Do you think a negative number raised to an even power will be positive or negative? Explain.

Tanya [424]

Answer:

A negative number taken to an even power gives a positive result (because the pairs of negatives cancel), and a negative number taken to an odd power gives a negative result (because, after cancelling, there will be one minus sign left over).

In the theory of learning, the rate at which a subject is memorized is assumed to be proportional to the amount that is left to

fiasKO [112]

Step-by-step explanation:

From the statement:

M: is total to be memorized

A(t): the amount memorized.

The key issue is translate this statement as equation "rate at which a subject is memorized is assumed to be proportional to the amount that is left to be memorized"

memorizing rate is $\frac{dA(t)}{dt}$ .

the amount that is left to be memorized can be expressed as the total minus the amount memorized, that is $M-A(t)$ .

So we can write

$\frac{dA(t)}{dt}=k(M-A(t))$

And that would be the differential equation for A(t).
