Which equation represents exponential growth?

2 answers:

8 0

Growth means a base for exponentiation bigger than 1 (in absolute value), otherwise it's decay.

Only the first choice has a base biggerthan 1. The last choice is equivalent to $f(x)=5 ( \frac 1 6)^x$ so has a base less than 1.

Answer: A

Note how answer A has the form (constant)(constant greater than 1)^exponent. This is how you recognize expo growth. The other 3 answer choices are disqualified because their bases {0.11, 1/2, 1/6} are fractions between 0 and 1.

The correct answer is A.

Answer:

=> Apply law of cosine

$c^2=a^2+b^2-2abcos\left(C\right)$

=> input value

$z^2=6.5^2 + 9.4^2-\left(6.5\right)\left(9.4\right)\left(cos\left(131\right)\right)$

=> simplify

$z=\sqrt{\left(6.5^2+\:9.4^2\right)-\left(6.5\right)\left(9.4\right)\left(-0.65605902899\right)}$

=> calulcation

$z=\sqrt{-61.1\cos \left(131^{\circ \:}\right)+130.61},\:z=-\sqrt{-61.1\cos \left(131^{\circ \:}\right)+130.61}$

=> apply rule: Distance must be greater than 0

x ^ 2 = 144

x = 12, x = -12

Check:

12 * 12 = 144

-12 * -12 = 144
