Casey burrows 3200 for a computer system at a rate of 4.25% per year. How much simple interest will he owe if he takes 4 months to repay the loan? Round to the nearest cent.
Answers
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...

Write an equation for a line parallel to y = − 2 x + 4 and passing through the point ( 2 , 1 )
Answers
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.

simplify the radical and use the imaginary unit i.
Answers
Answer:
√
−
49
=
7
i
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
)
=
−

Then we find:
(

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:
√
−

=

The question remains: Where does

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
)
=
