Solve the equation: k^2+5k+13=0

Step-by-step explanation:

k² + 5k + 13 = 0

Using the quadratic formula which is

From the question

a = 1 , b = 5 , c = 13

So we have

Separate the solutions

The equation has complex roots

Separate the real and imaginary parts

We have the final answer as

Hope this helps you

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
