Answer:
4 Km behind.
Step-by-step explanation:
1. Draw a graph
2. make Dave Edith and Foley
3. 8-0 is 8 and 12-8 is 4
Answer:
Two of these statements are true.
The function equals x^2 over the interval −∞ < x ≤ 0.
The function equals √x over the interval 0 ≤ x < ∞.
Step-by-step explanation:
If we look at the parent function of we see that function looks like a U shaped graph and in your graph we see it is the same as your graph from the interval (-∞,0).
If we look at the parent function of we see that the
function looks like your graph from the interval (0,∞).
Suggestion:
I suggest memorizing every graph of parent functions that is introduced to you in math. This can help you visually with many problems in mathematics, and help you conceptualize material better. I also suggest looking up the definition of every word that may be unfamiliar to you like "interval" and "parent function". This will help you understand more advanced math notations and vocabulary in the future.
Answer: 262144
Step-by-step explanation: You can calculate & draw it out. Then, add the values in the second-to-bottom row of the picture below.
Translating into a mathematical equation:
n + n^2 = 72
Rewriting, n^2 + n - 72 = 0
Factoring, (n+9)(n-8) = 0
Solving for n: n = -9 or n = 8
You must check both answers before accepting one, the other or both.
Example: suppose we check out n = 8. Then 8 + 8^2 = 72 is true, and n = 8 is a solution. Is n = -9 a solution? Try it.
If the garden is square, then the perimeter would be 90. 15(2)+30(2)=90
810/90=9
So it would cost $9 per foot.
