const2013 [10]
For T = 89.5 degrees C:
E(t) = 1100(90 - 89.5) + 520(90 - 89.5)^2= 1100(0.5) + 520(0.5)^2= 550 + 130= 680 m
For T = 90 degrees C:
E(t) = 1100(90 - 90) + 520(90 - 90)^2= 0 + 0= 0 m (meaning that boiling point is 90 degrees C at ground level)

<u>Given </u><u>:</u><u>-</u>

  • The slope of the line through points (3,y) and (4,10) is 7 .

<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>

  • The value of y .

<u>Solution</u><u> </u><u>:</u><u>-</u>

As we know that the slope of the line is difference of ordinate divided by the difference of absicca as ,

\longrightarrow m = y -10 / 3 - 4

\longrightarrow 7 (-1) = y -10

\longrightarrow -7 = y -10

\longrightarrow y = 10 -7

\longrightarrow y = 3

<u>Hence</u><u> the</u><u> required</u><u> answer</u><u> is</u><u> </u><u>3.</u>

Area of the large semicircle

= \pi{r}^{2}  \div 2

=  \frac{22}{7}  \times 12 {}^{2}  \times  \frac{1}{2}

=  \frac{11}{7}  \times12 \times 12

=  \frac{11}{7}  \times 144

= 226.28

Area of the small semicircle

= \pi  {r}^{2}  \div 2

=  \frac{22}{7}  \times 6 {}^{2}  \times  \frac{1}{2}

=  \frac{11}{7}  \times 6 \times 6

=  \frac{11}{7}  \times 36

= 56.57

Area of the figure

= 226.28 - 56.57

= 169.71 {cm}^{2}
