Step-by-step explanation:
Since it is asking for a perpendicular line, we take the reciprocal of the slope in the given equation to use as the slope for the perpendicular line.
In y = x + 2, m = 1. However, for a perpendicular line we flip and multiply by a negative 1.
(Example: If m = 3, we would take the reciprocal of it and it turns into m = -1/3. If m = - 1/4, we would take the reciprocal of it and it turns into m = 4.)
So, the m = 1 turns into a m = -1.
Now, you can use the point (4,-1) to form a point-slope equation first.
y-(-1) = -1(x-4)
Then, use basic algebra to form a slope-intercept form equation.
y + 1 = -x + 4
y = -x +3
Answer:
37
Step-by-step explanation:
4x5= 20
20x2= 40
40-6= 34
34+3= 37
The volume of a cone is 1/3 the volume of a cylinder that perfectly encloses it.
So, the volume of a cone that fits perfectly inside the can is 15/3 = 5.
Answer:
$27.6
Step-by-step explanation:
The meal was $24, so you multiply 24 * .15 (which is your 15%) which equals 3.6. Add the 3.6 to 24 and your total is $27.6
The exact answer is 12 root 2, but you can also say approximately 17.
I got this by finding the square root of 369, and then 81. After finding these values, you get the equation...
a^2 + 9^2 = 369
a^2 + 81 = 369
a^2 = 288
And then I just found the square root of 288
