Answer:

The correct option is D.

Step-by-step explanation:

We have to find the expresses this statement: A quantity x is equal to the sum of the squares of a and b.

The square of a can be written as a² and the square of b can be written as b².

The sum of squares of a and b can be written as

a^2+b^2

Since the quantity x is equal to the sum of the squares of a and b, therefore

x=a^2+b^2

Therefore option D is correct.

Answer:

  • Parent Function:  y=\sqrt{x}
  • Horizontal shift: right 3 units
  • Vertical shift: up 3 units
  • Reflection about the x-axis: none
  • Vertical strech: streched

Step-by-step explanation:

assume that y=\sqrt{x} is f(x)=\sqrt{x} and y=\sqrt{-2x+6}+3 is

g(x)=\sqrt{-2x+6}+3\\ f(x)=\sqrt{x} \\g(x)=\sqrt{-2x+6}+3

The transformation from the first equation to the second equation can be found by finding a,h and k for each equation.

y=a\sqrt{x-h}+k

factor a 1 out of the absolute value to make the coefficient of x equal to 1

y=\sqrt{x}

factor a 2 out of the absolute value to make the coefficient of x equal to 1

y=\sqrt{2}\sqrt{x-3}+3

find a, h and k for y=\sqrt{2}\sqrt{x-3}+3

a=1.41421356\\ h=3\\k=3

the horizontal shift depends on the value of h when h > 0, the horizontal shift is described as:

g(x)=f(x+h) - the graph is shifted to the left h units

g(x)=f(x-h)\\ - the graph is shifted to the right h units

the vertical shift depends on the value of k

Verizon [17]

Answer:

arc FD = 236°

Step-by-step explanation:

The measure of the arc is equal to the measure of the central angle it subtends, thus

arc FD = arc FE + arc ED = 146° + 90° = 236°
