Answer from: WhitneyNH4261

1.A

2.D.

3.D

4.D

Step-by-step explanation:

1.We are given that an angle

We have to find the name of given angle.

G is the vertices of given angle.

We know that vertices is always write in mid of the name of an angle

Suppose an angle ABC with vertices B.

There is B is in the middle of given name ABC.

Therefore, the correct name of given angle is Angle DGH.

Hence, option A is true.

2.We are given that CH=6

We have to find that statement for which is CH=6

We are given that SH=CM=4

HT=6

ST=4+6=10

CH=6

MH=MC+CH=4+6=10

Hence, MH=ST

Therefore, option D is true.

3.We are given that line DF and EG

We have to find the intersection of DF and EG

DF=DE+EF

EG=EF+FG

EF is common in both lines .Therefore, EF is the intersection of line DF and EG.

Hence, option D is true.

4.We are given that BD and CB

We have to find the intersection of BD and line BC

BD=BC+CD

BC is common in both therefore,BC is the intersection of both BD and line CB.

Hence, option D is true.

Answer from: Quest

i used to know but i learned it a long time ago sorry

step-by-step explanation:

Answer from: Quest

$a_1 = 1$ , and

$a_{n+1} = a_n + (n + 1)$ for $n \ge 1$

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote $a_1 = 1$ , $a_2 = 3$ , $a_3 = 6$ , so that we can call

1 the 1st term, 3 the 2nd term, 6 the 3rd term,etc.

note the following:

from the 1st term (1) to the 2nd term (3), we go up by 2,from the 2nd term (3) to the 3rd term (6), we go up by 3from the 3rd term (6) to the 4th term (10), we go up by 4, andfrom the 4th term (10) to the 5th term (15), we go up by 5.

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from $a_1 = 1$ , to get to $a_2 = 3$ , we add $2(=1+1)$

from $a_2 = 3$ , to get to $a_3 = 6$ , we add $3 (=2+1)$

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

$a_1 = 1$ , and $a_{n+1} = a_n +(n + 1)$ for $n \ge 1$
