Distance between (-4, 6) and (3, 7)

sweet-ann [11.9K]

Answer: $5\sqrt{2}$

Step-by-step explanation:

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

plugging in the values we know:

$x_2 = 3,\ x_1=-4,\ y_2=7,\ y_1=6$

Therefore,

$Distance=\sqrt{(3-(-4))^2+(7-6)^2}$

$\rightarrow\ \sqrt{(3+4)^2+(1)^2}$

$\rightarrow\ \sqrt{7^2+1}$

$\rightarrow\ \sqrt{50}$

$\rightarrow\ \sqrt{5\times5\times2}$

$\rightarrow\ \large\boxed{5\sqrt{2}}$

The price p of a gallon of gas goes up to $0.05 cents on Friday. On Saturday the price goes down $0.03. Write a expression with

m_a_m_a [10]

Answer:

The expression with three terms to show the price of a gallon of gas on Saturday is ⇒ $p+0.05-0.03$

Step-by-step explanation:

Given:

Price of a gallon of gas in dollars = $p$

On Friday, the price goes up by = $0.05

On Saturday, the price goes down by = $0.03

To write an expression with three terms to show the price of a gallon of gas on Saturday.

Solution:

Initial price of a gallon given in dollars was = $p$

On Friday the price increased by $0.05.

So, the price on Friday in dollars can be given as = $p+0.05$

On Saturday, the price decreased by $0.03

So, the price on Saturday in dollars can be given as = $p+0.05-0.03$

Thus, the expression with three terms to show the price of a gallon of gas on Saturday is ⇒ $p+0.05-0.03$

Write an expression for the area of the shaded region in its simplest form. Show all of your steps.

patriot [66]

The area of the shaded region will be the area of the rectangle minus the area of the white square inside of it:

((x+10)(2x+5)) - ((x+1)(x+1))

First, FOIL both of the areas separately:

(2x^2 + 5x + 20x + 50) - (x^2 + x + x + 1)

Simplify within the parentheses by adding like terms:

(2x^2 + 25x + 50) - (x^2 + 2x + 1)

Now, subtract one equation from the other:

2x^2 + 25x + 50
-x^2 - 2x - 1
= x^2 + 23x + 49

This will be the equation for the area.
