Answer:
For angle B which is 50 degrees,
hypotenuse = AB =?
Adjacent = BC = 2 units......(given)
cos 50 = adjacent / hypotenuse
0.643 = 2 / AB. .....(as cos 50 = 0.643 approx)
AB * 0.643 = 2
AB = 2 / 0.643
AB = 3.11 units(approx)
Answer:
1
Step-by-step explanation:
multiply 9 and 2 which is 18 minus 15 which give u 3 divide by 3 and u get 1.
I'm pretty sure it C since line L and line M are parallel
1) 129.48 lbs : Multiply 156 by 0.17 to get 26.52, then 156 by 26.52 to get 129.48.
2) 1.96 : take 166.52 and divide that by 85. You will get 1.9590... and a lot of other crazy numbers. Round it to the nearest cent, you get 1.96.
3) 0.93 minutes : the faster time is 9.97 and the slowest is 10.9, subtract that and get 0.93.
4) 20.75 : add the prices up all together and you get 20.75
5) 18.32
6) 16.754
7) 56.44
8) I can't see the sign
9) 161.7
10) 737.49
11) 250
12) 405
13) 54.67
We have that
f²{k^6/[k^4*k^3]}^-3
step 1
f²{k^6/[k^(4+3)]}^-3---------> f²{k^6/[k^7]}^-3-------> step 1 is correct
step 2
f²{k^6/[k^7]}^-3------> f²{k^(6-7)]}^-3----> f²{k^(-1)}^-3----> step 2 is correct
step 3
f²{k^(-1)}^-3------> f²{k^[(-1)*(-3)]}-----> f²{k^(3)}
therefore
Martha made a mistake in the step 3
the answer is
step 3
f²k³
