Answer:
Step-by-step explanation:
The given equation is
For this function to have an inverse, we must restrict the domain, say
We interchange x and y to get,
We now make y the subject to get;
We divide through by 16 to get;
We now take the square root of both sides to get;
Since , the inverse function is
If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down (no change).
Well...it says the sum of the angles measure 360...so lets set them equal to 360
40 + x - 10 + 1/3x + x - 20 = 360...combine like terms
2 1/3x + 10 = 360
7/3x = 360 - 10
7/3x = 350
x = 350/(7/3)
x = 350 * 3/7
x = 1050/7
x = 150 <=====
Step-by-step explanation:
1. solution,
length of rectangle A(l)=3.1units
breadth of rectangle A(b)=1units
now,
area of rectangle A=l×b
=3.1units×1units
=3.1 sq units
2.solution,
length of rectangle B(l)=3.1units
breadth of rectangle B (b)=0.4units
now,
area of rectangleB=l×b
=3.1units×0.4units
=1.24 sq units
3.solution,
length=3.1units
breadth=1.4units
area =lxb
=3.1units x 1.4units
=4.34units
