Answer:

Step-by-step explanation:

h(a) = 2a+ 5

g(a) = 3a−5

h(a)+g(a)

(2a+5)+(3a-5) (substitution)

2a+5+3a-5 (open parentheses)

5a+0 (solve)

Given that the quadratic equation has equal roots (k^2-1)x^2-2kx-3k-1=0

Alik [6]

Answer:

(See explanation for further details)

Step-by-step explanation:

The real expression is:

$(k^{2}-1)\cdot x{{2} - 2\cdot k \cdot x - 3\cdot k + 1 = 0$

The general equation for the second-order polynomial is:

$x = \frac{2\cdot k \pm \sqrt{4\cdot k^{2}-4\cdot (k^{2}-1)\cdot (-3\cdot k + 1)}}{k^{2}-1}$

This condition must be observed for the case of a quadratic equation with equal roots:

$4\cdot k^{2} - 4\cdot (k^{2}-1)\cdot (-3\cdot k + 1) = 0$

$k^{2} + (k^{2}-1)\cdot (3\cdot k + 1) = 0$

$k^{2} + 3\cdot k^{3} - 3\cdot k - k^{2}-1 = 0$

$3\cdot k^{3} - 3\cdot k - 1 = 0$

In 2012, the population of a city was 6.29 million. The exponential growth rate was

RoseWind [281]

Answer:

a) P(t) = 6.29e^(0.0241t)

b) P(6) ≈ 7.3 million

c) 10 years

d) 28.8 years

Step-by-step explanation:

a) You have written the equation.

P(t) = 6.29·e^(0.0241·t)

b) 2018 is 6 years after 2012.

P(6) = 6.29·e^(0.0241·6) ≈ 7.2686 ≈ 7.3 . . . million

c) We want t for ...

8 = 6.29·e^(0.0241t)

ln(8/6.29) = 0.0241t

t = ln(8/6.29)/0.0241 ≈ 9.978 ≈ 10.0 . . . years

d) Along the same lines as the calculation in part (c), doubling time is ...

t = ln(2)/0.0241 ≈ 28.7613 ≈ 28.8 . . . years
