Answer:

Step-by-step explanation:

statement   Reason

in ΔAOB and ΔCOD

BO=DO       (∵AC bisects BD)

AO=CO       (∵BD bisects AC)

∠AOB=∠COD (Vertically opposite angles)

ΔAOB≡ΔCOD (SAS )

∴∠A=∠C

Answer:

i havent done proofs in a while so i hope this makes sense? you should read over it and edit it if necessary.

i'm pretty sure it's supposed to be congruent triangles

1) AC bisects BD at O - given

2) AO=OC, DO=OB - def. of bisector (you can write these two seperately for both sides but don't think that's needed)

3) <AOB=<DOC - vertical angles

4) triangle AOB is congruent to triangle COD - SAS

5) <A is congruent to <C - CPCTC (corresponding parts of congruent triangles are congruent)

Kryger [21]

Answer:

The answer is below

Step-by-step explanation:

The equation of a linear function is given as:

y = mx + b;

where y, x are variables, m is the rate of change and b is the initial value of variable y.

A) Since there is B bacteria in the Petri dish at 12:00 midnight and the number of bacteria increases after midnight by 25 every hour. Let h represent the time in hours and T represent the total number of bacteria, therefore the equation is:

T = 25h + B

B) Given that B = 5, h = 6, hence:

T = 25(6) + 5 = 150 + 5 = 155 bacteria

C) The equation of the graph is:

T = 25h + 5

The graph was plotted using geogebra online graphing.

Which function has an asymptote at x= 39
LekaFEV [45]

Answer:

option B : f(x)= log_7(x-39)

Step-by-step explanation:

(a) f(x) = 7^{x-39}

For exponential function , there is no vertical asymptotes

General form of exponential function is

f(x) = n^{ax-b}+k

f(x) = 7^{x-39}

In the given f(x) the value of k =0

So horizontal asymptote is y=0

(b) lets check with option

f(x)= log_7(x-39)

To find vertical asymptote we set the argument of log =0  and solve for x

Argument of log is x-39

x-39=0 so x=39

Hence vertical asymptote at x=39

M (Mean) = 20,500;
SD (Standard Deviation) = 55
1 ) 20,555 = 20,500 + 55 = M + 1 SD
Answer: 50% + 34.1% = 84.1%
2 ) 20.610 = 20,000 + 110 = M + 2 SD
Answer: 10% - ( 50% + 34.1% + 13.6% ) = 100% - 97.7% = 2.3% 
3 ) 20,445 = 20,500 - 55 = M - 1 SD
Answer: 50% - 34.1% = 15.9%
