Hello!
To find the total cost, we will need to multiply the cost per square meter, by the total area. To find the area we will use the formula A=<span>πr</span>². We will use 3.14 for pi.
We know that 2.1 is our radius. We will square it and then multiply it by 3.14.
2.1²=4.41
4.41(3.14)≈13.85
Our area is about 13.85. Now we will multiply by $1.70 to find the total cost. This gives us about $23.55.
The total cost of the glass would be about $23.55.
I hope this helps!
Answer:
The answer to your question is: third option is correct
Step-by-step explanation:
Data
F (5, -1)
directrix y = 1
Then, after getting the graph, the vertix = (5, 0)
and p = 1
Formula
(x - h) ² = -4p(y - k)
(x - 5)² = -4(1)(y - 0)
(x - 5)² = -4y
y = (x - 5)² / -4
Answer:
Zeros of Functions. A zero of a function f is a number a such that f(a) = 0. In other words, a zero of f is a solution for the equation f(x) = 0.
Step-by-step explanation:
The three ordered pair for the solution is
(0,5), (1,3), (2,1)
