Answer:

y = 4 [tex](\frac{1}{2}) ^{x}[/tex]

Step-by-step explanation:

For an exponential function in the form

y = a [tex]b^{x}[/tex]

Use ordered pairs from the table to find values of a and b

Using (0, 4 ), then

4 = a [tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 ), thus

a = 4, so

y = 4 [tex]b^{x}[/tex]

Using (1, 2 ) , then

2 = 4 [tex]b^{1}[/tex] = 4b ( divide both sides by 4 )

b = [tex]\frac{1}{2}[/tex]

Thus exponential function is

y = 4 [tex](\frac{1}{2}) ^{x}[/tex]

Answer:

y = 4 (\frac{1}{2}) ^{x}

Answer:

The frequency is 3 more than expected

Step-by-step explanation:

There are 3 favourable outcomes: {2, 4, 6}

There are 6 possible outcomes: {1, 2, 3, 4, 5, 6}

probability of the number cube landing on an even number = favourable outcomes / possible outcomes = 3/6 = 1/2

If the cube is rolled 30 times, it is expected that in 1/2*30 = 15 times landed on an even number. The frequency: 18 is 3 more than expected

The answer is A; every x-value must correspond to ONE y-value only. y-values can correspond with as many x-values as they want, but if you see an x-value corresponding with more than one y-value, that's not a function.

The table represent the function because every x-value corresponds to exactly one y-value.

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

As, We can see the input values are distinct and have corresponding output.

Hence, the table represent the function because every x-value corresponds to exactly one y-value.

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

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.

Answer:

∠ FGE = 52.5°

Step-by-step explanation:

The secant- secant angle is half the difference of the measures of the intercepted arcs, that is

∠ FGE = [tex]\frac{1}{2}[/tex] (arc BD - arc FE )

           = [tex]\frac{1}{2}[/tex] × (135 - 30)°

           = [tex]\frac{1}{2}[/tex] × 105°

           = 52.5°

Answer:

B.

Step-by-step explanation:

A goes up by 1

C goes up by 8

D goes up by 5

But B increments by 2x (2 times)

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 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)
