Find the Incomplete table in attached file
Given:
A car travels 55 miles per hour for 2 hours.
So the speed of the car 55 miles per hour is constant for 2 hours.
Using speed formula.
Second row.
From the second row of the table and speed is constant
, so we need to find only distance.
Third row.
From the third row of the table and speed is constant
, so we need to find only distance.
Fourth row.
From the fourth row of the table and speed is constant
, so we need to find time.
Therefore we complete the table from the above calculation.
a.
In order to find the common ratio, we just need to divide a term by the term that comes before it.
So using the terms 20 and -5, we have:
b.
The recursive rule can be found with the formula:
Where an is the nth term and q is the ratio. So we have:
c.
The explicit rule can be written as:
Where an is the nth term, a1 is the first term and q is the ratio. So:
Answer:
x ≈ 20.42, y ≈ 11.71
Step-by-step explanation:
Using the cosine ratio on the right triangle on the right, that is
cos20° = =
Multiply both sides by y
y × cos20° = 11 ( divide both sides by cos20° )
y = ≈ 11.71
Using the sine ratio on the right triangle on the left, that is
sin35° = =
=
Multiply both sides by x
x × sin35° = 11.71 ( divide both sides by sin35° )
x = ≈ 20.42
