Answers:
a = 1/3
b = -6
c = 7
======================================================
Explanation:
The terms of the given expression rearrange to 
which is now in standard form (the exponents decrease when moving from left to right).
We can see that
a = 1/3
b = -6
c = 7
after matching that with the ax^2+bx+c form.
Alright, so first of all, you need to find the area of the circle that is part of the cone-shaped area so you can remove it. You need the formula:
where c = angle. Now plug in the answers, and you get:
.
This would then equal to 
.
now, essentially, the shape of this ENTIRE area is of 2 right triangles. Divide 120 by 2, you get 60 degrees. You have 2 60/30/90 triangles (shown in the bottom)
Now, what you need to do is to find the area of the entire thing by using the formula to calculate the right triangle area (A = (1/2)bh). You have
b, which is
6. To find the h, you use
tan(60) = x/6, which gives you
.
The area of one right triangle of this size would be =
Because 2 right triangles, multiply the area by 2 and get:
Now, remember the area of that circle in that total area? subtract it from the total area (
) by 12pi and you get 24.65.
The final answer is 24.65
Formula for area of a triangle is 1/2 x base x height.
musing the information given you have:
360 = 1/2 x base x 18
First multiply both sides by 2:
720 = base x 18
Now divide both sides by 18:
Base = 720/18
Base = 40 cm
Answer:
18
Step-by-step explanation:
Solve the separate part of the equation first
6(4) 6(-2) would equal 24-12
Add it back in to get: 10 - 4 + 24 - 12
-4-12 and 10+24 are the like terms so
10+24 = 34 and -4-12 = -16
Equation in the end: 34-16
Simplify that to: 34-16 = 18
Please add the three rational numbers, as I cannot solve.
