ANSWER:

<u>On solving equation by quadratic formula method, we get</u>

D = b² – 4ac

  • (–5)² – 4 × 1 × 3
  • 25 – 12
  • 13

D > 0, so it has real roots.

Now, x = – b ± √D/2a

  • – 5 ± √13/2

So, <u>Correct choice</u> - [A] & [C].

Answer:

solving equation by quadratic formula method, we get:

D = b² - 4ac

=(-5)² - 4 × 1 × 3

=25-12=13

D> 0,

so it has real roots.

x=- b ± √D/2a

- 5 ± √13/2

Correct choice [A] and [C].

Answer: Choice A) $4500.33

---------------------------------------------------------------------

Explanation:

The formula you'll use is
F = P*(1+r)^t

where
F = final amount
P = initial amount
r = growth rate (in decimal form)
t = time in years

In this case,
F = unknown (this is what we're trying to figure out)
P = 3046 
r = 0.05 (since 5% = 5/100 = 0.05)
t = 8

Plug those three known values into the formula and evaluate

F = P*(1+r)^t
F = 3046*(1+0.05)^8
F = 3046*(1.05)^8
F = 3046*1.4774554
F = 4500.3291484
F = 4500.33 ... round to the nearest penny
