Answer:
-2 sqrt(15)
Step-by-step explanation:
sqrt(-15) sqrt(-4)
We can use sqrt(ab) = sqrt(a) sqrt(b)
sqrt(-1) sqrt(15) * sqrt(-1) * sqrt(4)
We know the sqrt(-1) = i
i * sqrt(15) * i * 2
2i^2 sqrt(15)
i^2 = -1
-2 sqrt(15)
(2,4)
Step-by-step explanation:
I'm not sure in the slightest but with the formula I learned I think this is correct
<u>Answer</u>
See below
Step-by-step explanation:
The given line has equation
The slope intercept form is
The slope of this line is
The line perpendicular to this line has slope
If this line passes through (5,-4), the point-slope form is
The slope-intercept form is
The standard form is
2x+5y=-10
Answer:
5
Step-by-step explanation:
The easiest way to do this problem is to know that the hypotenuse of a 45-45-90 triangle is equal to times the length of a leg.
So, in your problem the hypotenuse = (5) = 5. Another way to solve the problem is to use the Pythagorean theorem, but that is a longer way to solve it.
7/5 - 10/5 = -3/5
I hope this helps.
