An exponential function is a function in which the independent variable is an exponent. Exponential functions have the general form y = f (x) = ax, where a > 0, a≠1, and x is any real number. The reason a > 0 is that if it is negative, the function is undefined for -1 < x < 1.
Answer:
1,650.1184
Step-by-step explanation:
If the circumference is 144.4 then you would divide the circumference by pi which would get you the diameter. Divide the diameter by 2 which would be the radius. Square the radius the multiply pi to get the area.
Answer:
first calculate the area of the arch using:
O/360×πr2
O represents theta
second calculate the area of the circle using πr2
finally minus the answer gotten from the two different areas
thats how u get the area of the shaded area
Answer:
13cm
Step-by-step explanation:
Let the length of each side be x;
Using the pythagoras theorem
l² = x² + x²
l is the length of the diagonal
l² = 2x²
19² = 2x²
361 = 2x²
x² = 361/2
x² = 180.5
x =√180.5
x = 13
hence the length of each side of the square is closest to 13cm
They are similar because they both are triangles. But they are not the same size.
