A local businessman bought a square plot of land. The sides of the lot measure 32 feet on each side. He decides to split the lot

Semmy [17]

Answer:

The sides of a right triangle all right triangles fall under the identity a^2 + b^2 = c^2. Thus, if you draw the picture, you know that both a and b will be 32 feet. You plug 32 in, and get 32^2 + 32^2 =2048. The square root of 2048=45.25 ft. Thus, the diagonal will be 45.25 feet.

Step-by-step explanation:

this is the correct formula to figure out equal sided right triangle

The midpoint of AB is M(-3, 0). If the coordinates of A are (1,-4), what are the coordinates of B?

zimovet [89]

Using the given information, the coordinates of B are (-7, 4)

<h3>Midpoint of a Line </h3>

From the question, we are to determine the coordinates of B.

Given a line with endpoints (x₁, y₁) and (x₂, y₂), then the midpoint of the line is

((x₁+x₂)/2, (y₁+y₂)/2)

From the given information,

The midpoint of AB is M(-3, 0)

and

The coordinates of A are (1,-4)

Let the coordinates of B be (x₁, y₁)

Then,

-3 = (1 + x₁)/2

-6 = 1 + x₁

x₁ = -6 -1

x₁ = -7

Also,

0 = (-4 + y₁)/2

0 = -4 + y₁

y₁ = 0 + 4

y₁ = 4

Hence, the coordinates of B are (-7, 4)

A salesperson earns $200 per week plus a commission equal to 4% of her sales. This week her goal is to earn no less than $450.

-Dominant- [34]

Based on the information given, the inequality of the amount of sales that she must have to reach her goal would be :
0.04 s + 200 ≥ 450

Given :

A function f(x) for different range of x.

To Find :

The value of f( -3 ) .

Solution :

We have to find the value of function at x = -3.

Now, in the given figure -3 lies in range x ≤ -2 and definition of function at that range is :

$f(x) = \dfrac{2}{x}$

So, putting value of x = -3 in above equation, we get :

$f(-3) = \dfrac{2}{-3} \\\\f(-3) = \dfrac{-2}{3}$

Hence, this is the required solution.
