Answer:
Step-by-step explanation:
Hi there!
We want to find the distance between the points (2, -2) and (-4, 7).
To do that, we can use the distance formula.
The distance formula is given as 
, where 
and 
are points
We have everything needed to find the distance, but let's label the values of the points to avoid any confusion
Now substitute those values into the formula and solve
Simplify
Square the numbers under the radical
Add the numbers under the radical together
Simplify the square root
Hope this helps!
Answer:
1/12
Step-by-step explanation:
7 is one number out of 12 so if we take the one to the fraction is 1/12 aka simple easy math. if you want to simplify it would be impossible because 1 to 12 its impossible if it was 2/12 it would be 1/6, Sorry if i got the answer wrong.
Answer:
Undefined.
Step-by-step explanation:
When using the formula y2-y1/x2-x1, the result comes out as -4/0. Any number over a 0 is undefined.
Given that the central angle of a polygon is 18, then the number of sides of the polygon will be:
360/18
=20 sides
thus the side length will be:
144/20
=7.2 ft
hence the area will b given by:
p=s×n
a=s/[2tan(180)/n]
where:
Area=(a×p)/2
p=perimeter, s=side length, n=number of sides
p=7.2×20=144
a=7.2/[2tan (180/20)]=22.73
thus
A=(144×22.73)/2
A=1632.524 ft²
Answer: (x-5)/(x+1) and x cannot equal -1 because the denominator can't be zero.
Step-by-step explanation:
Factor the numerator:
(x+9)(x-5)
Factor the denominator:
(x+1)(x+9)
So you have
(x+9)(x-5)/(x+1)(x+9); see that you can cross out the (x+9) in both the numerator and denominator?
You're left with (x-5)/(x+1)
The only number that is restricted is -1, because that would make the denominator zero, which is a no no!!
