The diameter of a pizza is 14 inches. The pizza has 8 slices of equal size. Which of the following is the closest to the area of

qwelly [4]

Answer:

Step-by-step explanation:

First let us find the area of the whole pizza. Area of a circle is:

$A=\pi r^2$

Then, we have diameter as:

$diameter\div2=radius$

So, then using these formulas we would have,

$16\div2=8\\A=8\pi \text{ or }25.12$

Now, one slice is $\frac{1}{8}$ of the entire pizza. So, we would have:

$8\pi\div8=1\pi\\\text{ or }\\25.12\div8=3.14$

Quadrilateral FRIO is the result of a reflection of quadrilateral LAMB over the y-axis. FRIO has vertices at F(-7,6), R(1,7), I(

andrew11 [14]

Answer:

F' = (7, 6)

R' = (-1, 7)

I' = (-2, -5)

O' = (6, -6)

Step-by-step explanation:

The rule of reflection over the y-axis is, (x, y) ---> (-x, y). So change all the x values into the opposite signs. So the -7 of F would turn into just 7, the 1 of R would turn into -1, the 2 of I would turn into -2, and -6 of O would turn into just 6.

Could I solve this inequality by completing the square? How would I do so?

sammy [17]

Answer:

$\large\boxed{x>-2+\sqrt{14}\ \vee\ x$

Step-by-step explanation:

$x^2+4x>10\\\\x^2+2(x)(2)>10\qquad\text{add}\ 2^2=4\ \text{to both sides}\\\\x^2+2(x)(2)+2^2>10+4\qquad\text{use}\ (a+b)^2=a^2+2ab+b^2\\\\(x+2)^2>14\Rightarrow x+2>\sqrt{14}\ \vee\ x+2-2+\sqrt{14}\ \vee\ x$
