Answer:

Eric, 9.8 meters.

Step-by-step explanation:

Use the distance formula with the given coordinate and each of the other coordinate.

\sqrt{(10-3)^{2}+(8-2)^{2} } Brooke

\sqrt{(-6-3)^{2}+(6-2)^{2} } Eric

\sqrt{(8-3)^{2}+(-6-2)^{2} } Cam

You'll see that Eric kicked the furthest distance with a distance of 9.8 meters.

Brooke kicked 9.2 meters and Cam kicked 9.4 meters. What does the distance formula really mean? When you solve for the distance between two points, you're really just creating a triangle between those two points, and you're actually looking for the hypotenuse. The slope that intersects your two points is the hypotenuse of the triangle you created.

What’s the answer??(SOMEONE PLEASE HELP ME)
aleksandr82 [10.1K]

We know that According to Algebra of Real Functions :  

If f and g are two real functions which are defined under the same domain then (\frac{f}{g})(x) = \frac{f(x)}{g(x)}

\implies Given\;Function\;is\;\frac{-1}{x\sqrt{3x - 9}}

Now we need find the Domain of this Function :

The Condition for Square Root to be defined is any Expression under it should be Greater than or Equal to Zero.

When Function is a Fraction, it Cannot be defined when the denominator becomes zero. Because when the denominator is zero, the fraction tends to ∞ (because anything divided by zero tends to ∞)

According to Above Conditions Described above, The Given Function is Definable only when the Expression which is under the Square Root is Greater than Zero and x ≠ 0

⇒ 3x - 9 > 0

⇒ 3x > 9

⇒ x > 3

⇒ The Domain of the Given Function is (3 , ∞)

The inequalities that match the given expressions are

x ≤ 95

x > 100

5x ≤ 100

20 ≤ x ≤100

respectively

<h3>Writing linear inequalities </h3>

From the question, we are to match the statements with the corresponding inequalities

  • Nora's height(x) is at least 5 cm less than Stacy who is 100 cm tall

x ≤ 100 -5

x ≤ 95

  • Temperature(x) is greater than the boiling point of water (100 °C)

x > 100

  • John buys x chocolates worth $5 each but he has only $100 in his pocket

5x ≤ 100

  • Ronny decided not to exceed 100L of water usage and ends up using at least 1/5th of this limit every day

x ≤ 100

and

x ≥ 1/5 × 100

x ≥ 20 ≡ 20 ≤ x

∴ 20 ≤ x ≤100

Hence, the inequalities that match the given expressions are

x ≤ 95

x > 100

5x ≤ 100

20 ≤ x ≤100

respectively
