Answer:
4,2 is tge answer due to the interaction point plus it says the solution is at the interaction.
Answer:
The lowest point is -100 meters, or 100 meters down
Step-by-step explanation:
D(x)=1/36(x-60)^2-100
This equation is in vertex form
y = a(x-h)^2 +k where (h,k) is the vertex
Since a is positive, the parabola opens up
The vertex is the minimum, which means it will be the lowest point
The vertex is (60,-100)
The lowest point is -100 meters, or 100 meters down
This is a square root problem since the patio is square.
A of a square is L x W or L^2 or W^2 - it's all the same.
So find the square root of 220 feet.
14.8323 We are to round to nearest hundreth which is the second position right of decimal. Look at the number to the right of that position.
It is a 2. So we do not round the number up.
14.83 is the rounded sq. ft of each side.
Check it!
14.83^2 = 219.92 Because we rounded, this number is not exact, but close.
We have
We subtract 11x on both sides and 7 on both sides
we sum like terms
Then we isolate the x
ANSWER
x=-1
The equation only have one solution
Answer:
17 sides
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here sum = 2700° , then
180°(n - 2) = 2700° ( divide both sides by 180° )
n - 2 = 15 ( add 2 to both sides )
n = 17
The polygon has 17 sides
