A=6
d=7
Tn= a+ (n-1)d
216=6+(n-1)*7
n=31
total no. of terms=31
middle term=(31+1)/2
=16th
T16= a+(16-1)d
= 6+(15*7)
=111
therefore the middle term of the AP is 111

3x² - x - 4

On comparing general form of quadratic polynomial ax² + bx + c, we get

a = 3, b = -1 and c = -4

Sum of zeroes = -b / a = - (-1)/3 = 1/3

Product of zeroes = c/a = -4/3

Yogita Ingle 5 years, 7 months ago

2x+3y=12is the standard form for a linear equation. To determine the slope, solve the equation for y in order to convert to the slope-intercept form

y=mx+b, where m is the slope and b

is the y-intercept.

2x+3y=12 Subtract2x from both sides.

3y=−2x+12

Divide both sides by 3.

y=−2/3x+12/3

y=−2/3x+4

The slope is−2/3

Let the unit digit be y & tens digit be x. Original number = (10x+y) After interchanging the digits New number = (10y+x) (10x+y) + (10y+x) = 110 11x +11y = 110 11(x+y)= 110 x+y = 110/11 x+y= 10…………...(1) x= 10-y……………(2) (10x+y) - 10 = 4+ 5(x+y) (10x+y) - 10 = 4+ 5(10) (10x+y) = 4+ 50+10 (10x+y) = 64 10(10-y) +y = 64 100-10y +y= 64 100 -9y = 64 -9y = 64-100 -9y = -36 y= 36/9= 4 y= 4 putting the value of y in eqn 2 x= 10-y x= 10-4 x= 6 Hence , the first number is 6 & second number is 4.
