Answer: x=-20
Step-by-step explanation:
Isolate the variable(x) by dividing each side by factors (50) that do not contain the variable.
Answer:
3
Step-by-step explanation:
the mean is 103, as a result you must find the distance.
from 100 to 103 is 3
from 194 to 103 is 1
from 107 to 103 is 4
Then find the mean again youll get 18/6 which is 3
We have that
<span>tan(theta)sin(theta)+cos(theta)=sec(theta)
</span><span>[sin(theta)/cos(theta)] sin(theta)+cos(theta)=sec(theta)
</span>[sin²<span>(theta)/cos(theta)]+cos(theta)=sec(theta)
</span><span>the next step in this proof
is </span>write cos(theta)=cos²<span>(theta)/cos(theta) to find a common denominator
so
</span>[sin²(theta)/cos(theta)]+[cos²(theta)/cos(theta)]=sec(theta)<span>
</span>{[sin²(theta)+cos²(theta)]/cos(theta)}=sec(theta)<span>
remember that
</span>sin²(theta)+cos²(theta)=1
{[sin²(theta)+cos²(theta)]/cos(theta)}------------> 1/cos(theta)
and
1/cos(theta)=sec(theta)-------------> is ok
the answer is the option <span>B.)
He should write cos(theta)=cos^2(theta)/cos(theta) to find a common denominator.</span>
80 divided by 15 Is =5.333333 which I don’t know how to round it but it would be around 5 at least
