Aaron is correct because there is the set amount of dollars needed which is X. Since the question is asking the number of dollars she can earn AND meet her goal that means that the arrow should continue to go up.

PLEASE HELP ME! Find the cube roots of 125(cos 288° + i sin 288°).

shutvik [7]

◆ COMPLEX NUMBERS ◆

125 ( cos 288 + i sin 288 ) can be written as -

125.e^i( 288)
125.e^i( 288 +360 )
125.e^i( 288+ 720)

[ As , multiples of 360 can be added to an angle without changing any trigonometric functions or sign ]

To find the cube root , take the cube root of above 3 expressions ,

We get -
5 e^( i 96 )
5 e^( i 216 )
5 e^( i 336 )

Now using Euler's formula , We rewrite above as -

5 ( cos 96 + i sin 96 )
5(c os 216 + i sin 216 )
5 ( cos 336 + i sin 336 ) Ans.

What is the equation of the line that passes through (-3, -1) and has a slope of 2/5? Put your answer in slope-intercept form.

Zanzabum

Hi there!

The general formula of A line in slope-intercept form is the following:
$y = mx + n$

In this formula m represents the slope of the line. Therefore, we can conclude that m = 2/5.
$y = \frac{2}{5} x + n$

We also know that the line passes through the point (-3, -1) and we can therefore substitute this coordinate into the formula of the line.
x = -3 and y = -1

$- 1 = \frac{2}{5} \times - 3 + n$

Multiply first.
$- 1 = - 1\frac{1}{5} + n$

And finally add 1 1/5 to both sides of the equation.
$\frac{1}{5} = n$

We can now switch sides.
$n = \frac{1}{5}$

Now we've found our value of n, which we can substitute into the formula of our line. Hence, in slope-intercept form, we find the following:
$y = \frac{2}{5} x + \frac{1}{5}$

What is the equation for the line that has a slope of 0 and passes through the point (3, 7)?

Harrizon [31]

Answer:

Step-by-step explanation:

PART 1

y=mx+b

m is slope and slope is 0 sooo

y=0x+b

it passes through (3,7)

7=0(3)+b

7=0+b

b=7

y=0x+7

so just y=7

PART 2

y=mx+b

y=1/5x+b

1/2=1/5(-2/3)+b

1/2=-2/15+b

1/2+2/15=b

15/30+4/30=b

19/30=b

y=1/5x+19/30
