What is the slope of a line that is perpendicular to the line y = 1?
Katyanochek1 [597]
The line        Y = 1    is a horizontal line; its slope is zero.

A line perpendicular to   Y = 1   is a vertical line.
Its slope is undefined.
(This does NOT mean that it's infinite, or anything else.
The slope of a vertical line is undefined.  It doesn't have
a name or a symbol.  It's nothing.)

0.04 with 4 repeating as a fraction. Not the 04 repeating just the 4 is repeating. What is the answer???
Dmitriy789 [7]

Answer:

2/45

Step-by-step explanation:

0.04... is the same as 0.1 * 0.4... because we are moving it up a decimal place, it's the same as multiplying by ten: we needed to multiply by a tenth to cancel that out. 0.4... is the same as 4/9 and 0.1 is the same as 1/10. We can rewrite the expression above as: (\frac{1}{10} )(\frac{4}{9} ). Multiplying the two fractions results in 4/90 which can be simplified to 2/45.

I wish to have $10,000 at the end of 8 yers in a bank offering a simple interest rate of 7.5% per year. How much should I deposi
kolezko [41]

Answer:

You have to invest  $6,250

Step-by-step explanation:

very simple applying the simple interest formula which is

A = P (1 + rt)

Given data

A, final amount =  $10,000

P, initial principal balance=  ?

r, annual interest rate = 7.5%

t, time (in years)= 8 years

we can substitute our given data to find the principal needed.

10000= P(1+0.075*8)\\\10000= P(1.6)\\\

Divide both sides by 1.6 we have

P= \frac{10000}{1.6} \\\P= 6250

P= $6,250
