For easier, let's say x represents a pack of 10 and y represents a pack of 30

we can start with 2 of the 30's
2y=60
we can replace one of the 30's with 3 of the 10's
y+3x=60

and finally we can use all 10's
6x=60

there are only 3 ways

Three sets have 5, 10, 15 elements, respectively. How many elements can their union and intersection have?​
Degger [83]

Answer:

Union = 15

Step-by-step explanation:

Given

n(A) = 5; n(B) = 10; n(C) = 15

Solving (a): Possible union elements

This is the represented by element with the largest number of the sets

i.e.

Union = 15

Solving (b): Possible intersection elements

This is the represented by element with the least number of the sets

i.e.

Intersection = 5

Determine the domain and range of (g ○ f)(x) if f of x is equal to 9 over the quantity x squared minus 9 end quantity and g(x) =
Bezzdna [24]

The domain is all real numbers except -6 and 0. Hence, domain D: {x ∈ ℝ| x ≠ –6, 0}

Hence the range is all real numbers except -3 and 3. Hence, range R: (–∞, –3) ∪ (3, ∞)

Given the following functions:

f(x)=\frac{9}{x^2-9}\\g(x)=x+3

First we need to get the composite function f(g(x))

f(g(x)) = f(x+3)\\f(x+3)=\frac{9}{(x+3)^2-9} \\f(x+3)=\frac{9}{x^2+6x+9-9} \\f(x+3)=\frac{9}{x^2+6x} \\

Get the domain

The domain the values of x for which the function exists. The function cannot exists at when x = -6 and x = 0

  • Hence the domain is all real numbers except -6 and 0. Hence, domain D: {x ∈ ℝ| x ≠ –6, 0}

The range is the value of y for which the function exists. The function cannot exists at when x = -6 and x = 0

  • Hence the range is all real numbers except -3 and 3. Hence, range R: (–∞, –3) ∪ (3, ∞)

3. The graph of a polynomial function is
ra1l [238]

9514 1404 393

Answer:

  A. The degree of the polynomial is even.

Step-by-step explanation:

The end behavior is the same in both directions (for -x and for +x, y → ∞), so the degree of the polynomial is even.

__

The constant term is the y-intercept. It is not an integer, so cannot be said to be even or odd.

PLEASE HELP!!!!!!!!!!!
garik1379 [7]

First convert the hours to minutes

1hr = 60mins

15hrs = 15 \times 60mins

= 900minutes

now change the 900mins to seconds

as

1mins = 60sec

900mins = 900 \times 60sec
