Answer:

<h2>50 ft</h2>

Step-by-step explanation:

Use the Pythagorean theorem:

leg^2+leg^2=hypotenuse^2

We have

leg=40ft,\ leg=30ft,\ hypotenuse=x

Substitute:

40^2+30^2=x^2\\\\1600+900=x^2\\\\2500=x^2\to x=\sqrt{2500}\\\\x=50\ ft

You can see that you have a right triangle in the figure is a right triangle, which means that you can find the hypotenuse using the Pythagorean theorem:

d = \sqrt{30^2+40^2}=\sqrt{900+1600}=\sqrt{2500} = 50

Given that f(n) = 8n - 3 and g(n) = 3n - 10 <br> What is the value of f(-1)
padilas [110]

The value of f(-1) is -11 if the function f(n) = 8n - 3 after plugging the value of n is -1

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.


It is given that:

f(n) = 8n - 3

g(n) = 3n - 10

To find the value of f(-1) first plug n = -1 in the function f(n)

f(-1) = 8(-1) - 3

f(-1) = -8 - 3

f(-1) = -11

Thus, the value of f(-1) is -11 if the function f(n) = 8n - 3 after plugging the value of n is -1

RSB [31]

Answer:

Squares are defined by having all equivalent sides. Sometimes, rectangle have different lengths of side, thus not fitting the definition of a square. However, the definition of a rectangle is "an object with 2 pairs of sides parallel to eachother", therefore all squares fit the definition of a rectangle. Please mark brainliest :)
