1 answer:
UkoKoshka [18]3 years ago
5 0

Answer:

- 4\sqrt{2}

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Simplify \sqrt{18} using this rule

\sqrt{18}

= \sqrt{9(2)}

= \sqrt{9} × \sqrt{2} = 3\sqrt{2}

Then

- 2\sqrt{18} + 2\sqrt{2}

= - 2(3\sqrt{2} ) + 2\sqrt{2}

= - 6\sqrt{2} + 2\sqrt{2}

= - 4\sqrt{2}

The formula for finding the kinetic energy, E, of an object is given below, where m represents the mass and v represents the spe
Naily [24]

The formula for the velocity, v is √2E/m

<h3>What is kinetic energy?</h3>

Kinetic energy is half the mass multiplied by the square of the speed of the object

It is written thus;

Kinetic energy = 1/ 2 × m × v²

To solve for 'v' mean that we should make 'v' the subject of formula

E = 1/ 2 mv²

E = \frac{mv^2}{2}

cross multiply

2E = mv^2

To make 'v' the subject, we have

v = \sqrt{\frac{2E}{m} }

Thus, the formula for the velocity, v is √2E/m

Refer to the dog weights box-and-whisker plot in answering the question.
andriy [413]
The data is most concentrated in the third quarter (second section of the boxed area).

We know this because each quarter of the data is represented by a section of the graph, and the smaller the range, the more concentrated the data.

A local ice-cream shop sells ice-cream cones for $2.00, and customers can choose from the following options.
iris [78.8K]

Answer:

Option 5) The total cost of the cone

Step-by-step explanation:

We are given the following in the question:

Quantitative variable:

  • A variable that can be measured is known as a quantitative variable.
  • They may be discrete or continuous.
  • They can have numeric values.
  • For example: length, height, cost etc.

In the given situation the quantitative variables are:

1. Ice-cream flavor

It is not a quantitative variable since it cannot be measured.

2. Type of cone

It is not a quantitative variable since it cannot be measured.

3. Chocolate dipped or not

Since it would be answered with a yes or no, it is not a quantitative variable as it cannot be measured.

4. Sprinkles or not

Since it would be answered with a yes or no, it is not a quantitative variable as it cannot be measured.

5. The total cost of the cone

It is a quantitative variable as this would be expressed in numbers.
