Answer:
6 5/12 and 5 1/30
Step-by-step explanation:
Just simplify both sides of the equation.
1 3/4 + 1/6 + x = 7 1/2 ---> 1 11/12 + x =7 1/2
then subtract the 1 11/12 from both sides
x = 6 5/12
You need to use the cosine for this and this is how you do it.
Answer:
107 :)
Step-by-step explanation:
In total there are 53+8+155+17+145+10+98+2=488 physicians of aerospace medicine. 45-54 year-old males account for 145/488 of this population, so they should account for that fraction of the central angle of the circle graph also. Since there are 360 degrees in the central angle to divide up among the groups, the 45-54 year-old male group should get 145/488 x 360 which rounds to about 107 degrees.
Answer:
69 420
Step-by-step explanation:
Answer:
Explicit: -2*2^(n-1)
Recursive: 2*aₙ₋₁
Step-by-step explanation:
To write a explicit formula for this geometric sequence you follow the following formula/template
Firstnumber*commonratio^(n-1)
Seeing that the common ratio is 2 we can start plugging numbers in and get
-2*2^(n-1)
For a recursive formula we follow the following template
common ratio * the n-1 term
So we could write this as
2*aₙ₋₁
