Answer:

24.9 meters to the nearest tenth.

Step-by-step explanation:

We have 2 similar triangles here so:

21/8 = h/9.5

h = 21* 9.5 / 8

= 24.94 m = the height of the tank.

Answer:

\boxed{24.9375}

Step-by-step explanation:

→ Write out the direct proportion equation

y = kx

→ Substitute in x = 21 and y = 8

8 = 21k

→ Divide both sides by 8 to isolate k

k = 2.625

→ Substitute back into original equation

y = 2.625k

→ Substitute 9.5 for k

y = 2.625 × 9.5 ⇔ 24.9375

ANSWER

x = - 2 \pm i

EXPLANATION

We use the method of completing the squares.

The equation is
3 {x}^{2} = - 12x - 15

We rewrite the above equation to obtain;

3 {x}^{2} + 12x = - 15

We divide through by 3 to obtain;

{x}^{2} + 4x = - 5

We add half the coefficient of
x

to both sides of the equation to get,

{x}^{2} + 4x + {2}^{2} = - 5 + {2}^{2}

The right hand side is now a perfect square.

{(x + 2)}^{2} = - 1

We now take square root of both sides to get;

x + 2 = \pm \sqrt{ - 1}

We add -2 to both sides,

x = - 2 \pm \sqrt{ - 1}

We simplify to obtain,

x = - 2 \pm i
