A = {3,6,9,12,15,18,21,24,27,30,33,36}

To find the cardinal number,

just count the numbers

So, according to that,

 there are 12 numbers in this set.

So, it's clear for us that, the cardinal number of this set is 12

n (A)= 12

Find the slope of the line that goes through the given points. (0,8) and (- 4,0)

Ronch [10]

Answer:

slope = 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 8) and (x₂, y₂ ) = (- 4, 0)

m = $\frac{0-8}{-4-0}$ = $\frac{-8}{-4}$ = 2

PLEASE HELP I DONT WANNA FAIL MY QUIZ!!!

Gwar [14]

Answer: 2.5 ft.

Step-by-step explanation: We know that the wall is 10ft and each poster is 1 1/4 ft, so subtract both posters from the wall, 10-2.5 = 7.5, then divide 7.5 by 3 since we need 3 lengths, and we get 2.5ft. So for x, it would be 2.5ft.

x=2.5

Ne4ueva [31]

Length=x
Width=4x
4x•x=400 sq cm
x= 10 cm
4x= 40 cm
P=2•10cm+2•40 cm

Which choices are equivalent to the exponential expression below? check all that apply. (2/3)^3

rosijanka [135]

Answer:

B. (2/3) x (2/3) x (2/3)

C. 8/27

D. 2^3 /3^3

Step-by-step explanation:

You need to know the following property

$\LARGE \left(\frac{a}{b} \right)^c = \frac{a^c}{b^c}$

Exponent also means you're multiplying the same number for an 'n' number of times.

For example, 2^3 = 2 * 2 * 2

we multiply it by itself 3 times since 3 is the exponent.

x^y

x is the base, y is the exponent

we read it as x to the power of y

If the exponent is 2, we say it as x squared

If the exponent is 3, we say it as x cubed
