If the diameter of a semi circle is 2 inches what is the semi circles perimeter

SpyIntel [72]

Answer: 5.14 cu in

Step-by-step explanation:

1/2 (π × d) + d, where d is the diameter of the semi

Perimeter = 1/2 (3.14 x 2) + 2

= 1/2 * 6.28 + 2

= 3.14 + 2

Solve for g: C = 1/2gk

sweet-ann [11.9K]

Answer:

G = $\frac{C(2)}{k}$

Step-by-step explanation:

C = 1/2gk

First you want to multiple both sides by 2 to get rid of that fraction and you get

C (2) = gk then you divide both sides by k to isolate the g and your left with

G= $\frac{C(2)}{k}$

Hope this helps

If f(x) = x^2-1 which of the following ordered pairs would be on the graph of f(x)

Alex Ar [27]

These following ordered pairs are on the graph:

(0,1)
(5, 24)
(-2,3)

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

An ordered pair (x, f(x)) will be on the graph if replacing them into the equation, we get an equivalence.

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

The equation is:

$f(x) = x^2 - 1$

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

(0,1)

Here, we test $x = 0, f(x) = 1$

Replacing into the equation:

$1 = 0^2 - 1$

$1 = -1$

False, so not on the graph.

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

(0,1)

Here, we test $x = 1, f(x) = 0$

Replacing into the equation:

$0 = 1^2 - 1$

$0 = 0$

True, so on the graph.

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

(3,5)

Here, we test $x = 3, f(x) = 5$

Replacing into the equation:

$5 = 3^2 - 1$

$5 = 8$

False, so not on the graph.

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

(5,24)

Here, we test $x = 5, f(x) = 24$

Replacing into the equation:

$24 = 5^2 - 1$

$24 = 24$

True, so on the graph.

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

(-2,3)

Here, we test $x = -2, f(x) = 3$

Replacing into the equation:

$3 = (-2)^2 - 1$

$3 = 3$

True, so on the graph.

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

(-4,-17)

Here, we test $x = -4, f(x) = -17$

Replacing into the equation:

$-17 = (-4)^2 - 1$

$-17 = 15$

False, so not on the graph.
