-22/15 = -1 and 7/15

Hmm that's interesting...

i⁵ = (i i i i i) = (i )(i i)(i i) = (i)(-1)(-1) = i

So the correct answer is i, I don't know why " 1i⁵ " gives you 1.

The formula for volume of a pyramid is:

$V = \frac{1}{3}BH$

Where B is the area of the base and H is the height.

The base is just a square with side length 723 ft, so the area of the base is just 723² = 522,729 sq. ft.

The height is 341 ft.

B = 522,729

H = 341

Literally just plug this into the formula to get the answer.

0.8333… ≈ 0.83

Let's split this big shape into four easier shapes: two triangles on top, one triangle on the left side, and a rectangle connecting them. Then all we have to do is find the areas of each shape and add them together.

You can just find the base and height by counting the squares on the grid. Remember that in a triangle the height is the length of a line drawn at a right angle from the base to the angle opposite the base.

Starting with the top left triangle.

A = (1/2)(B)(H)

A=(1/2)(3)(2)

A= 3 square units

Next let's do the top right triangle:

A = (1/2)(6)(1)

A = 3 square units

Next let's do the triangle on the left side:

A = (1/2)(6)(2)

A = 6 square units

Lastly let's find the area of the rectangle:

A = BH

A = (7)(6)

A = 42 square units.

Now to add them all together: 3 + 3 + 6 + 42 = 54 square units

If you're asking how to do it on this calculator, this is how:

First type the number you want raised to the exponent.

Next click " x^y "

Next click " ( "

Next type the numerator of the exponent.

Next click " ÷ "

Next type the denominator of the exponent.

Next click " ) "

Next click " = "

Point A is where you're standing. Point B is the first tower. Point C is the second tower.

First let's find angle B using the law of cosines.

2420² = 5050² + 6000² - (2)(5050)(6000)(cosB)

5856400 = 61502500 - 60600000cosB

-55646100/-60600000 = cosB

0.91825 ≈ cosB

B ≈ 23.328°

So the angle that I think the problem is asking for is approximately 23.3°.

Next we can find x.

cosB=x/5050

0.91825 ≈ x/5050

x ≈ 4637.163

So the position east of the tower is approximately 4,637.2 feet

Next we can find y.

sinB=y/5050

0.39599 ≈ y/5050

y ≈ 1999.771

So the position north of the tower is approximately 1,999.8 feet.

1 ÷ 3/4

keep, change, flip

= 1 * 4/3

= 4/3
