the last option. would be correct

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,

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

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

This is a one-to-one function.

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.

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,

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.

Which point corresponds to the real zero of the graph of y = log2 (x + 2) - 1?

Answers

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)

Find the value of b.

Answers

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.

[tex]\overline{BO} \cong \overline{BO}[/tex] (reflexive property)[tex]\overline{AB} \cong \overline{BC}[/tex] (tangents drawn from a common external point are congruent)[tex]\angle BAO \cong \angle BCO[/tex] (right angles are congruent)

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]

You are buying a used car which costs $10,200. You plan to sell the car after keeping it for 5 years. Research shows that this car will lose value at a rate of 8% per year. How much will the car be worth after 5 years?

Answers

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

What is a Ratio?

A ratio shows us the number of times a number contains another number.

The ratio of fertilizer to soil is,

Fertilizer/Soil = 12 ounces / 10 pounds

The amount of fertilizer that the farmer need to mix for 120 pounds of soil is,

Fertilizer/120 pounds = 12 ounces / 10 pounds

Fertilizer = (12 ounces × 120 pounds)/10pounds

Fertilizer = 144 ounces

Which function is the inverse of if the domain of f(x) is x ≥ 0?

Answers

The question was incomplete. Please find full content below.

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.

Linda needs to buy pencils brands has a pack of 28 pencils for 5.29 brand b has a pack of 48 pencils for 8.47 find the unit price for each brand.

Answers

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.

Answers

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

How to determine the average selling price?

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
