Determine whether each of the following functions is even, odd, or neither even nor odd.
Illusion [34]

Answer:

A.) Even.

Step-by-step explanation:

If a function is an even function, then

F(-x) = f(x)

Also, if a function is an odd function, then, f(-x) = -f(x)

You are given the below function

f(x) = 1 + 3x^2 − x^4

Let x = 2

Substitute 2 for x in the function

F(x) = 1 + 3(2)^2 - (2)^4

F(x) = 1 + 3(4) - 16

F(x) = 1 + 12 - 16

F(x) = -3

Also, Substitute -2 for x in the function

F(x) = 1 + 3(-2)^2 - (-2)^4

F(x) = 1 + 3(4) - 16

F(x) = 1 + 12 - 16

F(x) = -3

Since f(-x) = f(x), we can conclude that

F(x) = 1 + 3x^2 - x^4 is even

A trapezoid has a height of 6 inches, an area of 120 square inches, and one base measuring 13 inches. Find the length of the oth
kirill [66]

Answer:

27

Step-by-step explanation:

Givens

b1 = 13

b2 = ?

h = 6

Area = 120

Formula

Area = (b1 + b2) * h/2         Multiply by 2

2Area = (b1 + b2)*h           Divide by h

2Area/h = b1 + b2              Subtract b1 from both sides

2Area/h - b1 = b2

Solution

2*120 / 6 - 13 = b2

40 - 13 = b2

b2 = 27

It is always handy to solve an equation in the form that finds the unknown on one side. It makes the solution much easier.

Which of the following is not a way to represent the solution of the inequality 2(x − 1) greater than or equal to −12?
grandymaker [24]
2(x - 1) > = -12
2x - 2 > = -12
2x > = -12 + 2
2x > = -10
x > = -10/2
x > = -5 or -5 < = x

wrong solution would be B. x less then or equal to -5....because x is greater then or equal to -5

Can you solve this? ;)

Hi there!

The answer is C.
25x + 12y + 4 \leqslant 130

The question has already revealed the following data:
x = number of tickets.
y = number of t-shirts.

We can now find the total cost function.
The cost of 1 ticket is $ 25
and therefore the total cost for all of the tickets is $25 ×
the amount of tickets, mathematically $25 × x, hence 25x.

The cost of 1 shirt is $ 12
and therefore the total cost for all of the tickets is $12 ×
the amount of shirts, mathematically $12 × y, hence 12y.

When making the total cost function, don't forget to include the service fee of $4.

Now we can conclude that the total cost function is the following:
25x + 12y + 4

Maya only has $130 and therefore the total cost must be smaller than or equal to this amount of money. The answer is C.
25x + 12y + 4 \leqslant 130
