sadly i haven’t learned this so i can’t help you with the answers themselves but a graphing utility you could use is a graphing calculator or a graphing calculator online i know one called desmos.com just not sure if it has the intersect feature so i recommend graphing calculator

Which graph represents a proportional relationship? <br>​
Alina [70]

Answer:

If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate. For each point (x, y) on the graph, ž is equal to k, where k is the unit rate. The point (1, k) is a point on the graph.

Solve each equation, if possible. Write irrational numbers in simplest radical form. Describe the strategy you used to get your

Problem 1
Do you know what a complex number is? If you do not, you can get an answer but not one you will like much.

(3x)^2 + 27 = 0               remove the brackets. Remember to square what's inside the brackets.

9x^2 + 27 = 0                Divide both terms by 9
9x^2/9 + 27/9 = 0

x^2 + 3 =  0                  Subtract 3 from both sides.
x^2 = -3                        Take the square root from both sides.
x = sqrt(-3)                    but the square root of - 3 = 3i
x = i*sqrt(3)

Problem 2
x^ - 8x + 1 = 0
a = 1
b = - 8
c = 1

x = [- -8 +/- sqrt(b^2 - 4*a*c) ]/(2*a)     Quadratic formula
x = [ 8 +/- sqrt( (-8)^2 - 4(1*1)]/2          Substitute Givens and combine
x = [ 8 +/- sqrt( 64 - 4 )] /2                    Subtract 4
x = [ 8 +/- sqrt (60)]/2                            Break 60 into 4 * 15 
x = [ 8 +/- sqrt (4*15)]/2                         Notice 4 is a perfect square. sqrt4 = 2
x = [ 8 +/- 2*sqrt(15)] / 2                        Divide through by 2
x = 8/2 +/- sqrt (15)
x = 4 +/- sqrt(15) the twos were gone

determine if the sequence is geometric if it is find the common ratio the 8th term and the explicit formula can someone check my
mylen [45]

Answer:

You can check the answer by yourself after seeing the below answer.

Step-by-step explanation:

A sequence is geometric only if has common ratio i.e. r=\frac{a2}{a1} =\frac{a3}{a2} whiere a1,a2 and a3 are first,second and third term of the sequence respectively.

1) Common ratio r=\frac{-18}{-3}=\frac{-108}{-18}=6\\

 Explicit formula a_{n} =a_{1} .r^{n-1}

Now using the above formula, we can find 8^{th} term=-3*(6)^{8-1} =-3*6^{7}=-839808.

2) Here

\frac{a2}{a1}\neq \frac{a3}{a2}\\\frac{-2}{-4}\neq \frac{1}{-2}\\\frac{1}{2}\neq\frac{1}{-2} so this is not geometric sequence so no need to proceed further.

3) Common ratio r=\frac{15}{-3}=\frac{-75}{15}=-5\\

 Explicit formula a_{n} =a_{1} .(-5)^{n-1}

Now using the above formula, we can find 8^{th} term=-3*(-5)^{8-1} =-3*(-5)^{7}=234375.

4) Common ratio r=\frac{-6}{1}=\frac{36}{-6}=-6\\

 Explicit formula a_{n} =a_{1} .(-6)^{n-1}

Now using the above formula, we can find 8^{th} term=1*(-6)^{8-1} =1*(-6)^{7}=-279936.

5)Common ratio r=\frac{-8}{4}=\frac{16}{-8}=-2\\

 Explicit formula a_{n} =a_{1} .(-2)^{n-1}

Now using the above formula, we can find 8^{th} term=4*(-2)^{8-1} =4*(-2)^{7}=-512.

6)Common ratio r=\frac{-8}{-2}=\frac{-32}{-8}=4\\

 Explicit formula a_{n} =a_{1} .(4)^{n-1}

Now using the above formula, we can find 8^{th} term=-2*(4)^{8-1} =-2*(4)^{7}=-32768.
