If you have to find Lateral Superficial Area just do P (perimeter of base) * h

So (8+19+10+7) * 8 = 44*8 = 352 cm^2

If you have to find Total Superficial Area the formule is LA + 2[(B+b)*h/2]

TA = 352 + 2[(19*8)/2] = 352+2(76) = 352+152 = 504 cm^2

ANSWER

$f(1) = - 34$

$f(n) = f(n - 1) + 13$

EXPLANATION

The given sequence is;

-34,-21,-8,5,....

The first term of the sequence is

$f(1) = - 34$

The common difference is

$d = 5 - - 8$

$d = 5 + 8 = 13$

The recursive definition is given by;

$f(n) = f(n - 1) + d$

$f(n) = f(n - 1) + 13$

for n=2,3,4,...

What is the equation of a line that passes through the points (–3, 4) and (2, 8)?

Mrac [35]

Answer:

$\frac{y - 4}{x - ( - 3)} = \frac{8 - 4}{2 - (- 3)} \\ \frac{y - 4}{x + 3} = \frac{4}{5} \\ 5(y - 4) = 4(x + 3) \\ 5y - 20 = 4x + 12 \\ \boxed{4x - 5y + 32 = 0}$

<h2>4x-5y+32=0 is the right answer.</h2>
