What is the distance from the origin (0,0) to the point (34,-78)
pantera1 [17]

Given coordinates (0,0)  and (34,-78).

\mathrm{Compute\:the\:distance\:between\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}

We \ have\ x_1=0, x_2=34, y_1=0 \ and \ y_2=-78.

\mathrm{The\:distance\:between\:}\left(0,\:0\right)\mathrm{\:and\:}\left(34,\:-78\right)\mathrm{\:is\:}

=\sqrt{\left(34-0\right)^2+\left(-78-0\right)^2}

=2\sqrt{1810}

Distance = 2(42.544) ≈ 85.09.

Therefore, distance from the origin (0,0) to the point (34,-78) is 2\sqrt{1810} \ or 85.09 units.

Find the next 3 terms in the series 3+12+48+...
devlian [24]
The next three terms are 192, 768, and 3072.

Each number is multiplied by 4 and its product becomes an addend.

     3 x 4 = 12
   12 x 4 = 48
   48 x 4 = 192
 192 x 4 = 768
 768 x 4 = 3072

3 + 12 + 48 + 192 + 768 + 3072 +....

The mean is the average, so I added up all the numbers and divided that by the number of tests:
Sara's mean: 78
Lee's mean: 78
