= 4s - 21
First, simplify
to
/ Your problem should look like:
Second, multiply both sides by 2. / Your problem should look like:
Third, subtract 8s from both sides. / Your problem should look like:
Fourth, simplify s - 8s to -7s. / Your problem should look like:
Fifth, divide both sides by -7. / Your problem should look like:
Sixth, simplify
to
/ Your problem should look like:
Seventh, simplify
to 6. / Your problem should look like:
Answer:
s = 6
Answer:
Step-by-step explanation:
i think it is 2
Answer:
does not exist
Step-by-step explanation:
Inserting 2 to both formulas, you get different results. In that cases, a limit does not exist
We know that
sin²x+cos²x=1
so
clear cos x
cos x=(+/-)√[1-sin²x]
in this problem
<span>Angle 0 is in quadrant 1 -----> cos o and sin o are positive
</span>sin o=2/5
cos x=√[1-(2/5)²]----> cos o=√[1-4/25]----> cos o=√[21/25]---> cos o=√21/5
the answer is
cos o=√21/5
17 tens can be said as 17 x 10
So 17 x 10 is 170
170 is in standard form
