Mathematics

Answer:

729 and -2187 are the next on the list

<em></em>

Step-by-step explanation:

Given

9,-27,81, -243,.. ​

Required

Determine the next two numbers

The first step is to determine the formula that guides the pattern

Start by expressing all elements in the pattern as a base of -3

This gives:

(-3)^2; (-3)^3; (-3)^4; (-3)^5;

Check if it corresponds with the given pattern

(-3)^2 = 9        (-3)^3 = -27     (-3)^4 = 81      (-3)^5 = -243

Let the above expression reflect their position in the pattern

(-3)^{1 + 1}; (-3)^{2 + 1}; (-3)^{3 + 1}; (-3)^{4 + 1};

By comparing each element;

We have that

T_n = (-3)^{n+1}

The next two numbers is when n = 5 and n = 6

When n = 5

T_5 = (-3)^{5+1}

T_5 = (-3)^6

T_5 = 729

When n = 6

T_6 = (-3)^{6+1}

T_6 = (-3)^7

T_6 = -2187

Hence;

<em>729 and -2187 are the next on the list</em>

Answer:The difference between the medians is 2.5

Step-by-step explanation: So how I did this is first I found the median of the two plots (median=the middle number in a group of values) so anyway I lined it all out because I find it easier to do it that way (20,25,25,30,30,30,30) so the answers I got for both plots were -plot A=32.5 and plot B=30 than difference means subtract so 32.5-30=2.5

Find FL if H is the circumcenter of EFG,
Zanzabum

The artistic crop isn't helpful; it cuts off some vertex names.

The circumcenter H is the meet of the perpendicular bisectors of the sides, helpfully drawn.  We have right triangle ELH, right angle L, so

EH² = HL² + EL²

EL = √(EH² - HL²) = √(5.06²-2.74²) ≈ 4.2539393507665339

Since HL is a perpendicular bisector of EF, we get congruent segments FL=EL.

Answer: 4.25
