Question

(1 point) Find the area under the curve y = 1/(7x) from 1 to 2 = t and evaluate it for t = 10,4 = 100. Then find the total area under this curve for 2 > 1. (a)t = 10 (b) t = 100 (c) Total area

can you explain the workings

Answer 1

Quis son Given y = - 723 We will find Area (I) from x=1 to x=t Area (I= S y dx x=1 t -) IS y da Now: By – t. I = S da 7x3 = I= I - 3+1

-) I= + HC = I= - [-] #n +2 -) I= ise (AP-1) t = 10 Nuw By 3 - 1 = I Mallop (10²) = IS 1 x 99 100 =) I = 99 luoto

t=10o BY Eqh 3 - I = 14x(100)? (1002-) =) 9999 I = 140000 tutal Arca for X21 Hac t @ ho : I = 14+2 08 I = (-) T + When too I 4 (1-0) =) 1 14
