Answer:

THE CORRECT ANSWER'S ARE A,D AND F

Step-by-step explanation:

did the test on edge .

A function is one-to-one if each horizontal line crosses the function's graph no more than once. The inverse function of F = 9/5C +32 is a one to one function.

A function is one-to-one if each horizontal line crosses the function's graph no more than once.

If the graph of a function f is known, determining whether the function is 1 -to-1 is simple. Make use of the Horizontal Line Test. If no horizontal line intersects the graph of the function f more than once, the function is one-to-one.

If f(x) = f(y)

⇒ x = y, then f is one to one.

Let the Fahrenheit temperatures be F = 9/5C +32

Subtract 32 from both sides of the above equation

F-32 = 9/5C

Multiply both sides by 5:

5(F-32) = 9C

Divide both sides by 9:

C = 5/9 (F-32)

For 27°

C = 5/9 (27-32)

simplifying the above equation, we get

⇒ C = 5/9 (-5)

⇒ C = -25/9

The value of C = -25/9.

= -2.78C°

⇒ 2dp

Yes, the inverse is a one to one function.

Polya created his famous four-step process for problem solving, which is used all over to aid people in problem solving:

Step-by-step explanation:

Polya created his famous four-step process for problem solving, which is used all over to aid people in problem solving:

Step 1: Understand the problem.

Step 2: Devise a plan (translate).

Step 3: Carry out the plan (solve).

Step 4: Look back (check and interpret).

The example using the polya's 4-steps in problem solving is created along with the answer.

Let's apply Polya's 4-step problem-solving process to the following word problem:

Problem: Lily has twice as many apples as John. Together, they have 27 apples. How many apples does each person have?

Step 1 - Understand the Problem:

To solve this problem, we need to find the number of apples that Lily and John each have. We know that Lily has twice as many apples as John, and together, they have 27 apples. We need to determine the number of apples for each person.

Step 2 - Devise a Plan:

Let's use algebra to represent the number of apples. Let's say the number of apples John has is "x." Since Lily has twice as many apples as John, the number of apples she has is "2x." We know that together, they have 27 apples, so we can set up an equation:

x + 2x = 27

Step 3 - Execute the Plan:

Now, we'll solve the equation to find the value of "x."

3x = 27

x = 27 / 3

x = 9

So, John has 9 apples. Now, we can find the number of apples Lily has:

Lily's apples = 2 * 9 = 18

Step 4 - Review the Solution:

John has 9 apples, and Lily has 18 apples. Together, they have 9 + 18 = 27 apples, which matches the information given in the problem. Therefore, the solution is correct.

Answer:

John has 9 apples, and Lily has 18 apples.

Answer:

There are 182.88 cm in 6 feet, given that 1 inch = 2.54 cm.

Step-by-step explanation:

Given that 1 inch = 2.54 cm, how many centimeters are there in 6 feet?

12 inches = 1 foot

We have 6 feet, so:

6 feet x 12 inches = 72 inches

If 1 inch is 2.54 cm, multiply by the number of inches by 2.54 to get the number of cm.

2.54 x 72 = 182.88

There are 182.88 cm in 6 feet, given that 1 inch = 2.54 cm.

If a ≤ b, then it is not true for all real numbers that a²≤ b² .

Consider a ≤ b.

Then squaring on both sides,

⇒ a²≤ b² .

But this is true only when both a and b are non-negative numbers.

For example, if we take a = 2 and b = 5, then clearly,

2² = 4 ≤ 5² = 25

Now we need to prove that this result is not true for all real numbers. So we find two real numbers a and b which does not follow this result.

Let a = -7 and b = 3

So here, a < b

Now a² = (-7)² = 49

and b² = 3² = 9

So here, a² > b².

To have an inverse function, a function must be one-to-one.

[tex]$$f^{-1[/tex](x) = x³ is the inverse of f(x) = x³

An inverse function, also known as an anti function, is a function that can be reversed into another function. Simply put, if any function " f " takes x to y, then its inverse will take y to x. The inverse function is denoted by [tex]$$f^{-1[/tex] or F-1 if the function is denoted by ' f ' or ' F '.

To find the inverse, interchange the variables and solve for y.

f−1(x)=3√x

Take the cube root of both sides of the equation to eliminate the exponent on the left side.

Replace y with [tex]$$f^{-1[/tex](x) then we get

[tex]$$f^{-1[/tex](x) = 3√x

[tex]$$f^{-1[/tex](x) = x³ is the inverse of f(x) = x³

The result of a mathematical operation, such as addition and subtraction, multiplication and division, is reversed. These are referred to as inverse operations. Typically, the inverse of a number is its reciprocal, or x - 1 = 1/x. A number and its reciprocal (inverse) product yield one.

As per coordinate geometry, a) 7.48 meters is the parameter for the path the ladybug flies between the points, including the domain. b) 1.87-meter distance does the ladybug travel per second

This is a problem from coordinate geometry and we can crack it with a few steps. First of all, the required formula to solve it is,

l = √ ( x₁ - x₂ )² + ( y₁ - y₂ )² + ( z₁ - z₂)²

where, x₁, y₁, z₁ is the coordinate of the first point and x₂, y₂, z₂ is the coordinate of the second point and l is the distance between two points.

Here x₁ = 2, y₁ = 7, z₁ = 1

and x₂ = 4, y₂ = 1, z₂ = 5

Now we have to put values in the formula,

l = √ ( 2 - 4 )² + ( 1 - 7 )² + ( 5 - 1 )²

l = √ 2² + 6² + 4²

l = √ 4 + 36 + 16

l = √ 56 = 7.48 meter

So, the ladybug flies 7.48 meters while traveling from point one to point two.

The speed taken to fly along this path is, l/t = S, where S is denoted as speed.

S = 7.48 / 4 = 1.87 meters/ second.

Answer: Use Structure multiply by a power of 10 when writing a repeating decimal as a rational number is 1/5.

Step-by-step explanation:

Define Decimal number :

A decimal is a number that consists of a whole and a fractional part. Decimal numbers lie between integers and represent numerical value for quantities that are whole plus some part of a whole.

Example: the numbers we use in everyday life are decimal numbers, because they are based on 10 digits (0,1,2,3,4,5,6,7,8 and 9). "Decimal number" is often used to mean a number that uses a decimal point followed by digits that show a value smaller than one. Example: 45.6 (forty-five point six) is a decimal number.

Define Rational numbers :

Rational number, in arithmetic, a number that can be represented as the quotient p/q of two integers such that q ≠ 0. In addition to all the fractions, the set of rational numbers includes all the integers, each of which can be written as a quotient with the integer as the numerator and 1 as the denominator.

Example : a rational number is a type of real number, which is in the form of p/q where q is not equal to zero. Any fraction with non-zero denominators is a rational number. Some of the examples of rational numbers are 1/2, 1/5, 3/4, and so on.

So, Given data,

Use Structure Why do you multiply by a power of 10 when writing a repeating decimal as a rational number?

Then we can write,

Let us assume to multiply by some number (10, 100, 1000, etc.)

Explanation:

Recall the discriminant formula is

d = b^2 - 4ac

which is the stuff found under the square root in the quadratic formula.

If d > 0, then the equation ax^2+bx+c = 0 will have two different real number roots.

So,

d > 0

b^2 - 4ac > 0

4^2 - 4(1)(k) > 0

16 - 4k > 0

16 > 4k

4k < 16

k < 16/4

k < 4 which points us to choice C

For example, if k = 0, then the equation x^2+4x+k = 0 becomes x^2+4x = 0. This has the two different roots of x = 0 and x = -4.
