Answer:

Yes

Step-by-step explanation:

A slanted straight line is one-to-one: It passes the "horizontal ilne test." This means that any line drawn horizontally through the given line intersects that line only once. The significance of this is that the given line/function has an inverse. y = x is one-to-one and has the inverse y = x. y = 2x is one-to-one and has the inverse y = (1/2)x.

What is the length of the hypotenuse of the triangle?<br> 7 ft<br> 4 ft

stepladder [879]

Answer:

√65 ft = 8.1 ft

Step-by-step explanation:

We solve using Pythagoras Theorem

c² = a² + b²

c = √a² + b²

Where c = Length of the Hypotenuse

a = 4ft , b = 7ft

Hence

c = √4² + 7²

c = √16 + 49

c = √(65)

c = 8.0622577483 ft

Approximately = 8.1 ft

Therefore, the length of the hypotenuse is √65 ft = 8.1 ft

The mean of the answer is 20.5 because you add all of the number together and divide by 6 because there's 6 numbers.
