The answer to your question is D

First, you multiply the two decimal numbers, without the x 10 part:

3.84 x 2

7.68

Next, you add the exponents of the 10's:

5 + 6

11

Therefore, it is 7.68 x 10^11

Hope it helps and have a great day!

elixir [45]

Answer:

L = 14/\sqrt2} <u>OR</u> 9.899

Step-by-step explanation:

cos(angle) = adjacent/ hypotenuse

hypotenuse = length of ladder

adjacent = 7 feet

length of ladder = L

1/L = cos(45)/7

L = 7/cos(45)

<u><em>MAKE SURE CALCULATOR IS IN DEGREE MODE</em></u>

L = 7/(\sqrt{2}/2)

L = 14/\sqrt{2}
