Help me answer these questions please 15, 19 and 20 please​
SpyIntel [72]

Answer:

15) K'(t) = 5[5^(t)•In 5] - 2[3^(t)•In 3]

19) P'(w) = 2e^(w) - (1/5)[2^(w)•In 2]

20) Q'(w) = -6w^(-3) - (2/5)w^(-7/5) - ¼w^(-¾)

Step-by-step explanation:

We are to find the derivative of the questions pointed out.

15) K(t) = 5(5^(t)) - 2(3^(t))

Using implicit differentiation, we have;

K'(t) = 5[5^(t)•In 5] - 2[3^(t)•In 3]

19) P(w) = 2e^(w) - (2^(w))/5

P'(w) = 2e^(w) - (1/5)[2^(w)•In 2]

20) Q(W) = 3w^(-2) + w^(-2/5) - w^(¼)

Q'(w) = -6w^(-2 - 1) + (-2/5)w^(-2/5 - 1) - ¼w^(¼ - 1)

Q'(w) = -6w^(-3) - (2/5)w^(-7/5) - ¼w^(-¾)

What is 4/9 - (-2/9)
Citrus2011 [14]

Hello!


\frac{4}{9}-\frac{2}{9}

First you had to used apply rule -(-b)=b

\frac{4}{9}+\frac{2}{9}

Since the denominators are equal to it should be combine by the fractions.

\frac{4+2}{9}

Then add 4+2=6

\frac{6}{9}

\frac{4}{9}-\frac{-2}{9}

Finally you had to cancel by the common factor of 3.

=Answer--->\frac{2}{3}

Hope this helps! And thank you for posting at here on Brainly. And have a great day! -Charlie :)

Is 9999 in the sequence n²+2n?​
Tamiku [17]

Answer:

No

Step-by-step explanation:

To find out, all we need to do is plug in 9999 into the sequence.

9999 = n^2 + 2n

By completing the square, we get (n+1)^2 = 1001. 1001 is not a perfect square, which means that 9999 is not in the sequence.

hope this helped! :)
