What best describes the distance between two points with coordinates (2,-3) and (-4,2)
Fed [463]

Answer:

Option c (7.8) is the correct alternative.

Step-by-step explanation:

The given points are:

(x₁, y₁) = (2, -3)

(x₂, y₂) = (-4, 2)

As we know,

The distance between two points will be:

= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

On substituting the values, we get

= \sqrt{(-4-2)^2+(2-(-3))^2}

= \sqrt{(-4-2)^2+(2+3)^2}

= \sqrt{(6)^2+(5)^2}

= \sqrt{36+25}

= \sqrt{61}

= 7.8 \ units

Jayce is a taxi driver.
REY [17]

Answer:

Jayce's fee (in dollars) for 10th drive on a certain day is K.

Step-by-step explanation:

It is given that M(n) models Jayce's fee (in dollars) for nth drive on a certain day.

We need to find the meaning of M(10)=K.

On comparing M(n) and M(10), we get the value of n is 10.

Since M(n) represents the Jayce's fee (in dollars) for nth drive on a certain day, therefore, M(10) represents the Jayce's fee (in dollars) for 10th drive on a certain day.

M(10)=K

It means Jayce's fee (in dollars) for 10th drive on a certain day is K.
