Answer:

Correct answer: sa · sb = 2/3 · (- 3/2) = - 1

Step-by-step explanation:

Given:

line A - (x₁, y₁) = (3, -4) and (x₂, y₂) = (6, -2)

line B - (x₁, y₁) = (-1, 5) and (x₂, y₂) = (1, 2)

The slope is calculated using the following formula:

s = (y₂ - y₁) / (x₂ - x₁)

sa = (-2 - (-4)) / (6 - 3) = (-2 + 4) / 3 = 2 / 3

sa = 2 / 3

sb = (2 - 5) / (1 - (-1)) = -3 / 2

when lines are perpendicular to each other then the slopes are in the next relationship:

sa · sb = - 1

we will check:

sa · sb = 2/3 · (- 3/2) = - 1

The answer to this question

Vesnalui [34]

From indices : when you have a fraction like 3⁶/5

we can also write it as (5√3)^6

and we were given (c√a )^b

meaning that anywhere the letters are, we put them as the numbers there.

therefore: a = 3 , b = 6 , c = 5

Hope this helps and you understood it.

you're super free to ask any more questions eh.

Good luck ✅.

The length of each side of the square is 3 ft.

<u>Step-by-step explanation:</u>

We have , A composite figure is formed by combining a square and a triangle. Its total area is 52.5 ft. The area of the triangle is 43.5 ft . We know that area of a square = $length^{2}$ . According to question:

area of square = $length^{2}$

area of triangle = 43.5 ft

total area = 52.5 ft.

Total area = area(square+triangle)

⇒ $43.5 + (Length)^{2} = 52.5$

⇒ $(Length)^{2} = 52.5- 43.5$

⇒ $(Length)^{2} = 9$

⇒ $(Length) = \sqrt{9}$

⇒ $Length= 3$

Therefore, the length of each side of the square is 3 ft.

Semmy [17]

Step-by-step explanation:

we need to find how much 14/70 is equal to ? over 100

100/70=1.42857142857

14x1.42857142857=20

Therefore she drinks 20/100 she drinks before she goes on a ride.

or 20%
