Answer:

  2 + 5i

Step-by-step explanation:

Multiply numerator and denominator by the conjugate of the denominator.

  [tex]\dfrac{(25+19i)}{(5-3i)}=\dfrac{(25+19i)(5+3i)}{(5-3i)(5+3i)}\\\\=\dfrac{68+170i}{34}=\boxed{2+5i}[/tex]

In general, the multiplication proceeds the way it would if i were a variable. The difference is that i² can be replaced by -1.

Answer:

 h(x) =  -x² + 11 x + 2

Step-by-step explanation:

Explanation:-

Given that the functions are  

                                            f(x) = 2 x² - 5x -3

                                            g(x) = x² + 6x -1

               h(x)  = g(x) - f(x)

                      = x² + 6x -1 - (2 x² - 5x -3)

                     = - x² + 6 x +5x -1+3

                    = -x² + 11 x + 2

            h(x) =  -x² + 11 x + 2

Final answer:-

h(x) =  -x² + 11 x + 2

What is the equation of a line, in general form, that passes through point (1,-2) and has a siope of 1/3?

Answers

9514 1404 393

Answer:

  x -3y -7 = 0

Step-by-step explanation:

The general form of the equation for a line is ...

  ax +by +c = 0

where a, b, c are mutually prime and the leading coefficient is greater than zero.

__

The general form equation for a line with slope m = rise/run through point (h, k) can be found by simplifying ...

  rise(x -h) -run(y -k) = 0 . . . . where run has the sign of the slope

For the given point and slope, we have ...

  1(x -1) -3(y -(-2)) = 0

  x -3y -7 = 0

3. Which number is a natural number?
A-2.5
B 5-151
C-13+51
D|-81-2

Answers

Answer:

C

Step-by-step explanation:

A natural number is a number that you would use to count kids in a class for example. Like, 1,2,3,4 and so on. 2.5 is not a natural number since there cant be 2.5 of a student. 5-151 is a negative number and there cant be negative students. -13+51=38. 38 is a natural number. Now, in D it looks like there mightve been a absolute value sign but im not sure. If D has absolute value signs then D works too. Hope I could help.

$70.00 at 5% for 2 years

Answers

Answer:

$7

Step-by-step explanation:

Hey there

to solve this kind of problem we use the formula:

[tex]\frac{p * t * r}{100}[/tex] if we solve it :

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

then, solving our equation

I = 70 × 0.05 × 2 = 7

I = $ 7.00

The simple interest accumulated

on a principal of $ 70.00

at a rate of 5% per year

for 2 years is $ 7.00.

The table shows the fees to park in a parking lot.

second hour = $1.50
each additional hour or part of an hour = $2.
How much does it cost to park for 4 1/2 hours?

Answers

Answer:

$7.50

Step-by-step explanation:

4 1/2 hours total

1st hour = $1.00 ;  3 1/2 hrs remaining

2nd hour = $1.50 ;  2 1/2 hrs remaining

after 2 hours you pay $2 per hour so 2.5 x 2 = $5.00

A collector has 2792 coins
altogether. Half of the coins
are on display. The collector
buys more coins at an auction
so that the coins on display
are now 40% of the collection.
How many coins are bought at
the auction?

Answers

Answer:

3490 coins

Step-by-step explanation:

Given data

Total coins= 2792 coins

Half of the coins are on display

that is 50% are on display

=2792/2

=1396

let the coins bought be x

40% of x= 1396

40/100*x= 1396

0.4x= 1396

x=  1396/0.4

x=3490

Hence 3490 coins were bought
