Multiply 8.88x10 to the 4th power. explain the shift of the digits and the change in the value of each digit
option a. 4, 4.5, 5, 5.5
left point: a=x=4
right point: b=x=6
width of each of the four equal intervals: w=2/4→w=0.5
the first left endpoint is x1=a→x1=4
the second left endpoint is x2=x1+w→x2=4+0.5→x2=4.5
the third left endpoint is x3=x2+w→x3=4.5+0.5→x3=5
the fourth left endpoint is x4=x3+w→x4=5+0.5→x4=5.5
then, the list is: x1, x2, x3, x4 = 4, 4.5, 5, 5.5
0.1515.. * 100 = 15.
0.1515.. * 1 = 0.
0. * 99 = 15
answer is 15/99.
to find the intercepts, that is where the line crosses the x and y axes
• let x = 0, in the equation for y- intercept
• let y = 0, in the equation for x- intercept
x = 0 : - 15y = 60 ⇒ y = - 4 ← y- intercept
y = 0 : 3x = 60 ⇒ x = 20 ← x- intercept
i'm assuming it's looking for the missing length, which should be 4cm
hope this !
