14(0.89)^x+4.5 =162

lisabon 2012 [21]

$14(0.89)^{x + 4.5} = 162$
$\frac{14(0.89)^{x + 4.5}}{14} = \frac{162}{14}$
$0.89^{x + 4.5} = 11\frac{4}{7}$
$ln(0.89^{x + 4.5}) = ln(11\frac{4}{7})$
$(x + 4.5)ln(0.89) = ln(11\frac{4}{7})$
$\frac{(x + 4.5)ln(0.89)}{ln(0.89)} = \frac{ln(11\frac{4}{7})}{ln(0.89)}$
$x + 4.5 = -2101.14032500$
$x = 2105.64032500$

Solve for x. Please:)

Answer:

x = 3

Step-by-step explanation:

The smaller triangle and larger one are similar, so corresponding sides are proportional.

8/4 = (8 +(x -1))/5

10 = x +7 . . . . . . . . . multiply by 5 and simplify

3 = x . . . . . . . . . subtract 7

Alternate solution

The short segments are also proportional:

(x -1)/(5 -4) = 8/4

x -1 = 2 . . . . simplify

x = 3 . . . . . . add 1
