The domain of the function:y = 3 √ ( 6 x + 42 )6 x + 42 ≥ 06 x ≥ - 42x ≥ - 42 : 6x ≥ - 7Answer:The domain is D ) x ≥ - 7
In the first quadrant, tangent, sine and cosine function are all positive.
So tan(90-A) = sin(90-A) / cos(90-A) = cos(A) / sin(A) = 1/tan(A)
Answer is d
By just taking a glimpse at the problem, you can immediately mentally determine whether 125 x 0.9 is greater than 125. You are multiplying 125 by a positive number that is greater than 1, therefore the value will increase. This is how anyone can mentally envision 125 x 0.9 to be greater than 125.
Answer:
9.5%
Step-by-step explanation:
To find out the percentage, you do (3.99/42) * 100.
1.80 divided by 7 would give you .257 but if you round it, it's.26
