To check 65-32=34 you have to add because the inverse operation of subtraction is addition so add 34+32=56
so the answer is wrong
To check the second problem u have to subtract and then do the same as the first question

(cos Ф -cos Ф)² + (cos Ф + cos Ф)²

Firstly: (cos Ф -cos Ф)² = 0² = 0

Secondly :(cos Ф + cos Ф)² = (2cos Ф)². = 4. (cos Ф)² = 4cos² Ф

Mind you when you raise a cosine (or sin or tan...) to the n power, the n power should affect the cosine only and NOT the angle Ф

A skateboard travels 55 feet in 4 seconds. Is the skateboard going faster, slower, or the same speed as the scooter?
Assoli18 [71]

Answer:

Slower.

Step-by-step explanation:

I belive it is slower because the scooter was 30 feet per 2 seconds. 30+30+60 feet, 2+2= 4 seconds= 60 feet and 4 seconds which makes the 55 feet per 4 seconds slower.

When finding the median, do we have to put the numbers in order from least to greatest
iris [78.8K]
Yes you do. Place all of the numbers, even repeating ones, in order from slammers to largest and then start crossing out from both sides until you get the middle. For example, in the problem below the median would be 4 bc it’s in the middle
