Answer:

The function is even because f(x) = f(−x).

Step-by-step explanation:

we know that

An even function is one for which  

f (−x)=f(x) for all x in its domain.

An odd function is one for which  

f( −x) =−f(x) for all x in its domain

In this problem we have

f(x)=3x^{4}

so

f(-x)=3(-x)^{4}=3x^{4}

therefore

f (x)=f(-x) for all x in its domain.

Answer:

Option A) The function is even because f(x) = f(−x).

Step-by-step explanation:

We are given the following in the question:

f(x) = 3x^4

We have to check whether the given function is odd or even.

Even function:

  • f(-x) = f(x)

Odd function:

  • f(-x) = -f(x)

To check, we evaluate f(-x)

f(x) = 3x^4\\f(-x) = 3(-x)^4 = 3(-1)^4(x)^4 = 3x^4 = f(x)

Thus, the given function is even.

ms. lorenz needs to rent a car for 3 days. she can choose from two plans. plan a costs $60 per day. plan b costs $30 per day plu
maw [93]

Answer:

distance driven < 300 miles.

Step-by-step explanation:

Plan A

She needs the car for 3 days.

1 day costs 60 dollars

3 days cost 60*3 = 180 So this is the maximum amount that she can spend

Plan B

She still needs the car for 3 days

1 day costs 20 dollars of the car does not move

3 days costs 3*20 = 60 dollars.

60 + 0.4m < 180                Subtract 60

0.4m < 180 - 60

0.4m < 120                        Divide by 0.4

m < 120/ 0.4

m < 300  

Answer

so she should drive less than 300 miles.

A fish tank has a base area of 45cm2 and is filled with water to a depth of 12cm.If the height of the tank is 25cm, how much wat
stepladder [879]

Answer:

Step-by-step explanation:

v = 45 * 12

v = 540cm³

To fill the tank,

v = 45 * 25

v = 1,125cm³

I'm not quite sure what the exact question is so i'll answer both;

1.) The volume of water required to fill the tank from empty = 1,125cm³

2.) The volume of water required to fill the tank from it's current level is

1,125cm³ - 540cm³ = 585cm³

On a coordinate grid, AB has an end point B at (24, 16). The midpoint of AB is P(4, -3). What is the y-coordinate of Point A?
inysia [295]

The y-coordinate of point A is -22

Step-by-step explanation:

Given

B = (24,16)

P = (4,-3)

The formula for mid-point of AB will be given by:

P = (\frac{x_A+x_B}{2} , \frac{y_A+y_B}{2})

As we already know the y-coordinate of midpoint

We can put the formula's y coordinate equal to the given value

\frac{y_A+y_B}{2} = -3\\\frac{y_A + 16}{2 } = -3\\y_A+16 = -3 * 2\\y_A +16 = -6\\y_A = -6-16\\y_A = -22

Hence,

The y-coordinate of point A is -22
