Answer:

B 12.68

Step-by-step explanation:

you will need to find the distance between each segment-

so the length of DC, CF, FE, ED

d=\sqrt{(x_{2}-x_{1})  ^{2}+(y_{2}-y_{1})  ^{2}  }

DC:

D(-2,-1) C(-1,2)

d=\sqrt{(-1--2)^{2} +(2--1)^{2} } \\d=\sqrt{1^{2}+3^{2}  } \\d=\sqrt{10} =3.16

CF:

C(-1,2) F(1,1)

d=\sqrt{(1--1)^{2} +(1-2)^{2} } \\d=\sqrt{2^{2}+-1^{2}  } \\d=\sqrt{4+1} \\d=\sqrt{x} 5=2.24

FE

F(1,1) E(2,-2)

d=\sqrt{(2-1)^{2} +(-2-1)^{2} } \\d=\sqrt{1^{2} +(-3)^{2} } \\d=\sqrt{1+9} \\d=\sqrt{10}= 3.16

ED

E(2,-2) D(-2,-1)

d=\sqrt{(-2-2)^{2} +(-1--2)^{2} } \\d=\sqrt{(-4)^{2}+1^{2}  } \\d=\sqrt{16+1} \\d=\sqrt{17}= 4.12\\

3.16+2.24+3.16+4.12= 12.68

The graph of F(X), shown below, has the same shape as the graph of
marshall27 [118]

Answer:

The correct option is;

D. F(x) = x⁴ - x² + 2

Step-by-step explanation:

From the graph, we have;

The y-intercept =  2, therefore, when x = 0, y = 2

The graph has no x-intercept, therefore, the unction has complex roots

The possible function is F(x) = x⁴ + x² + 2 and F(x) = 2 - x⁴ - x²

The roots of the function, F(x) = x⁴ - x² + 2, is given as follows;

0 = x⁴ - x² + 2

x = (1 ± √(1 - 8))/(2) = (1 ± √(-7))/(2) which are imaginary roots

For F(x) = 2 - x⁴ - x², we have;

0 = 2 - x⁴ - x²

x = (1 ± √(1 + 8))/(2) = (1 ± 3)/(2)

x = 2 or x = -1, therefore, the function, F(x) = 2 - x⁴ - x², has real roots and the only possible solution is F(x) = x⁴ + x² + 2

What is the notation for an inverse function?
solniwko [45]

Answer:

Notation. The inverse of the function f is denoted by f -1 (if your browser doesn't support superscripts, that is looks like f with an exponent of -1) and is pronounced "f inverse". Although the inverse of a function looks like you're raising the function to the -1 power, it isn't.

Nimfa-mama [501]

Answer:

If you assume a six sided die there are 3 odd numbers, 1,3, 5. And 6 total sides, so 3/6 = 1/2 or 50%.
