Answer:

∠BFC = 50

Step-by-step explanation:

∠AFC = 90

∠AFB + ∠BFC = 90

40 + ∠BFC = 90

∠BFC = 90 - 40

∠BFC = 50

Answer: B-C

Step-by-step explanation:

I believe it is the angle of B-C becuase B-E is a strieght line which equals 180. Also EFD looks the same as AFB so it is 40. And DFC is 90 becuase of the square. So we take 180-40-90=50. And the only one that is not solved is B-C

The following numbers ARE functions:

2, 3, 6, 7, 9, 12

Step-by-step explanation:

A function is only possible if the x values have NO REPEATING NUMBER!!!

Every number that isn't mentioned above has at least 1 number in it's x-values that repeats.

Question 1 has the 8 and 4 with 2 numbers.

Question 4 the 3 repeating. (There are 2 dots over the 3)

Question 5 has numbers 1 and 5 repeating many times

Question 8 numbers 1 and 2 are repeated twice

Question 10 number 3 repeats twice

Question 11 has the 1 repeated

Answer:

Rate of change = 4,06 f/min

Step-by-step explanation:

The ascendent length 28 9/10 = 289/ 10

The time for that ascendent maneuver is total time 17 1/8 minutes - spended time in the elevation 10 minutes, then

17 1/8 = 137/8

137/8 - 10 = ( 137 - 80 ) /8 = 57/8 minutes

The rate of change in the diver´s elevation is

289 / 10 / 57/8

Rate of change = 289*8/ 57*10

Rate of change = 2312 / 570 ft/min

Rate of change = 4,06 f/min
