Distance Formula: $\displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Step-by-step explanation:

Step 1: Define

Identify

Point (5, 7)

Point (-4, 3)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-4 - 5)^2 + (3 - 7)^2}$
[√Radical] (Parenthesis) Simplify: $\displaystyle d = \sqrt{(-9)^2 + (-4)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{81 + 16}$
[√Radical] Simplify: $\displaystyle d = \sqrt{97}$
[√Radical] Approximate: $\displaystyle d \approx 9.8$

Write an equation for the sentence "The product of a number n and 7.7 equals 112.42." Solve for the variable.

pishuonlain [190]

Answer:

$7.7n=112.42$

$n=14.6$

Step-by-step explanation:

The product is the result obtained by multiplying two factors. Then, the sentence ""The product of a number n and 7.7 equals 112.42" can be expressed with the following equation:

$7.7n=112.42$

To solve for the variable "n", you has two apply the Division property of equality and divide both sides of the equation by 7.7

Therefore, the value of "n" is:

$\frac{7.7n}{7.7}=\frac{112.42}{7.7}\\\\n=14.6$
