Plug in 0 for x
0 - 6y = 30
y = -5
Y intercept: (0,-5)
Plug in 0 for y
5x = 30
X = 6
X intercept: (6,0)
Area = base * height
Height = area / base
Height = base sin x
Where x = angle between side and the base

infinite geometric series
A1
= 880
r = 1 / 4
The sum of a geometric series in sigma
notation is:
n 1 - r^n
∑ Ai = A ----------- ; where A = A1
i = 1 1-r
When | r | < 1 the infinite sum exists and is equal to</span><span><span>:
∞ A
∑ Ai = ---------- ; where A = A1
i = 1 1 - r</span>
So, in this case</span><span><span>:
∞ 880
∑ Ai = -------------- = 4 * 880 / 3 = 3520 /3 = 1173 + 1/3
i = 1 1 - (1/4)</span> </span>
Answer: 1173 and 1/3
50.4$. All you have to do is multiply 63 by 0.20 ( which is another form on 20% h
63 x 0.20 would give us 12.6
Now you want to subtract that 12.6 from 63,
This will give you 50.4$ :)
2,6
4,4
6,2
im not gonna write a longer answer
