PLEASE HELP I HAVE BEEN TRYING TO FIGURE THIS OUT FOR 4 HOURS AND 15 MINUTES

harkovskaia [24]

Answer:

1. C) 3

2. D) -1

3. D) 7^2 - 8*2 - 16

4. B) 75

5. B) 6^2 + (2 - 8)*sqrt(81)

Step-by-step explanation:

1. (10 - (6-4)^2)/2

= (10 - 2^2)/2

= (10 - 4)/2

= 6/2

= 3

2. PEMDAS states that Multiplication is before Subtraction

8 - (5^2-7)/2

= 8 - (25-7)/2

= 8 - 18/2

= 8 - 9

= -1

3. D) 7^2 - (8*2) - 16

= 49 - 16 - 16

= 49 - 32

= 17

4. 3(2 + 3)^2

= 3(5)^2

= 3(25)

= 75

5. 6^2 + (2 - 8)*sqrt(81)

= 36 + (-6*9)

= 36 - 54

= -18

Point A is located at (−1,−5). The midpoint of line segment AB is point C(2,3). What are the coordinates of point B ?

tamaranim1 [39]

For a segment AB, the coordinates of the middle point C are:

xc=(xa+xb)/2,

yc=(ya+yb)/2.

Now, you know points A and C. Thus we get:

xb=2×xc-xa

yb=2×yc-ya

With numerical values:

xb=2×2-(-1)=4+1=5

yb=2×3-(-5)=6+5=11

Answer: B(5, 11)

Look at the sequence in the table. Which recursive formula represents the sequence shown?

nadezda [96]

Answer:

Option B $a_n=2a_n_-_1+1$

Step-by-step explanation:

we have

$a_1=5\\a_2=11\\a_3=23\\a_4=47\\a_5=95$

<u><em>Verify each recursive formula</em></u>

case A) we have

$a_n=a_n_-_1+1$

For $a_1=5$

Find the value of $a_2$

$a_2=a_1+1$

$a_2=5+1=6$

$6\neq 11$

therefore

The recursive formula A not represent the sequence shown

case B) we have

$a_n=2a_n_-_1+1$

For $a_1=5$

Find the value of $a_2$

$a_2=2a_1+1$

$a_2=2(5)+1=11$ ---> is ok

For $a_2=11$

Find the value of $a_3$

$a_3=2a_2+1$

$a_3=2(11)+1=23$ ---> is ok

For $a_3=23$

Find the value of $a_4$

$a_4=2a_3+1$

$a_4=2(23)+1=47$ ---> is ok

For $a_4=47$

Find the value of $a_5$

$a_5=2a_4+1$

$a_5=2(47)+1=95$ ---> is ok

therefore

The recursive formula B represent the sequence shown

case C) we have

$a_n=a_n_-_1+6$

For $a_1=5$

Find the value of $a_2$

$a_2=a_1+6$

$a_2=5+6=11$ ---> is ok

For $a_2=11$

Find the value of $a_3$

$a_3=a_2+6$

$a_3=11+6=17$

$17\neq 23$

therefore

The recursive formula C not represent the sequence shown

case D) we have

$a_n=2a_n_-_1-1$

For $a_1=5$

Find the value of $a_2$

$a_2=2a_1-1$

$a_2=2(5)-1=9$

$9\neq 11$

therefore

The recursive formula D not represent the sequence shown

case E) we have

$a_n=5a_n_-_1+1$

For $a_1=5$

Find the value of $a_2$

$a_2=5a_1+1$

$a_2=5(5)+1=26$

$26\neq 11$

therefore

The recursive formula D not represent the sequence shown
