Given, r = 30cm

h= 80cm

a) 

 $2\pi \times r {}^{2}$ 

=5654.867 cm²

b) volume of cylindrical tank

 $\pi {r}^{2} h$ 

=226194.671 cm2

 $1cm {}^{2} = 1ml$ 

=226194.671ml

=226.195litres

Find the coordinates of the point 3/10 of the way from A to B.

meriva

The horizontal distance from A to the point = 3/10 * 14 = 4.2, so the c coordinate of the point is -3+ 4.2
= 1.2.
Vertical distance = 3/10 * 12 = 3.6
So the y coordinate = -5+ 3.6
= -1.4.
Answer is (1.2, -1.4)

Y=-3x+2 Y=2x-3 How to solve these equations using substitution or elimination.

Finger [1]

Substitution:
$y=-3x+2 \\
y=2x-3 \\ \\
\hbox{substitute -3x+2 for y in the 2nd equation and solve for x:} \\
-3x+2=2x-3 \\
-3x-2x=-3-2 \\
-5x=-5 \\
x=1 \\ \\
\hbox{substitue 1 for x in one of the equations and solve for y:} \\
y=2 \times 1-3 \\
y=2-3 \\
y=-1 \\ \\
(x,y)=(1,-1)$

Elimination:
$y=-3x+2 \ \ \ |\times (-1) \\
y=2x-3 \\ \\
-y=3x-2 \\
\underline{y=2x-3} \\
y-y=3x+2x-2-3 \\
0=5x-5 \\
5=5x \\
x=1 \\ \\
y=2 \times 1-3=2-3=-1 \\ \\
(x,y)=(1,-1)$
