What is the value of i5 1 −i i −1

lozanna [386]

I’m assuming you mean: What is the value of i^5? This symbol (^) means that the 5 is an exponent of five.
If you did mean i^5, then the answer is i.

or to put it in simpler terms,
i^5=i

I hope this helped!

Find the area *15 points*

vova2212 [387]

Answer:

The answer to your question is 780 ft²

Step-by-step explanation:

- Divide the figure into two sections an upper part and a lower part.

- Area of the upper part = base x height

= 40' x 18'

= 720

-Area of the lower part

base = 40' - 30' = 10'

height = 24' - 18' = 6'

Area = 10 x 6 = 60

- Total area = Area Upper part + Area lower part

= 720 + 60

= 780 ft²

Beatrice calculated the slope between two pairs of points.

kumpel [21]

Answer:

The answer in the procedure

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

step 1

Find the slope between (-3, -2) and (1, 0)

$m=\frac{0+2}{1+3}$

$m=\frac{2}{4}=\frac{1}{2}$

Find the equation of the line

$y-y1=m(x-x1)$

with m and the point (1,0)

substitute

$y-0=\frac{1}{2}(x-1)$

$y=\frac{1}{2}x-\frac{1}{2}$

step 2

Find the slope between (-2, -1) and (4, 2)

$m=\frac{2+1}{4+2}$

$m=\frac{3}{6}=\frac{1}{2}$

Find the equation of the line

$y-y1=m(x-x1)$

with m and the point (4,2)

substitute

$y-2=\frac{1}{2}(x-4)$

$y=\frac{1}{2}x-2+2$

$y=\frac{1}{2}x$

Compare the equation of the two lines

The two lines are parallel, because their slope is the same, but are different lines

therefore

Beatrice's conclusion is incorrect

All of these points are not on the same line, because are different parallel lines

The slope between (-2,-1) and (1,0) is equal to $\frac{1}{2}$
