Please no wrong answers <br>what to do next??

Finger [1]

Step-by-step explanation:

I am not sure what you want to calculate as ultimate goal.

but your have an error already in your third line in the picture.

(3-6i)(2-4i) = 3×(2-4i) - 6i(2-4i)

you had there a "+" instead of a "-".

and then you made subsequent mistakes in every line, some of them are funnily bringing you more back to the real result (e.g. -12i + 12i would be 0 and not -24i, but if the third line would have been correct, then yes, -24i is actually needed) - but not completely.

= 3×2 - 3×4i - 6i×2 + 6i×4i =

= 6 - 12i - 12i + 24×-1 = 6 - 24i - 24 = -24i - 18

then in the last 3 lines you kind of lose it completely. I am absolutely not sure, what you are calculating, and where the "+" cube from instead of "×" (multiplications) and such.

(3+6i)(2+4i) = 3×2 + 3×4i + 6i×2 + 6i×4i =

= 6 + 12i + 12i + 24×-1 =

= 6 + 24i - 24 = 24i - 18

is that what you wanted to show ?

The taxi fare in Gotham city is 2.40 for the first mile and additional mileage charged at the rate of .20 for each additional.1

Lemur [1.5K]

Answer:

28 miles

Step-by-step explanation:

Let

x ----> the number of miles

y ----> the total cost of taxi fare

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate

b is the y-intercept or initial value (value of y when the value of x is equal to zero)

In this problem we have

The unit rate or slope is equal to

$m=\$0.20\ per\ mile$

The initial value or y-intercept is equal to

$b=\$2.40$

substitute

$y=0.20x+2.40$

Find out how many miles can you ride for $10

Subtract $2 of the tip

we have

y=$10-$2=$8

substitute in the linear equation

$8=0.20x+2.40$

Solve for x

$0.20x=8-2.40$

$0.20x=5.60$

If you wanted to make the graph of y = 6x +7 less steep which equation could you use

algol [13]

Y=x+7 would make the slope less steep because the rate is not as big as 6.

Find the distance between the origin and the point R = (9,7,8). The distance is: Ensure that you use at least 4 decimal place ac

gregori [183]

Answer:

The distance between the origin and the given point is 13.9283 units.

Step-by-step explanation:

The coordinates of origin are (0,0,0)

We are given a point R(9,7,80

The distance formula:

$\sqrt{(y_1 -x_1)^2 + (y_2 -x_2)^2 + (y_3 -x_3)^2}$ , where $(x_1, x_2, x_3)$ are coordinates of one point and $(y_1, y_2, y_3)$ are coordinates of other point.

Putting the values as:

$y_1 = 9, y_2 = 7, y_3 = 8\\x_1 =0, x_2 = 0, x_3 = 0$

We get d = $\sqrt{81 + 64 + 49}$

d = $\sqrt{194}$

d = 13.9283

Thus, the distance between the origin and the given point is 13.9283 units.
