Which sequence is modeled by the graph below?

Ipatiy [6.2K]

First, we inspect what type of sequence is the order of the coordinates:
a2 = 1
a3 = 2
a4 = 4

Getting the difference,
a3 - a2 = 1
a4 - a3 = 2

The differences are not equal; hence, the sequence is not arithmetic.

Getting the ratio:
a3/a2 = 2
a4/a3 = 2

The common ratio is 2. Using the general form for a geometric series:
an = a1 r^(n-1)
If n = 2
1 = a1 (2)^(2-1)
a1 = 1/2

So,
an = (1/2) (2)^(n-1)

The answer is the first option.

Courtney must earn at least $150 to pay for broken window. She earns $10 for every car she washes.

valkas [14]

Answer:

10c ≥ 150

At least 15 cars (or c ≥ 15)

Step-by-step explanation:

If she gets $10 for every car she washes a car then 10c is the rate of her gaining money and she needs at least (greater than or equal to) $150.

This equation can be used to express the situation:

10c ≥ 150

To solve you divide the 10 from both sides of the inequality to get.

c ≥ 15

Austin is riding his dirt bike at a speed of 350 feet per minute. How many yards would he have traveled in 2.5 hours? (HINT: 3 f

Harrizon [31]

Answer:

17,500 yards

Step-by-step explanation:

Speed of Austin's bike = 350 ft per minute

Given 3 feet in 1 yard

Now converting speed from ft/min to yard per minute

3 feet equal 1 yard (dividing both side by 3)

1 feet equals 1/3 yards

350 ft equals 350*1/3 yards

350 ft equals 350/3 yards

speed of bike in yards per minute = 350/3 yards per minute

______________________________________

Time for which bike traveled = 2.5 hour

one hour has 60 minutes

2.5 hour has 60*2.5 minutes

2.5 hour has 150 minutes

Time for which bike traveled in minutes = 150 minutes

________________________________________

formula for distance = speed * time

substituting value of speed and time in above equation we have

distance = 350/3 * 150 = 17,500 yards

Distance traveled by Austin's bike in 2.5 hours is 17,500 yards.
