<span>The arc length by definition is given by:</span>
<span> S = R * theta</span>
<span> Where,</span>
<span> R: radio</span>
<span> Theta: central angle</span>
<span> Substituting values we have:</span>
<span> S = 10 * (3/2) pi</span>
<span> Rewriting we have:</span>
<span> S = 5 * (3) pi</span>
<span> S = 15pi</span>
<span> Answer:</span>
<span> The arc length is:</span>
<span> <span>S = 15pi</span></span>
For this case we must evaluate the following expression:
14 + (- 8) ÷ 2 * -3
According to the method of algebraic resolution, called PEMDAS, the divisions and multiplications must be made from left to right, before the addition and subtraction, then:
14 + (- 4) * - 3 =
We eliminate the parenthesis keeping in mind that 
Equal signs are added and the same sign is placed:
Answer:
26
5)Substituting any of the following equations; i chose bottom into top:
-2x+5=x+2
=>-3x=-3
=>x=1
Sub the x in any of the eqs to find y so
Y=1+2
=>Y=3
ANS: (1,3)
6) substituting the top equation into the bottom one:
3x+2x+4=9
=>5x=13
=>x=13/5 or 2.6
Sub the x in any of the eqs to find the y so
Y=5.2+4
=>y=9.2
ANS: (2.6, 9.2)
Answer:
l
Step-by-step explanation:
Answer:
f(12) = - 20
Step-by-step explanation:
To evaluate f(12), substitute x = 12 into f(x), that is
f(12) = - 2(12) + 4 = - 24 + 4 = - 20
