the circumference is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle.
Answer:
b
Step-by-step explanation:
x = 2 in this situation, so plug in 2 for x.
f(2) = (x + 1)2
f(2) = (2 + 1)2
f(2) = (3)2
f(2) = 6
f(2) = 6. That means b is the answer.
<span>w^2 + 18w + 77 = 0
breaking the middle term
</span><span>w^2 + 11w + 7w + 77 = 0
making pairs,
</span>(w^2 + 11w) + (7w<span> + 77) = 0
</span>w(w + 11) + 7(w + 11) = 0
(w+11)(w+7)=0
Hence,
the best answer is :
<span>C. (w + 7)(w + 11) </span>
Y= $6.500(1.06)^x
13000= $6.500(1.06)^x
2000=(1.06)^x
log 2000 = x log 1.06
x= log 2000/ log 1.06
