Answer:

D. 3x^4 - 10x^2 + 6

Step-by-step explanation:

Let's work our way from the front of the equation to the back.

x^2 x 3x^2

to make this easier we are gonna separate the exponent and deal with that after.

x x 3x

Well that is basically 1 x 3 so that is 3. So we can easily cross out A.

Now we can deal with the exponents. When the equations are multiplying, we are gonna add the exponents.

2 + 2 = 4.

Okay, now let's deal with -5x and 2x

-5x x 2x

Easy, just multiply the numbers while adding the exponents like we did before.

-10x^2

And if you look at the 3 remaining answers

Only D. starts off with 3x^4 -10x^2

So eliminating the rest, now you are left it D as the answer

barxatty [35]

Answer:

48,558

Step-by-step explanation:

The function which models the relationship between the elapsed time, t in years, since 2010 and the town's population, P(t), is given as:

$P(t)=36800\cdot2^{^\dfrac{t}{25}}$

Now, 2020-2010=10 Years

Therefore we are required to calculate the population of the town 10 years after.

To do this, we simply substitute t=10 in the function.

$P(10)=36800\cdot2^{^\dfrac{10}{25}}}\\=48557.9\\\approx 48558$

According to the model, the population in Fall River will be 48,558 in the Year 2020.

Twice the sum of a number and 3 is equal to three times the difference of the number and 3

lana66690 [7]

Twice the sum of a number and 3 = 2(n + 3)
three times the difference of the number and 3 = 3(n - 3)
so
Twice the sum of a number and 3 is equal to three times the difference of the number and 3:
2(n + 3) = 3(n - 3)
2n + 6 = 3n - 9
n = 15

answer
2(n + 3) = 3(n - 3)
n = 15

I need help is it A B C Or D

Anarel [89]

Natural selection is the process where organisms are more likely to reproduce. When they reproduce, they pass on traits to the next generation. Over time this process allows organisms to adapt to their environment. Giving what natural selection means, I believe the answer is D. Evolution does NOT always improve organisms.

I hope this helps:)
