One number is 34 more than another. Their product is −289. Step 1 of 2 : Set up an equation to solve the given word problem.

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

jml angle lkj & angle mj = lm

hi im bob : l

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
