You would find the area of the semi circle by using the circle formula and dividing by 2, which would be 8

Solve the following quadratic equation for all values of x in simplest form. 7+2x^2=11​
ollegr [7]

Answer:

x=-\sqrt2\text{ or } x=\sqrt2

Step-by-step explanation:

We have:

7+2x^2=11

To solve, we will isolate the x variable. Therefore, subtract 7 from both sides:

2x^2=4\\

Divide both sides by 2:

x^2=2

Take the square root of both sides. Since we’re taking an event root, we will need plus/minus. Therefore:

x=\pm\sqrt2

Therefore, our solutions are:

x=-\sqrt2\text{ or } x=\sqrt2

Given the equation, what is the center and radius of the circle? <br> (X-2) ^2+ (Y+11)^2=100
LekaFEV [45]

Answer:

Center: (2, -11)

Radius: 10

Step-by-step explanation:

(x - 2)² + (y + 11)² = 100

(x - h)² + (y - k)² = r²

-------------------------------

x - 2 = 0

  +2   +2

x = 2

------------

y + 11 = 0

   -11    -11

y = -11

------------------------------

r² = 100

r = √100

r = 10

----------------------------

Center: (h, k)

Radius: r

-------------------------------

Center: (2, -11)

Radius: 10

I hope this helps!

What values do x and y have if |x| = 16, |y| = 16, and when x and y are combined they equal 0?
True [87]

If x = 16 and y = -16, then x+y = 16+(-16) = 0

Alternatively, if x = -16 and y = 16, then x+y = -16+16 = 0

So y = -x and x can be equal to either 16 or -16
