Given

Find

Length of AC

Explanation

as we have given right angle triangle

by pythagoras theorem ,

$AC^2=AB^2+BC^2$

AB = 6 + 6 = 12

so ,

$\begin{gathered} AC^2=12^2+(6.4)^2 \\ AC^2=144+40.96 \\ AC^2=184.96 \\ AC=\sqrt{184.96} \\ AC=13.6 \end{gathered}$

Final Answer

Hence , the length of AC is 13.6 . So , the correct option is 4

1.) C(t) = -0.30(t - 12)^2 + 40
for t = 12: C(12) = -0.30(12 - 12)^2 + 40 = -0.30(0)^2 + 40 = 40°C
For t = 24: C(24) = -0.30(24 - 12)^2 + 40 = -0.30(24 - 12)^2 + 40 = -0.30(12)^2 + 40 = -0.30(144) + 40 = -43.2 + 40 = -3.2°C

4.) F(t) = 9/5 C(t) + 32
for C(t) = 40°C: 9/5 (40) + 32 = 72 + 32 = 104°F
for C(t) = -3.2°C: 9/5(-3.2) + 32 = -5.76 + 32 = 26.24°F

5.) F(t) = 9/5 C(t) + 32 = 9/5 (-0.30(t - 12)^2 + 40) + 32 = -0.54(t - 12)^2 + 72 + 32 = -0.54(t - 12)^2 + 104
