Which sequence is generated by the function f(n + 1) = f(n) - 2 for f(1) = 10?

EleoNora [17]

Answer:

10, 8, 6, 4, 2,

Step-by-step explanation:

f(1) = 10 tells you the first term in the sequence is 10. Only one answer choice has a first term of 10.

f(n+1) = f(n) -2 tells you that each successive term is 2 less than the previous term. The same answer choice also has that characteristic.

The cost of a ticket to an amusement park is $42 per person. For groups of up to 8 people, the cost per ticket decreases by $3 f

MrRissso [65]

Answer:

Cost of each ticket per person = $42

For groups of up to 8 people, the cost per ticket decreases by $3 for each person in the group.

Marco's ticket cost $30.

This means he paid 42-30=12 dollars less.

Now when there are 8 members, the cost decreases by $3.

So, $12 will decrease, when there will be members

I hope this helps! Have an awesome day!

Alicia wanted to lose some weight, so she planned a day of exercising. She spent a total of 3 hours riding her bike and jogging.

hram777 [196]

Using the relation between velocity, distance and time, it is found that her jogging rate was of 6 mph.

<h3>What is the relation between velocity, distance and time?</h3>

Velocity is <u>distance divided by time,</u> hence:

$v = \frac{d}{t}$

Jogging, her velocity was of v, while the time was of t, for a distance of 12 miles, hence:

$v = \frac{12}{t}$

Biking, her velocity was of v + 6, while the time was of 3 - t, for a distance of 12 miles, hence:

$v + 6 = \frac{12}{3 - t}$

$v = \frac{12}{3 - t} - 6$

Then:

$\frac{12}{t} = \frac{12}{3 - t} - 6$

$\frac{12}{3 - t} - \frac{12}{t} = 6$

$\frac{12t - 36 + 12t}{t(3 - t)} = 6$

18t - 6t² = 24t - 36

6t² + 6t - 36 = 0

t² + t - 6 = 0

(t + 3)(t - 2) = 0. -> t = 2 hours.

Hence her jogging rate in mph is given as follows:

$v = \frac{12}{2} = 6$
