Answer:
A. 22 feet
Step-by-step explanation:
22 + 22 + 22 + 22 = 88 the formula is
Length x Width X length X Width but since it is a square just divide
Hope this helps
Answer:
Step-by-step explanation:
Solve as requested in the question, round each number:
The sum is:
I'm not sure about the answer myself, but here is how I think you would solve it.
First, you'd graph the circle. I recommend using a graphing calculator to do so.
Since the line is tangent and is meeting at the point (1,2) we can keep this in mind when creating our equation. From there, using what you know try to find a second point on the line.
From here it becomes normal algebra, use slope intercept form to create an equation.

The sum of the first four terms of the sequence is 22.
In this question,
The formula of sum of linear sequence is
The sum of the first ten terms of a linear sequence is 145
⇒
⇒ 145 = 5 (2a+9d)
⇒
⇒ 29 = 2a + 9d ------- (1)
The sum of the next ten term is 445, so the sum of first twenty terms is
⇒ 145 + 445
⇒
⇒ 590 = 10 (2a + 19d)
⇒
⇒ 59 = 2a + 19d -------- (2)
Now subtract (2) from (1),
⇒ 30 = 10d
⇒ d =
⇒ d = 3
Substitute d in (1), we get
⇒ 29 = 2a + 9(3)
⇒ 29 = 2a + 27
⇒ 29 - 27 = 2a
⇒ 2 = 2a
⇒ a =
⇒ a = 1
Thus, sum of first four terms is
⇒
⇒
⇒ S₄ = 2(2+9)
⇒ S₄ = 2(11)
⇒ S₄ = 22.
Hence we can conclude that the sum of the first four terms of the sequence is 22.
