Explicit equation for 5,10,20,40
eduard

Answer:

see explanation

Step-by-step explanation:

These are the terms of a geometric sequence with n th term

a_{n} = a(r)^{n-1}

Where a is the first term and r the common ratio

r = \frac{10}{5} = \frac{20}{10} = \frac{40}{20} = 2

and a = 5, hence explicit equation is

a_{n} = 5(2)^{n-1}

mina [271]

Answer:

440 seagulls

Step-by-step explanation:

Total number of seagulls in flock = Number of seagulls have banded / Percentage of seagulls have banded

Total number of seagulls in flock = 22 / 5%

Total number of seagulls in flock = 22 / 0.05

Total number of seagulls in flock = 440 seagulls

A phone company charges $.25 for the first minute of a long distance call and $.07 for each addition minute. write an equation t
Mamont248 [21]

The cost C of a long distance call as a function of the length t is C(t) = 0.25 + 0.07t and the number of minutes is 25 minutes

<h3>What are linear equations?</h3>

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

<h3>How to determine the solution to the system?</h3>

A system of linear equations is a collection of at least two linear equations.

In this case, the given parameters are:

Charge for first minute = $.25

Rate for additional minute = $.07 per minute

Let the number of minutes be t and the total cost be C(t)

So, we have:

C(t) = Charge for first minute + Rate for additional minute * x

This gives

C(t) = 0.25 + 0.07t

When the total cost is $2, the equation becomes

0.25 + 0.07t = 2

Subtract 0.25 from both sides

0.07t = 1.75

Divide both sides by 0.07

t = 1.75/0.07

Evaluate the quotient

t = 25

Hence, the number of minutes is 25 minutes
