0.0000679 in scientific notation

[tex]6.79 \times 10 {}^{ - 5} [/tex]

Answer: 6.79×10^-5

Step-by-step explanation:

In order to write the given value in scientific notation, we have to bring the decimal point after the first non-zero digit.

So it will become 6.79

Now for the zeros that have been removed we represent them in the form 10^-5.

And it is -5 because we have removed the zeros from the left side of the value. The 10^-5 indicates that we have to move "five points" to the "left side" to get the original value again.

So it is first, 0.0000679

(we make the decimal point jump across four zeros to the right side and then across the 6 which is the first non zero digit, that is 5 jumps in total as indicated by the 10^-5)

Then it becomes:

6.79×10^-5

Answer:

False.

Step-by-step explanation:

Using the property of distribution, (a + b)² will be a² + b², never a² + b.

No, for any two integers a and b, (a + b)² ≠ a² + b is a false statement.

For the given two integers a and b,

The given expression

(a + b)² = a² + b (false statement)

The correct statement is-

(a + b)² = (a + b)(a + b)

(a + b)² = a² + b² +  2ab

Thus, no, for any two integers a and b, (a + b)² ≠ a² + b.

Answer:

9 and 11

Step-by-step explanation:

20 = 9 + 11

Algebraic approach

let the 2 consecutive odd numbers be n and n + 2 , then

n + n + 2 = 20 , that is

2n + 2 = 20 ( subtract 2 from both sides )

2n = 18 ( divide both sides by 2 )

n = 9 and n + 2 = 9 + 2 = 11

The 2 numbers are 9 and 11

Answer:

x = 19.6

Step-by-step explanation:

If we need to find the value of x then first we need to

(7x-25) + (3x +9) = 180  (angles at the same side of transversal will be equal to 180 degree )

10x -16 = 180

10x = 180 +16

10x = 196

x = 196/10

x = 19.6

Step-by-step explanation:

Answer:

m∠1= 80

m∠2= 100

m∠3= 80

Step-by-step explanation:

Given: m∠1= 2x +40

m∠2= 2y +40

m∠3= x +2y

m∠1 +m∠2= 180 (adj. ∠s on a str. line)

2x +40 +2y +40= 180

2x +2y+ 80= 180

2x +2y= 180 -80

2x +2y= 100

2(x +y)= 100

x +y= 100 ÷2

x +y= 50 -----(1)

m∠1= m∠3 (vert. opp. ∠s)

2x +40= x +2y

2x -x +40= 2y

x= 2y -40 -----(2)

Substitute equation (2) into (1):

2y -40 +y= 50

3y= 50 +40

3y= 90

y= 90 ÷3

y= 30

Substitute y= 30 into equation (2):

x= 2(30) -40

x= 60 -40

x= 20

m∠1

= 2x +40

= 2(20) +40

= 40 +40

= 80

m∠2

= 2y +40

= 2(30) +40

= 60 +40

= 100

m∠3

= x +2y

= 20 +2(30)

= 20 +60

= 80

Alternatively, since m∠1= m∠3,

m∠3

= m∠1 (vert. opp. ∠s)

= 80

Answer:

(4,-3)

Step-by-step explanation:

A rotation is when we move a point based on a point of a fixed point called the center. For example, a clock. A clock rotated it's hand around the middle part of the clock.

A 180 degree rotation negate a point if rotated about the origin. 180 degree rotation counter or clockwise doesn't matter when we rotate about the origin. In other words. they are the same.ONLY WHEN WE ROTATE 180 OR 360 degrees.

The rotation formula when rotating 180 degrees is

[tex](xy)[/tex]

goes

[tex]( - x )(- y)[/tex]

In other words, we negate both points to find our new coordinates.

-(-4)=4 and

-3=-3

So our new point is

Step-by-step explanation:

Matrices can be multiplied together if the number of columns in the first matrix equals the number of rows in the second matrix.

A is of order (3 × 2) and B of order (2 × 3 )

Since the 2 in the first and the 2 in the second match , the matrices can be multiplied

The resulting matrix is of order (3 × 3 )

This is obtained from the first 3 in order of A and the second 3 in order of B

Then AB is defined and the resultant matrix is of order 3 × 3
