<h3>Answer:</h3>

d. 4/229 +30/229i

<h3>Explanation:</h3>

Multiply numerator and denominator by the conjuate of the denominator, then simplify.

\dfrac{2}{2-15i}=\dfrac{2}{(2-15i)}\cdot\dfrac{(2+15i)}{(2+15i)}=\dfrac{4+30i}{2^2-(15i)^2}\\\\=\dfrac{4+30i}{4+225}=\dfrac{4}{229}+\dfrac{30}{229}i

What is an equation of the line that is parallel to y=3x−8 and passes through (1, 8) ?
Rudik [331]

Answer:

y=3x+5

Step-by-step explanation:

Since the equation will be parallel, the slope will still be 3.

y=3x+b

Enter the point (1,8) into the equation.

8=3(1)+b

8=3+b

b=5

y=3x+5

Sammy the Sailor swears entirely too much. The following probability distribution shows the number of times Sammy swears per day
malfutka [58]

Full question attached:

Answer and explanation:

A) B2*B10: cell B2 and B10 have the values regular swear costs and number of swears respectively and we need to multiply these two values to get our answer

B) =IF(B10>10,(B10-10)*B3,0): Sam is supposed to pay an extra $2 for swear words over 10 and so we check if his swear words are above 10 and if they are we find out how many they are by subtracting 10 from them and then we multiply the value gotten by the cost for extra swear words($2)

C) =IF(B10<5,B10*B4,0): here we check if swear words are less than 5 and if they are we multiply number of swears words less than by 5 by the cost ($0.50)

D) F10=C10+D10+E10: to calculate total money in jar(F10), we simply add up regular cost(C10), extra cost(D10) and refund(E10)

Find the equation in standard form , of the line passing through points (2,-3) and (4,2)
Fudgin [204]

The form of linear equation that describes line is:

y=sx+n

First we must calculate the slope.

s=\dfrac{\Delta{y}}{\Delta{x}}=\dfrac{2-(-3)}{4-2}=\dfrac{5}{2}

Now it looks a bit more like this:

y=\dfrac{5}{2}x+n

All we need now is to put in y and x from one point doesn't matter which. I'll pick A.

The equation now looks like this:

-3=\dfrac{5}{2}\cdot2+n

Solve for n.

-3=5+n \\n=-8

And finally write the equation.

f(x)=\dfrac{5}{2}x-8

Hope this helps.
