Answer:
Approx. 423.88 feet squared
Step-by-step explanation:
Hi
609.9 ⇒ 85%
x ⇒ 100%
85x = 100·(609.9)
85x = 60,990
x = (60,990)/85
x = 717.5294117... ≈ 717.53
85% of 717.53 ⇒ 0.85 × 717.53 = 609.9005 ≈ 609.9
Answer: 717.53
Answer:
With a vertex (h, k) at (0, 3) and given that a = -3, then the equation of this parabola in vertex form is as follows:
y = a(x - h)2 + k
y = -3(x - 0)2 + 3
y = -3x2 + 3
Step-by-step explanation:
Answer:
find the square of both numbers
13²=169
5²=25
minus the square
169-25 to get 144
find the square root of 144
✓144=12 the third side is 12
X = y + 12. You then substitute or plug in that from the first equation into the second equation. You get (y+12)+y=18, then you simplify to get your y value. In this case y = 3. The you can plug your y value into either equation. (x+3=18) or (x-3=12) or (x=3+12) either way you get x=15 and y=3.
