Find the distance between (1, 4) and (3, 9). Round the answer to the nearest hundredth.
Romashka [77]
To calculate the distance between these two points, we use the Pythagorean theorem since the two points can form a right triangle when plotted where the hypotenuse would be the distance between these two. We do as follows:

d = √[(x2-x1)^2 + (y2-y1)^2]
d = √[(3-1)^2 + (9-4)^2]
d = √29 = 5.39 units 

The correct answer is A.

What is the value of f(−1) when f(x)=2x+2
mart [117]

Answer:

<h2>f( - 1) = 0</h2>

Step-by-step explanation:

f(x)=2x+2

To find f(−1) , substitute the values of x that's - 1 into f(x). That is for every x in f(x) replace it with - 1

That's

f( - 1) = 2( - 1) + 2 \\  =  - 2 + 2

We have the final answer as

f( - 1) = 0

Hope this helps you
