Answer:

Step-by-step explanation:
Given:
x>0
Which means
x is any number greater than 0 ig 1,2,3,4,5,7,9.......
y<0
Which means
y Is any number smaller than 0
ig -1,-2,-3,-4,-5.........
So according to the question
The coordinates are
(x,-y)
Therefore,
The points are located to Quadrant IV
Answer:

Step-by-step explanation:
we would like to solve the following equation:

in order to do so do cross multiplication:

divide both sides by √3:

since we ended up with a square root on the denominator so we can consider rationalising the denominator to do so multiply both numerator and denominator by √3 which yields:

simplify multiplication:

reduce fraction:

and we are done!
6 times 1 =6
2 times x =6
x=3
X^1/2 - x
-2x^3 - x^1/2 - x
-2x^3 - 2x
i think this is it
Answer:
Ans: -21.87 ≅ -22°C
Step-by-step explanation:
T(x)=-22+44e^-0.03x
Initial temperature (x = 0):
T(0) = = -22 + 44e-0.03(0) = -22 + 44(1) = 22°C
After 18 minutes (x = 18):
T(18) = -22 + 44e-0.03(18) = -21.87°C ≅ -22°C
