In ΔKLM, the measure of ∠M=90°, LK = 5, KM = 3, and ML = 4. What ratio represents the cosine of ∠K?

Explanation:

M = 90 and the side opposite this is LK = 5 since "LK" doesn't have "M" anywhere in the letter sequence. The side LK is the hypotenuse. The hypotenuse is always the longest side and always opposite the right angle.

The reference angle is angle K. Opposite this angle is ML = 4. Note how ML has no mention of K. The adjacent side to angle K is KM = 3 as it's the only thing left and we have a mention of K now.

The cosine ratio is therefore...

cos(angle) = adjacent/hypotenuse

cos(K) = KM/LK

cos(K) = 3/5

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true

step-by-step explanation:

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
