It’s convex hexagon
Gnom [1K]3 years ago
3 0
Hi there!

First, let's count the sides. There are 6 sides, which means the figure is a hexagon. Concave means that is creates a cave and lines are over each other. Convex means that it looks "normal," so to speak. I've attached an image showing both below. Anyway, this figure would be convex. Therefore the answer is a convex hexagon, answer choice 4.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Factor the following using greatest common factor 6x^2y^3 - 3x^5yz +15x^2y^2
Georgia [21]

Answer:

-3 x^2 y (x^3 z - 2 y^2 - 5 y)

Step-by-step explanation:

6(x^2)(y^3)

3(x^5)(y)(z)

15(x^2)(y^2)

take the least power:

x : 2

y : 1

z : 0

6,3,15: 3

Greatest common factor:

3(x^2)(y)

Factorize:

-3 x^2 y (x^3 z - 2 y^2 - 5 y)

Andy is always looking for ways to make money fast. Lately, he has been trying to make money by gambling. Here is the game he is
Lorico [155]

Answer:

Option B.

Step-by-step explanation:

Cost of game = $5.00

If they draw a face card, they win $10.00 (i.e. they get their $5.00 back and get an extra $5.00).

Winning amount = $5

Number of face cards = 12

Probability of getting a face card =

If they draw an ace, they win $20.00 (i.e. they get their $5.00 back and get an extra $15.00).

Winning amount = $15

Number of ace = 4

Probability of getting an ace  =

Any other draw they lose their money.

Number of other card (Exclude ace and face cards) = 52-4-12=36

Probability of getting other cards  =

The expected money value playing this game is

E(x) = 5 × P(face cards) + 15 × P(Ace) - 5 × P(Other cards)

The expected money value playing this game is -$1.15

Therefore, the correct option is B.

I'm trying to evaluate and solve this quadratic function and I get so lost on word problems I will include a picture
SashulF [63]

Given:

The Revenue function R(x):

R(x)\text{ = 550x}

The cost function C(x) :

C(x)=1240+2x^2

Solution

1. Profit is the difference between the revenue and the cost. Hence, the Profit function P(x) is:

\begin{gathered} P(x)\text{ = R(x) - C(x)} \\ =550x-(1240+2x^2) \\ =550x-1240-2x^2 \end{gathered}

2. The vertical intercept of P(x) can be obtained by substituting x =0 into P(x)

\begin{gathered} P(x)=550x-1240-2x^2 \\ P(0)\text{ = 0 -1240 -0} \\ P(0)\text{ = -1240} \end{gathered}

Ordered Pair : (0, -1240)

If the company sells no items, they would lose $ 1240
