Determine the number of diagonal of a dodecagon?

1 answer:

Katen [24]3 years ago

5 0

Use this pattern to predict the number of diagonals in a dodecagon (12-sided polygon). First create a triangle. Since you are looking for diagonals you must go from vertex to vertex, but they cannot be adjacent to each other. Therefore a triangle has no diagonals.

The math club is selling T-shirts to raise money. Each T-shirt sold represents a profit of $2. The club has a total of 500 T-

vova2212 [387]

Answer:

2 < or equal to (t) < or equal to 1000

Step-by-step explanation:

2 is the profit of the (t) amount of t shirts so the amount should be greater than or equal too 1000 because if they have 500 shirts 500 x 2 is 1000

If the graph is reflected across the y-axis, what will be the equation of the new graph?

Bumek [7]

Answer:

$\displaystyle b)y = { 3}^{ - x} + 1$

Step-by-step explanation:

we are given a exponential function

$\displaystyle y = {3}^{x} + 1$

we want to figure out the equation of the new graph reflected across the y-axis

remember that,

$\rm\displaystyle (x,y) \xrightarrow{ \text{ reflection over y - axis}}( - x,y)$

let y be $3^x+1$ so,

$\rm\displaystyle (x,y) \xrightarrow{ \text{ reflection over y - axis}}( - x, {3}^{ - x} + 1 )$

hence,

the equation of the new graph

$\displaystyle y = { 3}^{ - x} + 1$
