The first term of a geometric sequence is 32, and the 5th term of the sequence is 818 .

sammy [17]

Answer:

$32,24,18,\frac{27}{2} ,\frac{81}{8}$

Step-by-step explanation:

Let x, y , and z be the numbers.

Then the geometric sequence is $32,x,y,z,\frac{81}{8}$

Recall that term of a geometric sequence are generally in the form:

$a,ar,ar^2,ar^3,ar^4$

This implies that:

a=32 and $ar^4=\frac{81}{8}$

Substitute a=32 and solve for r.

$32r^3=\frac{81}{8}$

$r^4=\frac{81}{256}$

Take the fourth root to get:

$r=\sqrt[4]{\frac{81}{256} }$

$r=\frac{3}{4}$

Therefore $x=32*\frac{3}{4} =24$

$y=24*\frac{3}{4} =18$

$z=18*\frac{3}{4} =\frac{27}{2}$

Find the area of a square with a side measure of 3x − 6 feet.

Wittaler [7]

Area of a square: s^2

Because we know the length of one side, we can multiply it by itself to find the area.

(3x - 6)(3x - 6)

9x^2 - 18x - 18x + 36

Combine like terms.

9x^2 - 36x + 36

<h3>The correct answer is A, or the first answer. </h3>

a taxi service charges an initial fee of $5 plus $1.80 per mile. How many miles can you travel for $12

user100 [1]

First you need to write an equation or an inequality.

5+1.80x<=12
the x here is how many miles you are paying for, now you just solve for x.

5+1.80x<=12
-5 -5

1.80x<=7
/1.80 /1.80
x<=3.8

you can travel only three whole miles, you do not have enough money to go four full miles.
