STALIN [3.7K]4 years ago

Okay, so as you know, the question starts off as this:

9x^3 + 2x^2 -5x +4 -(5x^3 -7x +4)
Distribute the negative:
9x^3 + 2x^2 -5x +4 -5x^3 +7x -4
Combine like terms:
9x^3 -5x^3 +2x^2 -5x +7x +4 -4
4x^3 +2x^2 +2x

You can either end it there or
Divide by x:
4x^2 +2x +2

Someone please help i think im just over looking it
Nina [5.8K]
Answer: sen = -15; cos= 8

cot is the cotangent which is calculated by dividing cos by sen. So the dominator(15) is sen and the other number is the cos.
Notice that the number is negative which means one of them (sen or cos) is negative. We know that the angule is in the forth quadrant, and that tells us that, in that quadrant, x is a positive number while y is negative.
X is the cos function and Y is the sen. So, if y is negative, so is sen.

Jada ran 15.25 kilometers. Han ran 8,500 meters. Who ran farther?
Thepotemich [5.8K]

Answer:

Jada

Step-by-step explanation:

We are given Jada's distance in kilometers and Han's distance in meters. To compare the two we need to have them both in the same unit of measurement.

One kilometer is equal to 1000 meters, so Jada ran 15.25*1000=15250 meters.

Compared to Han, who ran 8500 meters, Jada ran farther. 15250>8500.
