Isn't it 2/4? Because there are 2 coins and there are 2 tails, and 2 heads, in all that's 4

Dwight creates a table of values for a function and plots the points. He finds that one y value divided by the next y value prod

Mashcka [7]

we know that

The exponential function is of the form

$f(x)=a^{x}$

where

a is any value greater than $0$

In General:

It is always greater than $0$ , and never crosses the x-axis

It always intersects the y-axis at $y=1$

Its Domain is the Real Numbers

Its Range is the Positive Real Numbers

Examples

Let

$a=3$

1) For $x=2$

$f(2)=3^{2} \\ f(2)=9$

2) For $x=3$

$f(3)=3^{3} \\ f(3)=27$

3) For $x=4$

$f(4)=3^{4} \\ f(4)=81$

4) For $x=5$

$f(5)=3^{5} \\ f(5)=243$

$f(3)/f(2)=\frac{27}{9} \\ =3$

$f(4)/f(3)=\frac{81}{27} \\ =3$

$f(5)/f(4)=\frac{243}{81} \\ =3$

therefore

the answer is the option

Which description matches the graph of the inequality y ≥ |x + 2| – 3? a shaded region above a solid boundary line a shaded regi

Alex777 [14]

The given inequality is y ≥ |x + 2| -3.

This inequality may be written two ways:
(a) y ≥ x + 2 - 3
or
y ≥ x - 1

(b) y ≥ -x -2 - 3
or
y ≥ -x - 5

A graph of the inequality is shown below. The shaded region satisfies the inequality.

Answer: A shaded region above a solid boundary line.

The volume of a cone is 108 pi cubic inches. Its height is 4 inches. What is the radius of the cone? Round answer to nearest ten

leonid [27]

$\bf \textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}~~ \begin{cases} r=radius\\ h=height\\ -----\\ V=108\pi \\ h=4 \end{cases}\implies 108\pi =\cfrac{\pi r^2(4)}{3}\implies 324\pi =4\pi r^2 \\\\\\ \cfrac{324\pi }{4\pi }=r^2\implies 81=r^2\implies \sqrt{81}=r\implies 9=r$

$\bold{\huge{\underline{ Solution\: 2 }}}$

The name of the circle is IJKL
The name of central Angle
$\sf{\underline{= {\angle} IHJ }}$
The name of the secant = KL

${\bigstar}$ Circle :- It is a round figures, which has no end points.

${\bigstar}$ Central angle :- It the angle ,which lie in the middle of the circle.

Here, H is the mid point of the circle .So, Angle IHJ is the central angle.

${\bigstar}$ Secant :- A line drawn in circle in such a way that it intersect the circle from two distinct points. Then, It is called secant .

Here, KL is the line which acts as a secant because it intersect the circle from point K and point L.

$\bold{\huge{\underline{ Solution\: 3 }}}$

Semicircle = FGH and FIH
Minor Arc :- FG or GH
Major Arc :- FHG or GFH

${\bigstar}$ Semicircle :- Semicircle is nothing but the half of the circle.

Here, In second diagram 

FGH and FIH are acting as two semicircles which simulatineously forming one circle.

${\bigstar}$ Minor Arc :- Minor Arc is nothing but the smaller arc of the circle and it is always smaller than the half of the circle that is semicircle.

Here, 

FG or GH are the minor arc of the given circle.

${\bigstar}$ Major Arc :- Major Arc is nothing but the largest arc of the circle and it is always larger than the half of the circle that is semicircle.

Here, 

FHG or GFH is the major arc as it is larger than the semicircle of the given circle .
