Answer:

False

Step-by-step explanation:

Let's list all the odd numbers less than 15.

13, 11, 9, 7, 5, 3, 1

Prime numbers are numbers that can only be multiplied by 1 and themselves. But, we can see, that 9 can be multiplied by 3 and 3, making it a not-prime number (sorry I don't remember the exact name for that, I'm blanking out).

The number 9 makes that statement false.

Hope I helped! ouo.

Answer:

False

Step-by-step explanation:

Consider the odd numbers less than 15

1, 3, 5, 7, 9, 11, 13

A prime number has only 2 factors, namely 1 and itself

9 has factors : 1, 3, 9 ← not Prime

The statement is therefore False

The table represents an exponential function.

kkurt [141]

Answer:

b=2/3

Step-by-step explanation:

The table is given as:

$\left|\begin{array}{c|c}x&y\\--&--\\1&9\\2&6\\3&4\\4&\dfrac83\\\\5&\dfrac{16}{9}\end{array}\right|$

The exponential function is given in the form

$y= a (b)^{x}$

where a is the initial value and b is the multiplicative rate of change

When x=1, y=9, we have:

$9= a (b)^{1}$

When x=3, y=4, we have:

$4= a (b)^{3}$

Dividing the two equations:

$\dfrac{a (b)^{3}}{a (b)^{1}} =\dfrac{4}{9} \\b^2=\dfrac{4}{9}\\b=\sqrt{\dfrac{4}{9}} \\b=\dfrac{2}{3}$

The multiplicative rate of change, b is 2/3.

Can someone please help me (Math)

Ratling [72]

Answer:

x = 11

Step-by-step explanation:

Since this is a triangle, all interior angles add up to 180 so:

57 + 73 + 3x + 17 = 180

3x + 147 = 180

3x = 180 - 147

3x = 33

x = 11
