Answer:
2.5+7.5+-10n+-20
Step-by-step explanation:
Multiply everything on the inside by the number on the outside and put it together with addition signs.
-2.5(-3+4n+8)
-2.5*-3=7.5
-2.5(7.5+4n+8)
-2.5*4= -10
-2.5(7.5+-10n+8)
-2.5*8=-20
-2.5+7.5+-10n+-20
Answer:
0.04 inces
Step-by-step explanation:
For the answer to the question above, asking to g<span>raph the six terms of a finite series where a1 = 5 and r = 1.25.
I'll provide the answer with the solutions below.
</span>a1 = 5
<span>a2 = 5*r = 5*(5/4) = 25/4 </span>
<span>a3 = 5*r² = 5*(5/4)² = 125/16 </span>
<span>a4 = 5*r³ = 5*(5/4)³ = 625/256 </span>
<span>a5 = 5*r⁴ = 5*(5/4)⁴ = 3125/1024
</span>I hope this helps
Answer:
Sine, cosine and tangent formulas are used in RIGHT triangles. So you have one 90 degree angle and two acute angles that add up to 90 degrees (they are complimentary). So the cosine of one angle would be the same as the sine of the compliment to that angle... and vice versa. To answer this question, sin 81 = cos 9, since 81 and 9 are the two acute angles of the triangle and they both add up to 90 degrees. "Cos 9" is the answer when you wish to write "sin 81" in terms of "cosine."
