When T= 13°C and v = 34 km/h
W = 13.12 + 0.6215(13) - 11.37(34)^0.16 + 0.3965(13)(34)^0.16 = 13.12 + 8.0795 - 11.37(1.7581) + 5.1545(1.7581) = 21.1995 - 19.9893 + 9.0620 = 10.27°C.

If T decrease by 1°C (T = 12°C), then
W = 13.12 + 0.6215(12) - 11.37(34)^0.16 + 0.3965(12)(34)^0.16 = 8.95°C
Therefore, W decreased by 10.27°C - 8.95°C = 1.3°C

If v increases by 1 km/h (v = 35 km/h), then
W = 13.12 + 0.6215(13) - 11.37(35)^0.16 + 0.3965(13)(35)^0.16 = 10.22°C
Therefore, W decreaseb by 10.27°C - 10.22°C = 0.05°C

Juan is making a model out of rhombi. Each rhombus will be connected to the one before it. Each rhombus will be 6 inches tall an
love history [14]

He will need 12 sq. inches of Paper for each rhombus.

Given: 6 inches tall and 4 inches wide.

so, Length of the diagonals are 6 and 4 inches respectively.

Refer to figure.

The two diagonals cuts the rhombus into four equal parts, so

Area of one rhombus = 4 x (area of 1 part of the rhombus)

Now,

Area of 1 part of the rhombus = \frac{1}{2} x 3 x 2

                                                  = 3 sq. inches

Area of one rhombus = 4 x 3 = 12 sq. inches

Hence, 12 sq. inches of Paper is needed for each rhombus.
