Exact Area = pi square units
Approximate Area = 3.14 square units
=========================================
Work Shown:
The full circle area is pi*r^2 = pi*2^2 = 4pi
This quarter circle has area (4pi)/4 = pi square units
This is approximately equal to pi = 3.14
2+1 is 21 because 2 and 1 make 21 so it’s 21
Your answer should be B, less than 2
With the rate of change known, the equation is most likely:
Y = 7X
So if we were to plug in 12 for Y...
12 = 7X
Divide both by 7
1.714 = X
Which is slightly less than 2.
I hope this helps!
You know we can't draw it, but I will give you all information so that to enable you draw this parabola
y = (x-4)² +3.
1-The coefficient of x =1 so it's positive, the parabola passe by a minimum or opens upward
2- It doesn't intercepts the x-axis since it has no zero value
3- its shifted 3 units upward & shifted 4 units to the right
4- its axis of symmetry is x=4 & its minimum is at (-3 , 3)
Hope this will help
7x^2 - 3x^2 = 4x^2
-2x+4X=4X
5+ 10 = 15
4x^2 + 4x + 15
