-3(7+5) 3
———-


7+5= 12

-3 x 12 = 36

3x3 = 9

36/9

+9 (2) = 18

36 = 4 wholes

18 + 4 = 22

Of course, I’m not 100% sure if it’s correct. But it’s what I got.

The terminal tower in cleveland ohio is 239 ft shorter than key tower also in cleveland the total heights of the two buildings i
Nutka1998 [239]
T + k = 1655
k = t + 239

now we sub
t + t + 239 = 1655
2t + 239 = 1655
2t = 1655 - 239
2t = 1416
t = 1416/2
t = 708 ft <== terminal tower

k = t + 239
k = 708 + 239
k = 947 ft <=== key tower

Answer:

(D). \frac{\sqrt{2} }{8} <em>cis</em> \frac{47\pi }{36}

Step-by-step explanation:

cis \alpha × cis \beta = cis ( \alpha + \beta )

~~~~~~~

\frac{\sqrt{6} }{6} cis \frac{5\pi }{9} × \frac{\sqrt{3} }{4} cis \frac{3\pi }{4} = ( \frac{\sqrt{6} }{6} × \frac{\sqrt{3} }{4} )[cis ( \frac{5\pi }{9} + \frac{3\pi }{4} )] = \frac{\sqrt{2} }{8} <em>cis</em> \frac{47\pi }{36}

A circle has a diameter AB, and its center is at (-3, 3). Point A is at (1/2,6). Where is point B located?
erastovalidia [21]

The point B is located at (-6.5, 0)

<h3>How to determine where is point B located?</h3>

The points are given as:

A = (1/2, 6)

Center = (-3, 3)

The center is calculated as:

Center = 0.5 * (x1 + x2, y1 + y2)

So, we have:

(-3, 3) = 0.5 * (1/2 + x, 6 + y)

This gives

(-6, 6) = (1/2 + x, 6 + y)

Solve for x and y

1/2 + x = -6

6 + y = 6

This gives

x = -6.5

y = 0

Hence, the point B is located at (-6.5, 0)
