Does anybody know the answer?

What are the zeros of the graphed function y = 1/3 (x + 3)(x + 5)?

Darya [45]

One factor will be zero, hence y will be zero, when x=-3.

The other factor will be zero, hence y will be zero, when x=-5.

The zeros of the function are x ∈ {-5, -3}.

_____

This solution makes use of the "zero product rule," which states a product is zero if and only if one or more factors is zero.

The question is incomplete. Below you will find the missing figure.

Two friends, Andrew and Liz, are playing a game using this spinner. If the

spinner lands on region 2 or 3, Andrew wins. If it lands on region 4, Liz wins. If it lands on any other region, neither wins. Is this a fair game?

A. Yes. Each friend has a 1/4 probability of winning.

B. Yes. Each friend has a 1/6 probability of winning.

C. No. Andrew has a probability of 1/4 winning and Liz has a probability of 1/6 winning.

D. No. Andrew has a probability of 1/3 winning and Liz has a probability of 1/4 winning.

The correct option is Option A: Yes. Each friend has 1/4 probability of winning.

Probability is the possibility of an event to happen which is the ratio of no. favorable outcomes and no. of total outcomes.

P = no. of favorable outcome/ total no. of outcome

Here given in the question,

If the spinner touches region 2 or 3, Andrew wins

If the spinner touches region 4, Liz wins.

This is fair play because both have the same size of region for winning.

If we cut the circle into 8 pieces,

as region 1 is the sum of 2 sub-parts of the circle,

possibility of spinner touching region 1= 2/8= 1/4

possibility of spinner touching the small region = 1/8

So the possibility of the spinner touching the region 2or 3= 1/8+1/8= 2/8= 1/4

Hence the possibility of Andrew wins= possibility of the spinner touching region 1= 1/4

possibility of Liz wins= possibility of the spinner touching the region 2 or 3= 1/4

Therefore the correct option is Option A: Yes. Each friend has 1/4 probability of winning.

What is 20% of $36<br> PLEASE HELP ME

Amanda [17]

Answer:

$7.20

Step-by-step explanation:

20% is the same as 0.2 or 2/10, which simplifies to 1/5.

1/5*36=36/5=7.20

Or you could straight up to 20%*36=7.20

using the midpoint formula find the coordinates of the midpoint 9f each sigment with end points (4,2),(-5,-1)

exis [7]

Answer:

The midpoint of the segment is (-0.5,0.5).

Step-by-step explanation:

Midpoint of a segment:

The midpoint of a segment is given by the mean of its coordinates.

Segment with end points (4,2),(-5,-1)

x-coordinates: 4 and -5

y-coordinates: 2 and -1

x-coordinate of the midpoint:

$x = \frac{4-5}{2} = -\frac{1}{2} = -0.5$

y-coordinate of the midpoint:

$y = \frac{2-1}{2} = \frac{1}{2} = 0.5$

The midpoint of the segment is (-0.5,0.5).

Joey is buying plants for his garden. He wants to have at least twice as many flowering plants as nonflowering plants and a mini

vodomira [7]

(24, 12) and (36, 0). The least amount of flowering plants occurs when x=2y, and the largest amount occurs when y=0. These two points satisfy both conditions and both sum to 36.
