Answer:

AY = 16

IY = 9

FG = 30

PA = 24

Step-by-step explanation:

<em>The </em><em>centroid </em><em>of the triangle </em><em>divides each median</em><em> at the ratio </em><em>1: 2</em><em> from </em><em>the base</em>

Let us solve the problem

In Δ AFT

∵ Y is the centroid

∵ AP, TI, and FG are medians

→ By using the rule above

∴ Y divides AP at ratio 1: 2 from the base FT

∴ AY = 2 YP

∵ YP = 8

∴ AY = 2(8)

∴ AY = 16

∵ PA = AY + YP

∴ AP = 16 + 8

∴ AP = 24

∵ Y divides TI at ratio 1: 2 from the base FA

∴ TY = 2 IY

∵ TY = 18

∴ 18 = 2

→ Divide both sides by 2

∴ 9 = IY

∴ IY = 9

∵ Y divides FG at ratio 1:2 from the base AT

∴ FY = 2 YG

∵ FY = 20

∴ 20 = 2 YG

→ Divide both sides by 2

∴ 10 = YG

∴ YG = 10

∵ FG = YG + FY

∴ FG = 10 + 20

∴ FG = 30

PART A:
x | 0  |  1  |  2 | 3  | 4   | 5  |  6  |  7  | 8  | 9 | 10 | 11 | 12 |
y | 6 | 5.5 | 5 | 4.5 | 4 | 3.5 | 3 | 2.5 | 2 | 1.5 | 1 | 0.5 | 0 |

x=hours
y=candle length

PART B:
Yes it is a function because you can input the values 

PART C: 
Yes, it will still be a function but with a different different y value

bogdanovich [222]

Answer:

Step-by-step explanation:

Given that you have been discussing a research project with your friend Connor. Connor has told you that his research hypothesis states, the mean of population 1 is not equal to the mean of population 2.

So our null hypothesis should be

H_0: \mu_1 =\mu_2\\H_a: \mu_1 \neq \mu_2

This is a two tailed test

How we write in symbols is shown in Ha as above.

not equal to sign is used here to represent.

Mr.Brown deposited $2500 to his new savings account. Each month, he deposits $300 to his account. Which inequality can be used t
Firlakuza [10]

Answer:

X>5

Step-by-step explanation:

Since the initial deposit is given as $2500 then to get more than $4000, Mr. Brown needs additional 4000-2500=$1500

Since each month he deposits $300 then after x months he will have more than $1500 additional.

4000<300x+2500

Collecting like terms

4000-2500<300x

1500<300x

Simplifying

5<x

Or

x>5
