Answer:
51
Step-by-step explanation:
when n=1
<h2><u><em>t 1=1 </em></u></h2>
<u><em>when n=2</em></u>
<u><em>t2=4</em></u>
<u><em>as first term is 1 and second term is 4 so the common difference is 3 ,for 6 term if you put this in formula for sum to the n term you will get 51 </em></u>
<u><em>t1 =1</em></u>
<u><em>d=3</em></u>
<u><em>n=6 </em></u>
<u><em>than S6=51 </em></u>

Answer:
line1:y=2x+3
Gradient1=2
Let line2 be the line passes through (-4,1)and perpendicular to line1.
Because line2 and line1 are perpendicular, (gradient of line2) (gradient of line1) =-1
Gradient of line2=-1/2
Equation of line2:y-y1 =m(x-x1)
:y-1 =(-1/2)[x-(-4)]
:(y-1)(-2)=(x+4)
:-2y+2 =x+4
:-2y+2-x-4=0
:-x-2y-2 =0
:x+2y+2 =0
*notes:gradient=m
Answer:
40%
Step-by-step explanation:
14 - 10 = 4
4/10 = 0.4
