Answer:

[tex]2ab^{(-6)}[/tex]

Step-by-step explanation:

Multiply exponents/group exponents

[tex]2ab^{(-2)} \times b^{(-4)}\\2ab^{-2 + -4}\\2ab^{-6}[/tex]

The answer would be 0.0078

The decimal number 0.00784 rounded off to 2 decimal places is 0.

We round off numbers to make them easier to remember and it also keeps its value approximately to the place it has been rounded off.

To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.

Given, 0.00784 and we have to round off to two significant figures means

the number will have 2 digits after the decimal place.

Now, 0.00784

= 0.00780.

= 0.0078.

= 0.0080.

= 0.008.

= 0.010.

= 0.01.

= 0.00.

= 0.

So, 0.00784 rounded off to 2 decimal places is 0.

0 is a counterexample to Kelvin's conjecture.

Firstly rewriting the expression -

x²>x + 1

Now, we will use hit and trial method to find the counterexample to Kelvin's conjecture.

We can not use first two options, because question mentions that x is not negative. So, starting our hit and trial method from 0.

We will keep the value in expression to find the result -

0²>0 + 1

0 > 1

This contradicts or opposes Kevin's statement, as 0 is not greater than 1.

Trying the second number -

5²>5 + 1

25 > 6

This is in accordance with Kevin's conjecture or conclusion, as 25 is greater than 6.

Hence, 0 is the value which is a counterexample to Kelvin's conjecture.

The expression to find the temperature at the end of the day is Morning temperature + (Change in temperature) and we get the temperature as -24 degree Fahrenheit.

Given,

The Morning temperature = 15°F

Change in temperature during day time = fall by 39 degree Fahrenheit

The temperature of the end of the day:

Morning temperature + (change in temperature)

Fall by 39° = decrease in temperature by 39° = - 39°

Therefore,

Substitute the values in the expression:

That is,

15°F + (-39°F)

15°F - 39°F

= - 24°F

Therefore, the expression to find the temperature at the end of the day is Morning temperature + (Change in temperature) and we get the temperature as -24 degree Fahrenheit.

The inverse function of  f(x) = √x + 2 would be f⁻¹(x) = x² - 2.

The domain of the function would be {x ∈ R, x ≥ −2}.

The range would be {y ∈ R, y ≥ 0}.

The inverse function returns the original value for which the output of a function was given. When it comes to functions, f and g are inverse, with f(g(x)) = g(f(x)) = x. A function that is made up of its inverse returns the original value.

Considering f(x) = y, to find the inverse function, the x and y values are switched giving the new equation of

x = √y + 2

Simplifying the above equation, we get

x - 2 = √y

x² - 2 = y

x² - 2 = y is the inverse of the function f(x)=√x+2

The domain of the function would be all x, such that x + 2 ≥ 0, or x ≥ −2.

Hence it is {x∈R, x ≥ −2}

For range, consider y =√x + 2.

Since√x+2 ≥ 0, it is obvious that y ≥ 0.

The range would be {y ∈ R, y ≥ 0}

Answer: - 2x³ - 5x² - 4x, trinomial

Step-by-step explanation:

    When writing a polynomial, the standard form is to have the terms ordered from highest power to lowest power. 3 > 2, so we will reorder them as so;

- 5x² - 2x³ - 4x ➜  - 2x³ - 5x² - 4x

    To identify the polynomial, we will look at the number of terms. This polynomial has three terms, so it is a trinomial.

- 2x³ - 5x² - 4x

[1] - 2x³

[2] - 5x²

Answer:

line J and line L are parallel so C.

The parallel line are j and l.

Hence the correct answer is c.

Given are four lines that have been graphed on the same coordinate grid.

We need to check which of these are parallel to each other.

To determine which lines are parallel to each other, we need to compare their slopes. Parallel lines have the same slope.

The general form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.

Let's identify the slopes of the given lines:

Line j: y = (2/3)x + 1/2

Slope of j: 2/3

Line k: y = (1/2)x + 2/3

Slope of k: 1/2

Line l: y = (2/3)x + 3/2

Slope of l: 2/3

Line m: y = (3/2)x + 1/2

Slope of m: 3/2

Now, let's see which lines have the same slope:

A. k & m - The slopes are different (1/2 and 3/2). These lines are not parallel.

B. k & l - The slopes are different (1/2 and 2/3). These lines are not parallel.

C. j & l - The slopes are the same (2/3). These lines are parallel.

D. j & m - The slopes are different (2/3 and 3/2). These lines are not parallel.

73° & 107°

Step-by-step explanation:

1. Those angles are supplementary, so they add up to 180 degrees.

2. (8x - 20) + (8x + 8) = 180

3. You need to add both 8x's together to make 16x. Do the same with -20 & 8. That makes -18. This is binomial addition.

4. 16x - 18 = 180

5. Add 18 to both sides

6. 16x = 198

7. Divide both sides by 16

8. x = 12.375

9. Plug in your x for both angles.
