Nana76 [90]

Answer:

$\large\boxed{a(n)=16\left(\dfrac{1}{2}\right)^{n-1}}$

Step-by-step explanation:

$a(1)=16\\\\a(2)=16:2=8\\\\a(3)=8:2=4\\\\a(4)=4:2=2\\\\a(5)=2:2=1\\\\a(n)=a_{n-1}:2=\dfrac{1}{2}a_{n-1}$

This is a geometric series with the common ratio $r=\dfrac{1}{2}$ and the first term $a_1=16$ .

An explicit formula of the n-th term of a geometric sequence:

$a_n=a_1r^{n-1}$

Substitute:

$a_n=16\left(\dfrac{1}{2}\right)^{n-1}$

What are the dimensions of the largest rectangular field that can be enclosed with 64m of wire?

Natalka [10]

Step-by-step explanation:

perimeter = 2*length + 2*width

area = length*width

perimeter = 64

Rectangular means all the corners have to be right angles.

If we say it can be a square, then...

perimeter = 4*side

64 / 4 = side

side = 16 meters

So the dimensions would be 16 m x 16 m

Ali earns a weekly salary of $475. She also earns $30 for each computer she sells. Which linear equation represents her total we

Wewaii [24]

Answer:

$y=30x+475$

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept or initial value

Let

y ----> total weekly pay

x ---> is the number of computers sold in a week

In this problem we have

$m=\$30\ per\ computer\ sold$

$b=\$475$

substitute

$y=30x+475$
