Simplify and express the answer in scientific notation

It's a fraction. At the numerator we have : -5+9×4-2+(8-3)×6 = -5 + 36 -2 + 5×6 = -5 +36-2 +30= 31-2+30 = 29+30= 59

59/2 = 29.5 +3 = 32.5

Answer:

x = 120°

The triangle is an equilateral triangle and all the angles in an equilateral triangle equal 60°.

Straight lines have 180° angles.

180 -  60 = 120

Answer:

$45.33

Step-by-step explanation:

First we find 4.25% of $3200 to find the interest in 1 year.

For simple interest, use this formula:

I = Prt

where

I = amount of interest

P = principal amount (the amount deposited or borrowed)

r = annual interest rate

t = number of years

We have

I = ?

P = $3200

r = 4.45% = 0.425

t = 1 year

I = ($3200)(0.0425)(1)

I = $136

The interest in 1 year is $136.

Now we convert 4 months to years

1 year = 12 months

4/12 = 1/3

4 months are only 1/3 of a year, so he pays only 1/3 of the interest of an entire year.

1/3 * $136 = $136/3 = $45.3333...

Answer:

12, 14, 16, and 18 are all even numbers between 10 and 19

Step-by-step explanation:

They are all even numbers because they end in 2, 4, 6, or 8. 0 is considered neither even nor odd.

Answer:

12 is an even number because it is divisible by 2

Answer:

x=2y

Step-by-step explanation:

y=-2x+4 is perpendicular to the line which passes through (2,1). We know that we can use the formula y=mx+c to find the gradient of the line with the equation y=-2x+4, which will give you -2. The product of the gradient of two perpendicular lines is always -1. So the gradient of the line which passes through (2,1 ) is -½.

Now,to find the equation of the line,we use the formula y-y1=m(x–x1)which will give you the answer 2y=x when solved.

Answer:

  60°

Step-by-step explanation:

The exterior angle is equal to the sum of the remote interior angles:

  100° = 40° +∠B

  60° = ∠B . . . . . . . . . . . . . subtract 40° from both sides

Answer:

x = 1

Step-by-step explanation:

I'm going to convert this to decimal to make it easier to type

Since x = 1, there is no need to include it in the equation

1/4 - 8 = -7.75 + 12 = 4.25

-0.75 + 5 = 4.25

Answer:

By simplifying both sides of the equation, then isolating the variable.

Answer:

Explanation:

A square root of a number  

n

is a number  

x

such that  

x

2

=

n

Note that if  

x

is a Real number then  

x

2

≥

0

.

So any square root of  

−

49

is not a Real number.

In order to be able to take square roots of negative numbers, we need Complex numbers.

That's where the mysterious number  

i

comes into play. This is called the imaginary unit and has the property:

i

2

=

−

1

So  

i

is a square root of  

−

1

. Note that  

−

i

is also a square root of  

−

1

, since:

(

−

i

)

2

=

(

−

1

⋅

i

)

2

=

(

−

1

)

2

⋅

i

2

=

1

⋅

(

−

1

)

=

−

1

Then we find:

(

7

i

)

2

=

7

2

⋅

i

2

=

49

⋅

(

−

1

)

=

−

49

So  

7

i

is a square root of  

−

49

. Note that  

−

7

i

is also a square root of  

−

49

.

What do we mean by the square root of  

−

49

For positive values of  

n

, the square root is usually taken to mean the principal square root  

√

n

, which is the positive one.

For negative values of  

n

, the square roots are both multiples of  

i

, so neither positive nor negative, but we can define:

√

n

=

i

√

−

n

With this definition, the principal square root of  

−

49

is:

√

−

49

=

i

√

49

=

i

Footnote

The question remains: Where does  

i

come from?

It is possible to define Complex numbers formally, as pairs of Real numbers with rules for arithmetic like this:

(

a

,

b

)

+

(

c

,

d

)

=

(

a

+

c

,

b

+

d

)

(

a

,

b

)

⋅

(

c

,

d

)

=

(

a

c

−

b

d

,

a

b

+

c

d

)

These rules for addition and multiplication work as expected with commutativity, distributivity, etc.

Then Real numbers are just Complex numbers of the form  

(

a

,

0

)

and we find:

(

0

,

1

)

⋅

(

0

,

1

)

=

(

−

1

,

0

)

That is  

(

0

,

1

)

is a square root of  

(

−

1

,

0

)

Then we can define  

i

=

(

0

,

1

)

and:

(

a

,

b

)

=

a

(

1

,

0

)

+

b

(

0

,

1

)

=

a

+

b

i
