Answer:

As you know, g = 9.81 m/s on the surface of the Earth. ... If the action force is the force she exerts downward on the chair, what is the reaction force? ... it take a 10-N force to increase the speed of a 10-kg toy car from 1.00 m/s to 4.00 m/s? ... (DH 32) How many joules of kinetic energy does a .5 kg cart have when it is ...

Darya [45]
Use the compound interest formula: A=P(1+i)^t.

P is the initial amount of the drug, 0.3ml.
i is - 0.0035.
t is in seconds.

You'll get:
A=0.3(1-0.0035)^t.

Sub in any value on t to find out how many ml are left t seconds after injection.

The 0.65 second injection time does not seem to be relevant as the question clearly states that the exponential decay starts AFTER the injection is completed.

Evaluate: a) n!/(n-3)!<br>b) P(6,4)/4!​
telo118 [61]

Step-by-step explanation:

a).

n! is

n(n - 1)(n - 2)(n - 3)(n - 4).........(1)

(n-3)! is

(n - 3)(n - 4)(n - 5)..........(1)

If we divide the two, everything behind (n-3) will just cancel out so we would be left with only

(n)(n - 1)(n - 2)

So the answer to a is

n(n - 1)(n - 2)

b

Permutations formula of P(6,4) is

6!/(6-4)!, or 6!/2!.

\frac{6  \times 5 \times 4 \times 3 \times 2 \times 1}{2 \times 1}  = 360

Then we divide by 4!

\frac{360}{4 \times 3 \times 2 \times 1}  = 15

The answer to b is 15
