Juan ran the 200 meters in 26.47 seconds, Scott ran it in 26.82 seconds, Kyrah ran it in 26.9 seconds, and Beth ran it in 30.07

Natalka [10]

Answer:

Juan did.

Step-by-step explanation:

the two fastest speeds are 26.47 and 26.9 seconds. In order to be able to properly work with that, you need to add a 0 to 26.9 so that it turns into 26.47 and 26.90 seconds. If you were yo subtract those, you would have:

26.90-26.47= 0.43

Therefore, 26.47 seconds is faster than 26.9 seconds.

The law of Cosines Is......

iogann1982 [59]

Answer: $\Large\boxed{C.~21}$

Step-by-step explanation:

The goal of the question

Find the value of 2abcosC

Given information

a = 4

b = 3

c = 2

Given formula (Law of Cosine)

$c^2=a^2+b^2-2abcosC$

Substitute values into the formula (Leave 2abcosC as it is)

$(2)^2=(4)^2+(3)^2-2abcosC$

Simplify the exponents

$4=16+9-2abcosC$

Simplify by addition

$4=25-2abcosC$

Add 2abcosC on both sides

$4+2abcosC=25-2abcosC+2abcosC$

$4+2abcosC=25$

Subtract 4 on both sides

$4 + 2abcosC-4=25-4$

$\Large\boxed{2abcosC=21}$

Hope this helps!! :)
