How can you check if a point is an element of the function?

Answers

Answer 1

Answer:

Graph or make a table of the function.

Step-by-step explanation:

When you graph the function just look on the graph to see that point is part of your function. Same would go for the table. Just look and see if your numbers match.

A rectangular prism has a length of 9 in., a width of 4 in., and a height of 1 1/2in. The prism is filled with cubes that have edge lengths of 1/2 in. How many cubes are needed to fill the rectangular prism?

Answers

Hey there! :)

Answer:

432 cubes.

Step-by-step explanation:

Volume of rectangular prism: V = l × w × h

V = 9 × 4 × 1.5

V = 54 in³

Volume of cubes: V = s³

V = 1/2³

V = 1/8 in³

Set up an equation to solve for the # of cubes needed (x):

54 = 1/8x

Divide both sides by 1/8:

54 × 8/1 = x

x = 432 cubes.

Answers

Hey there!

Answer:

2nd choice, The graph of g(x) is the graph of f(x) reflected in the x-axis, expanded vertically by a factor of 5, and translated 8 unit(s) down.

Step-by-step explanation:

Recall that the transformation form of a logarithmic function is:

y = ±alog(b(x-h))+k

Given g(x) = -5logx-8:

Negative in front of equation: reflection over the x-axis

'a' value of 5: expanded vertically by a factor of 5

'k' value of -8: translated 8 unit(s) down.

b) 12400 cm³

Step-by-step explanation:

1 cm³ = 1 mL

1000 mL = 1 L

a)

2800 cm³ × (1 mL)/(1 cm³) × (1 L)/(1000 mL) = 2.8 L

b)

12.4 L × (1000 mL)/(1 L) × (1 cm³)/(1 mL) = 12400 cm³

Answer:

150 steps

this is a sketch of the curve with equation y=f(x) the vertex of the curve is at (2,-3)

Answers

Answer:

see explanation

Step-by-step explanation:

(a)

Given f(x) then f(x) + c represents a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

f(x) + 5 represents a shift up of 5 units, thus

(2, - 3 ) → (2, - 3 + 5 ) → (2, 2 )

(b)

Given f(x) then - f(x) represents a reflection of f(x) in the x- axis

Under a reflection in the x- axis

a point (x, y ) → (x, - y ), thus

(2, - 3 ) → (2, 3 )

The vertex of the given curve is the minimum point on the curve.

The vertex of f(x) + 5 is (2,2)The vertex of -f(x) is (2,3)

The vertex is given as:

[tex]\mathbf{(x,y) = (2,-3)}[/tex]

(a) The vertex of f(x) + 5

The rule of the given transformation is:

[tex]\mathbf{(x,y) \to (x,y + 5)}[/tex]

So, we have:

[tex]\mathbf{(x,y) \to (2,-3 + 5)}[/tex]

[tex]\mathbf{(x,y) \to (2,2)}[/tex]

Hence, the vertex of f(x) + 5 is (2,2)

(b) The vertex of -f(x)

The rule of the given transformation is:

[tex]\mathbf{(x,y) \to (x,-y)}[/tex]

So, we have:

[tex]\mathbf{(x,y) \to (2,-(-3))}[/tex]

[tex]\mathbf{(x,y) \to (2,3)}[/tex]

Hence, the vertex of -f(x) is (2,3)

if she countinues to walk at that rate it will take her 24 minutes to walk the 32 blocks

Step-by-step explanation:

i took the 12 blocks every 9 minutes and counted for a total of 36 blocks which would take 27 minutes then since we want to know how long it would take for her to walk 32 blocks I found how long it would take her to walk 4 blocks which is 3 minutes (12/3 = 4 9/3 =3) and i subtracted those 3 minutes from the 36 block walk giving you 24 minutes for 32 blocks

Answer:

f(x + 5/4) --> f(x) is translated 5/4 units left.

f(x) - 5/4 --> f(x) is translated 5/4 units down.

Step-by-step explanation:

Recall that a linear equation in transformations form is:

f(x) = ±a(b(x-h))+k

In this instance:

f(x + 5/4) the 'h' value is -5/4, meaning the graph is translated 5/4 units left.

f(x) - 5/4 has a 'k' value of -5/4, so the graph is translated 5/4 units down.
