Which function is the inverse of

[tex]f(x)=x^2-16[/tex]

if the domain of f(x) is x ≥ 0?

The inverse funtion of the given function is given by

[tex]\mathbf{f(x)=\sqrt{x+16}}[/tex]

where the domain is x ≥ -16.

Given the function is,

[tex]f(x) =x^2-16[/tex]

Let, y = f(x)

[tex]y = x^2-16[/tex]

Adding 16 to both sides we get,

[tex]y + 16 = {x}^{2} - 16 + 16[/tex]

[tex] {x}^{2} = y + 16[/tex]

Now, square rooting to both sides we get, since x ≥ 0

[tex]\sqrt{x^2}=\sqrt{y+16}[/tex]

[tex]x=\sqrt{y+16}[/tex]

[tex]f^{-1}(y)=\sqrt{y+16}[/tex]

Hence substituting x in place of y,

[tex]f^{-1}(x)=\sqrt{x+16}[/tex]

Above function is the required inverse function where the domain of that is given by, x ≥ -16.

[tex]\log_48[/tex]

Step-by-step explanation:

[tex]\log_432-\log_4(4) = \log_4(\frac{32}{4} )=\log_48[/tex]

Step-by-step explanation:

By putting value of a and b in 3b-a

The value of the expression 3b - a is 19 when a= -7 and b=4 the answer is 19.

It is defined as the combination of constants and variables with mathematical operators.

We have an expression:

= 3b - a

Plug a = -7 and b = 4

= 3(4) - (-7)

= 12+7

= 19

Thus, the value of the expression 3b - a is 19 when a= -7 and b=4 the answer is 19.

The relation that represents a one-to-one function is

A. x with entries 5, 14, 7, 13, 12.

  f(x) with entries 26, 197, 50, 170, 197.

Option A is the correct answer.

We have,

A one-to-one function is a function that has one output for one input.

Now,

A.

x with entries 5, 14, 7, 13, 12.

f x) with entries 26, 197, 50, 170, 197.

This is a one-to-one function.

B.

x with entries -2, -1, 0, 1, 2.

f(x) with entries 5, 2, 1, 2, 5.

This is not a one-to-one function.

The x values -1 and 1 have the same f(x) value 2.

C.

x with entries 7.25, 7.5, 7.75, 8, 8.5.

f(x) with entries 11, 13, 15, 13, 11.

This is not a one-to-one function.

The x values 7.25 and 8.5 have the same f(x) value 11.

Thus,

Answer:

$6,722.63

Step-by-step explanation:

Now: $10,200

In 1 year: 0.92 × $10,200 = $9,384

In 2 years: 0.92 × $9,384 = $8,633.28

In 3 years: 0.92 × $8,633.28 = $7,942.6176

In 4 years: 0.92 × $7,942.6176 = $7,307.208192

In 5 years: 0.92 × $7,307.208192 = $6,722.63

Answer: $6,722.63

Answer:

$6,722.63

Step-by-step explanation:

Using this formula A=P(1-d/100)^n where

A = Amount

P = Principal

d = percent

n = number of year

A=P(1-d/100)^n

A = 10,200(1-8/100)⁵

A = 10,200(1-0.08)⁵

A = 10,200(0.92)⁵

A = 10,200(0.6591)

A= $6,722.63

The steps needed is :Translate the circles so they share a common center point, and dilate circle Y by a scale factor of 3.

Dilation is a transformation, which is used to resize the object.

As the radius of big circle is 6 then the dilation should be scale factor 3.

As well as they should share the same center.

The radius of circle y being 2, has to increase by 3 times the value to equal the radius of circle x, and hence has to dilate by a scale factor of 3 as to match circle x,

Answer:

Brand A is the best buy.

Step-by-step explanation:

Brand A has a pack of 28 pencils for 5.29 dollars. This means that the unit cost of one pencil in Brand A would be 5.29/28 = 0.2$ per pencil rounded up to the nearest tenth.Brand B has a pack of 48 pencils for 8.47 dollars. This means that the unit cost of one pencil in Brand B would be 8.47/48 = $0.8 per pencil rounded up to the nearest tenth.Since $0.2 is lesser than $0.8, it means that Brand A is the best buy.

Based on the calculations, the average selling price for these properties is equal to $127,865.

Mathematically, the average selling price for these properties would be calculated by using the following formula:

Average price = [F(x)]/n

Note: The total number of properties is equal to 5.

Substituting the given parameters into the formula, we have;

Average price = [118,450 + 126,500 + 128,000 + 130,425 + 135,950]/5

Average price = 639,325/5

Average price = $127,865.

Answer:

(0, 0)

Step-by-step explanation:

Ok so you have the equation: [tex]y = log_2{(x+2)}-1[/tex]. To find the zero you simply set the y equal to zero and then solve for x

[tex]0 = log_2{(x+2)}-1[/tex]

Add 1 to both sides

[tex]1 = log_2{x+2}[/tex]

Rewrite the equation in exponential form:

[tex]2^1=x+2[/tex]

Subtract 2 from both sides

[tex]0 = x[/tex]

So the zero of the function is at the origin (0, 0)

So let start with 1/4 simplest form of that would be 9/4 and for 11/24 simplest would be just that so now we got 11/24 - 9/4 = 1/72

Step-by-step explanation:

11/24

4/9

now we do 11 x 9 equals 99 so now 4 x 24 = 96

now we take the two new denominators2 24 and 9

and we do 24 x 9 = 216 so now we got

99/216

96/216

now 99 - 96 is 3 so we got a new fraction

3/216 now we just simplify that  so we get 1/72

Answer: [tex]230^{\circ[/tex]

Step-by-step explanation:

For convenience, I labeled some points as shown in the attached picture.

Also, I assume [tex]\overline{AB}[/tex] and [tex]\overline{BC}[/tex] are tangents to the circle.

Therefore, we know [tex]\triangle ABO \cong \triangle CBO[/tex] by HL.

Thus, by CPCTC,

[tex]\angle AOB \cong \angle BOC \implies m\angle BOC=65^{\circ}\\\\\implies m\angle AOC=130^{\circ}[/tex]

This means the measure of minor arc AC is [tex]130^{\circ}[/tex], and thus [tex]b=360^{\circ}-130^{\circ}=\boxed{230^{\circ}}[/tex]

Answer:

28

Step-by-step explanation:

1 dog = 4 legs, 2 dogs = 8 legs

1 horse = 4 legs, 4 horses = 16 legs

1 giraffe = 4 legs.

So we need to add "2 dogs = 8 legs", "4 horses = 16 legs", and 1 giraffe = 4 legs.

(8 + 16 + 4)

We get the final answer: 28
