Will mark you brailiest PLZ ANSWER! Evaluate the expression. 2 to the power of 4 · 3²

144

Step-by-step explanation:

You need to know the Order of Operations. First you do 2 to the power of 4 (because it's the E in PEMDAS) which is 2*2*2*2 which equals 4, 8, 16, then you would do three squared which is 3*3 which equals 9. Multiply (M in PEMDAS) 16 by 9 which would come out to 144 or how I would multiply those two numbers is 9*10 + 9*6 or 90 + 54 with a final answer of 144.

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

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
