Answer:

$356.25 earned in interest, 2856.25 Total.

Step-by-step explanation:

2.85% of 2500 is 71.25. Multiply that by the time (5 years) and get 356.25 (this is the amount of interest earned)

add that to the original amount. (this is the amount in the account now)

The population of a city increases by 4000 people each year. In 2025, the population is projected to be 450,000 people. What is
luda_lava [24]
P = 390,00 + 4000x

450,000 people - (15years x 4000) = 390k in 2010
 
15 years is the difference between 2010 and 2025
subtract 60k (that is the 15 years multiplied by 4k) from 450k and you get 390k.

Consider the following functions. f1(x) = x, f2(x) = x2, f3(x) = 2x − 4x2 g(x) = c1f1(x) + c2f2(x) + c3f3(x) Solve for c1, c2, a

Answer:

  • (c1, c2, c3) = (-2t, 4t, t) . . . . for any value of t
  • NOT linearly independent

Step-by-step explanation:

We want ...

  c1·f1(x) +c2·f2(x) +c3·f3(x) = g(x) ≡ 0

Substituting for the fn function values, we have ...

  c1·x +c2·x² +c3·(2x -4x²) ≡ 0

This resolves to two equations:

  x(c1 +2c3) = 0

  x²(c2 -4c3) = 0

These have an infinite set of solutions:

  c1 = -2c3

  c2 = 4c3

Then for any parameter t, including the "trivial" t=0, ...

  (c1, c2, c3) = (-2t, 4t, t)

__

f1, f2, f3 are NOT linearly independent. (If they were, there would be only one solution making g(x) ≡ 0.)

matrenka [14]

Answer:

Step-by-step explanation:

When x=3, y = ln(3-2) =  ln(1) = 0.

:::::

When x=4, y = ln(4-2) = ln(2) ≅ 0.693.

:::::

When x=6, y = ln(6-2) = ln(4) ≅ 1.386.
