Answer:

a=0

Step-by-step explanation:

The given expression is;

(\frac{1}{7})^{3a+3} =343^{a-1}

This implies that;

7^{-1(3a+3)} =7^{3(a-1)}

Equate the exponents;

-1(3a+3) =3(a-1)

Expand;

-3a-3 =3a-3

-3a-3a =-3+3

-6a=0

a=0

<h2>Answer:</h2>

<u>The right choice is (2) </u><u>0</u>

<h2>Step-by-step explanation:</h2>

7 ^(3a-3) = 7^(3a-3)

= -3a -3 = 3a -3

= -3a = 3a

-3a -3a = 0

-6a = 0

a= 0

If f(z)=m^z - n^z, and f(1)=2, f(2)=8. Find f(3).
Marina CMI [18]
If f(z)=m^z - n^z <span>and f(1)=2, f(2)=8
then
m -  n = 2 so m = n + 2 
m^2 - n^2 = 8

substitute </span>m = n + 2  into m^2 - n^2 = 8

so
m^2 - n^2 = 8
(n + 2)^2 - n^2 = 8
n^2 + 4n + 4 - n^2 = 8
4n = 4
  n = 1

m = n + 2 = 1 + 2 = 3

so f(z) = 3^z - 1^z

if z = 1 the f(1) = 3^1 - 1^1 = 2
if z = 2 the f(2) = 3^2 - 1^2 = 9 - 1 = 8
if z = 3 the f(3) = 3^3 - 1^2 = 27 - 1 = 26

answer
f(3) = 26

Find the base of y = b^x that contains the point (3/2, 27)
Leona [35]

Answer:

  • D) b = 9

Step-by-step explanation:

<u>Given function:</u>

  • y = b^x

The graph of it should contain the point (3/2, 27)

<u>Substitute the values and verify answer choices:</u>

A) b= 3/2

  • 27 = (3/2)^(3/2), False as the right side is irrational

B) b= 27

  • 27 = 27^(3/2), False as 27^1 ≠ 27^(3/2), because 1 ≠ 3/2

C) b= x/y

  • 27 = (x/y)^(3/2), False as is doesn't make sense

D) b= 9

  • 27 = 9^(3/2)
  • 27 = (3^2)^(3/2)
  • 27 = 3^(2*3/2)
  • 27 = 3^3
  • 27 = 27
