Answer:

Associative property is illustrated.

Step-by-step explanation:

we have been given:

(2+3.4)+6=2+(3.4+6)

This is the associative identity which is:

a+(b+c)=(a+b)+c

Here, we have a=2, b=3.4, c=6

On comparing the values with associative property we get:

(2+3.4)+6=2+(3.4+6)

We club two numbers b and c first and then a and b in same bracket.

Two variable quantities A and B are found to be related by the equation A^3 + B^3 = 9. What is the rate of change dA/dt at the m

Amanda [17]

3A^2 dA/dt + 3B^2 dB/dt = 0

If A=2, then 8+B^3=9, B=1

12 dA/dt + 9 = 0

dA/dt = -3/4

Vector a = 3i + mj, vector b = 2i - nj and vector c = ni + 8j. If a and b is perpendicular to each other and b and c are paralle

Tatiana [17]

May be you know it or not a two dimensional vector can be represented by a complex number.Why i have written this statement you will just know when you will see its solution

a = 3i + mj and b = 2i - nj are perpendicular to each other ,so their dot product

will be zero.

$i.e a.b = 0\\(3i + mj) .(2i - nj)=0\\6-mn=0\\mn=6$ j

vector b = 2i - nj and vector c = ni + 8j are parallel to each other. $2i - nj = k (ni + 8j)2/n = -n/8n^{2} =-16n=4i$ j

mn = 6

so m=6/4i

m=3/2i

m=3i^{4}/2i

m = 3i^{3}/2

m= -3i/2 as(i^{4} =1, i^{3} = -i[/tex][/tex]

Answer:

a. 10, 16

b. 211, 311

c. 10 , 12.5

d. -13, -22

Step-by-step explanation:

In an arithmetic sequence, there is a constant difference, which is the difference between a term and the previous term. We find the constant different for each sequence, and we add it to the second term to find the third term. Then we add the constant difference to the third term to find the fourth term.

4 - (-2) = 6

3rd term: 4 + 6 = 10

4th term: 10 + 6 = 16

111 - 11 = 100

3rd term: 111 + 100 = 211

4th term: 211 + 100 = 311

7.5 - 5 = 2.5

3rd term: 7.5 + 2.5 = 10

4th term: 10 + 2.5 = 12.5

-4 - 5 = -9

3rd term: -4 + (-9) = -13

4th term: -13 + (-9) = -22
