780 feet because 200 feet below sea level means -200 and 580 feet above sea level mean +580 so if you add 580 and the 200 you get the distance between the two points.
Answer:
The answer is 120 feet.
Step-by-step explanation:
The area of the field (A) is:
A = w · l (w - width, l - length)
It is known:
A = 12,000 ft²
l = w - 20
So, let's replace this in the formula for the area of the field:
12,000 = w · (w - 20)
12,000 = w² - 20
⇒ w² - 20w - 12,000 = 0
This is quadratic equation. Based on the quadratic formula:
ax² + bx + c = 0 ⇒
In the equation w² - 20w - 12,000 = 0, a = 1, b = -20, c = -12000
Thus:
So, width w can be either
or
Since, the width cannot be a negative number, the width of the field is 120 feet.
Hi there!
I calculated your equation on MathPapa Algebra calculator(you can find the link here:https://www.mathpapa.com/algebra-calculator.html) and I got the answer D. -24 - 57i
A reflection around the axis and is given by the following rule:
(x, y) ----> (-x, y)
Applying the rule to each vertex we have:
(-2, -4) ----> (2, -4)
(2, -5) ----> (-2, -5)
(-1, -8) ----> (1, -8)
Answer:
the coordinates of the vertices of the image ΔP'Q'R 'will be:
P '= (2, -4)
Q '= (- 2, -5)
R '= (1, -8)
Answer:
-5
Step-by-step explanation:
5 inches below ground. assuming ground is 0, then it would be -5
