Isaac keeps track of the miles per gallon his car gets per week. He has accumulated the following data:

ipn [44]

we know that

A <u>geometric sequence</u> is a sequence of numbers in which the ratio between consecutive terms is constant

Let

$a1=24 \ a2=24.48\ a3=24.97\ a4=25.47$

$\frac{a2}{a1} = \frac{24.48}{24}= 1.02$

$a2=a1*1.02$

$\frac{a3}{a2} = \frac{24.97}{24.48}= 1.02$

$a3=a2*1.02$

$\frac{a4}{a3} = \frac{25.47}{24.97}= 1.02$

$a4=a3*1.02$

therefore

The common ratio is equal to $1.02$

<u>the answer is</u>

The common ratio is 1.02

Use the Pythagorean Theorem to find the hypotenuse (c)

kirza4 [7]

Pythagorean theorem= a^2 + b^2= c^2

The sides are a & b and the hypotenuse is c.

a= 9ft
b= 12ft
c= ?

a^2 + b^2= c^2
(9)^2 + (12)^2= c^2
81 + 144= c^2
225= c^2
take the square root of 225 and c
15= c

ANSWER: c= 15 feet

Hope this helps! :)

An identification code is to consist of 3 letters followed by 3 digits. Determine the following

Free_Kalibri [48]

Answer:

3 letters can be arranged in 26*25*24 = 15600 ways

3 digits can be arranged in 10 * 9 * 8 = 720 ways

So the total number is 15600 * 720 = 11,232,000

So I agree with the number that you obtained
