Which expresses 9x^2y^2 as a perfect square?

Answer:

  B.  x ≥ 6

Step-by-step explanation:

The value √(x-6) is only defined for x ≥ 6, where the argument of the square root function is non-negative.

Similarly, the value √(x+3) is only defined for x ≥ -3.

The product can only be computed where both functions are defined:

  (x ≥ 6) ∩ (x ≥ -3) = x ≥ 6

Answer:

circumference of a circle = [tex]\pi[/tex]d

Step-by-step explanation:

circumference of a circle = 2[tex]\pi[/tex]r

where r = radius

diameter of a circle d = 2r

where r = radius

Therefore, circumference of a circle = [tex]\pi[/tex]d

Answer:

5 miles = $8

8 miles = $11

20 miles = $23

Step-by-step explanation:

If admission is 3 dollars, then we already know that is the minimum we have to pay. The rest of the money we spend on the trolley depends on how many miles we travel on it. If each mile is 1 dollar, then we can use a variable to represent the number of miles since there are numerous possible answers.

The basic equation to represent the scenario is:

3 + x

Since x represents the amount of miles traveled, we can replace it with 5, 8, or 20.

3 + 5 = 8 dollars

3 + 8 = 11 dollars

3 + 20 = 23 dollars

Answer:-5

Step-by-step explanation:

The solution is in the attached file below

The gradient of the blue line that passes through the points (-1, 0) and (0, -5) is -5.

The Slope (gradient) is simply expressed as a change in y over the change in x.

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

The blue line in the graph runs through points (-1, 0) and (0, -5).

To find the gradient (slope) of the blue line passing through the points (-1, 0) and (0, -5), we use the slope formula.

Point (-1,0): x₁ = -1 and y₁ = 0

Point (0, -5): x₂ = 0 and y₂ = -5

Plug the coordinates into the above formula:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}\\\\m = \frac{-5 - 0}{0 - (-1)}\\\\Simplify:\\\\m = \frac{-5 - 0}{0 + 1}\\\\m = \frac{-5}{ 1}\\\\m = -5[/tex]

Therefore, the slope is -5.

Answer:

1,000

Step-by-step explanation:

In 1990, 500 donuts were sold per day. In the year 2000 the number of donuts sold went up by 200 to reach 700 donuts per day. Since we are to assume it's a linear relationship, it would mean that every ten years the number of donuts sold would go up by 200/day. In 2010 the shop would be selling 900 donuts per day. So, in 2015, The shop would be selling 1,000 donuts per day since only 5 years had passed since 2010 and after 5 years it would only go up by 100/day.

Answer: The length is 7, the width is 3.

Step-by-step explanation:

7*3 = 21 which is the area, also 7 and 3 are the only factors of 21.

7+7 is 14,

3+3 is 6

14 + 6 is 20 which is the perimeter.

Answer:

7.89474% decrease

Step-by-step explanation:

Solution:

Calculate percentage change

from V1 = 38 to V2 = 35

(V2−V1)|V1|×100

=(35−38)|38|×100

=−338×100

=−0.0789474×100

=−7.89474%change

=7.89474%decrease

Answer:

C. f(x) = (x-4)^2

Step-by-step explanation:

The function among the given option is f(x) = (x – 4)² hence option (C) will be the correct.

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.

Given that which one is a function so it is clear that f(x) = (x – 4)² is the best relation between x and f(x).

Hence this option will be the correct answer.

Answer:

€75.80

Step-by-step explanation:

Start with €467.

End up with €88.

Total amount withdrawn:

€467 - €88 = €379

The total amount was withdrawn in 5 equal amounts.

Each amount taken is:

€379 ÷ 5 = €75.80
