Answer:

D. Polar.

Step-by-step explanation:

We are asked to choose the two most commonly used systems of coordinates.

We know that most commonly used systems of coordinates are the rectangular coordinate system and the polar coordinate system.

The rectangular coordinate system is also known as Cartesian coordinate system.

Therefore, option D is the correct choice.

PLEASE HELP!!! WILL MARK AS BRAINLIEST!!!

Answer:

$y = 300 (2)^x$

Where x represent the number of period of times of 22 minutes. If we want to know the value of the population after 66 minutes we need to find the value of x on this way:

$x = 66 minutes *\frac{1period}{22 minutes}= 3$

So then we need to replace the value of x =3 and we got:

$y= 300 (2)^3 = 2400$

Step-by-step explanation:

For this case we have the following function:

$y = 300 (2)^x$

Where x represent the number of period of times of 22 minutes. If we want to know the value of the population after 66 minutes we need to find the value of x on this way:

$x = 66 minutes *\frac{1period}{22 minutes}= 3$

So then we need to replace the value of x =3 and we got:

$y= 300 (2)^3 = 2400$

Factor by Grouping.

Komok [63]

Answer:

The ac product of $35x^2+41x+12$ is 420.

The factors of the ac product that add to 41 are 20 and 21.

$35x^2+41x+12 =$ $(7x+4)(5x+3)$

Step-by-step explanation:

1) The general form of a quadratic is $ax^2 + bx + c$ . Hence, multiplying 35 by 12 gives you the product of ac, which is 420.

2) We need to find two numbers that multiply to 420 and add up to 41 simultaneously. If we pull out the factors of 420, two of them will be 20 and 21, which multiply to 420 as well as add up to 41.

3) Write $41x$ as a sum.
