Answer:
2) Exact
3) Exact
4) Exact
5) Approximation
Step-by-step explanation:
the First we need to choose two points in the graph
(0,6)=(t1,w1)
(1,7)=(t2,w2)
the variables are t and w
then we can calculate the slope

the equation of W is
where
m=1 ---> slope
b=6 ---> y-intercept

the answers are
W=t+6
slope of the function 1
the answer is the third option
Step-by-step explanation:
The above sequence is a geometric sequence
For an nth term in a geometric sequence

where
n is the number of terms
a is the first term
r is the common ratio
From the question
a = 5
r = 10/5 = 2
Therefore the explicit formula for this sequence is

Hope this helps you
You would set up a proportion. 3/8 = 6/x... cross multiply ( 3*x = 3x and 6*8 = 48) 3x = 48... divide both sides by 3 (3x/3 = x and 48/3 = 16)
So, she originally had 16 feet of ribbon.
To get a close estimate, we can round 49 up to 50 and 311 down to 300, obtaining an estimate of 50/300 = 1/6, or 0.1666... as a repeating decimal. That decimal approximation is a little less than one hundredth away from the actual decimal approximation of ≈ 0.1576
