
Step-by-step explanation:
It is helpful to remember the factoring of the difference of squares:
a² -b² = (a -b)(a +b)
__
Your denominator of (x² -4) factors as (x -2)(x +2). You will note that one of these factors is the same as the denominator in the other fraction.
It looks like you want to simplify ...

She is incorect because
(a+b)^2 =a^2 +b^2+ 2ab
a + b
____###### If we sqare this will get:
____######
|.a^2|. ab |
|___ |######
# #. #
# ab #. b^2 #
#___ ######
Answer:
These are the forms to write the ratio. Please read the explanation.
<u>a. 3/4</u>
<u>b. 3:4</u>
<u>c. 3 ÷ 4</u>
<u>d. Ratio of 3 to 4</u>
Step-by-step explanation:
1. Let's check the information given to resolve the question:
Number of 13-year olds = 36
Number of 14-year olds = 48
2. Writing the ratio of 13-year-olds to 14-year olds in all three forms:
We can say that there are:
36/48 13-year olds to 14-year olds but we notice immediately that we can simplify that ratio this way:
36/48 = 18/24 (Dividing by 2) = 9/12 (Dividing by 2 again) = 3/4 (Dividing by 3)
We can conclude that the ratio of 13-year-olds to 14-year olds is 3/4 and we can write it these ways:
<u>a. 3/4</u>
<u>b. 3:4</u>
<u>c. 3 ÷ 4</u>
<u>d. Ratio of 3 to 4</u>
