If f(x)=3^x+10× and g(x)=2x-4, find (f-g)(x)

1 answer:

8 0

The problem is asking for the difference between the formulas for the functions f and g (in that order). So you subtract g from f.

$(f-g)(x)=f(x)-g(x) =(3^x + 10x) - (2x - 4) \\ = 3^x+10x-2x+4$

The following three shapes are based only on squares, semicircles, and quarter circles. Find the perimeter and the area of each

MakcuM [25]

The perimeter = 4 * length of a semicircle of radius 5 == 4* pi * 5 = 20 pi cm

The area of one of the clear parts = 1/2 area of square - area semicircle

= 1/2 * 10^2 - 1/2 pi *5^2 = 50 - 12.5pi

So area of shaded parts = area of square - 4 (50 - 12.5pi)
= 100 - 200 + 100pi = (100pi - 100) cm^2
