Answer:
(C)
Step-by-step explanation:
Given the distance, d(t) of a particle moving in a straight line at any time t is:

To find an expression for the instantaneous velocity v(t) of the particle at any given point in time, we take the derivative of d(t).

The correct option is C.
Answer:
The number of ways in which the digits can be assigned in the color wheel can be determined by the permutation of 8 taken 4 since it is in circular formation and whichever comes first is not important.
number of ways = 9P4 = 3024 ways
15 = 3² +2(7-4)
____
The above expression includes operations of
- exponentiation
- subtraction
- multiplication
- addition
The exponent is 2.
I know the value of this expression is 15 because
- I designed the expression to have a value of 15
- I get a value of 15 when I evaluate the expression
- A reliable on-line calculator also gets a value of 15 when it evaluates the expression
24000-260=23740
So the answer is:
The large adult elephant is 23,740 more pounds than the baby elephant.
