Answer:
1/12 foot
Step-by-step explanation:
2x+9y=-30 subtract 2x from both sides
9y=-2x-30 divide both sides by 9
y=-2x/9-30/9
So the slope of the reference line is -2/9. For a line to be perpendicular to this line their slopes must be negative reciprocals of one another, mathematically:
m1*m2=-1 and in this case:
-2m/9=-1
m=9/2
m=4.5, so far we have:
y=4.5x+b, using point (-8, 0) we can solve for b
0=4.5(-8)+b
0=-36+b
36=b, so our line is:
y=4.5x+36
<span>p ← 1
s ← 0
for i is in {1, 2, 3, 4}
do p ← p · 3
s ← s + p
n = 1 => first iteration
p = 1 * 3 = 3
s = 0 + 3 = 3
number of multiplications ---> 1
n = 2
p = 3 * 3 = 9
s = 3 + 9 = 12
number of multiplications ----> 1 + 1 = 2
n = 3
p = 9 * 3 = 27
s = 12 + 27 = 39
number o multiplications --> 2 + 1 = 3
n = 4
p = 27 * 7 = 81
s = 39 + 81 = 120
final number of multiplications -----> 3 + 1 = 4
final value of s
s = 120
Answer: number of mujltiplications: 4
final value of s: s = 120.
