Answer:
15.71
Step-by-step explanation:
To find the radius, half the diameter because r x 2 = diameter. 5/2 = 2.5
Put in circumference formula C=2πr
c=2 x 3.14 x 2.5
c= 2 x 7.85
c=15.7
Put the value into the circle circumference formula C=2πr
Answer:none of these
Step-by-step explanation:
f(x) = mx + b
m = slope = -5
f(2) = 10 = (-5)(2) + b
b = 10 + 10 = 20
Ans. m=-5, b = 20
Answer:
Common Ratio = 2
Step-by-step explanation:
Emily started with 12 lb at start.
She will double each day
So,
2nd day she will take up weight = 12 * 2 = 24
3rd day she will take up weight = 24 * 2 = 48
and so on
This is a geometric sequence, which is a sequence where each term is found by multiplying the previous term by a constant which is known as the common ratio.
Here, we are multiplying by "2" to get the next term, so we an say the common ratio is "2".
<u>Answer: Common Ratio = 2</u>
