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.

A-2.5
B 5-151
C-13+51
D|-81-2

Answers

Answer:

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.

The table shows the fees to park in a parking lot.
first hour = $1
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

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

Review: Jen sells flowers. She charges $2 per flower plug a $3 flat delivery fee. How many flowers did she deliver if she made $21?

Answers

Answer:

she delivers 9 flower plugs.

Step-by-step explanation:

in a standard equation the equation would be 21 = 2x + 3 and if you isolate the x you would have to first subtract the 3 from both sides and that would leave you with 18 = 2x and then you have to divide both sides by 2 and get 9=x

What is the y-intercept of the line given by the equation y = 8x + 75?
A. (0,75)
B. (0,-8)
C. (0, -75)
D. (0,8)

Answers

Answer:

The answer is A.

Step-by-step explanation:

In a linear equation, y = mx + b where b represent y-intercept.

y-intercept is the point where it touches y-axis, so the value of x is 0.

The y-intercept of the given equation is (0, 75). Therefore, option A is the correct answer.

What is a y-intercept?

In Maths, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.

The given equation of a line is y=8x+75.

To find the y-intercept, set x = 0 and solve for y.

Here, substitute x=0 in y=8x+75, we get

y=8(0)+75

y=75

So, the y-intercept is (0, 75)

Therefore, option A is the correct answer.

If the value of a quarter of a kilogram is ₹ 40, how much money will be the value of 100 grams?

Answers

Answer:

₹16

Step-by-step explanation:

1/4 kg = ₹ 40

1kg = 40×4 = ₹160

1000g = 1kg

100g = 100/1000 kg

= 0.1kg

0.1kg= 0.1×160 = ₹16

First convert 40 grams to kg. A kilogram is 1000 grams, so you divide 40 by 1000 which is .04 kg.

40 grams * 1 kg / 1000 grams = .04 kg

(Note here that 1 kg = 1000 grams meaning that 1 kg / 1000 grams = 1; anything divided by itself is one; therefore, when I multiply by 1 kg / 1000 grams I’m not changing the value, only the units.)

Then you simply multiply the price per kg by the number of kg giving 6.6.

.04 kg * 165 / 1 kg = 6.6

(Oranges are different. You can’t compare apples to oranges.)
