Answer:

5, 15, 45 and 135

Step-by-step explanation:

Given the recursive function;

an = 3a(n-1)

If a1 = 5

a2 = 3a1

a2 = 3(5)

a2 = 15

For a3;

a3 = 3a2

a3 = 3(15)

a3 = 45

For a4;

a4 = 3a3

a4 = 3(45)

a4 = 135

Hence the first four terms are 5, 15, 45 and 135

The table of ordered pairs (x,y) gives an exponential function.
Andreyy89

The equation for the exponential function containing the points (0, 8) and (1, 32) is y = 8(4)ˣ

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depend on any other variable for its value while a dependent variable is a variable that depends on other variable.

An exponential function is in the form:

y = abˣ

Where a is the initial value and b is the multiplication factor.

At point (0, 8):

8 = ab⁰

a = 8

At point (1, 32):

32 = 8b

b = 4

The equation for the exponential function containing the points (0, 8) and (1, 32) is y = 8(4)ˣ

the product of five consecutive odd integers is 945 what is the greatest possible value of any of these integers
Troyanec [42]
If 945 is the product of 5 CONSECUTIVE ODD  numbers, let's find the prime factors of 945:

945 = 5 x 7 x 27 , but we need 5 odd numbers:

945= 5 x 7 x ( 3 x 9 ) we still need one factor. This factor cannot be but 1

945 = 1 x 3 x 5 x 7 x 9 = 945 and the greatest value of these integers is 9

Solve for the value of k.
OLEGan [10]

Answer:

The value of K is 5

Step-by-step explanation:

I reversed it.

The tiny squares means 90⁰, so 90+49=139

All of these angles add up to 180⁰

So 180-139=41

The k equation equals 41⁰, so reverse it to find answer

41-1=40

40÷8=5
