Write an
explicit formula for An, the nth term of the sequence 15, 8, 1, ....

Answers

Answer 1

Answer:

b(n) = 15 - 7(n - 1)

Step-by-step explanation:

15 is the y-intercept

-7 is the slope

Answer 2

Answer:

[tex]a_{n}[/tex] = 22 - 7n

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

8 - 15 = 1 - 8 = - 7

This indicates the sequence is arithmetic with explicit formula

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 15 and d = - 7 , then

[tex]a_{n}[/tex] = 15 - 7(n - 1) = 15 - 7n + 7 = 22 - 7n ← explicit formula

The equation that represents Runner #2 is t = 8.5d where t is time (in minutes) and d is distance in miles). If
Runner #2 runs 2 miles, how many minutes will it take?

Answers

Answer:

17minutes

Step-by-step explanation:

Given the equation of the time t = 8.5d took by aa runner to ru n. If the runner ran 2 miles, to calculate the time take by the runner to run two miles, we will substitute d = 2 into equation and calculate t as shown;

t = 8.5d

t = 8.5(2)

t = 17.0 minutes

Hence it will take the runner 17minutes to run 2 miles.

Runner #2's equation is an illustration of proportional equations

It will take runner #2 17 minutes to run 2 miles

Runner #2's equation is given as:

[tex]\mathbf{t = 8.5d}[/tex]

When runner #2 runs two miles, it means that:

d = 2

Substitute 2 for d in the given expression.

So, we have:

[tex]\mathbf{t = 8.5 \times 2}[/tex]

Multiply

[tex]\mathbf{t = 17}[/tex]

Hence, it will take runner #2 17 minutes to run 2 miles

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,

= 5 / 6 + 1 / 4
=   [ 5×4 + 1×6 ] / [6×4]
= 26 / 24
= 13 / 12

Find the length of the missing side. Leave your answer in simplest
radical form. *

Answers

Answer:

About 14

Step-by-step explanation:

For this you use the pythagorean theorem, which says a(a) + b(b) = c(c)

The sides that make the right angle are legs which is A and B

The other side is the hypotenuse which is C

So you set it up as

11(11) + b(b) = 18(18)

121 + b(b) = 324

324 - 121 = 203

so b(b) = 203

but 203 is b squared so you need to find the square root of 203 which is about 14.2478.

If you round that it is 14

Check

11(11) + 14(14) = 18(18)

121 + 196 = 324

317 = 324

The period of a pendulum is the time the pendulum takes to swing back and forth. The function L=0.81t^2 relates the length L in feet of a pendulum to the time t in seconds that it takes to swing back and forth. A convention center has a pendulum that is 110 feet long. Find the period.

Answers

Answer:

11.73seconds

Step-by-step explanation:

Given the expression of length L in feet of a pendulum to the time t in seconds that it takes to swing back and forth modeled as;

L = 0.81t²

Given

Length of the pendulum = 110feet

Required

Time (period)

Substitute the given value into the formula

L = 0.81t²

110 = 0.8t²

t² = 110/0.8

t² =137.5

t = √137.5

t = 11.73seconds

Hence the period is 11.73seconds
