Points S, L, and P on this grid represent the locations of the school, the library, and the park

Vlad [161]

The distance, in units, from the school to the library and then the distance from the library to the park is 15 units.

<h3>What is the length of any line on the graph?</h3>

The distance or length of any line on the graph,

D = √{(x₂ - x₁)² + (y₂ - y₁)²}

where,

d = distance/length of the line between point 1 and 2,

(x₁ , y₁) = coordinate of point 1,

(x₂ , y₂) = coordinate of point 2,

The distance from school to the library is SL, therefore,

$\rm SL = \sqrt{(4-0)^2 + (1-4)^2} = 5\ units$

The distance from library to the park is LP, therefore,

$\rm LP = \sqrt{(-4-4)^2 + (-5-1)^2} = 10\ units$

Now, the distance, in units, from the school to the library and then the distance from the library to the park is 15 units (10 units + 5 units).

A ferry operator takes tourists to an island.

Oksanka [162]

The fare of $(20 - 2.5) = $17.5 will maximize the total fare.

<h3>What is Differentiation?</h3>

Differentiation means the rate of change of one quantity with respect to another. The speed is calculated as the rate of change of distance with respect to time.

Here, The operator for a round-trip fare of $20, carries an average of 500 people per day.

It is estimated that 20 fewer people will take the trip, for each $1 increase in fare.

for $x increase in fare, 20x less people will take the trip and at that time the total fare F is given by

f(x) =(20 + x)(500 - 20x)

f (x) = 10000 + 100x - 20x²

For f(x) to be maximum, the condition is dy/dx = 0

100 - 40x = 0

⇒ x = 2.5

Thus, the fare of $(20 - 2.5) = $17.5 will maximize the total fare.

HELP ASAP!! IM FAILING AND I TRANSFER IN A WEEK. IDK HOW TO DO THIS:

X = W
y = L

<span>1. Write a function that could be used to find the garden’s length y in feet,
given its width x in feet. y =
</span>
A = x * y
20 = x * y
y = 20/x

<span>2. What happens to the length of the 20-square-foot garden as its width
gets closer and closer to zero feet?
</span>if W = 0 means x = 0, then Area is equal 0. You have <span>a straight length</span>
