Answer:
1.1.1 sin(241°) = -√t
1.1.2 cos(61°) = √(1 -t)
Step-by-step explanation:
<u>Given</u>:
sin(61°) = √t
<u>Find</u>:
1.1.1 sin(241°)
1.1.2 cos(61°)
<u>Solution</u>:
1.1.1 sin(180° +x) = -sin(x)
sin(241°) = -sin(61°) = -√t
__
1.1.2 cos(x) = √(1-sin²(x))
cos(61°) = √(1 -(√t)²) = √(1 -t)
If you put 5 which means its 2 1/2 ( I think) Because two 1/2 makes one.
Answer:
The number of trees at the begging of the 4-year period was 2560.
Step-by-step explanation:
Let’s say that x is number of trees at the begging of the first year, we know that for four years the number of trees were incised by 1/4 of the number of trees of the preceding year, so at the end of the first year the number of trees was
, and for the next three years we have that
Start End
Second year
-------------- 
Third year
-------------
Fourth year
--------------
So the formula to calculate the number of trees in the fourth year is
we know that all of the trees thrived and there were 6250 at the end of 4 year period, then
⇒
Therefore the number of trees at the begging of the 4-year period was 2560.
It’s blurry I can barely see it.
