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)

Jk=6x, kl=3x, and jl=27
sweet [91]

I am going to assume these are points across the same line. (line segments)

If so, then jk + kl = jl

If jk is 6x and kl is 3x, we can solve for x.

6x + 3x = 27 (note we subbed 27 in for jl)

9x = 27 (divide both sides by 9 to leave on x on the left)

x = 3

CHECK! sub 3 in for x in the original problem.

6 (3) + 3 (3) = 27

18 + 9 = 27

Yes! It checks. x = 3
