Hello : 
q(r)=3<span>√(r²-16)
q  exist : r² - 16 </span><span>≥ 0
r² </span><span>≥ 16
</span>√r² ≥ √16
but :  √16 = 4    and  √r² = <span>|r |
</span>|r | ≥ 4
r ≤ 4 or  r  ≥ 4 
the domain is :  ] -∞, 4] ∪  [,4 , + ∞ [

Please answer all i need help Factor the expression using the GCF. 50x-60 Next one Factor the expression using the GCF. 16m+40 n
Anton [14]

Answer:

10(5x - 6).

8(2m + 5).

9(3 - 5c)

Step-by-step explanation:

Given that

50x-60

16m+40

27-45c

The greatest common factor is a measure of the highest number present inside, or common to all the numbers that were listed. To take this one at a time, we have....

50x - 60. The highest number common to both of them is 10, and thus, we have

50x - 60 = 10(5x - 6), and this is the solved part.

16m + 40. The greatest number that's present inside both numbers is 8, and thus we have

16m + 40 = 8(2m + 5) and this is the solved part.

27 - 45c. The greatest common number is 9, and as a result, we have

27 - 45c = 9(3 - 5c), and this is the solution we were searching for

If sin θ = 3/5 find the value of 4 tanθ + 3 sinθ – 6 cosθ
zepelin [54]

Step-by-step explanation:

If sine theta is 3/5, taking the sine inverse will give you 36.87°.

4tan theta is 4 × tan36.87 = 3

3sin theta = 3 × sin36.87 = 1.8

6cos theta is 6× cos36.87 = 4.8

Therefore, it becomes 3 + 1.8 - 4.8 = 4.8 - 4.8

The answer is 0
