Since you already answered 'a' and 'b', then 'c' is easy. You know how far behind Aston was when his father crossed the finish line. So that's exactly the head start he needs, in order for them to tie at the finish.

Write your answer as an integer or as a decimal rounded to the nearest hundredth.

Answer:

Step-by-step explanation:

USing SOH CAH TOA

sin theta = opposite/hypotenuse

sin <X = WV/VX

sin <X = 8/9

<X = arcsin(8/9)

<X = arcsin(0.8889)

<X = 62.7 degrees

Hence the value of x is approximately 63degrees

For the following geometric sequence find the recursive formula: {-1, 3, -9, ...}.

vredina [299]

First term (a1) is -1

recursive formula goes like this

$a_n$ is the nth term
$a_{n-1}$ is the term before that

we normally have $a_n=f(a_{n-1})$

we see each term is multipying by -3 to get next one

so that would be
$a_n=-3*a_{n-1}$ where a1=-1

the 3rd option is correct except that it is the explicit formula

so answer is 2nd one
