circumference = 2 x PI x radius
42 = 2 x 3.14 x radius
42 = 6.28 x radius
radius = 42 / 6.28 = 6.687
= 6.69 inches
1.)
Between year 0 and year 1, we went from $50 to $55.
$55/$50 = 1.1
The price increased by 10% from year 0 to year 1.
Between year 2 and year 1, we went from $55 to $60.50.
$60.50/$55 = 1.1
The price also increased by 10% from year 1 to year 2. If we investigate this for each year, we will see that the price increases consistently by 10% every year.
The sequence can be written as an = 50·(1.1)ⁿ
2.) To determine the price in year 6, we can use the sequence formula we established already.
a6 = 50·(1.1)⁶ = $88.58
The price of the tickets in year 6 will be $88.58.
Answer:
He doesn't have enough money because the total of things he wants to buy is more than the money he has.
Step-by-step explanation:
9 + 2.65 + 1.35 + 2(1.74) must be less than or equal to 15. However all of this added together equals $16.48. This means that he doesn't have enough money.
Using the y=mx+b method and y1-y2/x1-x2
it would look like this
6-10=-4
divide
2-4=-2
and m=2 (slope)
then using y=mx+b
plug n chug
6=2(2)+b
6=4+b
b=2
thus, your equation is
y=2x+2
